Abstract: An electromagnetic transducer includes a magnetic assembly and a coil assembly. The magnetic assembly may include an inner magnet subassembly and an outer magnet subassembly. The inner magnet subassembly and the outer magnet subassembly each have a plurality of axial magnets arranged in a stacked configuration with a spacer disposed between vertically adjacent axial magnets. The coil assembly includes an inner coil subassembly and an outer coil subassembly. The inner coil subassembly is disposed between the inner magnet subassembly and the outer magnet subassembly, and the outer coil subassembly is disposed around the outer magnet subassembly. The coil assembly and the magnetic assembly are configured to move relative to each other.

Abstract: InGaN/GaN quantum layer nanowire light emitting diodes are fabricated into a single cluster capable of exhibiting a wide spectral output range. The nanowires having InGaN/GaN quantum layers formed of quantum dots are tuned to different output wavelengths using different nanowire diameters, for example, to achieve a full spectral output range covering the entire visible spectrum for display applications. The entire cluster is formed using a monolithically integrated fabrication technique that employs a single-step selective area epitaxy growth.

Abstract: A method of modulation of synthesis capacity on and cleavage properties of synthetic oligomers from solid support is described. The method utilizes linker molecules attached to a solid surface and co-coupling agents that have similar reactivities to the coupling compounds with the surface functional groups. The preferred linker molecules provide an increased density of polymers and more resistance to cleavage from the support surface. The method is particularly useful for synthesis of oligonucleotides, oligonucleotides microarrays, peptides, and peptide microarrays. The stable linkers are also coupled to anchor molecules for synthesis of DNA oligonucleotides using on support purification, eliminating time-consuming chromatography and metal cation presence. Oligonucleotides thus obtained can be directly used for mass analysis, DNA amplification and ligation, hybridization, and many other applications.
