Abstract: The BC powders (particle size<10 ?m, Taiwan Paiho) are activated with surfactant sodium alginate under stirred for 1 h. The as-prepared BC powders (2 g) are immersed into 100 mL of biamminesilver nitrate ([Ag(NH3)2]NO3) solutions, which are formed by adding 28 wt. % aqueous ammonia into AgNO3 solution at room temperature. After stirring for 1 h, dilute aqueous solutions of hydrazine monohydrate are separately prepared and introduced to the BC-AgNO3 solutions in appropriate quantities (molar ratio 1:1 with respect to silver nitrate) by a syringe. Stirring is continued under inert atmosphere at room temperature for another 4 h. The BC/Ag particles are separated and washed with deionized water and ethanol, then dried in vacuum at 60° C. for overnight.

Abstract: The present invention provides a manufactured aggregate material that converts waste materials and/or recyclable materials into construction material. By mixing waste materials with an acid solution and a metal oxide solution, any harmful contaminates in the waste materials are encapsulated and rendered into hard pellets that are suitable for use in conglomerates or composites such as concrete. The manufactured aggregate material may be adjusted for moisture content, density, heat capacity, and other parameters.

Abstract: This invention relates to the use of a filler derived from cereal husk, more particularly rice husk, in composite materials to enhance the flame retardant, antistatic, accelerator, plasticiser and blowing characteristics in various composite materials.

Abstract: Disclosed are amorphous precipitated silicas, silica gels, and amorphous carbons derived from biomass and methods of producing them with and without adhered or deposited amorphous carbons produced by acidifying a caustic silicate solution produced by caustic digestion of biomass ash containing silica with and without activated carbon, the ash being obtained from thermal pyrolysis of the biomass, the acidifying effective to produce a slurry of the precipitated silica and silica gels with and without adhered or deposited amorphous carbon, and separated from the slurry the precipitated silicas and silica gels with and without the adhered or deposited amorphous carbons. The properties of the precipitated silica with adhered or deposited carbon being within the range as utilized in rubber compositions thereby avoiding the blending of silica and carbon components for such use.
