ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.

Investigation into Lean-Burn Combustor Thermo-acoustic Instabilities: Modelling of Entropy Convection for Low Frequency Rumble Prediction [PDF]
New combustion methods, aimed to reduce emissions, are shown to be susceptible to instability. To reduce nitrogen oxides, the traditional diffusion flame is replaced by lean combustion, where fuel-air are partially premixed, and combustion conditions are
