Concrete, the most widely used material in the construction industry, has a history dating back to the Roman Empire. Now, engineers at the University of Pittsburgh are reimagining its design for the 21st century.
2D monolayer nanosheets composed of layered perovskite come with several attractive properties. But, it has been challenging to build them with tunable bandgaps in the visible region with no addition of oxygen defects.
Scientists have transformed single-cell algae into functional perovskite materials. The team, led by scientists at the B CUBE–Center for Molecular Bioengineering at TU Dresden, converted mineral shells of algae into lead halide perovskites with tunable physical properties.
Alloys that can return to their original structure after being deformed have a so-called shape memory. This phenomenon and the resulting forces are used in many mechanical actuating systems, for example in generators or hydraulic pumps.
Manchester based Watercycle Technologies Ltd, a deep tech company focused on developing sustainable, high-yield, low-cost, mineral extraction and water treatment systems has signed an agreement with Energia Minerals Srl, a subsidiary of ASX listed Altamin Limited, to produce lithium carbonate from Energia’s Galería EL geothermal brine projects in the Lazio Region of central Italy utilising Watercycle’s proprietary Direct Lithium Extraction and Crystallisation technology.
Researchers from the Indian Institute of Technology Gandhinagar, Sandia National Laboratories, and Lawrence Berkeley National Laboratory worked together to construct 3–4 nm ultrathin nanosheets of a metal hydride that boosts hydrogen storage capacity. The study is published in the journal Small.
A research group headed by Professor Hui Wang and Associate Professor Zhigao Sheng from the Chinese Academy of Sciences reported the synthesis of polyvinylpyrrolidone-directed nickel nanowires (PNNWs) via solvothermal technique supported by a strong magnetic field in a work published in Advanced Materials Interfaces.
Carnegie Mellon University's Yongxin (Leon) Zhao and the Chinese University of Hong Kong's Shih-Chi Chen have a big idea for manufacturing nanodevices.
A recent study published in the journal Nature Communications focuses on this issue by presenting an extremely configurable soft nanobrush-directed technique for accurate in situ production of MOF nanoarrays on various surfaces.
As far as metasurfaces have been concerned, surface lattice resonances (SLRs) and bound state in the continuum (BIC) are two suitable methods for obtaining high-quality factors (Q-factors).
