Increased Ir–Ir Interaction in Iridium Oxide during the Oxygen Evolution Reaction at High Potentials Probed by Operando Spectroscopy. ACS Catalysis, 2021; 11 (15): 10043 DOI: 10.1021/acscatal.1c02074

Using energy from solar modules and wind turbines, water can be split by electrolysis into its constituents hydrogen and oxygen without producing any dangerous emissions. As the availability of energy from renewable sources varies when producing green, i.e. CO2-neutral, hydrogen, it is very important to know the behavior of the catalysts under high loading and dynamic conditions. “At high currents, strong oxygen bubble evolution can be observed on the anode, which aggravates measurement. It has made it impossible so far to obtain a reliable measurement signal,” says the first author of the study, Dr. Steffen Czioska from KIT’s Institute for Chemical Technology and Polymer Chemistry (ITCP). By combining various techniques, the researchers have now succeeded in fundamentally investigating the surface of the iridium oxide catalyst under dynamic operation conditions. “For the first time, we have studied the behavior of the catalyst on the atomic level in spite of strong bubble evolution,” Czioska says. The American Chemical Society (ACS) considers the importance of KIT’s publication to the international community to be high and recommends it as the ACS Editor’s Choice.

X-ray Absorption Spectroscopy with Synchrotron Light

For catalysis, researchers from KIT’s ITCP, the Institute of Catalysis Research and Technology, and the Electrochemical Technologies Group of the Institute for Applied Materials combined X-ray absorption spectroscopy for the highly precise investigation of modifications on the atomic level with other analysis methods. “We have observed regular processes on the catalyst surface during the reaction, because all irregularities were filtered out — similar to slow speed shooting on a road at night — and we have also pursued dynamic processes,” Czioska says. “Our study reveals highly unexpected structural modifications connected to a stabilization of the catalyst at high voltages under dynamic loading,” the chemist adds. Iridium oxide dissolution is reduced, the material remains stable.

Findings Will Contribute to Better and More Efficient Catalysts

Understanding of the processes on the catalyst surface paves the way to further investigation of catalysts at high electric potentials and will contribute to the development of improved and more efficient catalysts meeting the needs of the energy transition, Czioska points out. The study is part of the “Dynakat” priority program funded by the German Research Foundation. This collaboration of more than 30 research groups from all over Germany is coordinated by Professor Jan-Dierk Grunwaldt from ITCP.

Green hydrogen is deemed an environmentally compatible chemical energy storage material and, hence, an important element in the decarbonization of e.g. steel and chemical industries. According to the National Hydrogen Strategy adopted by the Federal Government in 2020, reliable, affordable, and sustainable production of hydrogen will be the basis for its future use.

["content"]=> array(1) { ["encoded"]=> string(3336) "

SEOUL – YouTuber and former entertainment reporter Kim Yong Ho has again exposed the scandals of artists through the YouTube Garo Sero Institute. This time, he revealed information about Park Yoochun.

On August 22, Kim conducted a live broadcast via YouTube with the theme of the discussion: ‘Unreasonable Park Yoochun’. He opened the live broadcast by discussing TVXQ and BIGBANG.

“I am very proud, the world can know South Korea through them. But, look at the fate of the two groups now. They have to face destruction and deal with prostitution, drugs, and other cases,” he said as quoted from Allkpop, Wednesday (25/8/2021).

Kim added, “As a reporter who watched their growth from debut, I am very sad and regret the current condition of the former members of the two groups.”

Since starting his career, Kim said, Park Yoochun has been very flirtatious with women. Mentally, the former TVXQ member is burdened with various family problems.

“It all started with Hwang Ha Na dating Kim Jae Joong, then turned to his partner at JYJ, Park Yoochun. Playgirls like Ha Na dominate Yoochun, who is mentally unstable.”

From that story, Kim Yong Ho then revealed another surprising news about the 35-year-old idol. A fan confessed, sending a message to strengthen Yoochun via Instagram.

