By harnessing an electropolymerization process to produce aligned arrays of polymer nanofibers, researchers have developed a thermal interface material able to conduct heat 20 times better than the original polymer. The material can operate at up to 200 degrees Celsius.
New reveals that solar cell efficiency is based upon a delicate balance between the size and purity of the interior layers, or domains. These findings may lead to better designs and improved performance in organic solar cells.
Scientists at the Center for Nanotechnology and Nanotoxicology at Harvard School of Public Health have discovered a fast, simple, and inexpensive method to measure the effective density of engineered nanoparticles in physiological fluids, thereby making it possible to accurately determine the amount of nanomaterials that come into contact with cells and tissue in culture.
A new analysis accurately describes the behavior of silicon photon microresonators in the nonlinear regime, where the amount of light exiting the system is not directly proportional to the amount of light entering it.
Latest research finds that the trailblazing perovskite material used in solar cells can double up as a laser, strongly suggesting the astonishing efficiency levels already achieved in these cells is only part of the journey.
Umea University in Sweden will be a national resource for advanced electron microscopy thanks to a contribution of SEK 57 million. Scientists across the country will be able to use the techniques for research.
An application highly desired by the semiconductor industry is graphene's potential role as a replacement for silicon as a substrate in microchips. Thanks to an innovative technique for applying dielectrics (insulating layers) onto graphene, that goal is a bit closer to reality.
Researchers describe a development method using columnar thin films that is quick, provides a high level of detail and resolution, and yields consistent results on prints recovered from many types of nonporous surfaces.
Engineers have demonstrated that it is possible to generate nanostructures from silk in an environmentally friendly process that uses water as a developing agent and standard fabrication techniques. This approach provides a green alternative to the toxic materials commonly used in nanofabrication while delivering fabrication quality comparable to conventional synthetic polymers.
