In this study, polyphenylsulfone (PPSU) hollow fiber membrane was fabricated via a wet spinning method with the addition of ethylene glycol (EG) in the range of 0-10 wt% as the additive. The EG was added to improve the membrane pore formation and interconnectivity for better membrane contactor performance in extracting and removing the free fatty acid (FFA) from crude palm oil (CPO). Four diffe...

An electrochemical reactor can be used to purify flue gasses. Such a reactor can be a multilayer structure consisting of alternating layers of porous electrodes and electrolytes (a porous cell stack). In this work optimization of such a unit has been done by changing the pore former composition and the electrode powder pre-treatment. The effect on permeability, mechanical strength and electroch...

Process conditions for the fabrication of porous uranium oxide microspheres prepared via internal gelation were assessed. To improve application infiltration, microstructural parameters such as density, porosity and specific surface area Specifically, effect calcination temperature use pore-formers was studied. Accessible levels around 20% obtained after at 773 K or 823 K, without a pore-former...

Microporous osmotic tablet of diltiazem hydrochloride was developed for colon targeting. These prepared microporous osmotic pump tablet did not require laser drilling to deliver the drug to the specific site of action. The tablets were prepared by wet granulation method. The prepared tablets were coated with microporous semipermeable membrane and enteric polymer using conventional pan coating p...

We consider a general double pulsed field gradient experiment with arbitrary experimental parameters and calculate an exact expression for the NMR signal attenuation from restricted geometries, which is valid at long wavelengths, i.e., when the product of the gyromagnetic ratio of the spins, the pulsed gradients' duration, and their magnitude is small compared to the reciprocal of the pore size...

Enhanced Geothermal Systems (EGS) are engineered reservoirs created to economically extract heat from low permeability and/or porosity geothermal resources. Existing geochemical reactive transport models for such systems lack essential data on the structure of the pore systems in geothermal reservoirs, and how they evolve in the relevant ranges of temperature, pressure, composition, and length ...

This study describes the porosity and particle size effects of rice husk pore former on diametral tensile strength porous alumina (Al2O3) ceramics. Porous Al2O3 ceramics with high sufficient were successfully prepared by pore-forming agent method using (RH) as according to sample formulation Al2O3-xRHy (where ‘x’ denotes range in µm ‘y’ percent weight content (wt%) RH). The thermogravimetric an...
