Superhydrophobic and transparent coatings are deposited onto paper by spraying alcohol suspensions of SiO(2) nanoparticles. Superhydrophobicity depends on the aggregation states nanoparticles, which determined type used in suspensions. The superhydrophobicity is maintained after touching with a bare finger.

Superhydrophobic coatings were prepared by spraying a pigment nanoparticle suspension. By changing the type of nanoparticles, colors coating could be controlled. The particle size pigments, which determines surface structure coatings, played an important role in exhibiting superhydrophobicity. spray-coating process is applicable to variety materials (e.g., copper, glass, paper, coiled wire, and tied thread), superhydrophobicity was repairable.

An organic hydride system based on hydrogenation/dehydrogenation of toluene (TL)/methylcyclohexane (MCH) has been studied as a hydrogen storage technology. Electrohydrogenation TL to MCH using proton exchange membrane (PEM) electrolyzer is proposed candidate for the hydrogenation in system. Recently, we reported that Ketjenblack-supported Ru-Ir alloy (Ru-Ir/KB) cathode was effective reaction; however, electrohydrogenation mechanisms and catalyses Ru Ir have unclear. In this paper, detailed...

Abstract Three-dimensionally ordered macroporous (3DOM) materials of spinel-type MFe2O4 (M = Zn, Ni, ZnxNi1−x (x 0.2–0.8), and Co) mixed iron oxides were prepared in excellent yields by using a colloidal crystal templating method. Mixed metal nitrates dissolved an ethylene glycol (EG)–methanol solvent penetrated into the void template poly(methyl methacrylate) (PMMA) spheres. During calcination process, reacted with converted glyoxylate derivatives voids crystals before polymer sphere was...

Methyl formate (MF) is an important intermediate in the production of essential chemicals such as formic acid chemical industry. Although MF currently synthesized via liquid-phase carbonylation methanol, this process has certain problems (e.g., catalyst deactivation). In regard, alternative processes for have been extensively examined, and formation with a high selectivity rate at mild reaction conditions remains critical goal research. Here, we demonstrated synthesis direct electrolysis...

Abstract Dry reforming of methane (DRM) is a promising catalytic process for converting greenhouse gases (CH 4 and CO 2 ) into syngas (CO H ). This study investigates DRM under moderate conditions (550 °C) using supported low‐loading (0.05 wt%) metal (M) catalysts (M = Rh, Ru, Pt, Pd, Ir, Au, Ni).
