Unexpected Intrinsic Catalytic Function of Porous Boron Nitride Nanorods for Highly Efficient Peroxymonosulfate Activation in Water Treatment.

Porous boron nitride (BN) nanorods, which were synthesized via a one-stage pyrolysis, exhibited excellent catalytic performance for organics' degradation via peroxymonosulfate (PMS) activation. The origin of the unexpected catalytic function of porous BN nanorods was proposed, in which non-radical oxidation driven by the defects on porous BN dominated the sulfamethoxazole degradation via the generation of singlet oxygen (O). The adsorption energy between PMS and BN was calculated via density functional theory (DFT), and the PMS activation kinetics were further investigated using an electrochemical methodology.

A novel phenotype-based approach for systematically screening antiproliferation metallodrugs.

Ruthenium (Ru) derivatives have less toxicity and higher water-solubility than cisplatin, giving them great potential as antitumor metallodrugs. In this study, zebrafish were employed as a whole-organism model to screen new Ru compounds for anti-cell proliferation activity. After soaking fish embryos in cisplatin and five Ru derivatives, [Ru(terpy)(bpy)Cl]Cl, [Ru(terpy)(dppz)OH(2)](ClO(4))(2), [Ru(terpy)(tMen)OH(2)](ClO(4))(2), [Ru(terpy)(Me(4)Phen)OH(2)](ClO(4))(2), and Ru(bpy)(2)Cl(2), only cisplatin and [Ru(terpy)(bpy)Cl]Cl-treated embryos displayed obvious phenotypic effects, such as fin-reduction.
