摘要:
A radiation detection system can include a scintillating member including a polymer matrix, a first scintillating material, and a second scintillating material different from the first scintillating material and at least one photosensor coupled to the scintillating member. The radiation detection system can be configured to receive particular radiation at the scintillating member, generate a first light from the first scintillating material and a second light from the second scintillating material in response to receiving the particular radiation, receive the first and second lights at the at least one photosensor, generate a signal at the photosensor, and determine a total effective energy of the particular radiation based at least in part on the signal. Practical applications of the radiation detection system can include identifying a particular isotope present within an object, identifying a particular type of radiation emitted by the object, or locating a source of radiation within the object.

The invention relates to a composite gel polymer Li-ion battery and its producing method. The Li-ion battery cell includes a three-layer composite layer of positive electrode current collector, positive electrode active material and gel polymer electrolyte obtained by a two-layer one-step coating process; a two-layer composite layer of negative electrode current collector and negative electrode active material obtained by a single-layer coating process or a negative electrode two-layer composite layer coated with a little polyurethane adhesive(s) on the surface. The gel polymer Li-ion battery cell is obtained by laminating the resultant two composite layers. Its producing method includes: A) coating directly the composite positive electrode current collector film which has a bottom layer of polyester and a surface layer of metal (aluminum, copper, silver or gold) foil with a positive electrode active material and a gel polymer electrolyte by a two-layer one-step coating process; B) coating the composite negative electrode current collector film which has a bottom layer of polyester and a surface layer of metal (aluminum, copper, silver or gold) foil with a Li battery negative electrode active material; C) laminating A and B layers, heating and curing, leading out electrode lugs, and thereby obtaining gel polymer Li-ion battery cells; D) vacuum-packing the battery cells, and thereby obtaining a gel polymer Li-ion battery. The gel polymer Li-ion battery cell has a small thickness and a compact structure, and is laminated closely and easy for preparation and industrial automatic production. And a plurality of groups of cells can be laminated and cut to a desirable geometrical shape, so as to obtain a Li battery pack in a desired shape. The Li battery prepared by the method has a uniform structure, a low internal resistance, a high uniformity, a good unity, and a high safety.

摘要:
Industrial combustion facilities are integrated with greenhouse gas-solidifying fertilizer production reactions so that CO2, CO, NOx, and SOx emissions can be converted prior to emission into carbonate-containing fertilizers, mainly NH4HCO3 and/or (NH2)2CO, plus a small fraction of NH4NO3 and (NH4)2SO4. The invention enhances sequestration of CO2 into soil and the earth subsurface, reduces N03− contamination of surface and groundwater, and stimulates photosynthetic fixation of CO2 from the atmosphere. The method for converting CO2, CO, NOx, and SOx emissions into fertilizers includes the step of collecting these materials from the emissions of industrial combustion facilities such as fossil fuel-powered energy sources and transporting the emissions to a reactor. In the reactor, the CO2, CO, N2, SOx, and/or NOx are converted into carbonate-containing fertilizers using H2, CH4, or NH3. The carbonate-containing fertilizers are then applied to soil and green plants to (1) sequester inorganic carbon into soil and subsoil earth layers by enhanced carbonation of groundwater and the earth minerals, (2) reduce the environmental problem of NO3−runoff by substituting for ammonium nitrate fertilizer, and (3) stimulate photosynthetic fixation of CO2 from the atmosphere by the fertilization effect of the carbonate-containing fertilizers.

摘要:
The invention describes a polymer that is composed of a fluoropolymer modified with a UV absorber. The UV absorber is grafted to the polymeric backbone of the fluoropolymer. Optionally, a HALS can also be grated to the polymeric backbone of the fluoropolymer. Incorporation or the absorber or stabilizer helps to reduce degradation of underlying layers such as an encapsulant while still allowing useful light energy to pass through the layers to a device, such as a photovoltaic device.
