Using X-ray photoelectron spectroscopy - a technique used to examine the surface chemistry of a solid material - researchers have begun to understand the operating principles and sensing mechanisms behind promising nanocomposite thin film materials.
Scientists are investigating the use of nanoparticles as a way to disinfect wounds. It could prove to be much more effective than existing techniques because the particles would be tiny enough to enter the skin via hair follicles, ensuring much better penetration of the area affected by surgery.
Chemists have developed a novel type of firefighting foam based on inorganic silica nanoparticles. The new foam beats existing analogues in fire extinguishing capacity, thermal and mechanical stability and biocompatibility.
Metal-organic frameworks are a new type of materials with nanoscale pores. Bioscience engineers have developed an alternative method that produces these materials in the form of very thin films, so that they can easily be used for high-tech applications such as microchips.
A new material that is both highly transparent and electrically conductive could make large screen displays, smart windows and even touch screens and solar cells more affordable and efficient, according to materials scientists and engineers who have discovered just such a material.
Combining photo-responsive fibers with thermo-responsive gels, researchers have modeled a new hybrid material that could reconfigure itself multiple times into different shapes when exposed to light and heat, allowing for the creation of devices that not only adapt to their environment, but also display distinctly different behavior in the presence of different stimuli.
To isolate the contribution of water to the vibrational fluctuations that occur between DNA, bulk water, and the charged biomolecular interface between the two, researchers have performed two-dimensional spectroscopic analyses on double-stranded DNA helices at different hydration levels.
