Scientists are a step closer to developing a fast and cost effective camera that utilises terahertz radiation, potentially opening the opportunity for them to be used in non-invasive security and medical screening.

A research team led by Professor Emma Pickwell-Macpherson from the University of Warwick Department of Physics and involving Rayko Ivanov Stantchev and scientists from the Department of Electronic Engineering at The Chinese University of Hong Kong has reached a crucial milestone towards developing single-pixel terahertz imaging technology for use in biomedical and industrial applications.

Their single-pixel terahertz camera reached 100 times faster acquisition than the previous state-of-the-art without a...

Findings from an Oregon State University study into the effects of radiofrequency radiation generated by the wireless technology that will soon be the standard for cell phones suggest few health impacts.

Fifth generation or 5G wireless technology, which began being deployed worldwide in 2019, provides faster connectivity and more bandwidth, meaning higher download speeds.

But because 5G technology is so new, little is known about the potential health effects from its radiofrequency radiation, which is higher than the current industry standard 4G. The Oregon State study begins to change that.

“Based on our study, we don’t think 5G radiation is that harmful,” said Subham Dasgupta, a postdoctoral fellow working in the lab of Robyn Tanguay at Oregon State...

A new study reports the highest efficiency ever recorded for full roll-to-roll printed perovskite solar cells (PSCs), marking a key step on the way to cheaper and more efficient ways of generating solar energy.

A team at Swansea University’s SPECIFIC Innovation and Knowledge Centre, led by Professor Trystan Watson, has reported using a roll-to-roll fabrication method for four layers of slot-die coated PSCs.

The PSCs gave the stable power output of 12.2% – the highest efficiency recorded for four layers of roll-to-roll printed PSCs to date.

A newcomer to the p...

Researchers from the School of Chemical and Biomolecular Engineering developed an electrochemical oxidation process with the aim of cleaning up complex wastewater that contained a toxic cocktail of chemical pollutants.

“Our study, published in Algal Research, involved industrial wastewater that had been heavily contaminated with a cocktail of organic and inorganic species during a biofuel production process,” said Julia Ciarlini Jungers Soares, who is completing a PhD in Chemical and Biomolecular Engineering under the supervision of Dr Alejandro Montoya.

The wastewater, which contained carbon, nitrogen and phosphorus, was generated in a pilot plant, designed by the team for the production of biofuels using naturally abundant microalgae.

The process involved treating wastewate...
