    2021-2-4 · 2.2. Synthesis of Nanosized SO 4 2-/TiO 2. 1 g aboveobtained TiO 2 was put into a Teflon flask before adding 150 mL of H 2 SO 4 0.7 M (diluted from H 2 SO 4 99%, Sigma-Aldrich). After that, the mixture was hydrothermalized at 170°C for 24 hours using an autoclave. At the end of the hydrothermal process, the suspension was washed and dried at 105°C for 2 hours, obtaining the nanosized SO 4 2 ...

  • Lasing in robust cesium lead halide perovskite

    2016-2-23 · Nanowire lasers are miniaturized light sources with great potential for integration into optoelectronic circuits. Many of the current nanowire lasers either require extreme conditions for synthesis or suffer from poor operational stability. We synthesize nanowires of a promising set of compositions, the cesium lead halides, and accomplish this under near-ambient conditions.

  • Embedded droplet printing in yield-stress fluids | PNAS

    2020-3-17 · Conventional microfluidic methods primarily rely on fluids that behave in simple ways, like water. Yield-stress fluids are materials that behave in a complex way, dramatically transitioning between solid-like and liquid-like behavior, depending on an applied stress. We introduce embedded droplet printing—a system for the generation and manipulation of fluid droplets within yield-stress fluids.

  • (IUCr) Acemetacin cocrystals and salts: structure

    Acemetacin (ACM) is a non-steroidal anti-inflammatory drug (NSAID), which causes reduced gastric damage compared with indomethacin. However, acemetacin has a tendency to form a less soluble hydrate in the aqueous medium. We noted difficulties in the preparation of cocrystals and salts of acemetacin by mechanochemical methods, because this drug tends to form a hydrate during any kind …

  • Pro-resolving lipid mediator lipoxin A4 attenuates

    Derada Troletti et al. demonstrate that boosting a protective resolution response by lipoxin A4 (LXA4) suppresses clinical signs in a neuro-inflammatory animal model for multiple sclerosis (MS). They provide critical mechanistic insights into LXA4-mediated amelioration of neuro-inflammation and thereby highlight the potential clinical application of LXA4 for MS.

  • Crystallisation properties of amorphous cyclodextrin ...

    2019-2-13 · Water-induced crystallisation of amorphous core-cyclodextrin (CD) complex is an essential step in a solid encapsulation process and removal of added water is a challenging. Ethanol addition is expected to shorten the complex dehydration time. This study investigated crystallisation of amorphous spray-dried α-, β- and γ-CD powders by direct mixing 15% (w/w) of ethanol:water mixture (0:100 ...
