The ever-increasing demand for energy in our society calls for more efficient andsustainable recovery of fossil fuels. Enhanced Oil Recovery (EOR) deals with im-proving the recovery of oil from reservoirs. It encompasses not only the large-scaleengineering enterprise, but also the fundamental understanding and discovery ofthe relevant physicochemical processes. The motivation fo...

Micellar-enhanced ultrafiltration (MEUF) of zinc ions (Zn2+) from aqueous solutions using single anionic surfactant sodium dodecyl sulphate (SDS) at low critical micelle concentrations (cmc) (0.2×cmc – 3×cmc) was investigated. When the initial SDS concentration was below the cmc, unexpectedly high rejection (97.5%) was obtained due to concentration polarisation occurring near the membrane-solut...

The monomer analog of a common water-soluble charged macromolecule shows surface tilt and cooperative adsorption that would be expected for larger surfactant molecules—the small organic ion behaves as an embryonic surfactant. Yet the organic ion competes with inorganic ions (Na, Mg, etc.) for access to the surface, and therefore its tilt increases with the size of the competing coion. Similar o...

the effects of coatingtreatments (waxand plasticbags) combined with methylsalicylate on the fruit quality and chilling injury of moro blood orange were studied during storage. treated fruits were kept in storage for 80 days at 5 oc and 90-95% relative humidity. some characteristics such as pulp and skin total phenolics, antioxidant capacity, total anthocyanin, lipid peroxidation, and the chilli...

The ability of natural clinoptilolite and its modified forms were studied for removal of PAHs from n-paraffin. Surfactant modified zeolite (SMZ) was obtained by modifying clinoptilolite with hexadecyltrimethylammonium ion. Homoionic forms of zeolite were obtained by ion exchange process using inorganic salts of desirable cations (e.g. Ag+, Fe3+…). Nat...

A theoretical investigation associated with obliquely propagating ion-acoustic shock waves (IASHWs) in a three-component magnetized plasma having inertialess non-extensive electrons, inertial warm positive and negative ions has been performed. Burgers equation is derived by employing the reductive perturbation method. Our model supports both structures under consideration of electrons. It found...

The computer simulation program of a practical scale reverse electrodialysis process has been developed based on the program for saline water electrodialysis. The program is applied to compute the performance of an industrial-scale reverse electrodialysis stack (effective membrane area S = 1 m × 1 m = 1 m2, cell pair number N = 300 pairs). The stack operatingconditions are optimized. Seaw...
