Methanol-assisted oxidation of organic compounds in supercritical water (SCW) is interest for wastewater treatment. To provide better predictive tools this process, it important to develop kinetic models. This paper investigated the kinetics methane and methane/methanol mixtures SCW. A detailed chemical model was established, drawing on analogy between chemistry SCW gas phase. The performance e...

Far-infrared (FIR) irradiation and subcritical water were applied for recovering antioxidant compounds from rice hulls (RHs). After 30 min of FIR treatment at 100°C, the radical scavenging activity (RSA) and total phenol contents (TPC) of RH extracts increased from 47.74% to 79.63% and from 0.12 mM to 0.19 mM, respectively, compared to control. The inhibition of lipid peroxidation in extracts w...

Graded activity of the DPP signaling pathway is critical for specification of dorsal embryonic cell fates in Drosophila. We present evidence that a second BMP ligand, SCW, potentiates DPP activity. Using dominant-negative forms of the type I receptors SAX and TKV, we demonstrate that SAX mediates the SCW signal, while TKV is required for both DPP and SCW activity. We find that while DPP/TKV sig...

Super- and sub-critical water treatments have been of interest as novel methods for protein hydrolysis. In the present study, we studied the effect of sub-critical water (Sub-H2O, 300℃, 80 bar) treatment as well as super-critical water (Super-H2O, 400℃, 280 bar) treatment on the physicochemical properties of porcine skin (PS), which has abundant collagen. Porcine skin was subjected to pre-therm...

We report the results of treating a dense, chemically produced silver colloidal suspension with high-power laser pulses and with exposure to supercritical water (SCW) conditions. The initial colloid has a mean particle diameter measured by transmission electron microscopy to be 28.4 nm and exhibits a broad absorption band in the visible region with a small maximum near 420 nm. Both treatments r...

Secondary cell walls (SCWs) have critical functional importance but also constitute a high proportion of the plant biomass and have high application potential. This is true mainly for the lignocellulosic constituents of the SCWs in xylem vessels and fibres, which form a structured layer between the plasma membrane and the primary cell wall (PCW). Specific patterning of the SCW thickenings contr...

Propylene glycol monomethyl ether acetate (PGMEA) photoresist solvent and monoaromatics are typical organic pollutants found in the wastewater discharged from semiconductor manufacturing processes. Conventional treatment technologies, however, remain mostly ineffective to eliminate these aqueous streams. Herein, we developed a novel strategy for highly efficient degradation of PGMEA archetypal ...

In this paper, a novel 3D face recognition scheme by Sliding Complex Wavelet Structural SIMilarity (SCW-SSIM) index carried out on detailed geometry images is proposed. First, the preprocessed 3D faces are mapped into geometry images on 2D plane. Then, a multi-scale wavelet transform is designed to decompose geometry image into a set of sub-images and denotes high-pass sub-images of wavelet tra...

Inbred Lewis (LEW/N) female rats develop an arthritis in response to group A streptococcal cell wall peptidoglycan polysaccharide (SCW), which mimics human rheumatoid arthritis. Histocompatible Fischer (F344/N) rats do not develop arthritis in response to the same SCW stimulus. To evaluate this difference in inflammatory reactivity, we examined the function of the hypothalamic-pituitary-adrenal...
