Chemistry articlesResearchers develop darkest manmade material
Researchers at Rensselaer Polytechnic Institute and Rice University have created the darkest material ever made by man.
Two aloof elements would bind under pressure, perhaps forming a superconductor, researchers say
It is the woeful truth: lithium (Li) and beryllium (Be) -- elements three and four, respectively, on the periodic table -- do not like each other.
New method enables design, production of extremely novel drugs
A new chemical synthesis method based on a catalyst worth many times the price of gold and providing a far more efficient and economical method than traditional ones for designing and manufacturing extremely novel pharmaceutical compounds is described by its University at Buffalo developers in a review article in the current issue of Nature.
Researchers can now determine when a human was born by looking into the eyes of the dead
Using the radiocarbon dating method and special proteins in the lens of the eye, researchers at the University of Copenhagen and Aarhus can now establish, with relatively high precision, when a person was born. This provides a useful tool for forensic scientists who can use it to establish the date of birth of an unidentified body and could also have further consequences for health science research.
Lost city pumps life-essential chemicals at rates unseen at typical black smokers
Hydrocarbons – molecules critical to life – are being generated by the simple interaction of seawater with the rocks under the Lost City hydrothermal vent field in the mid-Atlantic Ocean.
What goes down the drain, from ibuprofen to soaps, gets turned out to pasture via toxic sludge, researchers warn
What goes down the drain -- detergents, personal-care products and discarded and excreted medications -- may be out of sight and out of mind, but they are not, unfortunately, out of this world.
Squeezed crystals deliver more volts per jolt
A discovery by scientists at the Carnegie Institution has opened the door to a new generation of piezoelectric materials that can convert mechanical strain into electricity and vice versa, potentially cutting costs and boosting performance in myriad applications ranging from medical diagnostics to green energy technologies.
Magnetism loses under pressure
Scientists have discovered that the magnetic strength of magnetite—the most abundant magnetic mineral on Earth—declines drastically when put under pressure. Researchers from the Carnegie Institution's Geophysical Laboratory, together with colleagues at the Advanced Photon Source of Argonne National Laboratory, have found that when magnetite is subjected to pressures between 120,000 and 160,000 times atmospheric pressure its magnetic strength declines by half. They discovered that the change is due to what is called electron spin pairing.
Iowa state researcher studies how enzymes break down cellulose
Peter Reilly pointed to the framed journal covers decorating his office. Each of the six showed the swirling, twisting, complicated structure of an enzyme. Those bright and colorful illustrations are the work of his lab. And they're part of Reilly's work to understand how the structure of an enzyme influences its mechanism and its activity.
New process makes nanofibers in complex shapes and unlimited lengths
The continuous fabrication of complex, three-dimensional nanoscale structures and the ability to grow individual nanowires of unlimited length are now possible with a process developed by researchers at the University of Illinois.
Rounding up gases, nano style
Chemists unveil new process for capturing and storing gas. Potential spin-offs include improvements to greenhouse gas management and fuel cell development.
Argonne breakthrough may revolutionize ethylene production
A new environmentally friendly technology created by scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory may revolutionize the production of the world's most commonly produced organic compound, ethylene.
Lab on a chip mimics brain chemistry
Johns Hopkins researchers from the Whiting School of Engineering and the School of Medicine have devised a micro-scale tool — a lab on a chip — designed to mimic the chemical complexities of the brain.
Solar cell directly splits water for hydrogen
Plants trees and algae do it. Even some bacteria and moss do it, but scientists have had a difficult time developing methods to turn sunlight into useful fuel. Now, Penn State researchers have a proof-of-concept device that can split water and produce recoverable hydrogen.
Researchers probe a dna repair enzyme
U. of I. researchers have taken the first steps toward understanding how an enzyme repairs DNA.
Strengthening fluids with nanoparticles
Researchers at Rensselaer Polytechnic Institute have demonstrated that liquids embedded with nanoparticles show enhanced performance and stability when exposed to electric fields. The finding could lead to new types of miniature camera lenses, cell phone displays, and other microscale fluidic devices.
We are what we drink
University of Utah scientists developed a new crime-fighting tool by showing that human hair reveals the general location where a person drank water, helping police track past movements of criminal suspects or unidentified murder victims.
Catalysis discovery takes aim at nox emissions
A discovery in molecular chemistry may help remove a barrier to widespread use of diesel and other fuel-efficient "lean burn" vehicle engines. Researchers at the Department of Energy's Pacific Northwest National Laboratory have recorded the first observations of how certain catalyst materials used in emission control devices are constructed.
Structure of protein collagen seen at unprecedented level of detail
The structure and behavior of one of the most common proteins in our bodies has been resolved at a level of detail never before seen, thanks to new research performed at the Advanced Photon Source (APS) at the U.S. Department of Energy's Argonne National Laboratory.
Scientists identify proteins that help bacteria put up a fight
Scientists have identified the role of two proteins that contribute to disease-causing bacteria cells' versatility in resisting certain classes of antibiotics.
