A finding by an intercontinental group of researchers from Princeton University, the Georgia Institute of Technology and Humboldt University in Berlin directs the way to more extensive application of an advanced technology commonly known as organic electronics.
Germanium, considered to be a more efficient elemental semiconductor than silicon, was the material of choice in the early history of electronic devices. Eventually, the high cost of developing germanium crystals concealed its efficiency, and silicon thus captured the field.
In several regions of the developing world, people have plentiful heat from the sun during the day, but majority of the cooking happens later in the evening when the sun sets, using fuel - such as wood, dung, or brush - that is gathered with substantial time and effort.
There are numerous technologies with potential under development that can decrease energy consumption or capture carbon in fields including biotech, nanotechnology, materials science, computer science, and more. Not all will prove viable, but with some funding and nurturing, many could help solve Earth’s grand challenge.
Excess hydrogen is capable of causing problems in a wide range of industries. It can corrode electronics, semiconductors, and nuclear fuel sitting in storage. It also comprises of an explosion hazard. To remove this extra hydrogen, it is possible for chemists to use an organic compound known as a hydrogen getter that chemically binds to a number of hydrogen atoms.
In the future, 3D laser melting process can be adopted for manufacturing innovative designer alloys used in aerospace applications—a process known as additive manufacturing, or AM.
In generators, motors, and other similar electric machines, the electrical current that powers them produces magnetic fields that magnetize a number of the metallic components.
High-efficiency electric motors with custom-made speed-torques, defined by their magnetic components, are vital for sustainable, effective electric automobile drive concepts.
Materials can change their shape when hit by a powerful shock wave – a property called plasticity – yet they keep their lattice-like atomic structure. Scientists have now used the X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory to observe, for the first time, how a material’s atomic structure gets deformed when shocked by pressures almost as extreme as the ones at the center of the Earth.
A new study from the University of Michigan Life Sciences Institute is constructing a bridge from nature's chemistry to greener, more efficient artificial chemistry.
