To facilitate on-site detection by nonspecialists, there is a demand for the development of portable "sample-to-answer" devices capable of executing all procedures in an automated or easy-to-operate manner. Here, we developed an automated detection device that integrated a magnetofluidic manipulation system and a signal acquisition system. Both systems were controllable via a smartphone.

Context: This study aims to reveal the reaction mechanisms of H and O on the NiO(100) and Ce-doped NiO(100) surfaces using the density functional theory (DFT) combined with the on-site Coulomb correction (DFT + U) method. It was found that H and O react favorably on the reduced surfaces of both materials. However, after the oxygen vacancy is filled, the activation energy for the reaction between H₂ and lattice oxygen increases.

Matrix-assisted laser Desorption/Ionization Mass Spectrometry Imaging (MALDI MSI) is an analytical technique used for the spatial mapping of drugs, explosives, and organic samples, making it a game-changer in Forensic examination. It detects a wide range of biomolecules in their native state without specific tags, antibodies, labels, and dyes. This review aims to highlight the advancement of MALDI-MSI over time and its impact on Forensic Science due to high-resolution molecular imaging.
