摘要： Copper ion-doped carbon dots (Cu-CDs) and a preparation method thereof are disclosed. The preparation method includes the following steps: using copper nitrate as a dopant to generate a complex of polyacrylic acid and copper ions as a precursor by an in situ polymerization; standing overnight, and performing repeated suction filtration to collect filter residues; then, performing pyrolysis and carbonization to generate carbonized products, dispersing in ultrapure water, taking a supernatant, and then performing extraction and purification to obtain the CDs. When the Cu-CDs prepared by the present invention are used in photodynamic therapy, photothermal/photodynamic synergistic therapy is not required, and the Cu-CDs are suitable for the therapeutic process of skin cancer, lung cancer, pancreatic cancer, esophageal cancer, brain glioma, as well as some skin diseases and ophthalmological diseases.

摘要： A method of making a multi-composition fiber is provided, which includes providing a precursor laden environment, and forming a fiber in the precursor laden environment using laser heating. The precursor laden environment includes a primary precursor material and an elemental precursor material. The formed fiber includes a primary fiber material and an elemental additive material, where the elemental additive material has too large an atom size to fit within a single crystalline domain within a crystalline structure of the fiber, and is deposited on grain boundaries between adjacent crystalline domains of the primary fiber material to present an energy barrier to atomic diffusion through the grain boundaries, and to increase creep resistance by slowing down growth between the adjacent crystalline domains of the primary fiber material.

摘要： An iron-carbon composite material and a preparation method thereof are disclosed. The iron-carbon composite material includes a three-layer core-shell structure, which successively includes a porous graphite carbon outer layer, an iron carbide intermediate layer and a nano zero-valent iron core from outside to inside. The present invention wraps nano zero-valent iron in porous graphite carbon and iron carbide, which can prevent the oxidation of nano zero-valent iron, while iron carbide effectively improves the ability to fix arsenic, realizing high efficiency and long-term use of nano zero-valent iron. Iron carbide may effectively adsorb and fix arsenic, and especially efficiently oxidize As(III) to relatively low-toxic As(V).
