Using method of mexolamine in manioc and sisal hemp field

Abstract: The invention relates to the purpose of herbicide and the usage thereof, in particular to the selectivity of the sulfonylurea family herbicide sulfometuron-methy to the economic crop cassava and sisaland the usage in the filed of the two crops. The invention is characterized in that the sulfometuron-methy is used as the selective herbicide to remove various ruderal in the cassava and the sisal fields. The sulfometuron-methy has high safety on the cassava and the sisal, has efficient weeding effect, and is economical herbicide.

Preparation method of MoSe2-MoO2 sisal fiber activated carbon lithium ion battery anode material

Abstract: The invention discloses a preparation method of a MoSe2-MoO2 sisal fiber activated carbon lithium ion battery anode material, and belongs to the technical field of lithium ion batteries. The preparation method comprises the following steps: (1) cleaning sisal fibers, cutting the cleaned sisal fibers into small sections, carrying out earlier-stage treatment on the sisal fibers, namely soaking the sisal fibers into a sodium hydroxide solution containing isopropanol to carry out hydrothermal reaction, and carrying out high-temperature calcination to obtain sisal fiber activated carbon; 2) weighing a molybdenum source and a selenium source, adding the molybdenum source and the selenium source into deionized water, dissolving and transferring into a reaction kettle; then adding the sisal fiberactivated carbon powder, adding polyethylene glycol and hydrazine hydrate, performing uniform stirring, then putting the mixture into a blast drying oven for hydrothermal reaction, and filtering, cleaning and drying a sample obtained after the reaction is finished, so as to obtain the MoSe2-MoO2 sisal fiber activated carbon lithium ion battery anode material. The lithium ion battery anode materialprepared by the invention has the excellent electrochemical performance, relatively high specific capacity and good cycling stability.

Enhancement of mechanical, thermal and antibacterial properties of sisal/PHBV biocomposite by fibre modification

Abstract: Lignocellulosic biocomposite is a promising biodegradable materials, though improvement of the interfacial adhesion between cellulose fibre and polymer matrix is still challenged. Therefore, this work investigated the effect of propionylation of sisal reinforced fibre in the sisal/polyhydroxybutyrate-co-valerate (PHBV) biocomposite. Propionylation involved esterification substitution of propionic anhydride to hydroxyl group of sisal fibre, where ester group (COOR) of propionylated fibre was successfully observed by Fourier transform Infrared spectroscopy (FTIR). Then mechanical and thermal properties were evaluated and biodegradation characteristics were assessed. The tensile strength and modulus of propionylated sisal/PHBV biocomposite were greater than unmodified sisal/PHBV, which revealed better compatibility at the interface. In addition, propionate moieties of sisal fibre could induce crystalline formation of PHBV, as determined by an increase of crystalline phase. The higher decomposition temperature (Td) and activation energy (Ea) of 155 kJ·mol -1 , determined by thermal gravimetric analyser (TGA), were strong confirmation of good thermal resistance of the propionylated sisal biocomposite. The storage modulus, as characterized by dynamic mechanical thermal analyser (DMTA), also revealed the improvement of stiffness. Bacterial growth tests evaluated the inhibition of bacterial growth on the PHBV biocomposites. It was clear that propionylation of sisal fibre decreased colonization of Staphylococcus aureus (SA) and Escherichia coli ( E.coli ).
