The present invention relates firstly to a method for reproducing a stem cell niche of an organism. The invention further relates to a reproduction of a stem cell niche of an organism. According to the invention, an image of a tissue of an organism is generated, which tissue comprises at least one stem cell niche. The image is filtered in order to obtain a structural pattern of the imaged stem cell niche. In a further step, a lithographic mask is generated from the structural pattern. According to the invention, a starting material of a substrate is structured by means of indirect or direct application of the lithographic mask, whereby a structured substrate is obtained which represents the reproduction of the imaged stem cell niche of the organism. The reproduction can be characterised as biolithomorphic.

Provided is a daylighting film (10) including: a base (11) having light-transmissive performance; a plurality of first protrusion portions (12) that have light-transmissive performance and are provided to be adjacent to each other on one surface (11a) of the base (11); a gap portion (13) provided between the first protrusion portions (12); and at least one second protrusion portion (14) that is provided in at least one gap portion (13) to be adjacent to the first protrusion portions (12) on the one surface (11a) of the base (11) and that is formed of the same material as that of the first protrusion portions (12), in which a height of the second protrusion portion (14) from the one surface (11a) of the base (11) is smaller than a height of each of the first protrusion portions (12) from the one surface (11a) of the base (11).

A system and method is provided for creating a structure including a vasculature network. A film deposition device is configured to dispense droplets onto a surface of a substrate to form a curable fugitive pre-patterned liquid film on the surface of the substrate. An electrohydrodynamic film patterning (EHD-FP) device has a patterned electrode structure formed to generate an electric field and to subject the film on the surface of the substrate to the electric field. The film thereby being formed by the EHD-FP into patterned features in response to being subjected to the electric field. Then a casting system is configured to cover the patterned features in an epoxy to form patterned structures, wherein the patterned structures comprise a fugitive vasculature structure.

The present invention relates to a folded side-leakage-proof arc-shaped elastic sanitary product wainscot and a production line therefor. After two sides of an elastic membrane under a tensile state are compounded with nonwoven fabric strips by hot pressing respectively, the elastic membrane rebounds and resets to impel the nonwoven fabric strips located on two sides of the elastic membrane to form a folded side-leakage-proof side wall. The elastic membrane is in the shape of a concave arc. The present invention has the following advantages: 1, the nonwoven fabric strips may be compounded with two sides of the elastic air-permeable membrane without a hot melt adhesive so as to ensure that the air permeability of the elastic air-permeable membrane and the nonwoven fabric strips is not affected by the hot melt adhesive; and 2, after two sides of the elastic air-permeable membrane under a tensile state are compounded with the nonwoven fabric strips, the elastic air-permeable membrane rebounds to impel the nonwoven fabric strips to form a required elastic folded side-leakage-proof side wall with the rebound and reset of the elastic air-permeable membrane. This side wall not only has a function of preventing liquid from flowing, but also greatly reduces a contact area between a sanitary napkin or a panty-shape diaper and a human body, such that the comfort level of the human body is greatly improved.

In this molded surface fastener, plural engaging elements having a stem portion and an engaging head portion formed integrally on the stem portion are standing on the base portion, at least one pawl portion having a pawl width dimension narrower than a width dimension at a boundary between the stem portion and the engaging head portion is protruded on an outer peripheral edge part of the engaging head portion, and a back surface of pawl of the pawl portion is formed at different angles with respect to a back surface of head portion of the engaging head portion. Such a molded surface fastener of the present invention has a substantial engaging force with respect to a female surface fastener and can make a texture of its surface comfortable.

In this molded surface fastener, an engaging element includes a columnar stem portion, and micro pawl portions protruding outward from an upper end outer peripheral edge of the stem portion in a plan view of the engaging elements.
