Abstract: The present disclosure provides a grating including: a first substrate including stacked first and second electrode layers each including strip-shaped electrodes with an identical width, strip-shaped electrodes in the first and second electrode layers arranged alternately; a second substrate opposite to the first substrate with a liquid crystal layer therebetween; driving modules for driving the strip-shaped electrodes to form light shading parts and light transmission parts, one light shading part and one adjacent light transmission part defining a grating unit, at least one grating unit defining a grating part, the driving modules arranged in one-to-one correspondence with the grating parts; and a control module for generating driving signals in one-to-one correspondence with the driving modules according to a distance between the human eyes and the grating, thereby changing a width of the grating unit corresponding to a crosstalk position. A 3D display device and a grating driving method are provided.

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 relates to protein-conjugated quantum dot compositions. The compositions may comprise, for example, zein proteins, and may be configured as films, for example on the sample-contacting surface of a sample well. Methods, kits, and an apparatus for the detection of food-borne microorganisms, for example, are also disclosed.
