Abstract: The present invention relates to a bioink for 3D printing, the preparation method, and the usage. Such bioink is a gel made of ?-zein, porogen by 0-10% of the weight of zein, ethanol and water. The preparation method consists of: 10-50% zein is dissolved into an aqueous solution containing 40-90% (v/v) of ethanol, then, the porogen by 0-10% of the weight of zein is added, and then, this solution is allowed to stand at 5-95° C. for 1-10 days, or stirred for 30 min-24 hours, and thus, the bioink for 3D printing can be obtained. The conditions applied to prepare such bioink are mild and the method adopted is easy to operate, in addition, the said bioink for 3D printing has good mechanical properties and biocompatibility, which can be applied in the field of biomedicine for preparing tissue engineered substitutes and hemostatic materials by 3D printing at room temperature.

Abstract: The present application provides a process for preparing an epitaxy wafer, and an epitaxy wafer prepared therefrom. The process comprises: step S1: providing a semiconductor substrate wafer, conducting an epitaxy process and forming an epitaxy layer on the wafer; and step S2: conducting a thermal treatment to the wafer to eliminate the haze pattern of the epitaxy layer. According to the process, the thermal treatment after the epitaxy process can facilitate the orientation of atoms on the wafer surface toward the lowest energy orientation, so that the atoms of the epitaxy layer arrange and accumulate uniformly. Therefore, the haze pattern on the wafer surface can be eliminated.

Abstract: This application provides an epitaxial wafer processing method, the processing method comprises providing an epitaxial wafer; measuring the flatness of the epitaxial wafer; performing vapor phase etching for the epitaxial wafer not meet the standard; growing epitaxial layer on the epitaxial wafer after the vapor phase etching. Compared with the traditional polishing rework process, the vapor phase etching for the epitaxial wafer of this application is much simpler and faster, therefore it can improve the production yield.

Abstract: Automatically stretchable folding spectacles, comprising: a first rim, with a first lens being provided within the first rim; a second rim, with a second lens being provided within the second rim; a first leg; and a second leg, wherein the first rim and the first leg are elastically connected via a first elastic member; the second rim and second leg are elastically connected via a second elastic member; a middle beam mechanism is provided between the first rim and second rim; and a locking mechanism is provided between the first leg and the second leg, which makes the spectacles capable of keeping a folded state after the spectacles are completely folded. The wearer needs only to press the locking mechanism with one hand, and the whole spectacles will stretch naturally and exhibit an available state under the action of the tension of the elastic members.

Abstract: A hair styler is used for conditioning, drying, and curling hair, comprising a cylindrical hair styler body with a hair curling lever on the hair styler. A handle is coaxially provided on one end of the hair styler body. A micro motor is provided in the handle. The said micro motor drives the hair styler body to relatively rotate about the handle alongside its axis. The handle is disposed of control switch controlling rotation of control motor; the heat generated by energization of the hair styler body or that is set up in the hair styler body directly heats up the electric heater adjacent to the hair styler body. The invention features advantages such as easy operation as well as functions of hair curling, drying, conditioning, and scalp care.
