Recently, in situ observations of mechanochemical reactions have been achieved by X-ray diffraction and Raman spectroscopy. Solid-state reactions can be directly tracked, revealing phase transitions and other material transformations during synthesis in a ball mill jar.
Scientists have developed a calculation method for identifying optimal nanostructures to either maximize or minimize the thermal resistance of target materials. This method reduced the amount of calculation by more than 90% compared to conventional methods.
The anticaking agent E551 silicon dioxide, or silica, has been used widely in the food industry over the past 50 years, and was long thought to be quite safe. Now, however, researchers have discovered that these nanoparticles can affect the immune system of the digestive tract.
In an effort to understand how single cells heal, mechanical engineers have developed a microscopic guillotine that efficiently cuts cells in two. Learning more about single-cell wound repair could lead to self-healing materials and machines.
Scientists report on strides made in the development of a strategy to improve the immune system's detection of cancer proteins by using 'sticky' nanoparticles that are called 'antigen-capturing nanoparticles'.
A new study sheds light on the properties of nanostructures capable of ensuring an effective integration with nerve cells, an essential quality for developing innovative systems targeting the repair of neuronal damages.
