Scientists reveal dynamic silver crystallization by in-situ SEM

Different structured materials have different properties and applications. Disclosing the formation mechanism of material structures may help develop routes for the rational synthesis. However, how the materials structures ...

A tale of shepherds and helices

The relief "Adoration of the Shepherds" by the Italian sculptor Giuseppe Torretti is disfigured by lumpy salt crystals. Now, a research group at the Max Planck Institute for Solid State Research in Stuttgart has established ...

Researchers identify breaking point of conducting material

An improved method to predict the temperature when plastics change from supple to brittle, which could potentially accelerate future development of flexible electronics, was developed by Penn State College of Engineering ...

Examining ice giants with NASA's Webb telescope

Far-flung Uranus and Neptune—the ice giants of our solar system—are as mysterious as they are distant. Soon after its launch in 2021, NASA's James Webb Space Telescope will change that by unlocking secrets of the atmospheres ...

Scientists propose new properties in hollow multishell structure

The Chinese puzzle ball is an ornate decorative artwork consisting of several concentric shells that move independently of each other. In the recent decade, Chinese scientists provided a universal method for the fabrication ...

Unique organic light-emitting molecular emitters

A team including researchers from Osaka University has produced a new molecular emitter for organic light-emitting diodes (OLEDs). Using rational chemical design with U-shaped synthetic building blocks, the scientists were ...

Solving fossil mystery could aid Mars life quest

Research which suggests that structures previously thought to be fossils may, in fact, be mineral deposits could save future Mars missions valuable time and resources.

Chemists use light to build biologically active compounds

Some of the most biologically active molecules, including synthetic drugs, contain a central, nitrogen-containing chemical structure called an isoquinuclidine. This core has a three-dimensional shape which means it has the ...

Chemical structure

A chemical structure includes molecular geometry, electronic structure and crystal structure of a chemical compound. Molecular geometry refers to the spatial arrangement of atoms in a molecule and the chemical bonds that hold the atoms together. Molecular geometry can range from the very simple, such as diatomic oxygen or nitrogen molecules, to the very complex, such as protein or DNA molecules. Molecular geometry can be roughly represented using a structural formula. Electronic structure describes the occupation of a compound's molecular orbitals.
