The development of thin-film composite membranes has gained more importance as they exhibit higher permeability, solute rejection and improved antifouling behavior. incorporation hydrophilic nanomaterials within the thin film reported to effectively increase hydrophilicity improve membrane performance. In this study novel nanofiltration were prepared by interfacial polymerization trimesoyl chlo...

The fouling of ships and propellers results in a reduction of speed, increased fuel consumption, and consequently, losses of both time and money. The previous studies found that a speed reduction of 0.03 knots would occur due to increased friction resulting from 10μm increase in surface roughness. This would increase fuel consumption by 1%, energy savings can then be easily converted into emiss...

Benthic marine organisms are constantly exposed to fouling, which is harmful to most host species. Thus, the production of secondary metabolites containing antifouling properties is an important ecological advantage for sessile organisms and may also provide leading compounds for the development of antifouling paints. High antifouling potential of sponges has been demonstrated in the Indian and...

Oil–in–water emulsion separation is a challenging process in industries due to the large volumes of emulsified oil produced. Membrane technology has become more important treatment its high efficiency and straightforward operational procedure. Up now, microfiltration ultrafiltration are most utilized membrane processes for oil-in-water separation. However, deals with several problems. The prese...

One new dimeric diterpenoid, 8(14)-enyl-pimar-2'(3')-en-4'(18')-en-15'(16')-endolabr- 16,15,2',3'-oxoan-16-one (1) and five known terpenoids: Tagalsin C (2), Tagalsin I (3), lup-20(29)-ene-3β,28-diol (4), 3-oxolup-20(29)-en-28-oic acid (5) and 28-hydroxylup- 20(29)-en-3-one (6) were isolated from the roots of the mangrove plant Ceriops tagal. Their structures and relative stereochemistry were e...

Abstract Oil and water separation is a significant challenge due to the rapid discharge of oily wastewater. Special wettable membranes have received substantial consideration in emulsified oil/water separation. Here, superhydrophobic octadecyl-functionalized crosslinked graphene-oxide-grafted ceramic membrane (R18-CLGO-N-CM) was designed separate water-in-oil emulsions. The selective layer eval...

Due to their extraordinary prospective uses, particularly in the areas of oil–water separation, underwater superoleophobic materials have gained increasing attention. Thus, artificial nacre has become an attractive candidate for separation due its superhydrophilicity and superoleophobicity properties. Synthesized successfully achieved a high mechanical strength that is close or even surpasses n...

In this study, RuO2-embedded PES membrane was prepared and it used for protein separation. The antifouling properties of the fabricated composite membranes were also investigated using bovine serum albumin (BSA) as solution. mean roughness increased proportionally by introducing RuO2 particles. porosity higher than that pristine membrane. On other hand, has smaller average pore size after addit...
