The effect of Cu on cobalt/titania nanorod (Co/TNR) catalysts for the promotion carbon monoxide (CO) hydrogenation to hydrocarbons was investigated. Varying amounts (1.5–6.0 wt%) were loaded onto base Co/TNR catalyst using deposition–precipitation method. Characterization by X-ray diffraction (XRD) revealed that particles well dispersed over catalysts. Characterizations temperature-programmed d...


 Bahan baja tahan karat (stainless steel) banyak digunakan dalam industri rumah tangga maupun militer, dan juga nuklir. dibagi menjadi lima tipe yaitu austenite, ferite, martensite, duplex precipitation hardening. Baja feritik merupakan alternatif yang menarik produksi kendaraan karena sifat ketahanan terhadap laju korosi. Logam tidak sejenis mempunyai karakteristik berbeda satu dengan la...

In this paper, we reported a theoretical study of novel Surface plasmon resonance (SPR) biosensor composed BK7 prism, gold (Au)/silver (Ag) bimetallic layer, silicon and two-dimensional (2D) materials. The layer combines the advantages Au Ag high refractive index enhances electric field on surface sensor, so that sensor has better overall performance in terms sensitivity figure merit (FOM). Com...
