A long chain insect pheromone for subterranean termites, LC (Lignoceric Acid), was intercalated into the inorganic interlayer, ZLH (Zinc Layered Hydroxide), resulting in the formation of a new nanohybrid, labelled as LCN (Lignocerate Nanohybrid). The formation of this inorganic-organic structure nanohybrid was synthesized by the co-precipitation method using ZnO (Zinc Oxide) as the starting material. The PXRD (Powder X-Ray Diffraction) results confirmed the intercalation process although the diffraction patterns of the resultant nanohybrid and the unbound pheromone were fairly similar but both have different basal spacings values. The FTIR (Fourier Transform Infrared) profiles and the chemical composition test supported the intercalation process with the percentage loading of LC into ZLH calculated to be 85%. The thermal stability of the free anion, LC was enhanced when it was transformed into LCN, increasing from 257 °C to 352 °C. The release of LC from the nanohybrid behaved in a sustained manner, governed by the pseudo-second order kinetic model with higher release of LC in sodium carbonate solution than the pH aqueous media. The synthesized nanohybrid was found to be safe for plant germination when the two seed types were successfully germinated in all the tested nanohybrid concentrations. However, the percentage seed germination and the radical seed length from the nanohybrid showed lower values compared to its counterpart anion, LC.

Mechanical Properties and Radiation Analysis of Aluminium Matrix Reinforced with Boron Carbide Composites

This work presents the study of lightweight aluminium matrix reinforced with boron carbide composites fabricated via powder metallurgy technology as shielding materials for neutron radiation. The attenuation experiments on the samples were carried out using neutron source, spontaneous fission neutron source Americium 241/Beryllium (241Am/Be). The scanning electron microscopy (SEM) micrographs revealed a relatively uniform distribution of B4C particles and good interfacial integrity between matrix and B4C particles. Hardness values increase with increase in volume fraction of reinforcement. The results show that the samples have the radiation shielding effects and dependence of the attenuation of neutrons on B4C percentage in composites. It can be concluded that Al/B4C composites could be a candidate material for neutron shielding application.

The incidence of dengue in Malaysia has shown an increasing trend since the year 2000. Vector control is the primary approach for dengue control in Malaysia. There is an urgent need for new or modified approaches such as the residual spraying on the outer walls that can potentially last long enough to control the Aedes population, particularly in the outbreak-prone areas. In this field study, we conducted outdoor residual spraying (ORS) using a newly formulated polymer-enhanced suspension concentrate (SC-PE) of deltamethrin. The objectives of this study were to evaluate the efficacy of ORS using deltamethrin SC-PE and its effect on wild Aedes populations and to assess its residual bio-efficacy on painted cement walls against the pyrethroid-susceptible strains of laboratory-reared Aedes mosquitoes. Three rounds of spraying in a four-month cycle were conducted between 2014 and 2015 in four residential areas (low-rise and high-rise housing types) in Hulu Langat, Selangor. The bio-efficacy of the insecticide was evaluated by assessing its impact on vector population using ovitrap surveillance. Standard WHO wall deposit bioassay was adapted to determine bio-efficacy of deltamethrin, i.e. post 30 min knockdown and post 24 h mortality after exposure. During the treatment period, we observed significant reductions in the population of Ae. albopictus in the sprayed low-rise housing in both semi-indoor and outdoor environments, while in the high-rise housing, there was also a significant decline in Ae. aegypti population in the semi-indoor environment. The evaluation of the residual bio-efficacy of deltamethrin SC-PE against laboratory-reared Aedes mosquitoes showed that the insecticide lasted longer in the high-rise housing compared to the low-rise housing with >80% mortality achieved continuously for 16 weeks. We provide initial evidence on residual efficacy of deltamethrin SC-PE in reducing Aedes population size in the low-rise and high-rise housing. Our results showed tha
