Abstract: A blue light blocking film layer and a blue light blocking system are disclosed.

Abstract: The present invention provides an artificial skin and a preparation method thereof. The present invention takes the xenogeneic acellular dermal matrix particles as main materials, and obtains the dermis layer by three-dimensional printing technologies, and then obtains the artificial skin by combining the epidermis layer with the dermis layer. The dermis layer of artificial skin in present invention has three-dimensional porous structure, which retains main components of natural dermal matrix in composition, and imitates distributed structure at fiber bundle diameter and pore size of natural dermal matrix in structure. This kind of novel biomimetic dermal scaffolds have obvious advantages in inducing migration and regeneration of skin cells, accelerating vascularization, promoting wound healing and improving healing quality.

Abstract: Disclosed is a blue light absorbing compound, its preparation method and use. The compound has high stability and is suitable for high temperature processing conditions as well as outdoor application. A method of covalently bonding a blue light absorbing compound with an ultraviolet light absorbing compound for increasing its stability is also provided. The compound is capable of absorbing or blocking ultraviolet light (UVA, UVB) and blue light to protect eyes. But long-wavelength blue light can be absorbed diminishingly, so that the transmitted light has a particularly good visual experience.

Abstract: The present invention discloses a 3-aryl-benzofuranone compound in which R1-R6 in the formula are mutually independent H or C1-C20 alkyls, and R7 is C7-C20 alkyl or C7-C20 mixed alkyl. The present invention also discloses a composition of 3-aryl-benzofuranone compound and the preparation method. The 3-aryl-benzofuranone compound and the composition thereof has the superiority in application due to the characteristics of less proneness to volatilize, less proneness to be extracted, higher resistance to migration and less proneness to bloom and precipitate on the surface of organic materials, and with a wide range of application, it is effective during the application.

Abstract: A blue light blocking system including a pyrazoline compound of formula (I) or/and a phenylacrylic compound of formula (II) is provided. The compound of formula (I) or formula (II) can absorb most blue light of shorter wavelength that hurt eyes, but let that of the longer wavelength pass through, so that the transmitted light makes an excellent visual effect for human. The system can be applied to products such as optical films, optical lenses, goggles, skin care, lighting, coatings, adhesives, or panels. These products have a light-colored appearance and their transmitted light makes for an excellent visual effect.

Abstract: The present invention relates to a system for tapping and collecting rubber. The system includes a tapping apparatus for tapping rubber and a collecting apparatus for collecting tapped rubber. The tapping apparatus includes a rail directing a drill bit or blade to move between one end of the rail to another end of the rail and to remove tree bark during the movement and a mounting structure configured to hold the rail and connect the tapping apparatus to a tree or plant. The collecting apparatus is positioned below the tapping apparatus for collecting rubber that exudes from a cut tree or plant. The collecting apparatus includes a slide and a tube having an opening and a divider that separates the tube into multiple sections.
