Summary: Thermal drilling is a chip-less hole-forming process affected by rotational speed, feed rate, and cone angle. This study investigates the effect of variations in friction drilling parameters on the surface roughness values and dimensions of a thermally induced bushing. Response surface methodology was used to optimize the drilling parameters, and the experimental results agree with the presented models. The optimal parameters for the lowest surface roughness value are a rotational speed of 1250 rpm, a feed rate of 200 mm/min, and a cone angle of 45 degrees.

Summary: When a metal nanoparticle absorbs light, it undergoes a series of relaxation processes that lead to transient modifications in its optical response. By using time-resolved spectroscopy experiments, it was shown that the transient optical response could be attributed to internal thermalization processes within the nanoparticle, and the effects of electron and ionic lattice heating were quantitatively studied. The study demonstrated the possibility of selectively probing electronic or lattice dynamics by choosing specific probe wavelengths, and showed that the timedependent spectral shape of transient extinction cross-section changes was successively dominated by electron and lattice heating effects.

Summary: Metal-organic frameworks (MOFs) have shown promise for developing next-generation solid-state devices with applications in optics. However, the difficulty in growing large, high-quality MOF single crystals has hindered the implementation of functional devices. By controlling the synthesis conditions, researchers successfully produced large, noncentrosymmetric MOF single crystals with a unique shape and high surface area. These crystals exhibited anisotropic absorption, and the observed size dependence in optical anisotropy was correlated with the preferred orientation of the molecules. This work opens up possibilities for developing optical polarization switches based on MOFs.

Summary: In this study, Cu2S/CdS thin-film was deposited on an FTO substrate using the spray-pyrolysis technique. Field-emission scanning electron microscopy (FESEM) images showed that the thin-films were mono-dispersed and nearly spherical, with an average size ranging from 50 nm to 100 nm, which increased with increasing temperature. The performance of Sn/Cu2S/CdS/FTO/glass hetrojunction diodes was analyzed through I-V measurement, and parameters such as potential height, leakage current, ideality factor, and series-shunt resistance were calculated using different models. It was observed that the ideality factor decreased from 1.31 to 1.12 and the potential height increased from 0.79 to 0.86 with increasing temperature, according to the thermionic emission model. The estimated values of the diode parameters from these three different methods were in good agreement.
