Taxol is one of the most widely used chemotherapeutic agents but is restricted by its poor solubility and severe side effects in clinical practice. To overcome these limitations, pH-sensitive nanoparticles, Acetalated Dextran-PEG-PLA-Taxol (ADPP-PTX), non-pH-sensitive nanoparticles, and Propionic Anhydride modified Dextran-PEG-PLA-Taxol (PDPP-PTX) are developed for the delivery of Taxol. Compared with PDPP-PTX, ADPP-PTX shows higher sensitivity to acid response and greater anti-proliferative effect on cancer cells.

The bulk charge recombination and the slow surface water oxidation reaction of BiVO are main unfavorable factors. In view of these disadvantages, an Fe-B electrocatalyst is loaded on BiVO to improve the PEC performance of BiVO.

However, the proton source in the photocatalytic dehalogenation process of representative halogenated aromatic pollutants by TiO is not clear. In this study, the TiO surface was modified by hydrochloric acid, sodium hydroxide, and sodium fluoride to obtain TiO samples with different hydroxyl groups.

In addition, long-lifetime photoelectrons excited in the Pr:CaTiO matrix were effectively transported through a Ag NP "bridge" into the l-cysteine chiral monolayer, due to cooperation between each component in the ternary material.
