matter : material substance that occupies space, has mass, and is composed predominantly of atoms consisting of protons, neutrons, and electrons, that constitutes the observable universe, and that is interconvertible with energy — Webster
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

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
Everything you’ve learned in school as “obvious” becomes less and less obvious as you begin to study the universe. For example, there are no solids in the universe. There’s not even a suggestion of a solid. There are no absolute continuums. There are no surfaces. There are no straight lines. — R. Buckminster Fuller

Nature Chemistry, Published online: 16 May 2022; doi:10.1038/s41557-022-00935-yMany bioactive compounds are trisubstituted macrocyclic alkenes, but use of current methods often results in poor yields and low stereoselectivity. Now, a ring-closing metathesis strategy has been developed that enables these compounds to be prepared efficiently and in either stereoisomeric form: an approach that may prove useful in the late stages of total syntheses, for skeletal editing and in drug discovery.

Nature Chemistry, Published online: 16 May 2022; doi:10.1038/s41557-022-00944-xPhytochromes regulate plant growth by sensing far-red light through the photoisomerization of their protein-bound chromophores. In the phytochrome Agp2, it has now been demonstrated that ultrafast proton-transfer occurs from the chromophore to a protein–water network before photoisomerization, inducing protein changes on the ultrafast timescale. These protein changes develop further on longer timescales, resulting […]

Nature Chemistry, Published online: 05 May 2022; doi:10.1038/s41557-022-00939-8Molecular photocatalysts for generating solar fuels such as hydrogen degrade over time, ceasing to function as intended. Now the mechanism by which a ruthenium–platinum-based hydrogen-evolving photocatalyst breaks down has been identified, leading to the development of a repair strategy that uses singlet oxygen to regenerate an inactivated bridging ligand.

Nature Chemistry, Published online: 05 May 2022; doi:10.1038/s41557-022-00943-yUnderstanding how surface structure affects catalyst selectivity is limited by the ability to synthesize atomically precise active-site ensembles. Now, by using intermetallic Pd–Zn, a series of well-defined multinuclear Pd–metal–Pd catalytic sites have been generated and studied, providing insights into their selectivity for the semi-hydrogenation of acetylene.

- Microbes can degrade the toughest PFASon May 23, 2022 at 8:28 pm
Engineers now report selective breakdown of a particularly stubborn class of PFAS called fluorinated carboxylic acids (FCAs) by common microorganisms. Under anaerobic conditions, a carbon-carbon double bond is crucial for the shattering the ultra-strong carbon-fluorine bond by microbial communities. The resulting products could be relayed to other microorganisms for defluorination under in aerobic conditions.

Scientists discover the enzymes responsible for the production of one of the most toxic and fast-acting neurotoxins associated with freshwater harmful algal blooms in lakes and ponds. The discovery revealed that guanitoxin-producing cyanobacteria are more prevalent than originally known in the United States, opening the possibility for new molecular diagnostic testing to better inform and protect the public from this natural freshwater toxin.
- PFAS chemicals do not last foreveron May 20, 2022 at 6:47 pm
Once dubbed 'forever chemicals,' per-and polyfluoroalkyl substances, or PFAS, might be in the market for a new nickname. Adding iodide to a water treatment reactor that uses ultraviolet (UV) light and sulfite destroys up to 90% of carbon-fluorine atoms in PFAS forever chemicals in just a few hours, reports a new study led by environmental engineers. The addition of iodide accelerates the speed of the reaction up to four times, saving energy and chemicals.
