Scientists from Brandeis University and the University of Pittsburgh show how identical cells differentiate
Alan Turing's accomplishments in computer science are well known, but lesser known is his impact on biology and chemistry. In his only paper on biology, Turing proposed a theory of morphogenesis, or how identical copies of a single cell differentiate, for example, into an organism with arms ...
Team creates LEDs, photovoltaic cells, and light detectors using novel 1-molecule-thick material
A team of MIT researchers has used a novel material that's just a few atoms thick to create devices that can harness or emit light. This proof-of-concept could lead to ultrathin, lightweight, and flexible photovoltaic cells, light emitting diodes (LEDs), and other optoelectronic devices, they ...
Researchers describe microbe that 'eats' electricity
There have been plenty of fad diets that captured the public's imagination over the years, but Harvard scientists have identified what may be the strangest of them all – sunlight and electricity. Led by Peter Girguis, the John L. Loeb Associate Professor of the Natural Sciences, and Arpita ...
Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more ...
Now online: the most comprehensive calendar of events for the chemical, life science and analytics industries
Trade fairs, congresses, conferences, seminars and webinars – companies and organisations in chemistry, life sciences and analytics host a wide spectrum of events. But where do you find training opportunities for your profession? Which conferences can keep you up-to-date with developments in ...
A bright future for optoelectronics
A special type of diode made from a crystalline material whose layers are just three atoms thick has been successfully realized for the first time. The superior properties of such ultra-thin crystals open up previously unimagined possibilities for solar cells, photodiodes and light-emitting ...
Electronic disruption prods Mott insulator's conversion to metallic state
In a relatively recently discovered class of materials, known as spin-orbit Mott insulators, theorists have predicted the emergence of new properties at points just beyond the insulating state, when electronic manipulation can transform these compounds into conducting metals. A better ...
A team of University of Notre Dame researchers led by Mayland Chang and Shahriar Mobashery have discovered a new class of antibiotics to fight bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) and other drug-resistant bacteria that threaten public health. Their research is ...
Using an inexpensive inkjet printer, University of Utah electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls electrical conductivity within such microstructures, could be used to rapidly fabricate superfast ...
Ultrathin layers made of Tungsten and Selenium have been created at the Vienna University of Technology. Experiments show that they may be used as flexible, semi-transparent solar cells.
It does not get any thinner than this: The novel material graphene consists of only one atomic layer of carbon atoms and exhibits very special electronic properties. As it turns out, there are other materials too, which can open up intriguing new technological possibilities if they are ...
