The problem in using titanium dioxide as a photocatalyst is recombination of electron and hole. One strategy for inhibiting theirs recombination is to add other electron accepters to the reaction. It can reduce the electron/hole recombination and then produce more ·OH on the surface of titanium dioxide, from which increased the degradation rate of the pesticide.

二氧化钛作为光催化剂进行光催化降解的问题在于电子—空穴对的重新复合，抑制其重新复合的一种办法是加入其他的电子接受体，减少电子—空穴对的复合，从而使光催化剂TiO2表面产生更多的·OH自由基，加强农药的光催化降解。

The electron location function shows the electronic density changes at both the atomic vacancies and antisites. There is an obvious absence of electronic areas where the vacancy of Ga has the dangling bonds of N, which are favourable for the sdsorption of metal atoms. In contrast, at the vacancy of N, there is more electron distribution(ELF:0.16-0.45), forming lone electron pairs which are profitably available to combine electronegative atoms.

Based on the structure, those human diseases related mutation sites are mapped onto the structure accurately. As a result, it is found that these sites are all around the electron transfer prosthetic groups or ubiquinone. And these mutations will alter prosthetic groups' binding or ubiquinone's binding, causing electron leakage from the prosthetic groups in the electron transfer chain, producing reactive oxygen species and leading to tumor formation.

利用线粒体复合物 II 的结构对已知与人类疾病相关的该复合物突变位点进行了精确定位，发现这些突变位点均位于电子传递体或辅酶 Q 结合位点的周围，它们的突变或影响了电子传递体的结合，或影响了辅酶 Q 的结合，从而导致电子传递的中断，电子逃逸到线粒体基质中或线粒体内膜中，经过一系列下游途径导致疾病的产生。
