A sustainable and effective method for de-oxygenation of few-layer graphene oxide (FLGO) by glycerol gasification in supercritical water (SCW) is described. In this manner, reduction of FLGO and valorization of glycerol, in turn catalyzed by FLGO, are achieved simultaneously. The addition of glycerol enhanced FLGO oxygen removal by up to 59% due to the in situ hydrogen generation as compared to...

The surface cold working (SCW) of austenitic stainless steel (SS) causes martensitic transformation in the layers, and percentage fraction strain-induced martensite depends on degree SCW. Higher content α′−martensite increases micro-hardness fatigue strength, but deterioration corrosion resistance is possible. Therefore, desired operational behaviour SS can be ensured by corresponding SCW heat ...

The fact that the deep-ocean benthic δ13C minimum shifted from the North Pacific to the South Atlantic during the Last Glacial Maximum is often interpretted as evidence of a change in deep water circulation, such as the development of deep water ventilation in the North Pacific or a decrease in Southern Ocean overturning. This study reevaluates the implications of changes in benthic δ13C gradie...

OBJECTIVE The goal of this study was to investigate the role of endogenous interleukin 12 (IL12) in acute murine streptococcal cell wall (SCW) arthritis. METHODS C57black/6 mice were injected intraperitoneally with rat anti-murine IL12 (C17.8), shortly before induction of arthritis by intra-articular injection of 25 microg SCW fragments into the right knee joint. Joint swelling and chondrocyt...

Vascular tissues are important for transporting water and nutrients throughout the plant and as physical support of upright growth. The primary constituents of vascular tissues, xylem, and phloem, are derived from the meristematic vascular procambium and cambium. Xylem cells develop secondary cell walls (SCWs) that form the largest part of plant lignocellulosic biomass that serve as a renewable...

With the growing demand for energy and the depletion of conventional crude oil, heavy oil in huge reserve has attracted extensive attention. However, heavy oil cannot be directly refined by existing processes unless they are upgraded due to its complex composition and high concentration of heteroatoms (N, S, Ni, V, etc.). Of the variety of techniques for heavy oil upgrading, supercritical water...

The RADARSAT-2 satellite is Canada's next-generation C-band synthetic aperture radar (SAR) satellite launched in December, 2007. RADARSAT-2 products are characterized by the beam mode used by the satellite and the level of processing that has been applied to the data. This paper examines the speckle characteristics observed on RADARSAT-2 dual polarization products. This work is based on two SLC...

Background Transcription factors (TFs) play important roles in the regulation of secondary cell wall (SCW) biosynthesis in herbaceous and woody plants. In Arabidopsis, the onset of SCW deposition is initiated by a nexus of NAC, MYB, homeodomain and several other families of TFs, which function in a transcriptional network regulating SCW biosynthetic genes. NAC family members SND1/ NST1 and VND6...
