Porous geopolymers have drawn widespread attention owing to the flexibility of production processes and diversity their structural properties. This paper first investigates describes key parameters for fabrication ceramic foam based on a geopolymer mixture by impregnation using replica technique. The influence viscosity total porosity, pore size mechanical strength leucite foams is evaluated. accelerated solidification step at 70 °C was investigated time-dependent viscoelastic such as tan δ,...
Abstract A gas chromatography/mass spectrometry (GC/MS) method for the determination of 11 selected acidic pharmaceuticals in sewage influent and effluent at trace levels has been developed. The drugs studied were salicylic acid, clofibric ibuprofen, acetaminophen, gemfibrozil, fenoprofen, naproxen, ketoprofen, diclofenac, fenofibrate, indomethacin, which are commonly used as analgesic/anti-inflammatory agents or lipid regulators. antibacterial agent triclosan was also included this study....
Vanadium redox flow battery (VRFB) is a potential electrochemical energy storage solution for residential accumulation and grid stabilization. Long-term durability, non-flammability high overall efficiency represent the main advantages of technology. The ion-exchange membrane, an essential component stack, largely responsible capacity losses caused by asymmetric cross-over vanadium ions solvent. To mitigate these losses, we developed mathematical model VRFB single-cell both cation-exchange...
A program package is presented named CAPCAL that provides a method for calculation of the 3-D electric field distribution due to multilayer metallization advanced VLSI (very large-scale integration) integrated circuits. The underlying physics and numerical modeling techniques used by are described. finite-difference together with multigrid solver permit easy handling full portability. Example capacitance calculations structures typical wiring memory cell. influence line spacing permittivity...
A field study of industrial organic contaminant uptake, in particular PCB by growing crops was conducted during 1990 at the St. David Coal Refuse Pile Reclamation Site, Fulton County, Illinois. The site had received one-time applications 1987 785, 1570 and 3360 Mg ha−1 dry wt. Chicago municipal sewage sludge. Corn (Zea mays L.), cabbage (Brassica oleracea capitata carrot (Daucus carota L.) were grown on sludge treatments soil (i.e., treated coal refuse) plant samples analyzed. Mean...
Catalytic monolith filters with a honeycomb structure represent key component of modern automotive exhaust gas aftertreatment systems. In this paper, we present and validate multiscale modeling methodology for the prediction filter pressure loss depending on channel geometry as well microscopic wall including catalytic coating. The approach is based combination 3D pore-scale model flow through reconstructed from X-ray tomography 1D+1D channels. Several cordierite SiC samples varying...
A new two-dimensional process modeling program written in Fortran is described. For the first time, this allows simulation of all important processing steps occurring typical sequences involved fabrication integrated circuits such as doping, oxidation, lithography, etching, and layer deposition. The possesses a modular structure to allow for easy changing improvement models well mathematical procedures. menu driven make it use non-experts readily usable with different computer systems.
Digestion of municipal wastewater biosolids is a necessary prerequisite to their beneficial use in land application, order protect public health and the receiving environment. In this study, 13 pharmaceuticals personal care products (PPCPs), 11 musks, 17 polybrominated diphenyl ethers were analyzed 84 samples including primary sludge, waste activated digested biosolids, dewatered dewatering centrate or filtrate collected from five treatment plants with aerobic anaerobic digestion. Aerobic...
Redox flow batteries of various chemistries are potential electrochemical energy storages for residential accumulation and grid stabilization. Decoupled power capacity represent the main advantages technology. The key component battery, carbon felt electrode, does not participate in reaction directly, but it provides active sites electroactive ions. In addition, electrode contributes to battery stack polarization through charge transfer, ohmic mass transport resistances increases hydraulic...
The occurrence of human as well veterinary drug residues in surface water is caused by their insufficient removal ability from wastewater. Drug disturb the natural balance ecosystem, have a negative effect on non-target organisms and pose significant risk for health. main aim this study was to determine concentration eight drugs group sulfonamides (sulfathiazole, sulfadiazine, sulfamethazine, sulfamethoxazole, sulfadimethoxine, sulfadoxine, sulfamerazine, sulfachlorpyridazine), four...
