Abstract: The present invention features interferon-free therapies for the treatment of HCV. Preferably, the treatment is over a shorter duration of treatment, such as no more than 12 weeks. In one aspect, the treatment comprises administering at least two direct acting antiviral agents to a subject with HCV infection, wherein the treatment lasts for 12 weeks and does not include administration of either interferon or ribavirin, and said at least two direct acting antiviral agents comprise (a) Compound 1 or a pharmaceutically acceptable salt thereof and (b) Compound 2 or a pharmaceutically acceptable salt thereof.

Abstract: Provided are an electrochemical gas sensor and a fabrication method therefor. A sensing electrode, a reference electrode and an auxiliary electrode in a planar arrangement are arranged on an upper layer in a sensor housing, and an electrolyte and a membrane material are arranged on a lower layer in the sensor housing. An upper part of the sensor housing is provided with a vent, and a lower part of the sensor housing is provided with a connector for connecting three electrodes and connected to an external circuit. Compared with the traditional cylindrical stacked electrochemical gas sensor, the fabrication method for a plate-body thin-film type sensor is simple, is less affected by the change of ambient pressure, temperature and humidity, and is beneficial to the flattening and miniaturization of electronic instruments and apparatus for gas analysis.

Abstract: The present disclosure provides core-shell nickel ferrite, a nickel ferrite@C material and preparation methods and application thereof. The preparation method of the core-shell nickel ferrite includes: preparing nickel iron glycerate ball powder by a solvothermal method; and under an air condition, heating the nickel iron glycerate ball powder at a heating rate of lower than 1.5° C./min to not less than 350° C. for performing calcination to obtain the core-shell nickel ferrite. The preparation method of the nickel ferrite@C material includes: performing a phenolic resin condensation reaction on the core-shell nickel ferrite, resorcinol and formaldehyde to obtain a phenolic resin (RF) coated core-shell nickel ferrite@RF composite material; and in an inert atmosphere, calcining and carbonizing the nickel ferrite@RF composite material to obtain the nickel ferrite@C material.
