    • PURPOSE: An organic-inorganic composite high-strength cementless concrete composition is provided to maintain a superior range of compressive strength without cement by inducing geopolymerization. CONSTITUTION: A cementless concrete composition includes an inorganic binder, aggregate, room-temperature hardening hydrophilic polymer, a self-emulsifying hardening agent, and an activator. The inorganic binder includes fly ash and blast slag. The activator includes alkaline metal hydroxide and alkaline silicate. The fineness of the fly ash is between 2000 and 6000 cm^2/g. The fineness of the blast slag is between 2000 and 4000cm^2/g. The weight ratio of the fly ash and the blast slag is between 80:20 and 20:80. The weight ratio of the alkaline metal hydroxide and the alkaline silicate is between 1:2 and 2:1.

    • PURPOSE: A manufacturing method of tellurium-based nano-wires and bismuth telluride nano-tubes is provided to obtain the tellurium-based nano-wires by mixing a coupling agent and tellurium oxides with organic solvents of high boiling points. CONSTITUTION: A manufacturing method of tellurium-based nano-wires includes the following: one or more organic solvents are mixed with a coupling agent to become a mixed solution; and a tellurium oxide selected from a group including TeO_2, TeO, TeO_3, Te_2O_5, and Te_4O_9 to be reacted. The organic solvents are selected from a group including ethylene glycol, oleic acid, oleylamine, hexadecane, ethylene diamine, dimethyl formamide, pyridine, and acetone. The coupling agent is made of trialkyl phosphine, trialkyl phosphine oxide, alkyl amine, alkyl thiol, phenyl sulfone, or aminophenyl sulfone. The pH value of the mixed solution is adjusted in a range between 8 and 13.
