Recently, frequent discharge of water-ladened emerging organic pollutants such as Bisphenol A has elicited serious concern due to its pernicious effects on public health and the ecological environment. In this study, hematite nanoparticles (Fe2O3) were synthesized via sol–gel auto-combustion technique incorporated a nanofiller fabricate PVDF-PEG nanocomposite hollow fibre membrane with enhanced...

We report the effect of surplus-Fe-content, and thermal annealing on properties sol gel auto-combustion synthesized Co 1–x Fe 2+x O 4 (x = 0.0–0.8) spinel ferrites. X-ray diffraction (XRD), magnetic measurements, Fourier transform infrared (FTIR) spectroscopy, Ultraviolet–visible (UV–Vis) are used to monitor excess Fe-content, dependence properties, correlation among them. XRD validates presenc...

The sol–gel technique is a highly flexible technique for fabrication of oxide glasses, and various researchers have previously reported fluorescence studies of Er-doped sol–gel films and monoliths. Here we report the fabrication of Er-doped strip-loaded sol–gel silicate waveguides, using a silica–titania–alumina host composition, and Er concentrations up to f1.1=10 Er rcm, for possible applicat...

Controlled release silica sol gels are room temperature processed, porous, resorbable materials with generally good compatibility. Many molecules including drugs, proteins and growth factors can be released from sol gels and the quantity and duration of the release can vary widely. Processing parameters render these release properties exquisitely versatile. The synthesis of controlled release s...

In this report, a novel silk fibroin hydrogel with a reversible sol–gel transition capacity is presented, in which the base material of this reversible hydrogel is hydrophilic silk fibroin (HSF) obtained by immersing a dried regenerated Bombyx mori silk fibroin (SF) condensate in deionized water (DI water) and collecting its lixivium. The resulting HSF sol can exhibit an enhanced sol–gel transi...

Amoeboid locomotion is one of the typical modes of biological cell migration. Cytoplasmic sol-gel conversion of an actomyosin system is thought to play an important role in locomotion. However, the mechanisms underlying sol-gel conversion, including trigger, signal, and regulating factors, remain unclear. We developed a novel model system in which an actomyosin fraction moves like an amoeba in ...

A transparent fire protective sol-gel coating deposited on wood has been evaluated using different tests, such as mass loss cone, mini single burning item and furnace tests. The heat release rate total during combustion, but also the flame spread behavior thermal protection performances of coatings have studied. Two processes to apply assessed show thickness dependence performance. When a thick...

incorporation of copper species into silica matrix was performed by the sol-gel method. copper ions and copper particles were doped using two different copper sources; cu(no3)2.3h2o and copper particles chemically synthesized.the particles of copper metallic, cuprous and cupric oxide were prepared and the synthesis and characterizations of copper species were compared together. on the other han...
