Comparison of absorption spectroscopy results with a theoretical model of 16-65-nm CTAB-stabilized gold nanorods
Dane BadawczeFigure and data present theoretical and experimental spectroscopy results of 16-65-nm CTAB-stabilized gold nanorods measured in a water solution. The theoretical curve characteristic corresponds with experimental data obtained from a spectrophotometer Thermo Fisher Scientific Evolution 220 calibrated to a water-filled cuvette. The visible discrepancies...

Differential Evolution algorithm used for maximization of energy conversion of size and length of laser-irradiated gold nanorods optimization
Dane BadawczeThe Differential Evolution algorithm was used to solve a model that describes electromagnetic energy conversion, here: into heat. Results reveal the optimized size and length that should be used for maximization of energy conversion. The selected wavelengths for optimization were 465 nm, 532 nm, 640 nm, 808 nm, and 980 nm.

Maximum temperature of 0.5-W infrared laser-Illuminated gold nanorod platforms
Dane BadawczeData concern a system consisted of two pieces of borosilicate glass surrounded by air and joined together by a transparent glue, which is to serve as a thermal transducer. On the top and bottom sides of the smaller piece, gold nanorods are dislocated. Glass is prepared here due to its high transparency, facilitating heat to be produced within the system....
