Published Chemists devise a method for C-H activation of alcohols


Chemists have extended a powerful molecule-building method -- called C-H activation -- to the broad class of chemicals known as alcohols.
Published Researchers develop highly efficient and stable photoelectrode for water splitting using organic semiconductors


A recent study has unveiled a significant breakthrough in photoelectrode development.
Published Researchers use AI to find new magnetic materials without critical elements


A team of scientists developed a new machine learning model for discovering critical-element-free permanent magnet materials based on the predicted Curie temperature of new material combinations.
Published New ribozyme can make RNA molecules accessible for click chemistry in living cells


Important progress for RNA research: A team has discovered a new ribozyme that can label RNA molecules in living cells.
Published Efficient and mild: Recycling of used lithium-ion batteries


Lithium-ion batteries (LIBs) provide our portable devices like tablets and mobiles -- and increasingly also vehicles -- with power. As the share of volatile renewable energy needing electricity storage increases, more and more LIBs are needed, lithium prices rise, resources dwindle, and the amount of depleted batteries that contain toxic substances increases. Researchers introduce a novel approach for the recovery of lithium from used LIBs.
Published 3D-printed 'living material' could clean up contaminated water


A 'living material,' made of a natural polymer combined with genetically engineered bacteria, could offer a sustainable and eco-friendly solution to clean pollutants from water. Researchers developed their living material using a seaweed-based polymer and bacteria that have been programmed to produce an enzyme that transforms various organic pollutants into harmless compounds. In tests, heir material decontaminated water solutions tainted with a pollutant from textile manufacturing: indigo carmine, a blue dye that is used to color denim.
Published Better cybersecurity with new material


Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication.
Published Striking gold with molecular mystery solution for potential clean energy


Hydrogen spillover is exactly what it sounds like. Small metal nanoparticles anchored on a thermally stable oxide, like silica, comprise a major class of catalysts, which are substances used to accelerate chemical reactions without being consumed themselves. The catalytic reaction usually occurs on the reactive -- and expensive -- metal, but on some catalysts, hydrogen atom-like equivalents literally spill from the metal to the oxide. These hydrogen-on-oxide species are called 'hydrogen spillover.'
Published A system to keep cloud-based gamers in sync


A new technique can synchronize media streams from different networks to multiple devices with less than 10 milliseconds of delay. The technique was demonstrated on cloud gaming, but could also be applied in AR/VR applications.
Published New AI technology gives robot recognition skills a big lift


The day when robots can cook dinner, clear the kitchen table and empty the dishwasher is still a long way off. First, robots need to be able to recognize the many items of different sizes, shapes and brands in our homes. A team has now made a significant advance toward that technology with a robotic system that uses artificial intelligence to help robots better identify and remember objects.
Published Growing triple-decker hybrid crystals for lasers


By controlling the arrangement of multiple inorganic and organic layers within crystals using a novel technique, researchers have shown they can control the energy levels of electrons and holes (positive charge carriers) within a class of materials called perovskites. This tuning influences the materials' optoelectronic properties and their ability to emit light of specific energies, demonstrated by their ability to function as a source of lasers.
Published Breathe! The shape-shifting ball that supports mental health


A soft ball designed to support mental health by 'personifying' breath has been invented by a computer science student.
Published Analog and digital: The best of both worlds in one energy-efficient system


We live in an analog world of continuous information flow that is both processed and stored by our brains at the same time, but our devices process information digitally in the form of discrete binary code, breaking the information into little bits (or bites). Researchers have revealed a pioneering technology that combines the potential of continuous analog processing with the precision of digital devices. By seamlessly integrating ultra-thin, two-dimensional semiconductors with ferroelectric materials, the research unveils a novel way to improve energy efficiency and add new functionalities in computing. The new configuration merges traditional digital logic with brain-like analog operations.
Published New blood test for noncoding RNA significantly improves cancer detection


A lab is developing more accurate and powerful liquid biopsy technologies that take advantage of signals from RNA 'dark matter,' an understudied area of the genome.
Published Taking photoclick chemistry to the next level


Researchers have been able to substantially improve photoclick chemistry. They were able to boost the reactivity of the photoclick compound in the popular PQ-ERA reaction through strategic molecular substitution. They now report a superb photoreaction quantum yield, high reaction rates and notable oxygen tolerance.
Published Direct formation of sulfuric acid in the atmosphere


In the atmosphere, gaseous sulfuric acid can form particles that influence the physical properties of clouds. Thus, the formation of sulfuric acid in the gas phase directly affects the radiative forcing and Earth's climate. In addition to the known formation from sulfur dioxide, researchers have now been able to demonstrate through experiments that there is another formation pathway that has been speculated about for decades. Sulfuric acid in the atmosphere can also be formed directly by the oxidation of organic sulfur compounds. This new production pathway can be responsible for up to half of the gaseous sulfuric acid formation over the oceans and is thus of high importance for climate projections -- especially over the oceans of the Southern Hemisphere.
Published Energy storage in molecules


Molecular photoswitches that can both convert and store energy could be used to make solar energy harvesting more efficient. A team of researchers has used a quantum computing method to find a particularly efficient molecular structure for this purpose. Their procedure was based on a dataset of more than 400,000 molecules, which they screened to find the optimum molecular structure for solar energy storage materials.
Published Neural network helps design brand new proteins


A scientist combines attention neural networks with graph neural networks to better understand and design proteins. The approach couples the strengths of geometric deep learning with those of language models to predict existing protein properties and envision new proteins that nature has not yet devised. The model turns numbers, descriptions, tasks, and other elements into symbols for neural networks to use.
Published Overcoming the challenges to synthesising iron--sulfur proteins outside the glovebox


Iron--sulfur (Fe--S) proteins, essential to all life forms, are difficult to synthesise due to the complicated molecular machinery involved and sensitivity of Fe--S clusters to oxygen. In a new study, a team of researchers devised an innovative protocol for synthesising mature Fe--S proteins, by bringing together a recombinant sulfur assimilation (SUF) system and an oxygen-scavenging system, thereby, paving the way for new technologies and a better understanding of the evolution of life.
