STOCKHOLM (Reuters) -Scientists Moungi Bawendi, Louis Brus and Aleksey Ekimov won the 2023 Nobel Prize in Chemistry for their discovery of tiny clusters of atoms known as quantum dots, widely used ...
The scientists say some of these small protein, or peptide, molecules they have identified have bacteria-fighting powers that may inspire new drugs to fight infections in humans.
Meteorites are often studied as part of cosmochemistry. Cosmochemistry (from Ancient Greek κόσμος (kósmos) ' universe ' and χημεία (khēmeía) ' chemistry ') or chemical cosmology is the study of the chemical composition of matter in the universe and the processes that led to those compositions. [1]
Semicrystalline: A solid state in complex organic chemistry where molecules are packed in a regular order but have substantial local disorder. Different structural phases of polymorphic materials are considered to be different states of matter in the Landau theory. For an example, see Ice § Phases. Liquid: A mostly non-compressible fluid. Able ...
Chemistry is the scientific study of the properties and behavior of matter.It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
The study of molecules by molecular physics and theoretical chemistry is largely based on quantum mechanics and is essential for the understanding of the chemical bond. The simplest of molecules is the hydrogen molecule-ion , H 2 + , and the simplest of all the chemical bonds is the one-electron bond .
Stellar molecules are molecules that exist or form in stars. Such formations can take place when the temperature is low enough for molecules to form – typically around 6,000 K (5,730 °C; 10,340 °F) or cooler. [1] Otherwise the stellar matter is restricted to atoms and ions in the forms of gas or – at very high temperatures – plasma.
Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over astronomical distances.
