Molybdenum-zeolite catalysts always suffer from severe carbon deposition and rapid deactivation in the methane dehydroaromatization (MDA) process. Herein, we present a strategy that controls spatial distance between Mo species HMCM-22 zeolite over Mo/HMCM-22 catalysts, to inhibit deposition. Our characterization analyses demonstrate possess same active components, but plays key role determining...

The adoption of metal additive manufacturing into the production passive microwave components is still in its relative infancy. However, it increasing interest due to offer geometrical design freedom and significant weight reduction. electrical properties manufactured are inferior traditional techniques owing poor surface finish, especially on overhanging surfaces, which unavoidable three-dimen...

Electrochemical composite coatings allow successfully solving many practical problems of surface-hardening structural parts and their tooling components, as well renewing fast-wearing components. chromium-matrix are used to enhance the thermal wear resistance steel articles operating in friction conditions under increased temperatures, but low shock loads. This paper presents results obtained f...

BACKGROUND: Manual wheelchair users are at a high risk of repetitive strain injuries, carpal tunnel syndrome, and rotator cuff tears due to propelling their for mobility. Rolling resistance (RR) is one the key forces that leads increased propulsion injuries. OBJECTIVE: To better understand factors contributing RR, we iteratively designed, developed, validated drum-based testing machine test met...

Gram positive pathogens mainly Staphylococcus aureus, Enterococcus and Coagulase Negative Staphylococcus are hospital acquired (HA) pathogens. HA strains are usually multidrug resistant (MDR). Monitoring of these strains is essential in order to control their spread in the hospital environment and transmission to the community. The objectives were to assess the prevalence of Gram positive patho...
