Benzimidazoles are among the most important nitrogen-containing heterocyclic compounds that have many pharmaceutical applications; including, antitumor, anticancer, anticorrosive, antibacterial, irritant and enzymatic interceptors. In this research, the synthesis of benzimidazoles using o-phenylenediamine and aldehyde derivatives in the presence of the nano montemurillonite in solvent-...

Flexible electrochemical energy storage devices have attracted extensive attention as promising power sources for the ever-growing field of flexible and wearable electronic products. However, the rational design of a novel electrode structure with a good flexibility, high capacity, fast charge-discharge rate and long cycling lifetimes remains a long-standing challenge for developing next-genera...

By one-step pyrolysis of a unique "cage-in-cage" cobalt metal-organic framework, nitrogen-doped carbon cubes embedded with numerous metallic Co nanoparticles were obtained. A considerable amount of Co particles was encapsulated in thin carbon shells and formed the core-shell-like Co@C structure. With about 60 wt% Co particles in the prepared sample, the nanocomposites of Co nanoparticles and ni...

The energetic igniters through integrating B/Ti nano-multilayers on tantalum nitride (TaN) ignition bridge are designed and fabricated. The X-ray diffraction (XRD) and temperature coefficient of resistance (TCR) results show that nitrogen content has a great influence on the crystalline structure and TCR. TaN films under nitrogen ratio of 0.99 % exhibit a near-zero TCR value of approximately 10...

Precision droplet manufacturing (PDM) is a process that builds complex 3D parts one nano-liter molten metal droplet at a time from a CAD file without the need for tooling. One method to control the droplet temperature when it arrives at the target is to heat the droplets in-flight. This note describes such a heater that uses helium and nitrogen as the convective heat transfer medium. Heating ra...

Benzimidazoles are among the most important nitrogen-containing heterocyclic compounds that have many pharmaceutical applications, including antitumor, anticancer, anticorrosive, antibacterial, irritant and enzymatic interceptors. In this research, the synthesis of benzimidazoles by using o-phenylenediamine and aldehyde derivatives in the presence of the nano montemurillonite in solvent-free an...

Abstract Background The use of hazardous and toxic chemical material has become limited by the green synthesis nano-particles (NPs) from plants other living organisms. In current study, a new nano-fertilizer was synthesized Paulownia tomentosa leaves then its effectiveness in alleviation drought stress Ocimum basilicum investigated. Five concentrations (0, 50, 70, 90 110 ppm) at three irrigatio...
