Encyclopedia

Matter is any substance that has mass and takes up space by having volume. All everyday objects that we can touch are ultimately composed of atoms, which are made up of interacting subatomic particles, and in everyday as well as scientific usage, “matter” generally includes atoms and anything made up of them, and any particles (or combination of particles) that act as if they have both rest mass and volume. However it does not include massless particles such as photons, or other energy phenomena or waves such as light or sound.

Matter exists in various states (also known as phases). These include classical everyday phases such as solid, liquid, and gas – for example water exists as ice, liquid water, and gaseous steam – but other states are possible, including plasma, Bose–Einstein condensates, fermionic condensates, and quark–gluon plasma.

Usually atoms can be imagined as a nucleus of protons and neutrons, and a surrounding “cloud” of orbiting electrons which “take up space”. However this is only somewhat correct, because subatomic particles and their properties are governed by their quantum nature, which means they do not act as everyday objects appear to act – they can act like waves as well as particles and they do not have well-defined sizes or positions.

In the Standard Model of particle physics, matter is not a fundamental concept because the elementary constituents of atoms are quantum entities which do not have an inherent “size” or “volume” in any everyday sense of the word. Due to the exclusion principle and other fundamental interactions, some “point particles” known as fermions (quarks, leptons), and many composites and atoms, are effectively forced to keep a distance from other particles under everyday conditions; this creates the property of matter which appears to us as matter taking up space. — Wikipedia

Science

Chemistry is the scientific discipline involved with compounds composed of atoms, i.e. elements, and molecules, i.e. combinations of atoms: their composition, structure, properties, behavior and the changes they undergo during a reaction with other compounds. Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. — Wikipedia

Other multidisciplinary topics such as nanotechnology, chemical biology and materials chemistry are also featured.

  • Switching on prodrugs using radiotherapy
    by Jin Geng on June 10, 2021 at 12:00 am

    Nature Chemistry, Published online: 10 June 2021; doi:10.1038/s41557-021-00711-4Prodrugs offer one route to treat cancer, but they require activation once they have been delivered to the tumour. Now, a simultaneous chemo-radiotherapy strategy has been demonstrated in mice that uses gamma or X-ray irradiation to locally activate an anticancer prodrug.

    by Juan Hu on June 10, 2021 at 12:00 am

    Nature Chemistry, Published online: 10 June 2021; doi:10.1038/s41557-021-00708-zDroplet interface bilayer measurements have now shown that membranes formed from chiral phospholipid bilayers are enantioselectively permeable to chiral amino acids. The results show that membrane stereochemistry is necessary and sufficient to drive such enantioselective transport, presenting a new potential route to homochirality. These findings could also have implications for pharmacokinetics and drug design.

    by Pengwei Xu on June 10, 2021 at 12:00 am

    Nature Chemistry, Published online: 10 June 2021; doi:10.1038/s41557-021-00715-0The desymmetrization of easily accessible malonic esters represents an attractive approach towards the formation of chiral quaternary stereocentres, but is largely limited to enzymatic hydrolysis. Now, a zinc-catalysed asymmetric hydrosilylation reaction—that works with a broad scope of substrates—has been shown to reduce one of the esters to a primary alcohol with excellent enantiocontrol.

  • The gains from breaking symmetry

    Nature Chemistry, Published online: 10 June 2021; doi:10.1038/s41557-021-00731-0All-carbon quaternary centres are challenging targets in organic synthesis. Now, the development of a zinc-catalysed desymmetrization method enables the synthesis of chiral alcohols with all-carbon quaternary centres by the selective reduction of symmetrical α,α-disubstituted malonates.

    Nature Chemistry, Published online: 08 June 2021; doi:10.1038/s41557-021-00712-3Two phosphine-based reagents can be used to prepare aromatic acid chlorides in the presence of either primary or secondary amines. This approach enables the living polycondensation of aromatic amino acids under mild conditions and can be used to make block copolymers as well as helical aromatic amide foldamers.

  • Reduction of carbon monoxide through nitrogenase
    on June 10, 2021 at 5:55 pm

    Through the biological fixation of the element nitrogen by the enzyme nitrogenase, organisms gain access to molecular nitrogen (N2) in the Earth's atmosphere, which is essential for building cellular structures. In addition, a vanadium-dependent variant of nitrogenase can reduce the toxic gas carbon monoxide (CO) to hydrocarbons. These reductions of N2 and CO are among the most important processes in industrial chemistry, as they are used to produce both fertilizers and synthetic fuels. […]
