1d2d, 1d3d, 2d2d Cyclone Fractional Efficiency Curves for Fine Dust
The prediction of emission concentrations from cyclone collectors is integral to the permitting of agricultural facilities including cotton gins. One method for predicting emission concentrations utilizes fractional efficiency curves. Fractional efficiency curves (FEC’s) were developed for 1D2D, 1D3D, and 2D2D cyclone designs. The procedure used to develop these new FEC’s incorporated log-norma...
متن کاملPerformance Characteristics for the 1D2D, 2D2D, 1D3D and Barrel Cyclones
The results of performance testing of four different cyclone designs are included in this paper. The 1D3D, 2D2D, 1D2D and Barrel cyclone designs are cyclone designs typically used to abate particulate matter (PM) emitted by cotton gins. The PM used for testing included three types of cotton gin trash (with and without lint fiber) and fly ash. The performance tests were conducted at different to...
متن کاملThe Need for Bulk Heterojunctions
Nanostructured phase-separated blends, or bulk heterojunctions, of conjugated polymers and fullerene derivatives form a very attractive approach to large-area, solid-state organic solar cells.The key feature of these cells is that they combine easy processing from solution on a variety of substrates with good performance. Efficiencies of up to 5% in solar light have been achieved, and lifetimes...
متن کاملReticulated heterojunctions for photovoltaic devices.
Herein we present a molecular self-assembly process on the surface of transparent electrodes that yields a new type of organic semiconductor device structure: the donor deposits as supramolecular cables, and the acceptor subsequently infiltrates this network. This process results in a donor–acceptor interface that is interwoven at the nanoscale. When incorporated into photovoltaic devices, such...
متن کاملCharacterization of silicon heterojunctions for solar cells
Conductive-probe atomic force microscopy (CP-AFM) measurements reveal the existence of a conductive channel at the interface between p-type hydrogenated amorphous silicon (a-Si:H) and n-type crystalline silicon (c-Si) as well as at the interface between n-type a-Si:H and p-type c-Si. This is in good agreement with planar conductance measurements that show a large interface conductance. It is de...
