Published Shedding light on unique conduction mechanisms in a new type of perovskite oxide



The remarkable proton and oxide-ion (dual-ion) conductivities of hexagonal perovskite-related oxide Ba7Nb3.8Mo1.2O20.1 are promising for next-generation electrochemical devices. The unique ion-transport mechanisms they unveiled will hopefully pave the way for better dual-ion conductors, which could play an essential role in tomorrow's clean energy technologies.
Published Pushing the boundaries of eco-friendly chemical production



A team of pioneering researchers has made a significant leap forward in the complex world of molecular chemistry. Their focus? Azaarenes, unique molecular puzzle pieces crucial to many everyday products, from eco-friendly agrochemicals to essential medicines. The team developed an innovative way to modify these molecules using light-powered enzymes -- a groundbreaking discovery that holds promise for new industrially relevant chemical reactions and sustainable energy solutions.
Published Engineering bacteria to biosynthesize intricate protein complexes



Protein cages found in nature within microbes help weather its contents from the harsh intracellular environment -- an observation with many bioengineering applications. Researchers recently developed an innovative bioengineering approach using genetically modified bacteria; these bacteria can incorporate protein cages around protein crystals. This in-cell biosynthesis method efficiently produces highly customized protein complexes, which could find applications as advanced solid catalysts and functionalized nanomaterials.
Published Water splitting reaction for green hydrogen gas production improved



Electrochemical catalysts used in water splitting often show poor performance due to low electrical conductance of (oxy)hydroxide species produced in situ. To overcome this challenge, researchers have now designed an electrode with Schottky Junction formed at the interface of metallic Ni-W5N4 and semiconducting NiFeOOH. The proposed electrode shows excellent catalytic activity and can facilitate industrial seawater splitting continuously for 10 days.
Published Some of today's earthquakes may be aftershocks from quakes in the 1800s



In the 1800s, some of the strongest earthquakes in recorded U.S. history struck North America's continental interior. Almost two centuries later, the central and eastern United States may still be experiencing aftershocks from those events, a new study finds.
Published AI programs spat out known data and hardly learned specific chemical interactions when predicting drug potency



Artificial intelligence (AI) is on the rise. Until now, AI applications generally have 'black box' character: How AI arrives at its results remains hidden. A cheminformatics scientist has now developed a method that reveals how certain AI applications work in pharmaceutical research. The results are unexpected: the AI programs largely remembered known data and hardly learned specific chemical interactions when predicting drug potency.
Published Solar-powered device produces clean water and clean fuel at the same time



A floating, solar-powered device that can turn contaminated water or seawater into clean hydrogen fuel and purified water, anywhere in the world, has been developed by researchers.
Published How to use AI for discovery -- without leading science astray



In the same way that chatbots sometimes 'hallucinate,' or make things up, machine learning models designed for scientific applications can sometimes present misleading or downright false results. Researchers now present a new statistical technique for safely using AI predictions to test scientific hypotheses.
Published Chemists image basic blocks of synthetic polymers



Researchers have developed a new method to image polymerization catalysis reactions one monomer at a time.
Published Scientists use quantum biology, AI to sharpen genome editing tool



Scientists used their expertise in quantum biology, artificial intelligence and bioengineering to improve how CRISPR Cas9 genome editing tools work on organisms like microbes that can be modified to produce renewable fuels and chemicals.
Published Liquid metals shake up century-old chemical engineering processes



Liquid metals could be the long-awaited solution to 'greening' the chemical industry, according to researchers who tested a new technique they hope can replace energy-intensive chemical engineering processes harking back to the early 20th century.
Published New dates for landslides reveal past Seattle fault earthquakes



New maps of more than 1,000 deep-seated landslides in the Puget Lowlands of Washington State provide evidence of the last major earthquake along the Seattle Fault about 1,100 years ago -- and may also hold traces of older earthquakes along the fault.
Published Photo battery achieves competitive voltage



Researchers have developed a monolithically integrated photo battery using organic materials. The photo battery achieves an unprecedented high discharge potential of 3.6 volts. The system is capable of powering miniature devices.
Published Charged 'molecular beasts' the basis for new compounds



Mass spectrometers are high-tech machines that play an important role in our society. They are highly sensitive analytical instruments that are indispensable in areas such as medical diagnostics, food quality control and the detection of hazardous chemical substances. A research group is working to modify mass spectrometers so that they can be used for a completely different purpose: the chemical synthesis of new molecules.
Published Self-powered microbial fuel cell biosensor for monitoring organic freshwater pollution



Biodegradable waste from plant and animal sources released into freshwater ecosystems is a significant environmental concern. Nonetheless, current methods for assessing water quality seem more or less impractical due to their complexity and high costs. In a promising development, a team of researchers has successfully constructed a self-sustaining and buoyant biosensor using inexpensive carbon-based materials for monitoring water quality at the inlets of freshwater lakes and rivers.
Published Hebrew prayer book fills gap in Italian earthquake history



The chance discovery of a note written in a 15th century Hebrew prayer book fills an important gap in the historical Italian earthquake record, offering a brief glimpse of a previously unknown earthquake affecting the Marche region in the central Apennines.
Published Chemists make breakthrough in drug discovery chemistry



Chemists offer two new methods to develop a way to easily replace a carbon atom with a nitrogen atom in a molecule. The findings could make it easier to develop new drugs.
Published The remains of an ancient planet lie deep within Earth



The remnants of an ancient planet that collided with Earth to form the Moon lie deep within the earth, according to a new model.
Published Breakthrough discovery sheds light on heart and muscle health



The human heart, often described as the body's engine, is a remarkable organ that tirelessly beats to keep us alive. At the core of this vital organ, intricate processes occur when it contracts, where thick and thin protein-filaments interact within the sarcomere, the fundamental building block of both skeletal and heart muscle cells. Any alterations in thick filament proteins can have severe consequences for our health, leading to conditions such as hypertrophic cardiomyopathy and various other heart and muscle diseases.
Published New Nijmegen method reveals hidden genetic variations



Many hidden genetic variations can be detected with Chameleolyser, a new method. The information is already yielding new patient diagnoses and may also lead to the discovery of as yet unknown disease genes.
