Microfluidic-assisted sol-gel preparation of monodisperse mesoporous silica microspheres with controlled size, surface morphology, porosity and stiffness.

The controllable synthesis of monodisperse mesoporous silica microspheres with unique physicochemical properties is becoming increasingly important for a variety of applications such as catalysts, chromatography, drug delivery and sensors. Here, we report a facile microfluidic-assisted sol-gel method for the preparation of silica microspheres with precisely controlled properties such as the size of the microspheres, the surface morphology, porosity and stiffness. All these properties can be manipulated by changing specific synthesis parameters, such as changing the microfluidic channels to tune the size of the microdroplets (tens to hundreds of microns), changing the contents of the precursor solution to manipulate the surface morphology (wrinkled to smooth surface) and changing the gelation/annealing conditions to tune the porosity (surface area up to 1021 m g) and stiffness of the microspheres (elastic modulus tunable from 0.

Suckling Rat Pup Model: Do Caprine Milk Lactoferrin and Immunoglobulins Have Different Digestion and Absorption Properties from That of Human and Bovine Species?

This study aimed to investigate the digestion and absorption properties of caprine milk serum proteins in comparison to human and bovine species by using rat pups to mimic preterm infants. The results indicate that caprine lactoferrin (LTF) had a shorter retention time in the intestine and released a greater number of fragments, resembling human milk LTF more closely. In contrast, caprine immunoglobulins (Igs) were similar to bovine Igs and both exhibited a longer retention time in the intestine.

Superstrong Lightweight Aerogel with Supercontinuous Layer by Surface Reaction.

Breaking the thermal, mechanical and lightweight performance limit of aerogels has pivotal significance on thermal protection, new energy utilization, high-temperature catalysis, structural engineering, and physics, but is severely limited by the serious discrete characteristics between grain boundary and nano-units interfaces. Herein, a thermodynamically driven surface reaction and confined crystallization process is reported to synthesize a centimeter-scale supercontinuous ZrO nanolayer on ZrO-SiO fiber aerogel surface, which significantly improved its thermal and mechanical properties with density almost unchanged (≈26 mg cm). Systematic structure analysis confirms that the supercontinuous layer achieves a close connection between grains and fibers through Zr─O─Si bonds.
