The material includes an inner polyurethane layer, an outer polyurethane layer, and a textile reinforcing layer. The textile reinforcing layer is arranged between the inner polyurethane layer and the outer polyurethane layer. The inner polyurethane layer and the outer polyurethane layer comprise thermoset polyurethane. The textile reinforcing layer comprises apertures through which the inner polyurethane layer and the outer polyurethane layer are connected to each other.

Reproduction of a stem cell niche of an organism and method for the generation thereof

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.

System for creating a structure including a vasculature network

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.

A method for forming a composite article includes adding an upper skin at least partially over a failsafe torque tube. The failsafe torque tube includes an inner tube and an outer tube. The method also includes adding a lower skin at least partially under the failsafe torque tube. The upper skin, the lower skin, and the outer tube are made of a composite material. The method also includes co-curing the upper skin, the lower skin, and the outer tube together to produce the composite article.

Electric field “Z” direction alignment of nanoparticles in polymer solutions

A method of preparing a polymer film having an oriented dispersed material includes casting a multi-layer polymer solution having a first polymer solution layer and a second polymer solution layer where the second polymer solution layer is at least partially immiscible with the first polymer solution layer. The method further includes passing the multi-layer polymer solution through an electric field application zone, to thereby induce orientation of the dispersed material. A multi-layer polymer film can then be formed by drying the solvent from the multi-layer polymer solution. An apparatus for preparing polymer films includes a top electrode made from a flexible metal mesh coated with a non-stick, non-conductive coating.

Folded side-leakage-proof arc-shaped elastic sanitary product wainscot and production line therefor
10702425 · 2020-07-07 ·

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.
