Hard carbon nanofiber aerogel becomes superelastic

Conductive and compressible carbon aerogels are useful in a variety of applications. In recent decades, carbon aerogels have been widely explored by using graphitic carbons and soft carbons, which show advantages in superelasticity. ...

Green plastic production made easy

A one-step method enables scalable and more environmentally friendly production of plant-derived plastic monomers, paving the way towards the mass production of a sustainable alternative to petroleum-based materials.

A fail-safe mechanism for DNA repair

Single-molecule fluorescent measurements provide fresh insights into a process for keeping errors out of our genomes.

Nanopores make portable mass spectrometer for peptides a reality

University of Groningen scientists have developed nanopores to directly measure the mass of peptides. Although the resolution needs improvement, this proof of principle shows that a cheap and portable peptide mass spectrometer ...

RNA microchips

Ribonucleic acid (RNA) is, along with DNA and protein, one of the three primary biological macromolecules and was probably the first to arise in early life forms. In the "RNA world" hypothesis, RNA is able to support life ...

Researchers find value in unusual type of plant material

An ideal biorefinery would turn renewable crops into a variety of fuels and products with little waste. A significant challenge in realizing this vision is what to do with lignin, a fibrous and difficult-to-break-down material ...

Monomer

A monomer (from Greek mono "one" and meros "part") is an atom or a small molecule that may bind chemically to other monomers to form a polymer; the term "monomeric protein" may also be used to describe one of the proteins making up a multiprotein complex. The most common natural monomer is glucose, which is linked by glycosidic bonds into polymers such as cellulose and starch, and is over 76% of the mass of all plant matter. Most often the term monomer refers to the organic molecules which form synthetic polymers, such as, for example, vinyl chloride, which is used to produce the polymer polyvinyl chloride (PVC).
