We demonstrate modulation of nitric oxide release in solution and in human prostate cancer cells from a thiol functionalized cupferron (TCF) absorbed on hollow gold nanoshells (HGNs) using near-infrared (NIR) light. NO release from the TCF-HGN conjugates occurs through localized surface heating due to NIR excitation of the surface plasmon. Specific HGN targeting is achieved through cell surface...

This paper outlines the development and design of an infrared radiation heating profile controller. The study includes both the theoretical aspects of the design process as well as giving an overview of the practical facets involved. The controller was subjected to comparative testing with a proportional control model, in order to observe its performance and validate its effectiveness. The conc...

Vertical cracks are among the most problematic types of defects from the thermal nondestructive testing (NDT) point of view. Nowadays, the fast thermal inspection techniques most commonly utilize infrared cameras and pulsed heating provided by flash lamps. The flash lamps illuminate the whole surface of a sample, and the resulting heat flow is mostly perpendicular to the surface. Therefore, the...

Aims. We study the LMC interstellar medium in the field of the nebula N157B, which contains a supernova remnant, an OB association, ionized gas, and high-density dusty filaments in close proximity. We investigate the relative importance of shock excitation by the SNR and photo-ionization by the OB stars, as well as possible interactions between the supernova remnant and its environment. Methods...

This collaboration has recently shown that infrared excitation can drive decomposition reactions of molecules on the surface of gas-phase transition metal clusters. We describe here a significant extension of this work to the study of bimolecular reactions initiated in a similar manner. Specifically, 10 we have observed the infrared activated CO oxidation reaction (CO (ads) + O (ads) → CO 2(g))...

Indium tin oxide (ITO) films have been deposited onto glass substrates by ifmagnetron sputtering without insitu substrate heating. The as-deposited films have an electrical resistivity of 5x1O a-cm, visible transmittance of about 85%, and infrared (IR) reflectance of above 80% at 5 jim. The effect of sputtering parameters on the deposition rate and the electrical and optical properties of ITO f...

In thin-layer electrodeposition the dissipated electrical energy leads to a substantial heating of the ion solution. We measured the resulting temperature field by means of an infrared camera. The properties of the temperature field correspond closely with the development of the concentration field. In particular, we find that the thermal gradients at the electrodes act similar to a weak additi...
