A Comprehensive Collaborative Agreement was signed by Prof. Dave Blank of NanoNextNL and Prof. Sukekatsu Ushioda of NIMS to pursue collaboration in the fields of mutual activity in nanotechnology area.
Materials in lithium ion battery electrodes expand and contract during charge and discharge. These volume changes drive particle fracture, which shortens battery lifetime. A group of ETH and PSI scientists have quantified this effect for the first time using high-resolution 3D movies recorded using x-ray tomography at the Swiss Light Source.
Graphene may command the lion's share of attention but it is not the only material generating buzz in the electronics world. Vanadium dioxide is one of the few known materials that acts like an insulator at low temperatures but like a metal at warmer temperatures starting around 67 degrees Celsius. This temperature-driven metal-insulator transition, the origin of which is still intensely debated, in principle can be induced by the application of an external electric field. That could yield faster and much more energy efficient electronic devices.
The combination of heat, chemotherapeutic drugs and an innovative delivery system based on nanotechnology may significantly improve the treatment of ovarian cancer while reducing side effects from toxic drugs, researchers at Oregon State University report in a new study.
A researcher from the University of Twente MESA+ Institute for Nanotechnology has developed an optical information carrier that can store information for extremely long periods of time, with each bit being written using etching techniques.
In lab experiments, Taxol, a chemotherapy drug used to treat ovarian cancer, was loaded onto a magneto-electric nanoparticle, and using an electric field the drug penetrated into the tumor cells completely destroying the tumor within 24 hours, while sparing normal ovarian cells.
Scientists report on a new method of rapidly identifying different molecular species under a microscope. Their technique of coherent Raman spectro-imaging with two laser frequency combs takes a big step towards the holy grail of real-time label-free biomolecular imaging.
Cell biologists and chemists from the University of Zurich reveal how viral DNA traffics in human cells. They have developed a new method to generate virus particles containing labeled viral DNA genomes. This allowed them to visualize, for the first time, single viral genomes in the cytoplasm and the nucleus by using fluorescence microscopy in regular or superresolution mode. The new findings enhance our understanding of how viral disease occurs, and how cells respond to infections.
Researchers have uncovered a novel effect that, in principle, offers a means of stabilizing quantum systems against decoherence. The discovery could represent a major step forward for quantum information processing.
Scientists from Stanford and Illinois have created a heat-resistant thermal emitter that could significantly improve solar cell efficiency. The novel component is designed to convert heat from the sun into infrared light that can be absorbed by solar cells to make electricity - a technology known as thermophotovoltaics.
The process can be carried out under any conditions, whatever the characteristics of the medium. This new click reaction can be used to connect two components (molecules, proteins, nanoparticles, etc.) in biological media as complex as human blood.
