Abstract: A delignified wood material is formed by removing substantially all of the lignin from natural wood. The resulting delignified wood retains cellulose-based lumina of the natural wood, with nanofibers of the cellulose microfibrils being substantially aligned along a common direction. The unique microstructure and composition of the delignified wood can provide advantageous thermal insulation and mechanical properties, among other advantages described herein. The thermal and mechanical properties of the delignified wood material can be tailored by pressing or densifying the delignified wood, with increased densification yielding improved strength and thermal conductivity. The chemical composition of the delignified wood also offers unique optical properties that enable passive cooling under solar illumination.

Abstract: Provided are a pharmaceutical composition of an aquaporin inhibitor and a preparation method thereof. The pharmaceutical composition comprises 2-((3,5-bis (trifluoromethyl) phenyl)carbamoyl)-4-chlorophenyl dihydrogen phosphate or a pharmaceutically acceptable salt thereof, or a pharmaceutically acceptable solvate thereof, and meglumine. The pharmaceutical composition of the aquaporin inhibitor and the preparation method thereof have the following advantages: the process is simple, has strong operability, and is conducive to industrial production, and the product has good stability, and obviously less content of degradable impurities, which ensures the effectiveness of the medicine.

Abstract: Disclosed is a hat which can be made of multiple pieces or one integral piece of soft material sewed into a hat body having a crown portion and a brim portion. An elastic band is sewed onto and along a lower inner periphery of the crown portion of the hat body in specially patterned stitches to replace the lining band and decorative hat band usually used on a conventional hat. The hat can be folded without becoming deformed. The elastic band provides the hat with adjustable size and tightness to suit to different head shapes and sizes.

Abstract: A waste purifying device employing an intermediate exhaust fan and a vacuum pump to suck the waste gas flowing from a waste gas source toward a chimney into at least one washing tank through a pipe line, the washing tank containing a washing liquid which can remove the particles or toxic gas in the waste gas, the purified gas being then discharged from the chimney.
