The present invention relates to a porous scaffold having excellent tissue engineering properties, and a method for manufacturing same. The scaffold of the present invention can be manufactured by a simple process, and exhibits high tensile strength and biocompatibility, as well as an excellent cell engraftment rate, and thus can be useful as a support composition for various of human transplantation, for example, as a support for artificial ligaments or abdominal wall reinforcement.

A robot end effector for surface preparation in an automated inspection and repair system for composite parts has an end effector body and a plasma control unit and a plasma jet nozzle supported on the end effector body. The plasma control unit directs a jet of atmospheric plasma through the plasma jet nozzle. A slave tool changer is secured to the end effector body. The slave tool changer releasably and operatively connects the robot end effector to an industrial robot such that the industrial robot can move the robot end effector along a composite part as the plasma control unit directs a jet of atmospheric plasma through the plasma jet nozzle toward the composite part to clean the composite part and increase a surface free energy of the composite part.

Systems and methods for improving adhesion of an insulating foam to a molded polymeric insulating structure through use of ozone gas for functionalization of molded polymeric surfaces of an internal cavity of the insulating structure.

The invention relates to a method for treating an elongated object using a plasma process. The method comprises the steps of providing an elongated object in a planar electrode structure, and applying potential differences between electrodes of an electrode structure to generate the plasma process. Further, the method comprises at least partially surrounding the elongated object by a unitary section of the guiding structure, the electrode structure being associated with the unitary section.

This disclosure provides economical and effective methods and apparatus for repairing scratches and scuffs on refillable bottle surfaces that minimally contaminates the bottle during the refurbishing process. In one aspect, the method comprises the steps of: a) adding at least one fluid into the polymeric packaging material such as a bottle to form at least a partially filled packaging material; and b) applying at least one heat source to an exterior surface of the at least partially filled packaging material to form a repaired polymeric packaging material. Apparatus and recycling systems that incorporate this method are also disclosed.

The tube is stretchable. The tube is stretched by applying tension in a longitudinal direction. The tube returns to its short state by releasing the above-described tension applied in the longitudinal direction. A plurality of protrusions are formed on an inner surface of the tube. Each of the plurality of protrusions extends in a circumferential direction. The plurality of protrusions are arranged side by side in the longitudinal direction of the tube. A pitch of the protrusions is less than or equal to 1.5 μm.

Disclosed is a method for manufacturing packaging including a container. The method includes: an operation of forming the container via blow molding or stretch blow molding from a plastics preform, an operation of treating an inner surface of the container, during which a thin barrier layer is formed on the inner surface via plasma-enhanced chemical vapor deposition; an operation of printing on an outer surface of the container, during which ink is deposited on the outer surface to form a decorative and/or informative inscription thereon.

A plug-in connector module for a modular industrial plug-in connector is provided, wherein the plug-in connector module has a housing with a housing surface, wherein the housing consists substantially of plastic, wherein the plug-in connector module has at least one electrical contact element, wherein the housing has at least one contact chamber with a contact chamber surface, wherein the at least one electrical contact element is arranged in the contact chamber, wherein at least a portion of the contact chamber surface and/or at least a portion of the housing surface are/is plasma-modified. A method for producing a plug-in connector module of an industrial plug-in connector is also provided and includes: producing a plastics housing with a housing surface and at least one contact chamber for receiving a contact element, modifying at least a portion of the housing surface and/or at least a portion of the contact chamber surface with an atmospheric pressure plasma with a working gas being fed in.

A method for etching a layer of assembled block copolymer including first and second polymer phases, the etching method including a first step of etching by a first plasma formed from carbon monoxide or a first gas mixture including a fluorocarbon gas and a depolymerising gas, the first etching step being carried out so as to partially etch the first polymer phase and to deposit a carbon layer on the second polymer phase, and a second step of etching by a second plasma formed from a second gas mixture including a depolymerising gas and a gas selected among the carbon oxides and the fluorocarbon gases, the second etching step being carried out so as to etch the first polymer phase and the carbon layer on the second polymer phase.

For producing a dome-shaped element (2) provided with thermal protection for a solid propellant rocket engine, a coupling annular body (4) is arranged in a mold (5) and has a surface (20) that is clean and activated, by an atmospheric-pressure plasma treatment, before depositing a primer layer (26) and an adhesive layer (27) on the surface (20); ablative material is then automatically applied to the adhesive layer and to an area (17) of the mold (5) so as to form a series of superimposed layers (30).
