Researchers at Kyushu University have formulated a new approach that could be the foundation of a whole new range of electronic devices possessing exceptionally tunable properties. Using this approach, the team was able to extensively vary the efficiency and emission color of organic light-emitting diodes based on exciplexes merely by modifying the distance by a few nanometers between key molecules in the devices.
Solar cells that are extremely lightweight, flexible, and thin can be placed on any kind of surface or material, which may include smartphones, helium balloons or even a sheet of paper.
A quick, cheap and highly efficient method for producing a water-purifying chemical has been developed by researchers at Cardiff University.
Chemistry is like a toolbox. To synthesize pharmaceuticals, plastics or dyes, chemists reach for various reagents and methods like craftspeople reach for their tools. Scientists from the Max-Planck-Institut für Kohlenforschung in Mülheim an der Ruhr have now presented a new chemical tool that facilitates an important synthesis step, hydrocyanation, in a safer manner than the conventional method.
Gather your patience and put the old “a watched pot never boils” saying to the test. The experience might rival watching paint dry, but of course the water will eventually begin to boil. When it does, you’ll see a flurry of bubbles form and quickly rise to the surface of the water. Once it kicks in, it builds at a furious pace and quickly creates a roiling cauldron on your stovetop. Time to add the pasta.
Lithium-ion batteries gained popularity in the 1990s, and have lead to the replacement of nickel-metal hydride batteries. Today Li-ion batteries power numerous electronic gadgets, such as mobile, laptops, and tablets.
A new method of developing polarizers, devices which rotate the plane of light, has been developed which mimics the way shrimps polarize light. Whilst humans use polarizers in sunglasses and DVD players shrimp have been using them to communicate without having to worry about any prey eavesdropping on their conversation.
The promise of high conversion efficiency with lower cost has put perovskite solar cells under intense research in the field of photovoltaics.
The research group of Professor Hideo Ohno and Associate Professor Shunsuke Fukami of Tohoku University has studied the control of magnetization using a current applied to heterostructures comprising an antiferromagnet.
When exposed to changes in temperature the shape of polymers often visibly change. New research, led by chemical engineering professor Mitch Anthamatten at the University of Rochester, has led to the development of a material capable of changing shape when exposed to body heat alone. This research paves the way for unique medical and other applications.
