The invention provides a method for manufacturing a 3D item (1) by means of 3D printing. The method comprises the step of depositing, during a printing stage, 3D printable material (201) to provide 3D printed material (202), wherein the 3D printable material (201) comprises a core-shell filament (320) comprising (i) a core (321) comprising a core material (1321) having one or more of a core glass temperature Tg1 and a core melting temperature Tm1 and (ii) a shell (322) comprising a shell material (1322) having one or more of a shell glass temperature Tg2 and a shell melting temperature Tm2, wherein one or more of the shell glass temperature Tg2 and the shell melting temperature Tm2 is lower than one or more of the core glass temperature Tg1 and the core melting temperature Tm1. The method further comprises the step of heating, during a finishing stage, the 3D printed material (202) to a temperature equal to or higher than one or more of the shell glass temperature Tg2 and the shell melting temperature Tm2, and equal to or lower than one or more of the core glass temperature Tg1 and the core melting temperature Tm1.

Disclosed herein are embodiments of a plasma treatment system and methods for utilizing directed plasma to reduce instances of gas venting and leaking of contents from plastic bottles due to scratches occurring on sealing interfaces of the bottles and closures. In an embodiment, a plasma treatment system for repairing scratches applied to PET bottles comprises one or more plasma nozzles disposed along a bottle filling line and a plasma being issued by the plasma nozzles to repair the scratches. The plasma nozzles are arranged into a configuration that uniformly distributes plasma to all parts of a neck finish comprising the PET bottles. The plasma treatment of the PET bottles is performed prior to capping of the bottles. In an embodiment, the plasma treatment is performed after filling the bottles with contents so as to avoid a risk of scratches from misaligned filling tubes.

The present invention relates to pharmaceutical dosage forms, for example to a tamper resistant dosage form including an opioid analgesic, and processes of manufacture, uses, and methods of treatment thereof.

Methods for generating patterned nanoparticle assemblies in thin films of supramolecular nanocomposites are provided that allow control over microdomain morphology, periodicity, and orientation by tuning the assembly kinetics and pathways of the system. Directed self-assembly (DSA) of block copolymers (BCPs) with nanoparticles formed on lithographically-patterned templates produce patterned supramolecular nanocomposite films and patterns of nanoparticles. DSA may be used to guide the formation of concentric rings with radii spanning approximately 150 nm to 1150 nm and ring widths spanning about 30 nm to 60 nm, for example. When plasmonic nanoparticles are used, ring nanodevice arrays can be fabricated in one step, and the completed devices produce high-quality orbital angular momentum (OAM).

An apparatus, method, or platter for modifying mesa sidewalls of a template by cleaning or coating the mesa sidewalls. In which the template has a pattern area on a first surface of a mesa. Mesa sidewalls surround the first surface of the mesa. The mesa sidewalls are exposed to a gas. The gas modifies the mesa sidewalls. Resistance to the flow of gas towards the pattern area is provided.

A device and method for smoothing a surface of an article formed at least partially from plastic, in particular a component of a motor vehicle, is provided. The method includes arranging the article in a vacuum-tight chamber, reducing the pressure in the chamber to a partial vacuum of not more than 50 kPa, in particular not more than 34 kPa, and admitting acetone into the chamber. Some of the acetone is vaporized and the vapor is precipitated on the surface of the article. In one form, the precipitated vapor acts on the article for at least 1 minute. The method further includes opening the chamber, so that at least the ambient pressure prevails in the chamber and removing the article from the chamber.

A molded article of a carbon fiber composite material includes at least carbon fibers and a resin composition. The molded article of a carbon fiber composite material is characterized in that the surface roughness Ra thereof is 0.01-2 ?m and in that the tensile shear adhesive strength (F0) thereof when a metal has been adhered to the surface thereof via an adhesive layer that contains an epoxy compound and is 0.1-3 mm thick is 10-40 MPa.
