A new metal borohydride ammoniate (MBA), Zr(BH4)4·8NH3, was synthesized via ammoniation of the Zr(BH4)4 crystal. Zr(BH4)4·8NH3 has a distinctive structure and the highest coordination number of NH3 groups among all the known MBAs. This compound could quickly dehydrogenate at 130 °C, enabling it a potential hydrogen storage material.

A new type of cascaded series feed beamforming networks (BFNs) is introduced. The network architecture is based on a dualseries Nolen matrix topology. It is able to produce tapered output amplitude distributions from N × N configurations. The general concept, analysis and systematic design of the BFNs are given. The networks are designed and intended to be used mainly for low Sidelobe Level (SL...

Abstract. Environmental pollution that is often encountered in daily life comes from laundry waste. Laundry waste includes pollutants or substances pollute the environment because it there a substance called linear alkylbenzene sulphonate (LAS). LAS detergent classified as hard to brake down by microorganisms (non-biodegradable) so can cause environmental pollution. One method used wastewater t...

Abstract This study aimed to determine the influence of vehicular emissions and meteorological factors on level surfactants in urban atmospheric aerosol from Kuala Lumpur city center, Malaysia. Aerosol samples were collected using a high-volume sampler equipped with cascade impactor separate fine mode (< 1.5 µm) coarse (> particles. Besides, exhaust particulate matter various diesel petro...
