A 3D printer that can take the heat, breathing tech to keep firefighters safe and a ventilator design printed for less than $170. Large groups of makers, engineers, and medical professionals collaborate to make open-source solutions that can be reproduced and assembled locally worldwide.
A team of scientists including WMG at the University of Warwick combined their knowledge and expertise to assess the current status of the Na-ion technology from materials to cell development, offering a realistic comparison of the key performance indicators for NBs and LIBs.
The disruptive inventions that make people go "Wow!" tend to come from research in the heart of cities and not in the suburbs, a new study suggests. Researchers found that, within metro areas, the majority of patents come from innovations created in suburbs. But the unconventional, disruptive innovations - the ones that combine research from different technological fields - are more likely to be produced in cities,
The discovery could help battery researchers design the first solid electrolytes that are safe, cheap and efficient.
New paper in Nature Energy, reveals how researchers fully identified the nature of oxidised oxygen in the important battery material - Li-rich NMC - using RIXS (Resonant Inelastic X-ray Scattering) at Diamond Light Source. This compound is being closely considered for implementation in next generation Li-ion batteries because it delivers higher energy density than current materials, and could translate to longer driving ranges for electric vehicles and enable scientists to tackle issues like battery longevity and voltage fade
While the power conversion efficiency of perovskite solar cells (PVSCs) has already greatly improved in the past decade, the problems of instability and potential environmental impact are yet to be overcome. Recently, scientists from City University of Hong Kong (CityU) have developed a novel method which can simultaneously tackle the leakage of lead from PVSCs and the stability issue without compromising efficiency, paving the way for real-life application of perovskite photovoltaic technology.
Copper stearate was used as the basis for this catalyst test and showed efficiency for in-situ oil combustion.
The fixed fluidized bed technology is already widely used overseas, but is relatively new for the Russian oil industry. To improve it, the KFU scientists mixed coke particles with quartz sand. This created a sort of a "freeze" in the porous layer and simplified the study of the kinetics of petroleum coke combustion in the presence of catalysts.
Researchers at The University of Tokyo and Fudan University furthered our understanding of the crystallization process in confined spaces by visualizing the ordering of colloidal particles in a droplet. The team conducted real-time microscopic observations of the assembly of colloidal particles in droplets to clarify the crystallization process. They found that the kinetically controlled interactions between particles affected the order of the final crystal. Their results take us closer to realizing controlled crystal formation.
Researchers at the Paul Scherrer Institute PSI and from ETH Zurich want to make so-called zeolites more efficient. Today, these compounds are already indispensable additives in the chemical industry and have been used as catalysts in oil refineries since the 1960s. Now, in the journal Nature Materials, the researchers advocate paying more attention to the classic zeolites. These, they assert, would even have the potential to make a bioeconomy based on renewable resources possible.
