Abstract: The present disclosure discloses a waterborne inorganic anti-doodling ceramic paint for indoor walls and preparation method thereof; the ceramic paint is a dual-coating paint having an under-coating paint and a surface-coating paint. The advantage effects of the present disclosure is that: the main film-forming materials are inorganic materials, the solvent is mostly deionized water, VOC emission is extremely low, thereby having a characteristics of safety, health and environmental protection; overcoming the shortcomings of multi-components of ceramic paint needs to be aged before use, while the under-coating paint and the surface-coating paint of the present disclosure are all single-component and can be directly used, easily to apply and fast; having an anti-doodling effect, when a marker doodling on the walls, it can be easily erased; the coating has a low surface tension which can isolate the outdoor moisture and prevent the walls from getting wet and mildewed.

Abstract: A peptide, including: a first peptide fragment including (KG)n or (GK)n where n is an integer between 2 and 5, K represents a lysine residue, and G represents a glycine residue; a second peptide fragment including an identification sequence; and a first connection peptide including 1-2 glycine residues. The first connection peptide is disposed between the first peptide fragment and the second peptide fragment.

Abstract: An electrical connector having an insulative housing having a mating cavity and a plurality of passageways, a plurality of electrical contacts received in the corresponding passageways and a sealing member received in the mating cavity. The insulative housing defines a front face and a mounting wall, the mating cavity is formed between the front face and the mounting wall. Each electrical contact has a contacting portion, a tail portion, and a main portion connecting the contacting portion with the tail portion, each main portion defines a plurality of barbs on both sides thereof. The sealing member has a base portion and at least one opening defined in the base portion for tail portions passing through. At least one electrical contact defines a wing on one side thereof, and the sealing member is restricted between the wing and the mounting wall.
