Heterostructure crystals could light the way to optical circuits

Credit: Wiley-VCH It may be possible to reach new levels of miniaturization, speed, and data processing with optical quantum computers, which use light to carry information. For this, we need materials that can absorb and transmit photons. In the journal Angewandte Chemie, Chinese scientists have introduced a new strategy for constructing photonic heterostructure crystals with […]

Surprising discovery could change the way industry uses nickel

It is hard, yet malleable, magnetic at room temperature, and a relatively good conductor of electricity and heat. Most notably, nickel is highly corrosion resistant, which provides for a variety of uses by industry. […]

Researchers forecast failure in disordered materials

Credit: North Carolina State University Disordered materials—such as cellular foams, fiber and polymer networks—are popular in applications ranging from architecture to biomedical scaffolding. Predicting when and where these materials may fail could impact not only those materials currently in use, but also future designs. Researchers from North Carolina State University and the University of California […]

Lab produces simple fluorescent surfactants

Rice University chemists have produced an array of fluorescent surfactants for imaging, biomedical and manufacturing applications. Credit: Ashleigh Smith McWilliams/Rice University Laboratories use surfactants to separate things, and fluorescent dyes to see things. Rice University chemists have combined the two to simplify life for scientists everywhere. The Wiess School of Natural Sciences lab of chemist […]

Accelerating development of STT-MRAM

Credit: Tohoku University Researchers at the Center for Innovative Integrated Electronic Systems (CIES) at Tohoku University have successfully observed microscopic chemical bonding states in ultrathin MgO—an important determinant in STT-MRAM performance. The observation was carried out via an angle-resolved hard X-ray photoelectron spectroscopy (AR-HAXPES) in collaboration with Japan Synchrotron Radiation Research Institute (JASRI) at its […]

Polyoxometalate-based coordination frameworks for methane generation in photoreduction of carbon dioxide

POMCF for converting CO2 into CH4 in photoreduction system Credit: ©Science China Press Excessive CO2 discharge derived from the continuous burning of fossil fuels has caused global warming and environmental issues. Artificial conversion of excess CO2 into serviceable energy products is an important pathway to achieve sustainable development. Solar-driven photocatalytic reduction of CO2 to carbon-neutral […]

Eye-controlled soft lens paves way to soft human-machine interfaces

Schematic and photo of the soft lens system. Credit: Cai lab/Advanced Functional Materials A research team led by the University of California San Diego has developed a soft robotic lens whose movements are controlled by the eyes—blink twice and the lens zooms in and out; look left, right, up or down and the lens will […]

Setting the stage for fuel-efficient fertilizer

Credit: ACS Ammonia, the primary ingredient in nitrogen-based fertilizers, has helped feed the world since World War I. But making ammonia at an industrial scale takes a lot of energy, and it accounts for more than one percent of the world’s total energy-related carbon emissions. In nature, the enzyme nitrogenase produces ammonia in a much […]

New wood membrane provides sustainable alternative for water filtration

Inspired by the intricate system of water circulating in a tree, a team of researchers led by Princeton University, have figured out how to use a thin slice of wood as a membrane through which water […]

Researchers use machine learning technique to rapidly evaluate new transition metal compounds

Results from an artificial neural network (ANN) analysis may not be reliable for molecules that are too different from those on which the ANN was trained. The black clouds shown here cover transition metal complexes in the data set whose numeric representations are too distant from those of the training complexes to be considered reliable. […]
