Researchers in electrical and computer engineering at University of California, Santa Barbara have introduced and modeled an integrated circuit design scheme in which transistors and interconnects are monolithically patterned seamlessly on a sheet of graphene, a 2-dimensional plane of carbon atoms. The demonstration offers possibilities for ultra energy-efficient, flexible, and transparent electronics.
As researchers develop novel therapies based on inducing specific cells to do specific things, getting the right message to the right group of cells at the right time remains a major challenge. Now researchers at the Wellman Center for Photomedicine at Massachusetts General Hospital have developed a way to deliver a light signal to specific cells deep within the body.
Scientists used the powerful X-ray laser at the US Department of Energy's SLAC National Accelerator Laboratory to create movies detailing trillionths-of-a-second changes in the arrangement of copper atoms after an extreme shock. Movies like these will help researchers create new kinds of materials and test the strength of existing ones.
Researchers report the manufacture of a highly porous antireflection coatings with high TiO2-nanoparticle loading that combines excellent optical antireflectivity with efficient photocatalytic activity.
Graphene FET Flagship is an ambitious European project to move graphene out of academic labs and into society, where its applications are expected to have a strong technological and economic impact. Jani Kivioja, a Finnish scientist, is leading the industrial activities within the project. His group looks to solve scientific challenges in order to transform the converging Internet and communications industry.
A surprising enhancement was observed in this size regime when two different materials (silver and gold) were interfaced. Through theoretical modeling and quantum-mechanical calculations, quantum effects were determined to be responsible for this enhancement by creating a stronger condition for a "charge-transfer plasmon" resonance. The insight gained about this new mechanism may suggest general strategies for overcoming losses in plasmonic performance in the quantum size regime.
Researchers at the University of California, San Diego School of Medicine have discovered a way to effectively deliver staurosporine, a powerful anti-cancer compound that has vexed researchers for more than 30 years due to its instability in the blood and toxic nature in both healthy and cancerous cells.
Faster, smaller and more energy-efficient - that is what computers of the future should be like. A new phenomenon stands to make a major contribution in this direction: It needs 100,000 times less current than existing technologies, and the number of atoms needed for a data bit could diminish significantly.
