Early-Earth cells modeled to show how first life forms might have packaged RNA
(Phys.org)—Researchers at Penn State University have developed a chemical model that mimics a possible step in the formation of cellular life on Earth four-billion years ago. Using large "macromolecules" ...
Researchers develop new technique for heterogenizing homogenous nano catalysts
(Phys.org)—Catalysts are substances that speed up the rates of chemical reactions without themselves being chemically changed. Industrial catalysts come in two main types - heterogeneous, in which the catalyst ...
Thermoelectric material is world's best at converting heat waste to electricity
Northwestern University scientists have developed a thermoelectric material that is the best in the world at converting waste heat to electricity. This is very good news once you realize nearly two-thirds of energy input ...
Molecule reorganises itself for new functions
(Phys.org) -- The discovery of a synthetic molecule, made up of 60 simple components that are able to reorganise themselves to produce new functions, will lead to better understanding of nature's processes.
Graphene's behavior depends on where it sits
When you look at a gift-wrapped present, the basic properties of the wrapping paper say, its colors and texture are not generally changed by the nature of the gift inside.
Researchers explain how dye-based nanotubes can help harvest light's energy
Companies that make commercial solar cells are happy if they can achieve 20 percent efficiency when converting sunlight to electricity; an improvement of even 1 percent is seen as major progress. But nature, ...
New 3D printing process could lead to DIY drugstores
(Phys.org) -- A new 3D printing process developed at the University of Glasgow could revolutionise the way scientists, doctors and even the general public create chemical products.
Scientists discover a surprising new way that protons can move among molecules
When a proton the bare nucleus of a hydrogen atom transfers from one molecule to another, or moves within a molecule, the result is a hydrogen bond, in which the proton and another atom like ...
Scientists develop new class of small molecules through innovative chemistry
Inspired by natural products, scientists on the Florida campus of the Scripps Research Institute have created a new class of small molecules with the potential to serve as a rich foundation for drug discovery.
Research pinpoints role of 'helper' atoms in oxygen release
(Phys.org) —Experiments at the Department of Energy's SLAC National Accelerator Laboratory solve a long-standing mystery in the role calcium atoms serve in a chemical reaction that releases oxygen into ...
New star-shaped molecule breakthrough
(Phys.org) —Scientists at The University of Manchester have generated a new star-shaped molecule made up of interlocking rings, which is the most complex of its kind ever created.
Continuing Bragg legacy of structure determination
Over 100 years since the Nobel Prize-winning father and son team Sir William and Sir Lawrence Bragg pioneered the use of X-rays to determine crystal structure, University of Adelaide researchers have made significant new ...
A new synthetic amino acid for an emerging class of drugs
Swiss scientists have developed a new amino acid that can be used to modify the 3-D structure of therapeutic peptides. Insertion of the amino acid into bioactive peptides enhanced their binding affinity up ...
Mimicking natural evolution with 'promiscuous reactions' to improve the diversity of drugs
A revolutionary new scientific method developed at the University of Leeds will improve the diversity of 'biologically active molecules', such as antibiotics and anti-cancer agents.
