Researchers have demonstrated how an experimental technique called optical forging can make graphene ultrastiff, increase its stiffness by several orders of magnitude.
Tiny nano-sized robots and vehicles that can navigate through blood vessels to reach the site of a disease could be used to deliver drugs to tumours that are otherwise difficult to treat.
Nature has developed excellent biolubricating systems but onnce biolubrication for instance of synovial joints of osteoarthritis patients breaks down, relief has to come from partially or fully synthetic biolubricants - such as polymeric micro- or nanoparticle-based lubricants - that replace the depleted natural substances. Researchers have now demonstrated that phytoglycogen nanoparticles - single-molecule highly branched polysaccharides extracted from sweet corn kernels - are a highly ...
As devices continue to be built on an increasingly small scale, scientists are looking toward developing ways to engineer materials at the atomic level. In a breakthrough that will contribute to this, researchers have developed a way to use a 'dry transfer technique' - a technique that uses no solvent - to position optical quality carbon nanotubes in a precise way.
Researchers have demonstrated the capability of the new X-ray method on a smart drug delivery nanoparticle and a polysoap nanostructure intended to capture crude oil spilled in the ocean.