  1. Philipp Kaufmann, Matthew E. Wolak, Arild Husby, Elina Immonen. Rapid evolution of sexual size dimorphism facilitated by Y-linked genetic variance. Nature Ecology & Evolution, 2021; DOI: 10.1038/s41559-021-01530-z

Females and males typically differ in many ways in their morphology, physiology and behaviour. How such sex differences, known as sexual dimorphism, evolve is a puzzle because females and males share the same set of genes and an evolutionary change in one sex should cause a correlated change even in the other sex, thereby preventing sex differences from evolving. The new study shows that even small amounts of genetic differences between the sexes can facilitate the evolution of sexual dimorphism such that it can evolve in just a few generations.

“Our experiments show that the autosomes as well as both sex chromosomes, the X and Y, can harbor genetic variation important for sexual dimorphism, but the Y chromosome alone can alter the sex difference in size by as much as 30 percent. This is remarkable because in these beetles the Y chromosome contains just a handful of genes and represents a very small fraction of the genome, just like in humans. Many have thought that the Y only affects the most important reproductive processes in males, namely sperm production. Our findings suggest that the Y chromosome may have a broader role than previously appreciated,” says Philipp Kaufmann, a PhD student at the Uppsala University’s Department of Ecology and Genetics and the first author of the study.

The evolution of sexual dimorphism is however not only dependent on where in the genome genetic variation resides, but also on how natural and sexual selection can act on it. With the help of lab evolution, the research team showed that sexual size dimorphism could evolve when selecting on male size, but that when selection acted only on females, the shared part of the genome caused a correlated evolutionary response in males preventing dimorphism from evolving.

“The most drastic change in sexual dimorphism, an increase by 50 percent in only ten generations, occurred when we applied selection sexually antagonistically — favoring the opposite body size in the two sexes. This shows that under right kind of selection sex differences can clearly evolve rapidly, perhaps more easily than was previously thought,” says Elina Immonen, Assistant Professor at the Department of Ecology and Genetics, Uppsala University, and the principle investigator of the study.

“Combining information of what kind of genetic variation is available to selection with different forms of selection is a powerful way to test the determinants of evolution of sex differences. By isolating the effect of Y chromosome variation from the rest of the genome, we could directly demonstrate how large the effect of the Y chromosome is, something we didn’t expect to see when we started the work and this has helped understand how sexual dimorphism has evolved in this species. Future work will tell us more regarding how the Y chromosome can have such a large effect on males and how general its role is in the evolution of sex differences across taxa,” Immonen concludes.

More about the experiments

In their study, the researchers characterized the genetic architecture of body size in males and females by creating a large pedigree of over 8,000 beetles (the seed beetle Callosobruchus maculatus). This multi-generational family tree was used to quantify autosomal and sex chromosome linked genetic variation in body size. The use of artificial selection allowed testing how different forms of selection affect the evolution of size dimorphism and included selection acting only on males, only on females, or acting sexually antagonistically (in the opposite directions) in the two sexes. After ten generations of selection, the sexual size dimorphism was compared between the selection lines and the ancestral pedigree population. These two experiments clearly indicated that the Y chromosome play an important role in determining male response to selection. In order to test further the effect of the Y linked variation in isolation from variation in the rest of the genome, the research team carried out a third experiment. They isolated the effect of the Y chromosome on sexual size dimorphism in these beetles by introducing the different Y chromosomes into a genetically identical background. In other words, creating beetles that are identical twins to each other except for the Y chromosome.

Journal Reference:

  1. Eun Hye Kwon, Hyejin An, Min Bum Park, Min Kim, Yeong Don Park. Conjugated polymer–zeolite hybrids for robust gas sensors: Effect of zeolite surface area on NO2 sensing ability. Chemical Engineering Journal, 2021; 420: 129588 DOI: 10.1016/j.cej.2021.129588

Of much recent research interest in this field are the novel organic field-effect transistor-based (OFET) sensors, which are highly sensitive, flexible, and lightweight, opening doors to portable gas sensors even on e-skins. However, OFETs are unstable, and therefore not durable, at room temperature. This limits their applicability and makes them inferior to existing inorganic sensors, which nonetheless, do not possess any of the flexibility and light weight of organic sensors.

