Abstract: The present application discloses a catalyst for thermally stably degradation of VOCs, a preparation method thereof and a use thereof. The catalyst includes: a substrate, and an auxiliary agent and an active component which are on the substrate. The auxiliary agent includes a first auxiliary agent and a second auxiliary agent; the first auxiliary agent includes a cobalt-containing auxiliary agent and/or an iron-containing auxiliary agent; and the second auxiliary agent includes an aluminum-based auxiliary agent. The combination of specific first and second auxiliary agents is introduced into the catalyst of the present application, so that oxygen molecules can be quickly adsorbed and activated during the catalytic combustion process of VOCs with forming a catalytic synergy center with the active component, thereby improving the removal efficiency for VOCs and facilitating the long-term stable operation of the catalyst under harsh conditions such as high-temperature and high-humidity conditions.

Abstract: A CD44 antibody is used in preparation of a medicine for treating Parkinson's disease (PD). By means of a stereotactic injection method, the CD44 antibody (anti-CD44) is injected into the cortex part of PD model mice, and it is found that the antibody can significantly alleviate PD-related symptoms, such as improve the motor functions of the mice, restore the number of dopaminergic neurons in the substantia nigra part and inhibit neuroinflammation.

Abstract: The present application discloses a monolithic catalyst with the function of selective adsorption-catalytic oxidation of organic waste gas and a preparation method and application thereof. The present application adopts a double coating design. A first coating is a molecular sieve primer coating. A second coating is an active component coating, which uses a neutral silica sol, so as to protect the activity and effectiveness of a noble metal and a catalytic promoter on the molecular sieve.

Abstract: The invention discloses a fastener made from a carbon/carbon composite and a manufacturing technique thereof. The fastener can be adopted in a high-temperature furnace or corrosive environment to replace a graphite fastener or a molybdenum fastener, and is made from carbon fiber via the steps of felt making, densifying, plastifying modification, machining and purifying.
