Instead of having to use tons of crushing force and volcanic heat to forge diamonds, researchers at Case Western Reserve University have developed a way to cheaply make nanodiamonds on a lab bench at atmospheric pressure and near room temperature.
Johns Hopkins researchers used suction to learn that individual "molecular muscles" within cells respond to different types of force, a finding that may explain how cells "feel" the environment and appropriately adapt their shapes and activities. A computer model the researchers developed also lets them predict what a cell will do in response to altered levels of those "muscles," a common occurrence in a variety of cancers.
Flexible displays, cost-efficient solar cells for a new era of energy production, futuristic lighting at home - all require thin layers with specific properties. Scientists at the Leibniz Institute for New Materials are exploring new routes to such coatings in NanoSPEKT, a project funded by the German Federal Ministry of Education and Research (BMBF).
A South Korean joint industrial-academic research team has developed the technology to put forward the commercialization of nanowire that is only a few nanometers wide. It is expected to be applied in various fields such as semiconductors, high performance sensors, and biodevices.
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.