Bridging the organic-inorganic gap, scientists from Incheon National University, Korea, led by Prof. Yeong Don Park, have created hybrid OFETs using a organic conjugated polymer and variations of an inorganic nanoporous material, zeolite. Their study was made available online on 6 April 2021 and will be published in Volume 420 Part 1 of Chemical Engineering Journal on 15 September 2021.

“The high degree of porosity in zeolite results in an exceptionally high specific surface area and, in turn, a strong adsorption response for small gas molecules. This also helps it adsorb the molecules in air that oxidize (react with) the gas sensor to destabilize it and reduce its durability.” explains Prof. Park. Their material boasts not only high durability, but also high sensitivity.

The team fabricated two OFET-based NO2 sensors using a combination of the conjugated polymer, poly(3-hexylthiophene) (P3HT) and one of two zeolite materials, PST-11 or Omega. They examined the sensing performances of both OFETs when exposed to NO2 gas. The hybridization provided the polymer with an orderly structure which in turn led to efficient interactions with the gas molecules and, consequently, high sensitivity. Among the two, the scientists observed that the PST-11-P3HT film was more sensitive to NO2 than the Omega-P3HT film due to a larger specific surface area.

Overall, Prof. Park explains: “Our approach represents a new way of conceptualizing the design and development of sensors. If our research is refined further, people can easily detect harmful gases in real time.” Speaking of his vision, he says: “Our devices can be integrated with wearable devices such as smart watches and e-skins to allow people to know about air pollution levels in areas other than industrial sites.”

While a pollution-free world is our end goal, it certainly wouldn’t hurt to stay safe while we get there.

August 25, 1991 was the perfect day. What all sports fans and journalists have always dreamed of. A day that seemed unrepeatable and that instead has been passed in glory, from the now unforgettable Last August 1st of the double gold of Tamberi-Jacobs at the Tokyo Games. Yet that perfect day, today, exactly3 30 years ago, has remained forever in the memories of true sportsmen.

Summer is ending and Sunday 25 August 1991 they are all at the beach for one of the last baths of the season. Remembering that day is an act of faith, of passion. Of pure love for sport. By mid-morning it’s already there Loris Capirossi who wins the 125 motorcycle world championship in Brno. Still in the morning, from Tokyo, the World Athletics Championships, with the stellar final of the 100 flat meters, which Carl Lewis wins with the world record (9 ”86). An unforgettable final: Burrell 2nd, Mitchell 3rd, Christie, Friederiks, Stewart all under 10 ”. At lunchtime, the magical moment of Peppe and Carmine Abbagnale who win the seventh rowing world championship in two with in Vienna, led by Peppino Di Capua.

It is the perfect day, the day of sports days, there is also room for Josefa Idem who wins bronze at the World Championships in the K1 500 canoe meters, first time as an Italian athlete.

Nobody imagines that that Belgian Grand Prix will go down in history for Schumi’s very first time.

While the World Athletics Championships are going crazy, the European Swimming Championships in Athens end on 25 August. A magical sport crossover that rarely happens.

August 25, 1991 was the perfect day. What all sports fans and journalists have always dreamed of. A day that seemed unrepeatable and that instead has been passed in glory, from the now unforgettable Last August 1st of the double gold of Tamberi-Jacobs at the Tokyo Games. Yet that perfect day, today, exactly3 30 years ago, has remained forever in the memories of true sportsmen.

Summer is ending and Sunday 25 August 1991 they are all at the beach for one of the last baths of the season. Remembering that day is an act of faith, of passion. Of pure love for sport. By mid-morning it’s already there Loris Capirossi who wins the 125 motorcycle world championship in Brno. Still in the morning, from Tokyo, the World Athletics Championships, with the stellar final of the 100 flat meters, which Carl Lewis wins with the world record (9 ”86). An unforgettable final: Burrell 2nd, Mitchell 3rd, Christie, Friederiks, Stewart all under 10 ”.

