Poly (lactic acid) (PLA) which is a product of condensation polymerization of lactic acid, is a biodegradable polyester that has been studied as an alternative material to petroleum based polymers for many industrial applications due to its high strength, thermoplasticity, transparency and fabric ability. In addition, it can be synthesized by a fermentation process using carbohydrate from plants such as tapioca, corn or rice. However, its uses are restricted to certain area of applications due to its brittleness and low flexibility. One of the attempts made to reduce this polymer brittleness and increase its flexibility to widen the scope of the applications is to convert it into nanocomposites by blending it with a small quantity of nanomaterials. We have studied the preparation of PLA nanocomposites using synthetic and natural clays as their additives and characterization using various instruments. In order to improve the clay compatibility with the matrix, the inorganic materials were first modified using large organic molecules. In this lecture, use of an x-ray diffraction analysis for the PLA clay nanocomposite characterization is discussed. This analysis technique can be used as a tool to determine the clay layers’ arrangement before and after its modification, as well as their arrangements in the synthesized nanocomposites.

Natural fiber reinforced composites are essential for the growth of polymer composite technology. The key goal of this study is to utilize the natural bamboo Gigantochloa scortechinii, which is obtained in Melaka, Malaysia. In this study, the mechanical properties of woven bamboo, epoxy polymer and E-glass hybrid composite were characterized. Woven bamboo laminates were woven from bamboo strips, and the hybrid composites were obtained by manually stacking alternating 2-6 laminates of woven bamboo, E-glass and epoxy. The findings show that increasing the woven bamboo layers from 2 to 6 did not improve the tensile strength, modulus, impact and flexural strength. However, the hardness strength was increased. Overall, the minimum or maximum number of laminated bamboo fiber/E-glass/epoxy hybrid composite layers can be used in various product applications. The work is then extended to developed anti-ballistic materials that satisfy National Institute of Justice (NIJ) standard to be registered as be registered as combat armor panel or materials. The results show that the composites withstand 482.5 m/s ± 5 limit of bullet velocity and satisfied the NIJ of level II. The findings give strong base to consider bamboo composite to replace synthetic composites in green engineering applications.

Abstract
A reactive hydride composite (RHC) for solid-state hydrogen storage materials

Hydrogen storage using the metal hydrides and complex hydrides is the most convenient method because it is safe, enables high hydrogen capacity and requires optimum operating condition. Metal hydrides and complex hydrides offer high gravimetric capacity that allows storage of large amounts of hydrogen. However, the high operating temperature and low reversibility hindered the practical implementation of the metal hydrides and complex hydrides. An approach of combining two or more hydrides, which is called reactive hydride composite (RHC), was introduced to improve the performance of the metal hydrides and complex hydrides. The RHC system approach has significantly enhanced the hydrogen storage performance of the metal hydrides and complex hydrides by modifying the thermodynamics of the composite system through the metathesis reaction that occurred between the hydrides, hence enhancing the kinetic and reversibility performance of the composite system. Thermodynamic destabilization is achieved when mixing two or more metal hydride/complex hydride that form a new compound during dehydrogenation process. In this talk, an application of X-ray diffraction (XRD) analysis in the RHC system to detect a new compound that form during dehydrogenation process is discussed. The XRD analysis is a simple technique to detect a new compound in the RHC system. The challenges and perspectives of the RHC system are also discussed.

Cobalt Oxide nanostructured for electrochemical and photocatalytic applications

In recent years, nano metal oxides are widely known for their potential applications in science and technology. This has led to progress in several processes for the preparation of nanoparticles, including anticipated physiognomies, corresponding dimensions, forms, morphology, imperfections in the crystal construction, and monodispersion, for potential use in medicament applications. The nanostructured materials received much attention due to their distinctive properties such as higher damping, mechanical stability, high strength, and good thermal conductivity. The nanostructured metal oxides, in general, maintains the high surface area and that developed much interest in the research due to its wide range of applications including optical electronics, sensing devices, and nanoelectronics. Photocatalysis technology offers excellent potentials for the complete removal of organic and other biochemical pollutants in an environmentally friendly and sustainable means where the outcome is without the involvement of greenhouse gas emissions. It has been found that under UV-Visible light irradiation, the nanostructured semiconductor metal oxide photocatalysts can easily degrade many different organic and biochemical pollutants. Since the photocatalysis is a process which involves the breaks down or decomposition of various dyes, organic dirt, and biological species like harmful fungi and viruses by making use of the UV or visible light in a sustainable manner. Herein we report on various surface morphological characteristics of the synthesized cobalt oxide (Co3O4) nanostructures obtained by means of facile one-step hydrothermal method for oxygen reduction reaction (ORR). The synthesized nanostructures of Co3O4 were adequately characterized by field emission scanning electron microscopy (FESEM) fitted with Energy-dispersive X-ray spectroscopy (EDX) elemental mapping, X-ray diffraction (XRD) and Raman techniques. The electrochemical studies were carried out to analyse the performance of as-synthesized catalysts for ORR by cyclic voltammetry (CV), and chronoamperometric (CA) techniques Further testing of the photocatalytic activity through the degradation of various dye confirmed for an effective and potential catalytic nature of the synthesized samples.
