Careful sample preparation, electron tomography and quantitative analysis of 3-D models provides unique insights into the inner structure of reverse osmosis membranes widely used for salt water desalination wastewater recycling ...
Gold is the noblest metal—the most resistant to oxidation. However, nano-size gold has a unique ability to perform as a catalyst, even at low temperatures. The underlying mechanism for this size-dependent change in properties ...
Experts in the Nanoscale and Microscale Research Centre (nmRC) at the University of Nottingham have taken a first peak into the private life of atomic clusters.
Since life is mostly based on water, our molecules are moving, vibrating and somersaulting in a liquid environment. But electron microscopy—a technique to study a static version of this nanoworld—has been almost impossible ...
National University of Singapore scientists observe the real-time formation of hollow structures in the galvanic replacement (GR) reaction between silver and gold with nanometre resolution, gaining insights on the mechanisms ...
There's nothing quite like an ice cream on a hot day, and eating it before it melts too much is part of the fun. Ice cream is a soft solid, and its appeal is a complex combination of 'mouthfeel', taste and appearance, which ...
Gold is a metal that is chemically inactive and does not corrode, but nanoporous gold (NPG), with its sponge-like structures, acts as a catalyst to promote chemical reactions such as carbon monoxide (CO) oxidation. Its mechanisms, ...
By wrapping nickel nanoparticles in a protective shield of porous silica, A*STAR researchers have developed a highly active and robust catalyst that could help to produce methane from biomass.
Physicist Daniël Geelen (Leiden University) has developed a new microscope that uses low-energy electrons. Those are less harmful to biological and organic materials. Geelen defended his Ph.D. thesis on May 31st.
Understanding the microscopic structure of a material is key to understanding how it functions and its functional properties. Advances in fields like materials science have increasingly pushed abilities to determine these ...