  1. B.A. Peak, R.M. Flowers, F.A. Macdonald, J.M. Cottle. Zircon (U-Th)/He thermochronology reveals pre-Great Unconformity paleotopography in the Grand Canyon region, USA. Geology, 2021; DOI: 10.1130/G49116.1

The research comes closer to solving a puzzle, called the “Great Unconformity,” that has perplexed geologists since it was first described nearly 150 years ago.

Think of the red bluffs and cliffs of the Grand Canyon as Earth’s history textbook, explained Barra Peak, lead author of the new study and a graduate student in geological sciences at CU Boulder. If you scale down the canyon’s rock faces, you can jump back almost 2 billion years into the planet’s past. But that textbook is also missing pages: In some areas, more than 1 billion years’ worth of rocks have disappeared from the Grand Canyon without a trace.

Geologists want to know why.

“The Great Unconformity is one of the first well-documented geologic features in North America,” Peak said. “But until recently, we didn’t have a lot of constraints on when or how it occurred.”

Now, she and her colleagues think they may be narrowing in on an answer in a paper published this month in the journal Geology. The team reports that a series of small yet violent faulting events may have rocked the region during the breakup of an ancient supercontinent called Rodinia. The resulting havoc likely tore up the earth around the canyon, causing rocks and sediment to wash away and into the ocean.

The team’s findings could help scientists fill in missing pieces of what happened during this critical period for the Grand Canyon — today one of North America’s foremost natural wonders.

“We have new analytical methods in our lab that allow us to decipher the history in the missing window of time across the Great Unconformity,” said Rebecca Flowers, coauthor of the new study and a professor of geological sciences. “We are doing this in the Grand Canyon and at other Great Unconformity localities across North America.”

Beautiful lines

It’s a mystery that goes back a long way. John Wesley Powell, the namesake of today’s Lake Powell, first saw the Great Unconformity during his famed 1869 expedition by boat down the rapids of the Colorado River.

Peak, who completed a similar research rafting trip through the Grand Canyon in spring 2021, said that the feature is stark enough that you can see it from the river.

“There are beautiful lines,” Peak said. “At the bottom, you can see very clearly that there are rocks that have been pushed together. Their layers are vertical. Then there there’s a cutoff, and above that you have these beautiful horizontal layers that form the buttes and peaks that you associate with the Grand Canyon.”

The difference between those two types of rocks is significant. In the western part of the canyon toward Lake Mead, the basement stone is 1.4 to 1.8 billion years old. The rocks sitting on top, however, are just 520 million years old. Since Powell’s voyage, scientists have seen evidence of similar periods of lost time at sites around North America.

“There’s more than a billion years that’s gone,” Peak said. “It’s also a billion years during an interesting part of Earth’s history where the planet is transitioning from an older setting to the modern Earth we know today.”

A continent splits

To explore the transition, Peak and her colleagues employed a method called “thermochronology,” which tracks the history of heat in stone. Peak explained that, when geologic formations are buried deep underground, the pressure building on top of them can cause them to get toasty. That heat, in turn, leaves a trace in the chemistry of minerals in those formations.

Using this approach, the researchers conducted a survey of samples of rock collected from throughout the Grand Canyon. They discovered that the history of this feature may be more convoluted than scientists have assumed. In particular, the western half of the canyon and its eastern portion (the part that tourists are most familiar with) may have undergone different geologic contortions throughout time.

“It’s not a single block with the same temperature history,” Peak said.

Roughly 700 million years ago, basement rock in the west seems to have risen to the surface. In the eastern half, however, that same stone was under kilometers of sediment.

