Cellulose aerogel is an advanced thermal insulating biomaterial. However, the application of cellulose in insulation still faces critical problems, for instance, relatively low strength and large pore size without Knudsen effect. In this study, a silica areogel made from olivine rather than traditional tetraethoxysilane or water glass employed to synthesize silica-cellulose composite applying f...

in this work, we investigated synthesis, magnetic properties of silica coated metal ferrite, (cofe2o4)/sio2 and manganese doped cobalt ferrite nanoparticles (mnxco1-xfe2o4 with x= 0.02, 0.04 and 0.06)/sio2 for possible biomedical application. all the ferrites nanoparticles were prepared by co-precipitation method using fecl3.6h2o, cocl2.6h2o and mncl2.2h2o as precursors, and were silica coated ...

background: recently, some new nanobiosensors using different nanoparticles or microarray systems for detection of mycotoxins have been designed . however, rapid, sensitive and early detection of aflatoxicosis would be very helpful to distinguish high-risk persons.objectives: we report a highly sensitive competitive immunoassay using magnetic/silica core shell as a signal intensifier for the de...

An optically transparent and thermally insulating (OTTI) silica aerogel demonstrates promising results for various solar thermal applications, particularly concentrated power systems. Higher system efficiency can be achieved by integrating OTTI materials reducing heat loss at higher receiver temperature. However, the stability of aerogels has been one limiting factors. Here, we report that Al2O...

We report theoretical results for heat transport by quasiparticle excitations in superfluid $^3$He infused into silica aerogel engineered with uniaxial anisotropy. For this system two distinct equal spin pairing (ESP) phases have been reported based on NMR spectroscopy. Theoretical analysis predicts the first ESP state to be chiral A phase axis aligned along strain axis, and lower temperature a...

recent investigations have been shown that inorganic nanomaterials including gold nanoparticles, nonporous and mesoporous silica nanoparticles, magneticnanoparticles, and quantum dots have shown great potential in bioimaging, targeted drug delivery, and cancer therapies. biocompatibility, ease of synthesis, and ease of surface functionalization are among the significant properties of nonporous ...

Silica aerogel is a class of nanoporous material with extremely high porosity (85–99.9 %) and specific surface area (500–1200 m2/g), as in cause very low density, thermal conductivity. But silica have some disadvantages. One this disadvantages cost. In study, to solve problem has been used cost precursor which rice husk ash. Also, we try improve porosity. To the expanded perlite (EP). produced ...
