An imprint process comprises the step of aligning a substrate, supported on a first support member, with a template, supported on a second support member. The substrate has at least one essentially plane surface provided with a moldable film. The template has at least one essentially plane surface provided with a relief pattern. The relief pattern is adapted to interact with the moldable film. The process further comprises the step of arranging a sealing gasket between the template and the second support member, such that a pressure cavity is defined by the second support member, the template and the sealing gasket. The process also comprises the step of applying a static gas pressure to the pressure cavity, in order to provide a pressure between the template and the substrate. The pressure is sufficient to form a pattern in the moldable film. An imprint device is also disclosed.

Use of polyunsaturated fatty acid derivatives as medicaments or functional foods. The present invention relates to the use of 1,2-fatty acid derivatives in the treatment or prevention of common diseases whose etiology is based on alterations (of any type) of the cell membrane lipids, for example, changes in levels, in the composition or in the structure of these lipids. In addition, for diseases in which the regulation of lipid composition and of the structure of the membranes (or proteins that interact with membranes) causes the reversion of pathological state.

Systems and methods are disclosed for shaping a laser beam for interaction with a film in which the laser beam travels along a beam path and defines a short-axis and a long-axis. In one aspect, the system may include a first short-axis element having an edge positioned at a distance, d1, along the beam path from the film and a second short-axis element having an edge positioned at a distance, d2, along the beam path from the film, with d2<d1. An optic may be positioned along the beam path between the second element and the film for focusing the beam in the short-axis for interaction with the film. In another aspect, a system may be provided having a mechanism operative to selectively adjust the curvature of one or both of the edges of the short-axis element.

Focused Electric Field Imprinting (FEFI) provides a focused electric field to guide an unplating operation and / or a plating operation to form very fine-pitched metal patterns on a substrate. The process is a variation of the electrochemical unplating process, wherein the process is modified for imprinting range of patterns of around 2000 microns to 20 microns or less in width, and from about 0.1 microns or less to 10 microns or more in depth. Some embodiments curve a proton-exchange membrane whose shape is varied using suction on a backing fluid through a support mask. Other embodiments use a curved electrode. Mask-membrane interaction parameters and process settings vary the feature size, which can generate sub-100-nm features. The feature-generation process is parallelized, and a stepped sequence of such FEFI operations, can generate sub-100-nm lines with sub-100-nm spacing. The described FEFI process is implemented on copper substrate, and also works well on other conductors.

Systems and methods are disclosed for focusing a beam for an interaction with a film deposited on a substrate wherein the focused beam defines a short axis and a long axis.

Systems and methods are disclosed for shaping laser light as a line beam for interaction with a film that may have an imperfect, non-planar surface. The system may include a beam stop that defines an edge; a sensor that measures a distance between a selected point on a surface of the film and a reference plane and generates a signal representative of the measured distance; and an actuator coupled to the beam stop and responsive to the signal to move a portion of beam stop edge. Movement of the beam stop edge portion shifts a corresponding portion of the focused line beam in a direction normal to the reference plane to produce a line beam that more closely conforms to the surface profile of the film.