The difference likely came down to the breakup of Rodinia, a gigantic land mass that began to pull apart at about the same time, Peak said. The researchers results suggest that this major upheaval may have torn at the eastern and western halves of the Grand Canyon in different ways and at slightly different times — producing the Great Unconformity in the process.

Peak and her colleagues are now looking at other sites of the Great Unconformity in North America to see how general this picture might be. For now, she’s excited to watch geologic history play out in one of the country’s most picturesque landscapes.

“There are just so many things there that aren’t present anywhere else,” she said. “It’s a really amazing natural lab.”

Other coauthors of the new study included John Cottle and Francis Macdonald of the University of California, Santa Barbara.

  1. Daniela Weber, Elke Loichinger. Live longer, retire later? Developments of healthy life expectancies and working life expectancies between age 50–59 and age 60–69 in Europe. European Journal of Ageing, 2020; DOI: 10.1007/s10433-020-00592-5

Life expectancy has steadily been increasing in many countries around the world due to, among others, advances in healthcare and people adopting healthier lifestyles. At the same time, fertility has been declining or stabilized at low levels, leading to a marked increase in the share of older adults in these populations. This situation poses a risk to financial sustainability in several areas of social security systems, one of them being pension systems, as most European countries provide public pensions to their citizens. Retirement ages and measures to support longer working lives are being widely discussed at the country, as well as the European Union level, and many countries have already initiated and passed policy changes to gradually increase the official retirement age. One pertinent question that has however surfaced in this context is how large the potential is to increase working lives further given people’s health status.

In their study published in the European Journal of Aging, IIASA researcher Daniela Weber and Elke Loichinger from the Federal Institute for Population Research in Germany investigated whether there is potential to generally increase the retirement age. They based their analysis on the relationship between working life expectancy and three health expectancies that represent health aspects important for work ability and employability between ages 50 and 59, as well as ages 60 and 69 for women and men in Europe.

“There are several studies on the relationship between retirement and health on the individual level, but studies on the population level are rare and we were surprised to find that differences in health and working life expectancies had not been quantified before. We wanted to see how large the potential is to increase working lives further, given people’s health status and also how this potential differs between men and women for different age groups and between different socioeconomic groups,” explains Loichinger.

To this end, the researchers analyzed the relationship between working life expectancy and health expectancy, differentiating between three health dimensions, namely physical health, cognitive health, and general health. Moreover, they analyzed heterogeneity in working life expectancy and all three health outcomes by education. The analysis specifically focused on age groups 50-59 and 60-69 as those are, and will continue to be, most affected by future increases in retirement ages.

The findings indicate that, overall, there is potential to increase the expected number of economically active years for both men and women between the ages 60 and 69. An education-specific analysis however revealed large differences between socioeconomic subgroups of the population when it comes to the size of this potential. For instance, 60-year old men in Sweden with low education can expect to work 4.2 more years. This increases to six more years when they have a tertiary-level education. With regard to their physical health, men with a low level of educational attainment can expect 8.4 years in good health and 8.7 years when they have a tertiary-level education. In Bulgaria, men of the same age with a tertiary level of education can expect to work 4.5 more years while expecting 5.7 more years in good physical health. Their counterparts with a low level of educational attainment can expect only 2.7 years in good physical health, during which they are also expected to work.

“The heterogeneity between education groups in terms of health and the ability to work beyond currently observed labor market exit ages has to be taken into account when working lives are being extended. Our results indicate potential to extend working lives beyond current levels. However, significant differences in the expected number of years in good health between persons with different levels of education require policies that account for this heterogeneity,” Weber concludes.

Fluc‐EGFP reporter mice reveal differential alterations of neuronal proteostasis in aging and disease. The EMBO Journal, 2021; DOI: 10.15252/embj.2020107260

Proteins fulfill all important tasks in our body: They transport substances, protect against diseases, support the cell and catalyze chemical reactions — to name just a few. With the building instructions in our genetic code, every protein can be produced as a long chain of amino acids. However, that’s not the end of the story: in order to perform their vital functions, proteins have to fold into complex 3D structures.

