El presente trabajo se centra en la caracterización de una matriz polimérica de alcohol polivinílico (PVA), preparada a partir de la dispersión de un complejo mononuclear organometálico a base de europio trivalente, Eu3+. Los complejos de Eu3+ se sintetiz... see more

Penelitian tentang baterai ion lithium sebagai sistem penyimpanan energi berkembang begitu pesat. Pada baterai ion lithium, salah satu bagian utama adalah anoda yang terdiri atas material LiTi2(PO4)3. Maka, penelitian ini bertujuan untuk mengetahui pengar... see more

Pemanfaatan rumput laut cokelat khususnya didaerah Madura dimana lokasinya yang dekat dengan Surabaya, hanya sebatas untuk makanan warga sekitar. Hal ini menjadi acuan untuk mengembangkan dan meningkatkan potensi rumput laut cokelat dengan mengekstrak sal... 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

In this study, pure polymer blend (PVA:PVP) film and salt (CdCl2·H2O) reinforced polymer blend films were prepared at different weight ratios (10 wt%, 20 wt%, 40 wt%) using the casting method. The effect of the salt weight ratio on the dielectric properti... see more
