Template-free synthesis of single-crystal SrTiO nanocages for photocatalytic overall water splitting.

In this study, we present a novel approach to achieve the template-free fabrication of nanocage-shaped SrTiO (N-STO) single crystals molten salt flux treatment. Systematic characterizations demonstrate the high crystallinity and low defect density of N-STO. The N-STO single crystals enable overall water splitting (OWS) with hydrogen and oxygen evolution rates of 100.

Preparation and distribution of 5-fluorouracil (125)I sodium alginate-bovine serum albumin nanoparticles.

AIM:To prepare 5-FU sodium alginate(125)I bovine serum albumin nanoparticles (BSA NP), to determine the radioactive count in different organs of rats at different time points after oral administration of 5-FU (125)I sodium alginate-BSA NP and to calculate the kinetic parameters of its metabolism.METHODS:Emulsion solidification method was used to prepare 5-FU (125)I sodium alginate-BSA NP, and to determine its diameter under transmission electronic microscope (TEM). Then the rate of NP and external drug releasing velocity were measured.
