A Tungsten-Halogen (TH) lamp is the most popular light source in NIR spectroscopy and hyperspectral imaging, which requires a warm-up to reach very high temperatures of up 250 °C take long time for radiation stabilization. Consequently, it has large enough volume enable heat dissipation prevent thermal runaway electric circuit turn out its power efficiency low. These are major barriers miniaturizing spectral systems imaging devices. However, TH lamps can be replaced by pc-NIR LEDs order...
To raise the added value of fruits Cudrania tricuspidata, tricuspidata vinegar was produced and examined for its fermentation conditions. Forty nine acetic acid bacteria with resistance against acid, ethanol, sulfide as high producers were isolated from fermented foods identified Acetobacter indonesiensis, A. cerevisiae, orientalis, tropicalis, fabarum, pasteurianus, syzygii based on results analysis 16S rRNA gene sequences. Among them, two GRAS strains, pasteurianus SCMA5 SCMA6, finally...
Highly ordered mesoporous titania films were synthesized within a short time period by controlling the pH of sols and moisture exposure as-prepared films.
Mesoporous silicas with variable pore size and two coexisting domains were synthesized by mixed systems of cationic nonionic surfactants. The sizes silica tuned modification a surfactant cetyltrimethylammonium bromide (CTAB) polyoxyethylene (10) cetyl ether (C16EO10) in acidic conditions. Various factors such as total concentration, molar composition, the amount acid affect mesophase. control dimension was achieved changing ratio to surfactants reactant gel mixtures. At small ratios C16EO10,...
The aim of this study was to develop a new functional traditional fermented soybean food using Cudrania tricuspidata fruits and fermentation microbes isolated from food. Aspergillus oryzae koji, LactoBacillus sp., Bacillus sp. were used for the selection suitable microbe fruits, as result, licheniformis SCDB 1234 selected. enhanced concentration kaempferol in 9.54 217.04 μg/g (about 22 times). DPPH radical scavenging activity materials similar that BHA BHT (92~99 ppm). tyrosinase inhibitory...
Nanocrystalline and textured NdFeB magnets were prepared from isotropic melt-spun Nd12Dy2Fe73.2Co6.6Ga0.6B5.6 powder by a modified hot-working process using direct joule heating. The magnet obtained current applied (CA) press was composed of randomly oriented Nd2Fe14B grains 50–100 nm in diameter, the optimized magnetic properties Br=0.81 T (8.1 kG), Hci=2022 kA/m (25.4 kOe), (BH)max=117 kJ/m3 (14.7 MG Oe). After CA deformation, grew to platelets with thickness 200–400 length, showed...
The photorefractive effect of a layer-structured liquid crystal cell was significantly enhanced when C60-doped poly(9-vinylcarbazole) (PVK)/TiO2 nanocomposite used in two photoconductive layers. PVK/TiO2 film prepared by infiltrating PVK into highly ordered mesoporous TiO2 layer. addition the layer to increased first-order Raman-Nath diffraction efficiency from 24% 42.9%. This enhancement is attributed blocking charge recombination composite electron transfer would decrease photogenerated...
