Envelope for an artificial cell

(PhysOrg.com) -- Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain ...

Supercooled: Water doesn't have to freeze until -55 F

(PhysOrg.com) -- We drink water, bathe in it and we are made mostly of water, yet the common substance poses major mysteries. Now, University of Utah chemists may have solved one enigma by showing how cold water can get before ...

Carbyne is stronger than any known material

(Phys.org) —A paper on Arxiv presents a detailed look at the properties of carbyne, stronger than graphene and diamond, a true supermaterial. The paper is titled, "Carbyne from first principles: Chain of C atoms, a nanorod ...

Upsalite: Scientists make 'impossible material'... by accident

Researchers in Uppsala, Sweden accidentally left a reaction running over the weekend and ended up resolving a century-old chemistry problem. Their work has led to the development of a new material, dubbed Upsalite, with remarkable ...

Ordered planar polymers created for the first time

(PhysOrg.com) -- Scientists under the direction of ETH Zurich have created a minor sensation in synthetic chemistry. They succeeded for the first time in producing regularly ordered planar polymers that form a kind of "molecular ...

Mystery of car battery's current solved

(PhysOrg.com) -- Chemists have solved the 150 year-old mystery of what gives the lead-acid battery, found under the bonnet of most cars, its unique ability to deliver a surge of current.

A chemist is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties such as density and acidity. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, reaction rates, and other chemical properties.

Chemists use this knowledge to learn the composition, and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of subdisciplines of chemistry. Materials scientists and metallurgists share much of the same education and skills with chemists. The work of chemists is often related to the work of chemical engineers, which are primarily concerned with the proper design, construction and evaluation of the most cost-effective large-scale chemical plants and work closely with industrial chemists on the development of new processes and methods for the commercial-scale manufacture of chemicals and related products.
