Use of nanoparticles in many applications, e.g. for catalysis, relies on the surface area of the particles. Now scientists show how originally spherical nucleus can transform into cube with high surface-to-volume ratio. These nanocubes are available to be used in practice, and may interest many designers of new materials. The research has recently been reported in ACS Nano.
A new method to develop complexly arranged tiny objects combined with microspheres has been discovered by a group of scientists at IBM Research Zurich and ETH Zurich. These tiny objects are only a few micrometres in size and are formed in a modular manner, allowing their design to be programmed so that every single component displays a wide variety of physical properties. This is followed by introducing the micro-objects into a solution through a very simple step after the fabrication process.
The world is run by catalysts. They clean up after cars, help make fertilizers, and could be the key to better hydrogen fuel. Now, a team of chemists, led by Xiaohu Xia from Michigan Technological University, has found a better way to make metal catalysts.
A paperlike battery electrode developed by a Kansas State University engineer may improve tools for space exploration or unmanned aerial vehicles.
Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor in Engineering and founding chair of the Department of Materials Science and NanoEngineering, has been chosen to receive two major honors in his field: the 2016 Lifetime Achievement Award in Nanotechnology from the Houston Technology Center and the 2016 NANOSMAT Prize.
Scientists have devised a triple-stage "cluster bomb" system for delivering the chemotherapy drug cisplatin, via tiny nanoparticles designed to break up when they reach a tumor.
EPFL researchers have shown that a law of physics having to do with electron transport at nanoscale can also be analogously applied to the ion transport. This discovery provides insight into a key aspect of how ion channels function within our living cells.
Being able to detect early on whether a cancer therapy is working for a patient can influence the course of treatment and improve outcomes and quality of life. However, conventional detection methods – such as PET scans, CT and MRI – usually cannot detect whether a tumor is shrinking until a patient has received multiple cycles of therapy. A new technique developed in pre-clinical models by investigators at Brigham and Women’s Hospital (BWH) offers a new approach and a read out on the effectiveness of chemotherapy in as few as eight hours after treatment.
When it comes to the various nanowidgets scientists are developing, nanotubes are especially intriguing. That’s because hollow tubes that have diameters of only a few billionths of a meter have the potential to be incredibly useful, from delivering cancer-fighting drugs inside cells to desalinating seawater.
A team of researchers from Stony Brook University, SUNY Polytechnic Institute, and George Washington School of Medicine have demonstrated a pioneering method for the rapid visualization and identification of engineered nanoparticles in tissue. The research, detailed in a paper published in Microscopy Research and Technique, is a cost-effective hyperspectral imaging method for nanomaterial analysis that may shed light on nanomaterials’ potential health impacts.
