Heterojunction nanostructure construction and morphology engineering are considered to be effective approaches to improve photocatalytic performance. Herein, ternary hierarchical hollow structures consisting of cobalt-aluminum-layered double hydroxide (CoAl-LDH) nanoplates grown on hollow carbon nitride spheres (HCNS) and decorated with N-doped carbon quantum dots (NCQDs) were prepared using a templating method and a subsequent solvothermal process. The obtained HCNS@LDH/NCQD composites presented an improved performance in photocatalytic degradation of tetracycline and inactivation of compared with pure HCNS and LDH under visible light illumination.

Polar phase change materials beside spirooxazines not only stabilize their colored-form, but also induce thermo-regulating properties to the whole system. Moreover, encapsulation is a key route to protect them and provide safe application of photochromic materials in solid-state matrices.

Here, poly(lactide--glycolide) (PLGA) nanocomposite particles containing 5-fluorouracil (5-FU) and gold-decorated magnetite nanoparticles with a raspberry-like morphology were designed and prepared as a novel and anticancer probe. For this reason, FeO nanoparticles were synthesized by a coprecipitation method and modified with (3-mercaptopropyl) trimethoxysilane for the deposition of gold nanoparticles.

Objective: To investigate the toxicity effects of on granulosa cells (GCs) and maturation of oocytes.
Materials And Methods: GCs and oocytes were extracted from superovulated ovaries of immature mice.
This study aims to screen the effective parameters in preparing cross-linked dextran microspheres (CDMs) to make them controllable for obtaining microspheres with tunable properties. Microspheres were prepared by chemical crosslinking of dextran dissolved in internal phase of an inverse emulsion system (W/O) using epichlorohydrin (ECH). A Plackett-Burman design-of-experiments was employed as the screening methodology to investigate the effects of the kinetics and process parameters, i.
