Stirring can allow the dispersion of substances evenly in liquid. Einstein's tea leaf paradox is a concept that shows how tea leaves can concentrate in a doughnut shape through a secondary flow effect during stirring. In ...
Direct conversion of methane (CH4) to high-value-added chemicals at room temperature, by directly using abundant and low-cost molecular oxygen (O2) as an oxidant, is an ideal route for CH4 utilization. But it remains a challenge ...
