Exploiting high speed light for super slow science


Scientists at the world's premier science conference - the American Association for the Advancement of Science (AAAS) annual meeting - will this year be discussing the advances enabled by the UK's pioneering Long-Duration Experiment facility (LDE). Unmatched anywhere in the world, the LDE allows ...


Bury nuclear waste down a very deep hole, say UK scientists

Deep borehole disposal of high level nuclear waste


Scientists at the University of Sheffield calculate that all of the UK's high level nuclear waste from spent fuel reprocessing could be disposed of in just six boreholes 5km deep, fitting within a site no larger than a football pitch.The concept - called deep borehole disposal - has been ...


Nuclear waste could be reduced by 90 percent


The researchers, from the University of Sheffield's Faculty of Engineering, have shown that mixing plutonium-contaminated waste with blast furnace slag and turning it into glass reduces its volume by 85-95 per cent. It also effectively locks in the radioactive plutonium, creating a stable end ...


Quantitative analysis of solvent effects on molecular recognition


Scientists in the UK are attempting to understand the host–guest chemistry of molecular cages in solution by separately quantifying the free energy contributions of (at least) three host–guest interaction mechanisms that usually work in unison: hydrogen-bonding, non-polar interactions and ...


Innovations in soil science will grow the solutions to global food security


A report published by the Royal Society of Chemistry (RSC) says that innovative research in soil science will be fundamental in overcoming the growing threat of global food and fuel crop shortages as the world’s population continues to increase. Food security is one of the great global challenges ...


World's tiniest mirror


Just as the path of photons of light can be directed by a mirror, atoms possessing a magnetic moment can be controlled using a magnetic mirror. Research reported in the Journal of Applied Physics investigates the feasibility of using magnetic domain walls to direct and ultimately trap individual ...


Scientists' breakthrough in production of biofuels


A team of scientists from the University of Sheffield have scooped an international award in recognition of their work on an innovative device which will make the production of alternative biofuels more energy efficient. The research team has adapted a unique bioreactor for use in the production ...


Switchable Adhesive

Gel- and polymer-coated surfaces stick together and separate in response to an environmental stimulus


Two surfaces stick together, separate, and stick together again - on command. This discovery by a team of researchers from the Universities of Sheffield (UK) and Bayreuth contradicts our day-to-day experience. In the animal kingdom, geckos can climb up vertical inclines, displaying an incredible ...


Carbon monoxide releasing complexes as new pharmaceutical agents?


Toxicity depends on the dosage: Carbon monoxide (CO) is known as a toxic gas, responsible for the deadly effect of auto exhaust in closed garages, for example. Paradoxically, the human body itself produces 3 - 6 cm3 of CO daily. Certain diseases cause this quantity to increase, which can be ...
