摘要： A hologram element for broadband shaping of electromagnetic waves and a related system are disclosed. The hologram element has a dispersive surface with a surface height profile that is configured to spatially modulate at least one of an amplitude or a phase of transmitted electromagnetic waves having a bandwidth defined by a start frequency f1 and a stop frequency f2. The surface height profile is further configured to maximize a rate of one of a phase shift or a delay variation at said bandwidth via steps comprised in the dispersive surface, each step having a step height the electrical length of which is a multiple of N+q wavelengths at the start frequency f1 and M multiple of wavelengths at the stop frequency f2.

摘要： The present invention is directed to a method for producing a condensed phase of a silk fusion protein, the method comprising the steps of preparing a solution of a silk fusion protein in an aqueous medium and concentrating the silk fusion protein in the aqueous medium, wherein the fusion protein is isolated from a recombinant production host and comprises a silk-like protein sequence and two separate non-silk terminal module sequences, such as cellulose binding modules, SpyCatcher domains, tenth type III module of Fibronectin, gamma-crystallin D, flanking the silk-like protein sequence; wherein the method is performed so that the silk fusion protein is not precipitated and subsequently dissolved to the aqueous medium. The present invention is also directed to using such fusion proteins as adhesives.

摘要： Colored lyocell type fibers comprising respun coloured recycled fibers and method of producing the same. According to the method a raw-material of colored recycled textile fibers is provided and dissolved in an ionic liquid to provide a spinning dope. By spinning the dope using dry jet-wet spinning colored respun textile fibers can be manufactured. The invention provides for the simultaneous recycling of cellulose fibers and dyes from dyed cotton waste in the form of dyed lyocell fibers.

摘要： The invention enables the certification of a measurement result of a measuring device. A measuring device arranged in connection with a data security module according to the invention takes under processing a measurement result produced using a measuring instrument of the measuring device (501). The measuring device associates a digital calibration certificate associated with a public key corresponding to a secret key stored in a key storage with the measurement result taken under processing (502). The measuring device digitally signs the associated measurement result using a signing function of the data security module and the secret key stored in the key storage (503).

摘要： The present invention relates to a cold-crystallizing material having high latent heat, and a method of using the present material for heat storing. The material of the invention comprises of a phase change material and an additive which is preferably a hydrophilic polymer matrix. Preferably, sugar alcohols, such as erythritol or D-mannitol, are used as the phase change material. The polymer of the invention is preferably cross-linked and ionic, i.e. a polyelectrolyte. PCM stores a high amount of heat energy while melting and releases the stored thermal energy by cold-crystallization. Compared to previously studied cold-crystallizing materials, the latent heat of the cold-crystallizing material of the invention is considerably higher, and cold-crystallization is more repeatable in successive melting-crystallization cycles. The material can be used for heat storing. Heat energy can be released from the material by a heat pulse on demand. The method is particularly suitable for long-term heat storing.

摘要： The invention relates to a rotatable, plungeable and free path travelable non-consumable tool (5) for production of a channel (2) and a weld joint (1). The tool (5) comprises a shoulder and a probe, the shoulder having a surface facing the material(s) of components (3) to be processed. The shoulder and the probe are arranged to have a simultaneous and synchronized action in the materials of at least two components (3) to be processed. The shoulder facing the at least two components (3) to be processed has a system of scrolls shaped to have an inward action and an outward action on the at least two components (3) to be processed. The probe has a cylindrical or conical surface having a top zone, provided with a profile having a push-up action on the components (3) to be processed in a direction towards the shoulder. The top zone ends at or in the vicinity of a bottom zone provided with a profile having a push-down action on the components (3) to be processed in a direction towards the tip. The tool (5) enables the production of a channel (2) and a weld (1), between said at least two components (3), in one single action.
