The desire to mitigate climate change due to greenhouse gas emissions has led to the exploration of plant fibers as alternative materials for various industrial applications, sound absorption inclusive. In this investigation, sound absorption properties of Antiaris toxicaria barkcloth, and the thermal insulation properties of the barkcloth epoxy laminar composites were characterized. Theoretical sound absorption models were utilized to validate the experimental data and the empirical models were in agreement with experimental data. The lowest thermal conductivity was achieved by the Antiaris toxicaria epoxy composites. 相似文献

Effect of Ca2+ on radiation induced lipid peroxidation of ghost membranes prepared from mice erythrocytes was studied at a dose rate 1.01 Gy/s. Ca2+ provided significant protection against lipid peroxidation in concentration dependent manner. Ca2+ is known to modify membrane dynamics and might be the reason for inhibition of lipid peroxidation. Post-irradiation treatment with Ca2+ also resulted in significant inhibition of lipid peroxidation. The diminition of protective effect in presence of A23187 suggests that the extracellular pool of Ca2+ may provide protection against the effect of radiation on plasma membrane. 相似文献

A new regioselective approach to the synthesis of α-aryl enones is reported. This represents an important application of the Kuwajima-Urabe protocol toward the synthesis of this simple albeit complex functional array. Several α-aryl enones were synthesized by the palladium catalyzed arylation of triethylsilylenol ethers of enones with high regioselectivity and broad scope, utilizing sterically encumbered electron-rich phosphine ligands to drive the reaction. 相似文献

The occurrence of room temperature ferromagnetism is demonstrated in pulsed laser deposited thin films of Sn(1-x)Co(x)O(2-delta) (x<0.3). Interestingly, films of Sn(0.95)Co(0.05)O(2-delta) grown on R-plane sapphire not only exhibit ferromagnetism with a Curie temperature close to 650 K, but also a giant magnetic moment of 7.5+/-0.5 micro(B)/Co, not yet reported in any diluted magnetic semiconductor system. The films are semiconducting and optically highly transparent. 相似文献

The phenomenon of particulate loss (elutriation) from fluidized beds is important in many industrial processes. Results reported in Kale & Eaton (1984a) showed that very-wide-angle diffusers located in the freeboard above a fluidized bed substantially reduce elutriation—a result that was contrary to intuition. The present experiment was designed to explain these results. The same fluidized bed apparatus (Kale & Eaton 1984a) was used—150 mm square in cross section with a variable-angle diffuser in the freeboard region. Glass beads (nominally 50–100 μm in diameter) were fluidized by air at atmospheric pressure in the bubbling regime. Gas-phase velocity measurements were made using a single-component laser-Doppler anemometer. Four diffuser configurations (0, 20, 40 and 60° full opening angle) were studied. One set of measurements was made with the bed in place and a second set with the bed material removed. The flow structure was drastically altered by the presence of the fluidized bed below the diffuser. The single-phase flow was separated in the diffuser for the 20, 40 and 60° cases. However, the flow did not separate in the presence of the bed, and the peak fluid velocities were lower than those in the separated flow. This behavior is responsible for the decrease in the elutriation rate with increasing diffuser opening angle. A simple analysis suggests that suspended particles in the diffuser flow are responsible for the change in the flow structure. Momentum loss from the gas to the suspended particles reduces the pressure gradient, thereby eliminating the tendency to separate. 相似文献

EMF measurements in water at 25°C have been made using surfactant ion and counterion electrodes on two homologous series of long chain surfactants, the sodium alkylsulfates (R=n-C8H17 to n-C14H29) and the alkyltrimethylammonium bromides (R=C10H21 to C16H33). The data show evidence of association below the critical micelle concentration (CMC) but not of micelle ordering due to coulombic repulsion above this concentration. 相似文献
