The Improvement of Skin Whitening of Phenylethyl Resorcinol by Nanostructured Lipid Carriers.

Phenylethyl resorcinol (4-(1-phenylethyl)1,3-benzenediol) (PR) is a new whitening agent that has been found to have the ability to inhibit tyrosinase activity. However, the application of PR is limited by photo instability and poor solubility. PR-loaded nanostructured lipid carriers (PR-NLCs) were prepared by the hot-melted ultrasonic method.

Stability of paclitaxel-loaded solid lipid nanoparticles in the presence of 2-hydoxypropyl-β-cyclodextrin.

Paclitaxel (PTX)-loaded solid lipid nanoparticles without hydroxyl-β-cyclodextrin (PS) or with hydroxypropyl-β-cyclodextrin (PSC) were prepared by hot-melted sonication. Biocompatible and biodegradable stearic acid was used to produce the solid matrix. The stability of PS and PSC was assessed at different temperatures.

Microstructure and hardness of nano-sized Fe-based self-fluxing alloy powder with SiC particles.

The Fe-based self-fluxing alloy powders and SiC particles were mixed and milled by high energy ball-milling, and their microstructure and micro-hardness were investigated after subsequent compaction and sintering. The initial alloy powders with a mean size of approximately 80 microm were fined to 2.1 microm after milling at 800 rpm for 5 h.

Microstructure and magnetic properties of nano-sized Ba-Al ferrite particles by high energy ball milling.

The magnetic nano-structured Ba-Al ferrite powders were prepared by high energy ball milling under the conditions of various rotation rates and milling times. The micro structure was characterized by SEM, XRD and TEM, and the magnetic properties were obtained by VSM. As the rotation rate and milling time increased, the size of nano-sized particles gradually decreased.

Effect of spark plasma sintering on plasma electrolytic oxidation coatings on gas-atomized Mg-Zn-Y alloy containing nano-sized powders.

Mg-1.0wt%Zn-2.0wt%Y alloy powders were produced by gas atomization, and subsequently sintered by spark plasma sintering (SPS).
