Hexagonal tungsten oxide nanorods are highly promising for sodium-based near-infrared electrochromic windows. However, conventional dopants limit the performance of these devices. In a new study, researchers have leveraged thermally removable dopants to unlock the electrochromic capacity of sodium-based smart windows, paving the way for enhanced thermal regulation and efficient energy consumption in buildings and automobiles.  

Ammonia is a promising hydrogen carrier and fertilizer, with growing potential as a low-carbon fuel. However, conventional production is highly energy-intensive and contributes significantly to greenhouse gas emissions. In a new study, researchers developed a dual chemical looping strategy for ammonia synthesis that avoids several energy-intensive steps used in traditional processes. An integrated 4E analysis showed improved efficiency and robustness while reducing production costs.

Scientists have developed a new way to fabricate three-dimensional nanoscale devices from single-crystal materials using a focused ion beam instrument. The group used this new method to carve helical-shaped devices from a topological magnet composed of cobalt, tin, and sulfur.

A nanostructure made of silver and an atomically thin semiconductor layer can be turned into an ultrafast switching mirror device that may function as an optical transistor – with a switching speed around 10,000 times faster than an electronic transistor. An international team of researchers led by the University of Oldenburg, Germany, describes this effect in a paper published in the current issue of Nature Nanotechnology. Ultrafast light switches offer interesting prospects for optical data processing, chip manufacturing, optical sensors or quantum computers.

Spin-out PeroCycle, which is developing a closed carbon loop system to decarbonise foundation industries, announces two new appointments strengthen the company’s leadership team at a pivotal stage of growth.
