edited by Sadie Harley, reviewed by Andrew Zinin Many scientists are trying to develop catalysts to make NH₃ synthesis possible under milder conditions. Although some high-performance catalysts have been reported, they often rely on scarce noble metals, such as ruthenium. Barium (Ba)-based materials could be a cost-effective alternative, but highly…
Creating better-performing materials comes down to having more control over their structure at the smallest possible scale. One particularly effective way to accomplish that is using nanoparticles, which have highly customizable shapes and sizes and have already shown promise in applications across energy, medicine, and electronics. Joining Macfarlane on the…
Scientists have developed a remarkable new molecular motor that spins when electricity passes through it. Inspired by an ancient invention, the tiny machine can even reverse its direction when the electrical voltage is switched.…
This work presents a comprehensive analysis of the load stepping method in digital photoelasticity, examined through four complementary perspectives: the classical formulation of load stepping, its extension using…
A key focus of the discussion was the potential integration of MIT CBI’s portable electrochemical reader with NANOTEC’s disposable electrochemical sensor strips. This integrated approach aims to enable rapid and convenient…
When Linda Nazar learned she would receive Canada’s most prestigious scientific award, she could hardly believe it. “I felt quite honestly both humbled and inspired,” the University of Waterloo chemist told Quirks & Quarks. “It’s a real honour and I’m thrilled and deeply appreciative of receiving this and frankly I…
To evaluate the reaction energies of the HIR and WFR in oxide materials, several atomic reactions were considered. The HIR refers to the reaction of an interstitial H atom binding with lattice oxygen to form a lattice OH with: where R is the gas constant; T is the temperature. The…
Chemistry PhD candidate Kate Fraser won 3rd place in the 2022 Young Persons’ World Lecture Competition (YPWLC) with her presentation on the untapped potential of highly conductive plastics in addressing the global energy crisis.…
