Optoelectronic tweezers enables parallel manipulation of individual single cells using optical addressing and optically induced dielectrophoretic force. This provides a useful platform for performing a variety of biological functions, such as cell manipulation, cell sorting, and cell electroporation. However, in order to obtain more reliable cellular manipulation, especially of adherent mammali...

A novel high throughput method for synthesis and screening of customized protein-resistant surfaces was developed. This method is an inexpensive, fast, reproducible and scalable approach to synthesize and screen protein-resistant surfaces appropriate for a specific feed. The method is illustrated here by combining a high throughput platform (HTP) approach together with our patented photo-induce...

Matsu To reduce membrane fouling of reverse osmosis (RO) membrane, we adopted layer-by-layer (LbL) assembly. LbL assembly has received attention as a means of preparing ultrathin layers of composite membrane...

In membrane processes, various agents are used to enhance, protect, and recover membrane performance. Applying these agents in membrane modification could potentially be considered as a simple method to improve membrane performance without additional process. Citric acid (CI) and sodium bisulfite (SB) are two chemicals that are widely used in membrane feed water pretreatment and cleaning proces...

the gas separation performance of commercial ceramic titania and hybrid silica (hybsi®) membranes was assessed using the gas permeation and permporometry methods. results indicated that the hybsi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. these membranes have high h2 selectivity, which increases significantly with temperatu...

Photocatalytic TiO2-PVDF/PMMA nano-composites flat sheet membranes were fabricated by phase inversion and then employed in a crossflow filtration pilot to remove model pollutants of various sizes charge from aqueous solution. The dope solution contained mixture PVDF PMMA as polymers, polyethylene glycol (PEG) polyvinylpyrrolidone (PVP) additives, triethyl phosphate (TEP) green solvent TiO2 immo...
