Abstract: Charge splitting networks for optoelectronic devices may be fabricated using a nanostructured porous film, e.g., of SiO2, as a template. The porous film may be fabricated using surfactant temptation techniques. Any of a variety of semiconducting materials including semiconducting metals and metal oxides (such as TiO2, CdSe, CdS, CdTe, or CuO) may be deposited into the pores of the porous template film. After deposition, the template film may be removed by controlled exposure to acid or base without disrupting the semiconducting material leaving behind a nanoscale network grid. Spaces in the network grid can then be filled with complementary semiconducting material, e.g., a semiconducting polymer or dye to create a exciton-splitting and charge transporting network with superior optoelectronic properties for an optoelectronic devices, particularly photovoltaic devices.

Abstract: The invention uses apparatus, methods or systems, e.g., fine pore diffusers (18), to saturate ground water with a gas, preferably oxygen, but also possibly methane, air, inert or noble gasses and/or carbon dioxide. The pore diffusers (18) can be in a ring of aeration injection wells (16) in a large concentric ring around a production well. By increasing the dissolved oxygen level in the ground water, undesirable constituents such as iron or arsenic are lowered in concentration. Methods can be employed to optimize the ground water treatment by injection of other substances, such as iron, as well as predict, model, design, monitor and maintain the treatment process.

Abstract: Quasi-phasematching design to provide an approximation to a desired spectral amplitude response A(f) is provided. An initial phase response ?(f) corresponding to A(f) is generated. Preferably, d2?(f)/df2 is proportional to A2(f). Alternatively, ?(f) can be a polynomial in f. A function h(x) is computed such that h(x) and H(f)=A(f)exp(i?(f)) are a Fourier transform pair. A domain pattern function d(x) can be computed by binarizing h(x) (i.e., approximating h(x) with a constant-amplitude approximation). In some cases, the response provided by this d(x) is sufficiently close to A(f) that no further design work is necessary. In some embodiments of the invention, the need for binarization can be reduced or eliminated by providing amplitude modulation of the effective nonlinearity.

Abstract: A stripper assembly strips a media sheet from a photoreceptor belt. A support bracket supports a stripping finger base which includes a multiplicity of attached stripping fingers. The support bracket is fixed proximate to the photoreceptor belt in a media stripping position. Each stripping finger has a protruding distal stripping end extending toward the photoreceptor belt to form a gap therewith. The magnitude of the stripping finger-photoreceptor belt gap is controlled by adjusting the position or spacing of the finger base with respect to the support bracket. The support bracket pivots about an inboard pivot axial. The opposite support bracket outboard end is releasable, thus enabling the support bracket to pivot away from the photoreceptor belt.

Various approaches for binarization are provided. The availability of multiple binarization approaches is helpful for making design trades (e.g.
