摘要:
The present teachings relate to an organic electroluminescent transistor with improved light-emission characteristics. More specifically, the present organic electroluminescent transistor has an emissive ambipolar channel including at least one layer of an n-type semiconductor material, at least one layer of a p-type semiconductor material, and at least one layer of an emissive material arranged between the layers of the p-type and n-type semiconductor materials, where the multilayer emissive ambipolar channel includes, among various layers, a layer of a p-type semiconductor material comprising a benzothieno-benzothiophene compound, and/or a layer of an emissive material comprising a blend material that includes an organic carbazole derivative as the host matrix compound and an iridium complex as the guest emitter.

Described is a portable gamma camera comprising a containment body (2), a scintillation measuring structure (3) housed in the containment body (2), a collimator (4) associated with the measuring structure (3), a display (5) positioned on the containment body (2) and an electronic controller unit (6), operating between the measuring structure (3) and the display (5) for generating on the display (5) images representing the radiation intercepted by the measuring structure (3).
摘要:
A method for obtaining a scintillation body comprising the steps of readying a matrix (3) of binding material within which is present a plurality of scintillation crystals (2), obtaining a plurality of channels (16) within the matrix (3) and around the crystals (2) and inserting metallic material (9) having a high atomic number and high density between mutually adjacent scintillation crystals (2) without separating the scintillation crystals (2) from the matrix (3) of binding material.
摘要:
A scintillation device with high resolution comprises a detection unit (3) to convert into light radiation an ionising radiation originating from a source under examination and a collimator (2) made of a material with high atomic number and comprising a plurality of grids (4), said grids (4) co-operating with each other in mutually sliding fashion in a transverse direction to the direction of detection (R) to provide a partial coverage of the detection unit (3) in such a way as to expand and reduce in an adjustable manner a surface area of the detection unit (3) offered to said radiation.
摘要:
An injectable apatite cement, in which the calcium in the a phase is partially substituted with strontium, and in which tricalcium phosphate in the β phase is also present is described. Also described is a method for its preparation and its use in bone regeneration, in particular in vertebroplasty, in kyphoplasty, and in pathologies characterized by a loss of bone substance.
摘要:
The invention relates to a so-called zero emission 'AST-CNR/ITM system' modular plant for removal of pollutants from flue gases produced by industrial processes. The plant comprises prefabricated modular elements with programmed and automatic operation, easy to mount and assemble on site without undergoing expensive plant stoppage. Each module or 'reaction tower' comprises a plurality of sections vertically arranged on top of one another, which carry out the following functions: Removal of particulate matter with treatment and removal of chemical pollutants, such as heavy metals, chlorides, fluorides Treatment and removal of SOx Treatment and removal of NOx Capture of CO 2 Production of hydrogen Production of methanol The various sections may be combined according to the requirements of the plant and of the flue gases to be treated.
