This work aims to investigate and characterize the photo-ignition phenomenon of MWCNT/ferrocene mixtures by using a continuous wave (CW) xenon (Xe) light source, in order to find the power ignition threshold by employing a different type of light source as was used in previous research (i.e., pulsed Xe lamp). The experimental photo-ignition tests were carried out by varying the weight ratio of ...

This paper describes close-range calibrations of multiple Sony Alpha NEX 5 consumer digital cameras with multiple interchangeable lenses. The standard physical parameter set and a standard parameter set with affinity and orthogonality terms are tested with both block-invariant and photo-invariant principal point parameters. The impact of the parameter sets is analysed to determine the effective...

tungsten trioxide nanoparticles with monoclinic structure and average particle size about 80 nm were prepared by the spray pyrolysis method. wo3 nanorods with hexagonal structure and average dimension about 15 × 100 nm were synthesized in gram quantities by modified hydrothermal method at lower temperature and shorter reaction time in comparison to the previous research. photo degradation of co...

The accelerating integration of microwave and optical components in modern optoelectronic systems stimulates comprehensive investigations of device operation and efficiency. This paper studies the optoelectronic conversion capabilities of sub-micron GaAs active devices in response to ultra-short illumination pulses. The physical phenomena involved in the photo-electronic effects are appropriate...

zno and mn-zno nano powders were prepared by the sol-gel auto combustion method. the products were characterized by x-ray diffraction (xrd), energy dispersive analysis of x-ray (edx) and scanning electron microscopy (sem). structural and morphological properties of nano particles were investigated and the average crystalline size of zno and mn-doped zno was obtained 44 and 51 nm, respectively. ...

This review article is a comprehensive report on vanadium oxides which are interesting materials for environmental applications. Therefore, general overview of and its related presented in the first two parts. Afterwards, physical properties binary ternary single mixed valence states described such as their structural, optical, electronic properties. Finally, use these photochemical processes a...

Quantum computers promise to increase greatly the ef®ciency of solving problems such as factoring large integers, combinatorial optimization and quantum physics simulation. One of the greatest challenges now is to implement the basic quantumcomputational elements in a physical system and to demonstrate that they can be reliably and scalably controlled. One of the earliest proposals for quantum ...

Isoprene is globally the most ubiquitous nonmethane hydrocarbon. The biogenic emission is found in abundance and has a propensity for SOA formation in diverse climates. It is important to characterize isoprene SOA formation with varying reaction temperature. In this work, the effect of temperature on SOA formation, physical properties, and chemical nature is probed. Three experimental systems a...
