A new fabrication technique for substantially enhancing the prospects of commercializing perovskite solar cells through improved stability, reliability, efficiency and affordability is underway at City University of Hong Kong (CityUHK). Published in Science, the research is significant because the simple device structure that the CityUHK team has built can facilitate future industrial production and enhance confidence in the […]

The process of testing new solar cell technologies has traditionally been slow and costly, requiring multiple steps. Led by a fifth-year Ph.D. student, a Johns Hopkins team has developed a machine learning method that promises to dramatically speed up this process, paving the way for more efficient and affordable renewable energy solutions. “Our work shows […]

In 2024, more than 1 in 5 cars sold is an electric vehicle (EV). Intergovernmental agencies estimate that by 2035, half of all new cars sold globally will be EVs. While more EVs on the road sounds like great news for the environment, it could lead to complications. The electric grid is not yet ready […]

GM will discontinue the Ultium battery brand name as it looks to expand the types of cells and chemistries it uses in its electric vehicles. During an investor event today, Kurt Kelty, GM’s VP of batteries and a former Tesla executive, announced plans to adopt lithium iron phosphate (LFP) battery technology in order to decrease […]

How did Sensmet get started? The initial idea to build an online system that uses a micro-plasma to analyse metals in liquids came from Toni Laurila, who is now Sensmet’s co-founder and CEO. He got the idea during his post-doctoral studies at the University of Cambridge, UK, and after he returned to Finland, we started […]

University researchers in China have made a potentially massive breakthrough in battery technology that could make large-scale versions even more affordable and widely available. According to Interesting Engineering, scientists at the Dalian Institute of Chemical Physics have created new molecules for aqueous organic flow batteries. The new organic redox-active molecules, or ORAMs, could make the […]

In a new Nature Communications study, researchers propose a new method for hydrogen storage using existing pipes located at the bottom of lakes and reservoirs. Hydrogen has surfaced as a promising alternative to fossil fuels for energy generation in several industries. The focus is especially on green hydrogen, which is produced via electrolysis of water […]

On average, Americans spend about 90% of their time indoors, and the air we breathe at work, school or home affects our overall health and well-being. Most air purification systems, however, are expensive, cumbersome and require frequent cleaning or filter replacement to function at optimum levels. Binghamton University Professor Seokheun “Sean” Choi and Ph.D. student […]

Reducing carbon emissions is crucial to curbing the effects of climate change, but usually gas-powered vehicles and manufacturers are the most conspicuous culprits. However, Information and Communication Technology (ICT) is currently responsible for between 2 and 4% of the global carbon footprint, which is on par with aviation emissions. ICT emissions are expected only to […]

As many as 249 lives could have been saved in London during the 2018 record-setting hot summer had the city widely adopted cool roofs, estimates a new study by researchers at UCL and the University of Exeter. The paper, published in Nature Cities, analyzed the cooling effect that roofs painted white or other reflective colors […]
