The accumulation mechanism of Cd and Pb in raddish roots was studied. The results showed that in the first 12 hours the accumulation process of Pb in roots was probably due to rapid adsorption, later, to slow chemical precipitation and cell absorption. Especially, at high Pb content, chemical precip...

Phase-locked loop (PLL) is a negative feedback control system that can achieve phase synchronization of two signals. Its filtering effect can make its passband narrow, and its output frequency automatically track the input frequency. Phase locked loops are often used in atomic clocks, frequency stan...

Abstract Developing a new strategy to address water vapor poisoning is crucial for catalysts in real‐working conditions. Except for the traditional thinking of resistance enhancement, a reverse idea is proposed herein of utilizing the inevitable H2O, converting it to active ·OH to enhance the overal...
