(Nanowerk News) Using state-of-the-art microscopy and simulation techniques, an international research team systematically observed how iron atoms alter the structure of grain boundaries in titanium.

Results indicate that grain boundary strength and motion, accommodated by either shear-coupled migration (SCM) or grain boundary sliding (GBS), strongly varies with pressure resulting in grain ...

Using state-of-the-art microscopy and simulation techniques, an international research team systematically observed how iron atoms alter the structure of grain boundaries in titanium. They were in for ...

Cobalt-free LiNiO2 (LNO) is considered a promising cathode for its high energy density and cost-effectiveness. However, its ...

Most materials, especially metals and ceramics, are crystals. Their atoms are arranged in three-dimensional lattices that repeat the same exact pattern, over and over again. But there's a well-known ...

Controlling boron concentration at grain boundaries in platinum nanocatalysts prevents structural failure and preserves catalytic performance under prolonged high temperature conditions. (Nanowerk ...

Materials are often considered to be one phase, but many engineering materials contain two or more phases, improving their properties and performance. These two-phase materials have inclusions, called ...

Researchers from City University of Hong Kong (CityUHK), in collaboration with experts from local and overseas universities, have reshaped scientists’ fundamental understanding of the kinetic ...

The goal of increasing efficiency, stability, and lowering production costs in photovoltaic (PV) technology has pushed research into a new frontier: the nanoscale. It is now unequivocally established ...

A recent article published in the Journal of Materials Research and Technology proposed a grain size control method to improve the durability of Al-Cu-Mg-Ag alloy at high temperatures. A relationship ...
