From chemical graphs to structures
3D configurations of atoms dictate all materials properties. Quantitative predictions of accurate equilibrium structures, 3D coordinates of all atoms, from a chemical graph, a representation of the structural formula, is a challenging and computation.....»»
Researchers create a three-dimensional multi-focus laser for glass micro-sculpting
Glass materials are widely used in optical and optoelectronic devices due to their low cost and excellent mechanical and optical properties. Among them, glass concave/convex linear structures with feature sizes ranging from several micrometers to hun.....»»
How did the building blocks of life arrive on Earth? Zinc fingerprints in meteorites offer clues
Researchers have used the chemical fingerprints of zinc contained in meteorites to determine the origin of volatile elements on Earth. The results suggest that without 'unmelted' asteroids, there may not have been enough of these compounds on Earth f.....»»

Expansion technique to image nanoscale structures inside cells makes high-resolution imaging more accessible
A classical way to image nanoscale structures in cells is with high-powered, expensive super-resolution microscopes. As an alternative, MIT researchers have developed a way to expand tissue before imaging it—a technique that allows them to achieve.....»»
A look into "mirror molecules" may lead to new medicines
A University of Texas at Dallas chemist and his colleagues have developed a new chemical reaction that will allow researchers to synthesize selectively the left-handed or right-handed versions of "mirror molecules" found in nature and assess them for.....»»
Nissan dealership sues after toxic chemical fire forced 3-day closure
Conyers Nissan, located less than 3 miles from a fire that released dangerous levels of chlorine, is seeking class-action status to represent thousands of affected businesses......»»
Unveiling a new technique for preparing ionic liquid-based membranes for mixture separation
Separating mixtures into their constituent substances is essential in many fields. For example, mixture separation plays a key role in the petrochemical industry, as well as in chemical purification and synthesis plants. Moreover, separating mixtures.....»»
Making micelles more effective for dye and drug dispersion through well-defined core-shell structures
Micelles are spherical molecular structures usually formed by amphiphilic molecules with block structure, which contain both hydrophilic and hydrophobic parts. The hydrophobic tails of these molecules cluster together to form a core, while the hydrop.....»»
Reducing energy loss in metal nanostructures by altering geometrical dimensions
Researchers at City University of Hong Kong (CityUHK) have made a discovery that significantly reduces energy loss in metal nanostructures. By altering the geometrical dimensions of these structures, researchers have unlocked their full potential, pa.....»»
New insights into bubble interference could enhance electrode design
Industrial electrochemical processes that use electrodes to produce fuels and chemical products are hampered by the formation of bubbles that block parts of the electrode surface, reducing the area available for the active reaction. Such blockage red.....»»
Efficient way to hydrogenate nitrogen-containing aromatic compounds developed
Successful reduction of the chemical manufacturing industry's environmental impact relies on finding a greener way to make the chemical building blocks for common and massively consumed compounds......»»
AI and quantum mechanics team up to accelerate drug discovery
Drug discovery is much like working a jigsaw puzzle. The chemical compounds behind drug molecules must be shaped to fit with the proteins in our bodies to produce therapeutic effects. That requirement for a meticulous fit means the creation of new dr.....»»
The GALAH fourth data release provides vital data on one million stars in the Milky Way
For the past 10 years, Australia's ARC Center of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D) has been investigating star formation, chemical enrichment, migration, and mergers in the Milky Way with the Anglo-Australian Telescope (AA.....»»
Using AI to figure out the chemical composition of paints used in classical paintings
A team of chemists and AI researchers at CNR, Istituto di Scienze del Patrimonio Culturale, has developed an AI model capable of determining the chemical composition of the paints used to make classical paintings......»»
Fused molecules could serve as building blocks for safer lithium-ion batteries
By fusing together a pair of contorted molecular structures, Cornell researchers have created a porous crystal that can uptake lithium-ion electrolytes and transport them smoothly via one-dimensional nanochannels—a design that could lead to safer s.....»»
Scientists develop novel method for strengthening PVC products
Researchers have developed a way to make one type of plastic material more durable and less likely to shed dangerous microplastics. Their study has identified a secure way to attach chemical additives to polyvinyl chloride (PVC). The work is publishe.....»»
Developing novel chiral capsule tools for advanced optical technologies
Chirality is an essential property in biology; the molecular building blocks of some of the most important biological structures, including DNA and proteins, are chiral. When a molecule is said to be chiral, it means that it is distinguishable from i.....»»
Authoritarian populism has weakened democracy in Brazil, says study
The rise of authoritarian populism in Brazil has weakened structures that stabilize democracy—mirroring trends in wider global society and potentially making it harder for the country to strengthen its democracy in future, a new study reveals. The.....»»
