Oxide dispersion-strengthened (ODS) alloys are considered promising structural materials for advanced applications, particularly in nuclear reactors, due to their excellent high-temperature strength ...
Last year, many took to social media using the hashtag #NoCongoNoPhone to fight against the cobalt supply chain that fosters child labor and the exploitation of small-scale artisanal miners. The ...
As one of the most sustainable resources, wood has been widely used in the fields of construction, decoration, flooring and furniture. However, the micron-scale porous structure of wood makes it have ...
Modern synthesis methods, advanced synchrotron characterization techniques, and calculations have paved the way to precisely design the local environments of metal atoms by controlling oxygen ...
Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...
In this Letter, we experimentally report an achromatic metalens (AML) operating over a continuous bandwidth in the visible. This is accomplished via dispersion engineering of dielectric phase shifters ...
Several methods have been used to prepare titania films, and these include chemical vapour deposition (CVD), pulsed laser deposition, reactive sputtering and sol-gel deposition. The sol-gel technique ...
