متن کاملHigh power rechargeable magnesium/iodine battery chemistry
Rechargeable magnesium batteries have attracted considerable attention because of their potential high energy density and low cost. However, their development has been severely hindered because of the lack of appropriate cathode materials. Here we report a rechargeable magnesium/iodine battery, in which the soluble iodine reacts with Mg2+ to form a soluble intermediate and then an insoluble fin...
متن کاملThe Power of Thiol-ene Chemistry
As a tribute to Professor Charlie Hoyle, we take the opportunity to review the impact of thiol-ene chemistry on polymer and materials science over the past 5 years. During this time, a renaissance in thiol-ene chemistry has occurred with recent progress demonstrating its unique advantages when compared with traditional coupling and functionalization strategies. Additionally, the robust nature o...
متن کاملSolid-state chemistry of lithium power sources†
This article describes the solid-state chemistry of intercalation compounds that underpins a revolutionary new rechargeable lithium battery which has recently achieved phenomenal commercial success. The battery can store more than twice the energy compared with conventional alternatives of the same size and mass and holds the key to the future improvement of consumer electronic products (e.g. m...
متن کاملImpact of Power Play Overs on the Outcome of Twenty20 Cricket Match
This study attempts to find if better performance in power play leads a team to victory in a Twenty20 match. Based on the methodology devised to do so, the study tries to measure the performance of both the teams during power play overs in terms of batting and bowling. The developed measure is called ‘Prod’ which is a product of the difference of batting and bowling performance of t...
