In this study, the thin-film composite membrane (TFCM) was fab­ricated for phenol–water separation using formaldehyde crosslinked polyvinyl­alcohol (PVA) coating on fly ash-fuller clay ceramic substrate. Thin film was created using 10 % PVA with diff... see more

Heparin, an active sulfate group material, grafted onto blend membrane citric acid cross-linked chitosan/poly (vinyl alcohol)-poly(ethylene glycol) (PVA-PEG) to improve the membrane properties. The physical tests shown that grafting reaction of citric aci... see more

The influence of cross-linking and membrane hydrophilicity on the transport rate had been studied using a membrane prepared from a mixture of chitosan/PVA cross-linked citric acid (PVA.cl.CA) for creatinine and urea transport. The optimum mole ratio of PV... see more

Noise pollution has become one of the four major pollution issues in the world and has drawn much attention recently. Controlling the sound source and using sound-absorbing materials reasonably is considered an effective way to reduce noise. Due to the hi... see more

The application of nanocomposite membranes for high organic wastewater treatment faces several problems such as impurities and low permeate flux. In this study, sulfonated ZnO nanoparticles were incorporated in the PSf membrane. SEM images reveal that sZn... see more

The application of composite membranes consisting of SiO2 from the volcanic ash of Mount Sinabung, TiO2, and PVA on a laboratory scale has been investigated to improve the Silau River’s water quality in Asahan Regency. The purpose of this study is to dete... see more

IPN hydrogels based on chemically modified poly(vinyl alcohol) (or PVA-Ma), with different degrees of substitution (DS), and poly(N-isopropylacrylamide) (or PNIPAAm) were obtained and characterized through measures of LCST, swelling ratio and mechani... see more

Direct Methanol fuel Cell (DMFC) merupakan teknologi sel bahan bakar yang mengubah energi kimia menjadi energi listrik secara langsung. Polieter eter keton tersulfonasi (sPEEK) berpotensi sebagai proton exchange membrane. Modifikasi sPEEK dengan poli vini... see more

The types of wound dressing will affect wound healing processes. The membrane is one of the potential wound dressing that can maintain the moisture of the wound surface. The eel extract as an active ingredient could be added to the membrane formula to acc... see more
