CONCURRENT EVAPORATING SPRAY JETS IN DILUTE GAS-SOLIDS PIPE FLOWS by Xiaohua Wang Evaporating spray jets into gas-solids suspensions are encountered in many industrial applications. The rapid evaporation of spray jets has significant effects on the gas-solids mixing near the jet nozzle regions, including non-uniform solids concentration dilution, gas/solids temperature reduction, and gas/solids...

The synthesis, structural characterization, optical spectroscopy, and electronic characterization of close packed solids prepared from CdSe QD samples tunable in size from 17 to 150 A in diameter (a<4.5%) are presented. We control the deposition of 3D QD glasses and superlattices by tailoring the solvent composition used to deposit the QD solids. We use high resolution scanning and transmission...

Multicomponent pharmaceutical solids is a hot topic that brings together the knowledge of crystal engineering and need to achieve novel effective drugs at lower costs for industry [...]

Solids control equipment at the rig site is used to remove rock cuttings or low-gravity solids (LGS) from drilling fluids to allow the fluid to return to the active system in a re-usable condition. Typical equipment, such as shakers and centrifuges, remove LGS particles greater than 5-7 microns. Build up of finer solids in the fluid can create problems for efficient drilling such as drillpipe s...

Metalloporphyrins are exceedingly useful building blocks for the design and synthesis of molecularly based solids. The use of hydrogen bonding or metal ion coordination provides a wide range of framework solids. Using various polyfunctionalized porphyrins, we have created porous solids that are thermally robust and that retain their internal porosity upon loss of solvates. Their pore dimensions...

We propose a method for handling elastic solids in SPH fluids. Our approach samples triangulated surfaces of solids using boundary particles. To prevent fluid particle tunneling in case of large expansions, additional boundary particles are adaptively generated to prevent gaps and undesired leakage. Furthermore, as an object compresses, particles are adaptively removed to avoid unnecessary comp...

The aim of this study was the increasing of leachate quality using integrated membrane bioreactor (MBR). The reactor was fed with treated leachate with overall 70-1360 mg/l chemical oxygen demand (COD). The analysis of COD, biochemical oxygen demand (BOD5), total suspended solids (TSS), and total dissolved solids (TDS) were performed in feed and filtrate, whenever the system reached steady stat...

Although all solids show quantum effects to some degree, solids made from the lightest elements (He, He, H2, D2..) have special properties of purely quantum mechanical origin that set them apart. For this reason they are known as quantum crystals (1) and the aim of this set of lectures is to discuss recent ideas on tunneling in these solids and the current interest in testing the models for tun...
