Pressure retarded osmosis has the potential to produce renewable energy from natural salinity gradients. This work presents the fabrication of thin-film composite membranes customized for high performance in pressure retarded osmosis. We also present the development of a theoretical model to predict the water flux in pressure retarded osmosis, from which we can predict the power density that ca...

Purpose: To measure the extent of solubility of the lipophilic drug, aceclofenac, in 13 oils as well as its in vitro permeability from these oils in order to develop optimized topical microemulsion and microemulsion-based gel for improved bioavailability. Methods: UV spectrophotometeric method was used at the wavelength of 276 nm to measure the dissolved quantity of aceclofenac in each of the o...

We describe a poreto reservoir-scale investigation of wettability variation and its impact on waterflooding. We use a three-dimensional pore-scale network model of a Berea sandstone to predict relative permeability and capillary pressure hysteresis. We successfully predict experimentally measured relative permeability data for the water-wet case, and demonstrate that the model captures experime...

To take capillary effect into account, a series of primary drainage experiments of water by a sample oil fluid have been studied. The experiments performed under different low flow rates on a horizontal glass type micromodel as a model of porous media. Based on conventional macroscopic flow equations, the relative permeabilities and capillary pressure are determined by parameter estimation tech...

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...

The permeability of the swimbladder to gas was measured as the conductance to oxygen in seven species of fish. The low over-all conductance resides in the low diffusion constant, K, of the middle layer of the wall (submucosa) while the outer and inner layers (tunica externa and mucosa) have diffusion constants similar to other vertebrate tissues. The low diffusion constant is due to a low diffu...
