The present paper reviews the development of zinc-air battery. Due to its high energy density advantage, the electrochemical system has been extensively studied and developed. However, major problems associated with the electrochemical system remain a formidable challenge, the utmost being to develop an electrically rechargeable zinc-air battery. E

Carbon nanomaterials (CNMs) are promising in many potential applications for their attractive physical and chemical properties. Chemical vapor deposition technique (CVD) is used to synthesize CNMs on fixed substrate. Powdered activated carbon (PAC) was used as a successful substrate for CNMs growth in CVD reaction process. Iron clustered nano parti

Introduction: The objective of this study was to investigate the effects of lead on concentration and motility of spermatozoa recovered from epididymis and testes in mature male offspring whose mothers were exposed to different doses and concentrations of lead acetate during gestation period. Materials and Methods: Seventy two healthy mature female

This paper evaluates the authors’ experiences in supervising a construction of a landscape project of an institution. The works involved an upgrading of the landscape and hardscape of the main entrance, while the supervision was originally devised by several lecturers. The live project provided good impacts to both students and lecturers. For ins

The rapid changes in business operations and the frequency at which new products and services are introduced to market by competing organizations continue to emphasize the importance of effective management of knowledge that resides in every organization. Knowledge Management Systems (KMS) which are tools enabling the management of organizational k

Malaysia is home for numerous venomous animals which are either terrestrial or marine. However, many of these venoms are not well studied and the active components of the toxins and venoms are remain biochemically and pharmacologically unknown. In recent years, advancement of proteomics technology has enabled rapid and massive discoveries in the co

cadmium loaded carbon nanotubes (CNTs) for re-adsorption of the same metal cadmium (Cd). The desorption of cadmium ions (Cd2+) by batch mode laboratory experiments was investigated for hydrochloric and nitric acids, where the former gave better desorption compared to the other acid. Initial experiments revealed that hydrochloric acid (HCl) was bett

Quantification of the pollutants generated due to rainfall-runoff process is tedious and expensive. On the other hand, the characteristics of runoff quality also depend on the landuses and rainfall patterns. Such difficulties can be simplified by the development of reliable and easy to use nonpoint source (NPS) regression models. Information on the
