Researchers have, for the first time, used a 'micropillar compression' technique to characterize the micro-scale strength of cement, allowing for the development of cement with desirable strength properties for civil engineering applications.
The new catalyst possesses the structure of nanofiber-based perovskite materials and exhibits excellent electrochemical performance, close that of today's precious metal catalysts, yet still inexpensive.
A recent study has presented a highly stable perovskite solar cells, using edged-selectively fluorine functionalized graphene nano-platelets. This breakthrough has gotten much attention as it is made out of fluorine, a low-cost alternative to gold.
Newly developed nanocomposite sensors are based on zinc and indium oxides, and their efficiency is maximized by green light illumination. The proposed device could be used to detect combustible, explosive, or poisonous substances in the atmosphere even at low concentrations.
Transitions occurring in nanoscale systems, such as a chemical reaction or the folding of a protein, are strongly affected by friction and thermal noise. Such transitions occur most frequently at intermediate friction, an effect known as Kramers turnover.
