Artificial membranes mimicking those found in living organisms have many potential applications ranging from detecting bacterial contaminants in food to toxic pollution in the environment to dangerous diseases in people. Now a group of scientists has developed a way to create these delicate, ultra-thin constructs through a 'dry' process, by evaporating two commercial, off-the-shelf chemicals onto silicon surfaces.
Researchers have married two unconventional forms of carbon to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.
Scientists have studied the electronic characteristics of a newly synthesized molecule, composed of two forms of carbon: a fullerene (C60) and a nano-aggregate of diamond. This study reveals exceptional electronic properties for this molecule, given it conducts electrical power into one direction but not into the opposite sense.
Researchers demonstrate how graphene can be used to build a detector of long wavelength (far infrared or terahertz) light that is as sensitive as any existing detector, but far smaller and more than a million times faster.
A computer and data scientist has won a $250,000 National Science Foundation grant to develop a scalable data-mining framework that will help manufacturers quickly discover desired materials for building their products.
In an unprecedented view inside a working lithium-ion battery, researchers used a neutron beam to 'see' lithium flow as the battery charged and discharged. The study could one day help explain why rechargeable batteries lose capacity over time, and sometimes even catch fire.
Optical circuits use light instead of electricity, making them faster and more energy-efficient than electrical systems. Scientists have developed a first building-block for photonic 'transistors' that requires record-low energy to operate. The device is a big step forward in the development and implementation of optical circuits.
Scientists have developed a new screening method that makes it possible to study cell membrane proteins that bind drugs, such as cannabis and adrenaline, while reducing the consumption of precious samples by a billion times.
Researchers analyzed the properties of elemental bonds between semiconducting phosphorus atoms in 2-D sheets. Two-dimensional phosphorus is not theoretical; it was recently created through exfoliation from black phosphorus.
