The invention relates to a method for carrying out surface modification on a quantum dot / rod, preparation of a photosynthetic catalyst as well as a system and a method. The surface modification is carried out on the quantum dot / rod, and the quantum dot / rod is simply and rapidly used as a carrier; and metal ions which are used as catalytic activity sites are further key-bonded and assembled on the surface of the quantum dot to prepare a high-activity photosynthetic hydrogen-producing photocatalyst and prepare hydrogen. According to the method for carrying out the surface modification on the quantum dot / rod, the preparation of the photosynthetic catalyst as well as the system and the method disclosed by the invention, high-efficiency photosynthetic hydrogen production can be realized by the simple, low-cost and stable photocatalyst; complicated and unstable catalytic activity centers which is natural or artificially-simulated and the like do not need so as to avoid complicated synthesis and system construction; and the method disclosed by the invention has the advantages of efficient reaction, simplicity in reaction, low cost and practical applicability, and provides an effective way for effectively reducing the photosynthetic hydrogen production cost and improving the catalytic efficiency.

Specific target polypeptide self-assembled nano-carrier, drug-carrying nanoparticle and preparation method

The invention relates to the technical field of biology and in particular relates to a specific target polypeptide self-assembled nanoparticle. The nanoparticle is prepared from a hydrophobic anti-tumor drug with a therapeutic dosage and an amphipathic polypeptide which covers the periphery of the hydrophobic anti-tumor drug through a self-assembling manner, wherein the amphipathic polypeptide is a target peptide which can be used for specifically targeting a epidermal growth factor receptor of a tumor cell; a terminal N of the target peptide is coupled with a hydrophobic functional molecule. After the nanoparticle targets the tumor cell, the target peptide is exposed; the nanoparticle targets the tumor cell and enters the tumor cell through receptor-mediated endocytosis, and the drug is released to inhibit DNA (Deoxyribonucleic Acid) synthesis and repairing; the nanoparticle has dual killing effects on the tumor cells and the growth of the tumor cell is inhibited. The amphipathic polypeptide does not generate a covalent bond in a self-assembling process and no reverse reaction is caused; the specific target polypeptide self-assembled nanoparticle is used for treating tumors and has the advantages of no toxin and good biocompatibility.

Household garbage classified gasification system with rotary kiln gasification and plasma fusion capability

The invention discloses a household garbage classified gasification system with rotary kiln gasification and plasma fusion capability. The household garbage classified gasification system comprises a rubbish feeder, a rotary kiln type pyrolysis vaporizer, a metal sorting machine, a crusher, a high-temperature cyclone separator, an ash hopper, an ash feeder, a plasma fusion furnace and an air preheater; household garbage is sequentially subjected to the pyrolysis gasification, metal sorting and crushing of the rotary kiln type pyrolysis vaporizer and the further gasification treatment of the plasma fusion furnace; the low-temperature rotary kiln vaporizer and the high-temperature plasma fusion furnace can be effectively combined, and the ash generated by pyrolysis and gasification of the rotary kiln vaporizer is fused by virtue of taking plasma torch as a high-quality heat source; the household garbage classified gasification system can effectively take the heat of synthesis gas and the gas fume generated by the fusion furnace as an outer heat source of the rotary kiln vaporizer so as to heat the air entering in the plasma fusion furnace, the comprehensive energy use efficiency is improved, and the secondary pollution problem of dioxin and heavy metal is avoided.
