    Abstract

    Biochar produced during the thermochemical decomposition of biomass not only reduces the amount of carbon emitted into the atmosphere, but it is also an environment-friendly replacement for activated carbon and other carbon materials. In this review paper, researches on biochar are discussed in terms of production method and application. Different processes for biochar production, such as pyrolysis, gasification, hydrothermal carbonization, etc., are compared. Physical and chemical activation methods used to improve the physicochemical properties of biochar and their effects are also compared. Various environmental application fields of biochar including adsorption (for water pollutants and for air pollutants), catalysis (for syngas upgrading, for biodiesel production, and for air pollutant treatment), and soil conditioning are discussed. Recent research trend of biochar in other applications, such as fuel cell, supercapacitor, and hydrogen storage, is also reviewed.

    Abstract

    Natural hydrophilic polymers have been utilized for a variety of applications, ranging from the food industry to the coatings industry. However, recent social needs have demanded rapid progress with regard to medical and environmental applications. Natural hydrophilic polymers have attracted considerable interest due to their physicochemical properties and useful functions. This report explores recent findings made in medical, environmental, and food applications of natural hydrophilic polymers and their modified polymers. Applications of these materials are based on their intrinsic biocompatibility, biodegradability, and non-toxicity. Advances in the chemical modification of natural polymers as well as new source developments are overcoming the physicochemical property limits and high costs of these materials, opening up new opportunities for the development of future applications.

    Abstract

    Laminated boards were produced by laminating banana stem fibre boards with banana leaf tapes. Various laminated boards were created by changing the number of layers of leaf tapes used. The tensile strength, elongation at break, flexural modulus and impact strength of the laminated boards increased with increasing number of layers of the leaf tapes. The elastic modulus of the laminated boards, however, showed the opposite trend. The orientation of fibre in the leaf tapes has little effect on impact strength but other properties studied showed that the properties measured along the fibre orientation were higher than that in the perpendicular direction.
