This study focuses on the deposition and growth mode of rhodium (Rh) on gold (Au) seed nanorods (NRs). Using a combination of scanning transmission electron microscopy imaging, energy-dispersive X-ray spectroscopy, and UV-visible absorption spectroscopy, we show that Rh deposition results in an uneven overlayer morphology on the Au NR seeds, with a tendency for Rh deposition to occur preferenti...
Creating non-equilibrium states of matter with highly unequal electron and lattice temperatures (T(ele)≠T(ion)) allows unsurpassed insight into the dynamic coupling between electrons and ions through time-resolved energy relaxation measurements. Recent studies on low-temperature laser-heated graphite suggest a complex energy exchange when compared to other materials. To avoid problems related t...
Seventy-two crossbred (Large White X Landrace) pigs were used in a 3 X 7 factorial experiment to investigate the response of two strains of boars (strains A and B) and of castrated male pigs (strain B) to seven levels of intake of a single diet (ranging from 5.3 Mcal digestible energy [DE]/d to ad libitum) between 45 and 90 kg live weight. All aspects of growth performance and body composition ...
Antimony cluster thin films have been synthesized by the newly-developed low energy cluster beam deposition technique. Proton-induced X-ray emission analysis shows absence of any foreign impurity even at ppm level. Structural analysis by glancing angle X-ray diffraction indicates presence of rhombohedral Sb along with Sb-oxides. Transmission electron microscopy micrographs for 20 Å and 100 Å fi...
Gold nanoparticle (GNP) can be used as a radiation sensitizer in radiotherapy, and many Monte Carlo simulation studies have focused on this issue. A nanodosimetry biophysics Monte Carlo code NASIC was used in this work to study both the physical and biological radiosensitization effect of GNP in the cell environment under the irradiation of X-ray. GNP-cell models were built in the simulation wi...
Spray deposition of powder suspensions followed by room temperature compression was studied as a method for preparing nanostructured TiO2 films for dye-sensitized solar cells. The structure of the films was analyzed with optical and scanning electron microscopy and the films were applied to dye-sensitized solar cells. Continuous and fast deposition of crack-free 7–14 mm thick films was achieved...
Improved Localization of Energy Deposition in Adaptive Phased-Array Hyperthermia Treatment of Cancer
■ Elevated cell tissue temperature (hyperthermia) due to radio-frequency (RF) energy absorption is known to produce an improved response for malignant tumors in humans when applied in combination with other anticancer modalities. However, clinical studies in thermotherapy have shown the difficulty of localizing RF energy deposition in malignant tissue deep within the body without damaging surro...
