Summary: The study focuses on a multi-component approach to materials design for energy-conversion-oriented applications. It investigates a 5-component multimetallic chalcogenide compound with a pentlandite structure, which shows promise in electrocatalytic water splitting. The solubility limit of an additive, selenium, in a trimetallic Co3Fe3Ni3S8 system is determined, and the effects of consolidation conditions on the material's morphology and properties are discussed. By tailoring both the chemical composition and processing conditions, efficient electrocatalysts for water splitting can be optimized.

Summary: By incorporating Fe as a dopant in TiO2 nanoparticles, oxygen vacancies and dopant energy levels can be generated, promoting the adsorption and activation of N2 molecules. Surface modification with F induces Fe (III) in a high spin state and upshifts the dopant energy level, facilitating Fe 3d electrons backdonation to N 1ag* orbital to promote N2 molecule activation and reduce the limiting potential of NRR. The F-Fe: TiO2 electrocatalyst achieved the highest Faradaic efficiency and maximum NH3 production rate, providing insights into designing catalyst surface electronic states for efficient N2 to NH3 conversion.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.
