The band gap energy of the materials was investigated using UV–vis diffuse reflectance spectroscopy (DRS) (Shimadzu, UV-2600). X-ray photoelectron spectroscopy (XPS) was performed on Kratos Analytical ...

Including invariance of global properties of a phys-ical system as an intrinsic feature in graph neural networks (GNNs) enhances the model's robustness and generalizability and reduces the amount of ...

The basics: Most of the sun's rays are visible light – the colors we can see. But some are invisible ultraviolet (UV) rays, which can damage our skin.
