Moisture-Resistant Perovskite Solar Cells Based on Low-Cost Dye [Video]
Dopant-free, moisture-resistant hole-transport materials (HTMs) for perovskite solar cells based on derivatives of the dye anthanthrone (ANT) are developed by Sagar M. Jain from Swansea University Bay Campus, Prashant Sonar from Queensland University of Technology, and co-workers.
Laying Waste to Oil Spills
An international team have used waste cooking oil from a university cafe to make a cheap, effective material for absorbing oil from seawater.
Nature-Inspired Surface and Materials Research at Beihang University
A recent special issue of Advanced Materials, issue 45 in 2017, was dedicated to highlighting nature-inspired surface and materials research at Beihang University in Beijing, China.
New Customized Compostable Materials
A Spanish consortium of indutry and science is seeking for new compostable materials for mass-market single-use products like tableware, packages and single-use bags.
Cloak of Inv sib ity
A true invisibility cloak would encompass an object, and manipulate light, in a manner such that it traveled around the object, rather than reflecting off it. A recent paper reports some exciting progress toward such a design.
Enhancing Catalyst Stability for Polypropylene Production
The important role of surface-bound hydroxy groups of vanadium catalysts under reaction conditions by employing in situ DRIFTS experiments and DFT calculations is elucidated.
Infrared-Driven Generation of Hydrogen Gas
IR-driven transfer of plasmon-induced hot electrons in a nonmetallic branched heterostructure, by combining ultrafast transient absorption spectroscopy with theoretical simulations, is demonstrated for the first time.
