How electrons and atomic nuclei make OLEDs glow Organic light-emitting diodes (OLEDs) can be used to generate light from electricity in a cost-effective and sustainable manner. Central to this is the use of efficient dye molecules. A team of theoretical chemists from the University of Vienna has now elucidated how these molecules function by means of computer simulations.

It is known that toxins in tobacco smoke can change our DNA - but where exactly in the genome they do this has been a mystery. A new approach developed by researchers at ETH Zurich now brings light into the darkness. In the future, this could make it easier than ever to determine the safety of many chemical substances.

A team from Lawrence Berkeley National Laboratory ÜBerkeley Lab) and Florida State University has designed a new blueprint for solid-state batteries that are less dependent on specific chemical elements, particularly critical metals that are challenging to source due to supply chain issues. Their work, reported recently in the journal Science , could advance solid-state batteries that are efficient and affordable.

An international team of researchers has developed a new technique to enhance the durability of inverted perovskite solar cells - an important step toward commercialization of an emerging photovoltaic technology that could significantly reduce the cost of solar energy. Unlike traditional solar cells, which are made from wafers of extremely high-purity silicon, perovskite solar cells are built from nano-sized crystals.

Researchers have developed an extraordinary protection against corrosion after a chance discovery. It glows in places where it is not damaged, repairs itself - and can be reused multiple times. Skyscrapers, bridges, ships, aeroplanes, cars - everything humans make or build sooner or later decays. The ravages of time are known as corrosion; nothing is safe from it.

MIT chemists found a way to cut the carbon footprint of producing white phosphorus, an ingredient in many consumer products. Close Phosphorus is an essential ingredient in thousands of products, including herbicides, lithium-ion batteries, and even soft drinks. Most of this phosphorus comes from an energy-intensive process that contributes significantly to global carbon emissions.

A team of scientists led by Professor Tanja Gulder at Leipzig University's Institute of Organic Chemistry, together with colleagues from the University of Regensburg, has developed a simplified and efficient method for the artificial production of terpenes. Terpenes are a very extensive and diverse class of natural products that perform a wide range of functions in nature and are also used industrially.

Since the 1970s, scientists have known that copper has a special ability to transform carbon dioxide into valuable chemicals and fuels. But for many years, scientists have struggled to understand how this common metal works as an electrocatalyst, a mechanism that uses energy from electrons to chemically transform molecules into different products.

An MIT team is working to harness combustion to yield valuable materials, including some that are critical in the manufacture of lithium-ion batteries. Close For more than a century, much of the world has run on the combustion of fossil fuels. Now, to avert the threat of climate change, the energy system is changing.

A new method for removing the greenhouse gas from the ocean could be far more efficient than existing systems for removing it from the air. Close As carbon dioxide continues to build up in the Earth's atmosphere, research teams around the world have spent years seeking ways to remove the gas efficiently from the air.

The atomic structure of solid substances can often be analysed quickly, easily and very precisely using X-rays. However, this requires that crystals of the corresponding substances exist. Chemist Professor Oliver Oeckler from Leipzig University and his team are developing methods to make this possible even for very small crystals that cannot be seen with the naked eye.

Success after ten years of research: Three intergrown compounds discovered The atomic structure of solid substances can often be analyzed quickly, easily and very precisely using X-rays. However, this requires that crystals of the corresponding substances are available. Chemist Oliver Oeckler of the University of Leipzig and his team are developing methods to make this possible even for very small crystals that are invisible to the naked eye.

Blast disease destroys between 10% and 35% of the world's rice harvest each year. A new discovery could lead to fungicides that block the pathogen, Magnaporthe oryzae, from entering the leaves. This photo of a healthy rice field was taken in Chengdu, China, in 2019. A fungus that plagues rice crops worldwide gains entry to plant cells in a way that leaves it vulnerable to simple chemical blockers, a discovery that could lead to new fungicides to reduce the substantial annual losses of rice and other valuable cereals.

A team of scientists from Austria and France has discovered a new abiotic pathway for the formation of peptide chains from amino acids - an important chemical step in the origin of life. The current study provides strong evidence that this crucial step for the emergence of life can indeed take place even in the very inhospitable conditions of space.

Writing in the Journal of Molecular Liquids , a team led by Professor Aravind Vijayaraghavan based in the National Graphene Institute (NGI) have produced 3-dimensional particles made of graphene, of many interesting shapes, using a variation of the vortex ring effect. The same effect is used to produce smoke rings and is responsible for keeping dandelion seeds flying.

Some "broken" nanomachines better sense their environment while others gain the ability to control their activity over time, researchers at Université de Montréal find. CONTENU - "Every act of creation," Picasso famously noted, "is first an act of destruction." Taking this concept literally, researchers in Canada have now discovered that "breaking" molecular nanomachines basic to life can create new ones that work even better.

Ribosomes are the nanomachines of the cell whose task is the correct synthesis of proteins. Researchers at the Heidelberg University Biochemistry Center are studying the emergence of these "protein factories", also known as ribosomes. Led by Ed Hurt, they have decoded the special role of a heretofore unexplored biogenesis factor in the maturation of precursor ribosomes.

Potential applications include industrial processes, drug discovery and optoelectronics Engineering novel molecules and materials with specific properties can yield significant advances for industrial processes, drug discovery and optoelectronics. However, the search for novel molecules and materials is comparable to looking for a needle in a haystack, since the number of molecules in chemical space is of the unimaginable order of 10 to the power of 60.

With a big assist from artificial intelligence and a heavy dose of human touch, Tim Cernak's lab at the University of Michigan made a discovery that dramatically speeds up the time-consuming chemical process of building molecules that will be tomorrow's medicines, agrichemicals or materials. The discovery, published in the Feb.
