Milling electronic waste into nanoscale particles allows polymers, oxides and metals to be separated for recycling into new products. The process takes advantage of changes to the materials' properties in very cold conditions.
A proof-of-concept molecular modeling study that analyzes the efficiency of amine solutions in capturing carbon dioxide is the first step toward the design of cheaper, more efficient amine chemicals for capturing carbon dioxide -- and reducing harmful CO2 emissions -- in industrial installations.
Researchers have found a way to mimic the way cells in living organisms 'talk' to the world around them by creating a world-first synthetic receptor which can respond to chemical signals just like its natural equivalent.
Researchers have developed a new method of controlling biology at the cellular level using light. The tool -- called a photocleavable protein -- breaks into two pieces when exposed to light, allowing scientists to study and manipulate activity inside cells in new and different ways.
Scientists have succeeded in ‘filming’ inter-molecular chemical reactions – using the electron beam of a transmission electron microscope (TEM) as a stop-frame imaging tool. They have also discovered that the electron beam can be simultaneously tuned to stimulate specific chemical reactions by using it as a source of energy as well as an imaging tool.
Researchers have developed an original method -- soft-confinement pattern-induced nanoparticle segregation (SCPINS) -- to fabricate polymer nanocomposite thin films with well-controlled nanoparticle organization on a submicron scale. This new method uniquely controls the organization of any kind of nanoparticles into patterns in those films, which may be useful for applications involving sensors, nanowire circuitry or diffraction gratings, with proper subsequent processing steps like thermal or UV sintering that are likely required.
A team of chemists has created self-assembled, three-dimensional DNA crystals that can bind a separate, dye-bearing strand -- a breakthrough that enhances the functionality of these tiny building blocks.
Scientists discover that the iron sulfide battery material undergoes significant changes in its microstructure and chemical composition as sodium ions enter and leave the material during the first discharge/charge cycle, leading to an initial loss in battery capacity.
For the first time ever, researchers have managed to functionally characterize the three-dimensional interaction between red-light receptors and enzymatic effectors. The results have implications for optogenetics.
Mercury is very toxic and can cause long-term health damage, but removing it from water is challenging. To address this growing problem scientists have created a sponge that can absorb mercury from a polluted water source within seconds.
Researchers have developed the next step in microbial fuel cells (MFCs) with the first micro-scale self-sustaining cell, which generated power for 13 straight days through symbiotic interactions of two types of bacteria.
A new bioinformatics advance reveals the power of 'big data' genome technology to help us make better use of nature's inventions: a team of researchers has created a tool that searches through microbial genomes, identifying clusters of genes that indicate an organism's ability to synthesize therapeutically promising molecules.
