Summary: Nitrogen- and oxygen-doped fluorescent carbon dots (NOFCDs) were prepared using a hydrothermal carbonization technique with aqueous ammonia and Garcinia mangostana plant extract as nitrogen and carbon sources, respectively. The synthesized NOFCDs were characterized using various microscopic and spectroscopic techniques. The study revealed that NOFCDs exhibited excitation-dependent fluorescent emission and absorption with the strongest emission peak at 405 nm when excited at 320 nm. The NOFCDs were spherical in shape with a particle size of 3.58 nm. The presence of nitrogen and oxygen doping on the NOFCDs' surface was confirmed through XPS, FTIR, and EDS investigations. Additionally, the NOFCDs showed excellent catalytic activity in the detoxification of methylene blue when treated with NaBH4. Overall, this research highlighted the potential of green-synthesized NOFCDs for catalytic and environmental remediation applications.

Summary: Light beams possess three types of angular momentum, namely spin angular momentum, extrinsic orbital angular momentum, and intrinsic orbital angular momentum. The interaction between these momenta leads to the spin-orbit interaction of light and topological effects. This study predicts a new topological effect resulting from the influence of extrinsic orbital angular momentum on spin angular momentum in converging asymmetrical light beams. It manifests as the transformation of linear polarized light into elliptically polarized light when an asymmetrical beam passes through the left or right half of the focal plane. The measured value of the topological circular amplitude anisotropy R was found to be R = +/- (0.60 +/- 0.08) x 10(-3). This new effect contributes to our understanding of light and has potential applications in developing sensors in optics.

Summary: Due to the complexity of resolving object form and pose in images, new vision algorithms prioritize identification and perception over accurate coordinate measurement. However, the use of planar targets for coordinate measurement in vision systems has several drawbacks, including calibration difficulties and limited viewing angles. On the other hand, the use of sphere targets is infrequent in vision-based coordinate metrology due to the lack of efficient multi-view vision algorithms for accurate sphere measurements.