Each cell contains a whole machinery that helps proteins to fold, corrects folding errors and discards misfolded proteins. As a kind of quality control, the system thus contributes to proteostasis — the controlled function of all proteins.

In healthy cells, this quality control works very well. With age, however, it gradually deteriorates. This can become a problem, especially for nerve cells. These cells do not renew themselves and are therefore dependent on stable protein function throughout their lives. In fact, neurodegenerative diseases such as Alzheimer’s, Parkinson’s or Huntington’s disease have in common that certain misfolded proteins overload the quality control system and are not disposed of. These proteins accumulate, clump together and eventually form deposits in the brain tissue. Depending on the disease, this can lead to impaired memory or muscle control — with no chance of a cure so far. The ability to enhance the neurons’ quality control could thus present a promising therapeutic option.

In order to study the quality control defects in the individual diseases in more detail, scientists led by Irina Dudanova developed a new mouse line. With these animals, the state of proteostasis can be visualized in the mammalian brain for the first time.

The researchers introduced the protein that normally makes fireflies glow into the neurons of the mouse. Optimized to the body temperature of the beetle, the protein needs constant help to fold in “warmer” mammals. Only then can it adopt its correct structure and produce light. In order to precisely track the location of the luminescent protein in the cell, the scientists additionally labeled it with a dye. In this way, they showed that the protein is evenly distributed and glows in healthy neurons. However, if the protein quality control is overstrained, the beetle protein makes clumps and no longer glows as strongly. The beetle protein therefore serves as a proteostasis sensor.

The researchers then crossed the newly developed mouse line with mice that represent different neurodegenerative diseases. In mice showing signs of Alzheimer’s disease, the luminescent protein formed clumps, signaling strong proteostasis disturbance. Interestingly, this was not the case in Chorea Huntington mice. Irina Dudanova relates, “The different results were quite surprising. When we had a closer look at the possible reasons, we found that both the misfolded proteins themselves and their location in the cell play an important role.”

Variation within the cell

While the misfolded protein in the Alzheimer’s model forms deposits in the cell body, it clumps together in the cell nucleus in the Huntington’s mice. Accordingly, protein quality control and its capacity can vary greatly within a cell. “This shows how complex protein quality control is and how different its alterations can be in individual neurodegenerative diseases,” explains Irina Dudanova.

With the new mouse line, scientists now have a tool to specifically investigate this complexity — both in healthy and in diseased neurons. Irina Dudanova and her team plan to investigate other neurodegenerative diseases and to find out whether different cell types in the brain are affected at different rates. In addition, the mouse line could help to assess the effectiveness of different therapies for neurodegenerative diseases.

Fluc‐EGFP reporter mice reveal differential alterations of neuronal proteostasis in aging and disease. The EMBO Journal, 2021; DOI: 10.15252/embj.2020107260

Proteins fulfill all important tasks in our body: They transport substances, protect against diseases, support the cell and catalyze chemical reactions — to name just a few. With the building instructions in our genetic code, every protein can be produced as a long chain of amino acids. However, that’s not the end of the story: in order to perform their vital functions, proteins have to fold into complex 3D structures.

Each cell contains a whole machinery that helps proteins to fold, corrects folding errors and discards misfolded proteins. As a kind of quality control, the system thus contributes to proteostasis — the controlled function of all proteins.

In healthy cells, this quality control works very well. With age, however, it gradually deteriorates. This can become a problem, especially for nerve cells. These cells do not renew themselves and are therefore dependent on stable protein function throughout their lives. In fact, neurodegenerative diseases such as Alzheimer’s, Parkinson’s or Huntington’s disease have in common that certain misfolded proteins overload the quality control system and are not disposed of. These proteins accumulate, clump together and eventually form deposits in the brain tissue. Depending on the disease, this can lead to impaired memory or muscle control — with no chance of a cure so far. The ability to enhance the neurons’ quality control could thus present a promising therapeutic option.
