Concentrations of cationic surfactants in aqueous solutions have been estimated on the basis of changes in the color of gold nanoparticles, used as reporter probes. We have shown that the colors of gold nanoparticles with anionic protective groups on their surfaces shift from red to indigo/purple and then back to red in a range of cationic surfactant solutions in which concentrations vary from ...
Biochemical reaction networks in living cells usually involve reversible covalent modification of signaling molecules, such as protein phosphorylation. Under conditions of small molecule numbers, as is frequently the case in living cells, mass-action theory fails to describe the dynamics of such systems. Instead, the biochemical reactions must be treated as stochastic processes that intrinsical...
In this paper, the cyclic fatigue hysteresis loops of 2D woven SiC/SiC ceramic matrix composites (CMCs) at elevated temperatures in steam have been investigated. The interface slip between fibers and the matrix existing in matrix cracking modes 3 and 5, in which matrix cracking and interface debonding occurred in longitudinal yarns, is considered as the major reason for hysteresis loops of 2D w...
Mutations in GPSM2 cause Chudley-McCullough syndrome (CMCS), an autosomal recessive neurological disorder characterized by early-onset sensorineural deafness and brain anomalies. Here, we show that mutation of the mouse orthologue of GPSM2 affects actin-rich stereocilia elongation in auditory and vestibular hair cells, causing deafness and balance defects. The G-protein subunit Gαi3, a well-doc...
Two series of nucleolipids have been designed and synthesized, one with a varying chain length (the dT-Cn series) and the other incorporating an aromatic photo-responsive moiety at the molecular hydrophobic and hydrophilic interface (the P-dT-Cn series). Surface tension measurements revealed the variations of critical micelle concentrations (CMCs) with the alkyl chain length and the incorporati...
Abstract High levels of reactive oxygen species (ROS) in the wound surface are one reasons why chronic wounds difficult to heal. Using free radical scavengers reduce ROS and duration toxic effects can accelerate healing wounds. In this study, a novel edaravone (Ed)-loaded sodium alginate (SA)/carboxymethyl chitosan (CMCS) antioxidant composite film was prepared, physicochemical properties bioco...
There are many sets of information in the literature (e.g., papers, books and websites) about great achievements that expected for aerospace gas turbine engines by employment ceramic matrix composites (CMCs) thermally sprayed environmental barrier coatings (EBCs) their hot zones combustion chambers, vanes, shrouds, blades afterburners). Among these achievements, it is typically highlighted (i) ...
Abstract Edible coating CMCS/PVA/Cur and films were prepared using γ-irradiation to extend the shelf-life of sweet orange "Valencia" fruits. Water-soluble CMCS was synthesized by carboxymethylation chitosan. Extraction curcumin from turmeric powder conversion Cur-NPs 76–108 nm average size achieved. membranes via casting method gamma-irradiation technique. The chemical properties studied FTIR X...
Ceramic matrix composites made of silicon carbide fibers embedded in (SiC/SiC CMCs) are widely recognized as excellent replacements for denser superalloys such Nickel based super alloys high-temperature applications aero engines. During the manufacturing process with chemical vapour infiltration, large amount pores introduced CMC and their presence can have considerable impact on structural per...
