This project studies the synthesis process of 2-D nanostructure of inorganic materials. This project studies the ZnO thin layer deposition on a commercial grade paper using Atomic Layer Deposition (ALD) technique and its effectiveness of reducing water permeability. The experiment utilizes a commercial grade blue ink for the testing of the permeability. The purpose of the experiment is to succe...

Ammonium nitrate/fuel oil (ANFO) is one of the most commonly used materials for improvised explosive devices (IEDs). Stand-off ANFO vapour sensors that are small, inexpensive, and easy to use will allow detection IEDs in security humanitarian settings. Concealment main challenges IED increases need highly sensitive sensors. Here, percolation networks polypyrrole (PPy) detect buried under variou...

Study on the technology that sidetracking horizontal wells with ultra-short radius to select boundary layer has certain practical meaning. But recently this kind of research, especially the study on sidetracking position for horizontal well, is less or even none. In this paper, on the basis of the potential superposition method and the equivalent flowing resistance method, the cumulative oil pr...

We analyze recent experiments that show that a cylinder can be suspended in a stable position by placing it on a vertically moving belt that is covered by a thin layer of very viscous oil. The weight of the cylinder is supported by viscous forces in the fluid layer, and the cylinder rotates with respect to its axis in the direction of the belt motion. We propose a simple model for stable suspen...

In this paper we assume determination of pseudo-viscosity coefficients of visco-elastic non-Newtonian fluid flow directly near the cooperating micro-bearing surface. We show the constitutive stress-strain dependencies of nonNewtonian visco-elastic media with regard to the content of addition of nano-particles. The greater content of nano-particles and influences of superficial layer of cooperat...

The synthesis of tailormade thin-film composite (TFC) nanofiltration (NF) membranes produced by interfacial polymerization is presented for the separation unspent (MEA-triazine) and spent (DTZ) H2S scavengers obtained from an oil gas wastewater offshore installation in North Sea. physicochemical properties, thermal stability, hydrophilicity synthesized TFC were investigated using SEM, FTIR, XRD...

The complex physics of multiphase flow in porous media are usually modeled at the field scale using Darcy-type formulations. The key descriptors of such models are the relative permeabilities to each of the flowing phases. It is well known that, whenever the fluid saturations undergo a cyclic process, relative permeabilities display hysteresis effects. In this paper, we investigate hysteresis i...

Generalization of the release process through the wax matrix layer was examined by use of a reservoir device tablet. The wax matrix layer of the reservoir device tablet was prepared from a physical mixture of lactose and hydrogenated castor oil to simplify the release properties. Release through the wax matrix layer showed zero-order kinetics in a steady state after a given lag time, and could ...
