A novel BODIPY-containing organic small molecule is synthesized and employed as a down-converting layer on a commercial blue light-emitting diode (LED). The resulting hybrid device demonstrates white-light emission under low-current operation, with color coordinates of (0.34, 0.31) and an efficacy of 13.6 lm/W; four times greater than the parent blue LED.

We describe the design and implementation of a reconfigurable highspeed interface for IEEE 1394 Firewire and measurements obtained with this system. For the physical and link layers we use a commercial chip-set. FieldProgrammable Gate Arrays on the PCI Pamette and a secondary FireLink board are used to implement a simple transaction layer interfacing the link layers to the host CPU.

Nitrogen doped graphitic layer encased cobalt (N-C@Co) nanoparticles, as novel non-precious-metal catalysts for the oxygen reduction reaction (ORR), were fabricated by a facile method using cyanamide and cobalt nitrate as precursors. The N-C@Co catalysts exhibited comparable catalytic performance, better stability and improved methanol tolerance towards the ORR than those of the commercial Pt/C...

We report here the complete genome sequence of an avian metapneumovirus (aMPV) isolated from a tracheal tissue sample of a commercial layer flock. The complete genome sequence of aMPV-A/chicken/Brazil-SP/669/2003 was obtained using MiSeq (Illumina, Inc.) sequencing. Phylogenetic analysis of the complete genome classified the isolate as avian metapneumovirus subtype A.

Velocity overshoot of inversion layer electrons and holes is studied experimentally and analytically in special test structures with nominally uniform electric field. The data were used to calibrate energy relaxation parameters in a commercial simulator MEDIC1 ver. 2.0. We propose an analytical model for velocity overshoot and show that it agrees well with experimental data. The amount of hole ...

Five commercial preparative layer chromatography (PLC) plates precoated with silica gel layers 1 mm thick were compared on the basis of theoretical plate number (N) and resolution (R) by developing a test dye mixture with the same mobile phase over a constant distance with dye loadings of 1.0–5.0 μg per zone. It was found that the best performance, on the basis of N and R data, was obtained fro...

Results of internal friction measurements on the commercial aluminum-magnesium alloys 5052,5086 and 5486 are reported here over the temperature range 50 mK to 300 K, and compared with published data on alloy 5056. Effects of heat treatment and explosive bonds on the internal friction are evaluated. The quality factor of proposed multi-layer aluminum-alloy spherical resonant-mass detectors of gr...

Mycoplasma gallisepticum (MG) is a reproductive/respiratory disease in poultry implicated in suboptimum egg production and decreased hatchability. Commercial layer hens raised in a controlled environment were inoculated with the S6 strain of MG at 10 wk of age. Egg production and selected egg and egg quality parameters were quantitated over the entire lay cycle for inoculated and control birds....

Multilayer thin-film PZT diaphragm has been designed and modeled. Commercial Finite element software, ANSYS was implemented to model the diaphragm. This multi-layer diaphragm can be used as both sensor and actuator. A simplified model is introduced to reduce the CPU time. Dynamic characteristics of the multilayer diaphragm have been investigated. The important parameters of the multilayer PZT d...

In this study, a solid acid was prepared by the sulfonation of surface modified α-zirconium phosphate (ZrP) single-layer nanosheets (SO3H@ZrP), and the prepared solid acid was investigated for the esterification of oleic acid with methanol to produce biodiesel. For comparison, liquid H2SO4 and commercial Amberlyst® 15 catalyst were also evaluated for the same reaction under the same conditions....
