There is provided a method of making a fluidic system that comprises assembling a fluidic system comprising a first plate, a second plate and a membrane disposed between the first plate and the second plate; applying laser energy to the fluidic system to cause the first plate, the second plate and the membrane to melt at bonding areas; and allowing the bonding areas to cool down such that the first plate, the second plate and the membrane are bonded together.

The invention concerns a film based on a binary polymer composition having at least a first polymer and a second polymer. The film is oriented by extruding and stretching the film in at least the machine direction. The glass-transition temperature (Tg) of the first polymer is greater than the orientation temperature and the glass-transition temperature (Tg) of the second polymer is lower than the orientation temperature. Furthermore, a method and use related thereto are described.

Disclosed herein are solution-based additive manufacturing inks comprising a polymer, a volatile solvent compound, and a nonsolvent compound. With current additive manufacturing techniques, a wide range of functionally innovative polymers are left without the ability to be used in additive manufacturing. Improved additive manufacturing techniques to process advanced functional polymers are desirable. The disclosed ink is operable to render any chosen polymer useable in additive manufacturing methods. The composition of the disclosed ink allows for a phase inversion to occur to transition the ink from a liquid ink to a solid manufactured structure. Also disclosed herein are devices for additive manufacturing of the ink and methods for making the same.

Provided is a biodegradable resin composition that exhibits excellent biodegradability even in a molded product having a large thickness, has excellent mechanical properties, and is economically advantageous, and a molded product using the same. The molded product is provided using an inorganic substance powder-containing biodegradable resin composition including: a biodegradable resin and an inorganic substance powder in a mass ratio of 10:90 to 70:30, in which the biodegradable resin is a cellulose acetate-based resin and the inorganic substance powder is heavy calcium carbonate.

The present invention relates to polymer compositions comprising at least one basic additive, and processes comprising at least one process step to obtain the polymer composition or articles comprising the polymer composition. The polymer composition generally displays an enhanced biodegradability.

A bone fixation device made of polysaccharide particles or microspheres fused into a solid structure is provided herein. The bone fixation device may be in the form of an orthopedic screw, orthopedic pin, or orthopedic plate. Methods of making the bone fixation devices described herein are provided as are methods of treating patients in need of bone repair or replacement by implanting a bone fixation device described herein in the patient at a site of bone damage, ligament damage, or bone deformity.

Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.

A manufacturing process and the semi-finished product of thermoplastic material obtained therefrom, for obtaining products with aesthetic patterns which can be perceived in semitransparency also in depth is disclosed. The process includes: (i) producing at least two initial elements of thermoplastic material with even but different aesthetic patterns, having a different concentration of the dominating coloring, at least the dominating coloring being of the bleeding type in the specific thermoplastic material; (ii) shaping the two initial elements into strips or loaves being of a submultiple width, not below ⅕ of a characteristic dimension of the desired finished product; (iii) inserting at least two of the strips or loaves having different concentration of the dominating coloring, into a workform, arranging them side by side according to a direction of side-by-side arrangement; and (iv) undergoing pressure and heat to allow the melting and hardening of the thermoplastic material into a single body.
