摘要:
The invention relates to a method for photo-embossing a monomer-containing layer for obtaining a photovoltaic cell, a light emitting diode (LED), or a light emitting electrochemical cell (LEC) by the steps of: (a) optionally providing one or more layers onto the surface of the monomer-containing layer, (b) irradiating through a mask a layer consisting of a homogeneous blend of at least two different compounds, at least one of which is a polymerizable monomer, to obtain a monomer-containing layer with exposed and non-exposed areas; (c) optionally providing further layers onto the surface of the monomer-containing layer; (d) expanding the exposed or the non-exposed areas by diffusing at least one of the monomers to the exposed areas to obtain a corrugated surface of the layer; or interchanging steps c) and d).
摘要:
The present invention relates to a data carrier comprising an information layer (1) itself comprising a specific area (4) able to deliver a first optical signal and a second optical signal when illuminated by a light source. Said data carrier also comprises an additional layer (2) able to deliver an electrical signal when illuminated by the second optical signal, said electrical signal corresponding to a predetermined pattern. The combination of the first optical signal and of the electrical signal forms a cryptographic key that is required to decrypt encrypted data contained in the information layer. This invention is particularly relevant to the read out of data stored on optical discs of the Read Only Memory type.
摘要:
A composition for forming a semiconducting device includes an organic semiconducting material, an agent capable of inhibiting and/or preventing dewetting, and an additional substance, wherein the additional substance is provided in an amount capable of preventing initial crystallization of the composition and reducing the melting point or glass transition temperature of the composition below the melting point or glass transition temperature of the organic semiconducting material. The additional substance may be naphthalene, phenylnaphthalene, anthrance, or diphenylanthrance.
摘要:
The present invention provides a method of forming a semiconducting device comprising an organic semiconducting material, which method comprises: heating a composition comprising the organic semiconducting material to a temperature at or above the melting point or glass transition temperature of the composition to form a melt; cooling the melt to a temperature below the melting point or glass transition temperature of the composition; and wherein a first substance or object capable of inhibiting and/or preventing dewetting is adjacent the composition before or during heating, or the composition further comprises an agent capable of inhibiting and/or preventing dewetting.

Disclosed is a semiconductor device (1) for determining NO concentrations in fluids such as exhaled breath. The device (1) typically comprises a pair of electrodes (18) separated from each other to define a channel region (16) in an organic semiconductor (14), a gate structure (10) for controlling said channel region, and a receptor layer (22) at least partially overlapping said channel region, said receptor layer comprising a porphine or phtalocyanine coordination complex including a group III-XII transition metal ion or a lead (Pb) ion for complexing NO. Such a semiconductor device is capable of sensing NO concentrations in the ppb range.

This invention relates to a device (100) to be worn by or attached to an animal (102) for indicating the physiological status of the animal. At least one measuring device is used for measuring the physiological state of said animal. The resulting physiological data are regularly compared to at least one threshold value when evaluating the current physiological status of said animal. Based thereon, indication means indicates the current physiological status of said animal.
