source:Imperial College LondonGenerating energy without damaging our environment is a huge challenge in the battle against climate change. The conversion of sunlight into chemical energy to produce synthetic fuels, known as solar fuels, offers one promising solution towards a sustainable energy system.In new research published in ChemSusChem, scientists found a highly versatile and sustainable alternative catalyst to be used in solar-energy conversion, with predicted long-term improvements for energy system decarbonisation.Artificial photosynthesisArtificial photosynthesis is one mechanism of ...

source:Speaking at the European Raw Materials Alliance Summit, the European Commissioner for Internal Market, Thierry Breton, rang the alarm bell regarding the EU’s dependence on third countries for 99 products – mostly raw materials – needed for the energy-intensive industries ecosystem. Breton made a case point regarding rare earths supply, 98% of which are delivered to Europe from China, either raw or refined. SIGN UP FOR THE BATTERY METALS DIGEST“It is not an enviable position to be in, but we are not alone: the US, Japan, the UK, Canada, Australia, India and others are rushing t...

source:Science AdvancesFerromagnetically interacting Ising spins on the pyrochlore lattice of corner-sharing tetrahedra form a highly degenerate manifold of low-energy states. A spin flip relative to this “spin-ice” manifold can fractionalize into two oppositely charged magnetic monopoles with effective Coulomb interactions. To understand this process, we have probed the low-temperature magnetic response of spin ice to time-varying magnetic fields through stroboscopic neutron scattering and SQUID magnetometry on a new class of ultrapure Ho2Ti2O7 crystals. Covering almost 10 decades of time sca...

source:Investor IntelToday’s demand for critical technology enabling materials was originally brought about by (industrial) policy driven military procurement during, after, and since World War II. The continuing production of these relatively scarce materials is only made economically today possible by the additional and much larger demand of the consumer economy based not on an industrial policy but on the (regulated) free market model of capitalism. Pentagon procurement of its needs for critical materials through policy can bend the law of supply and demand, but it cannot break it. The dema...
