Summary: Aqueous sodium-ion batteries based on Prussian Blue Analogues (PBA) have the potential to be scalable energy storage systems. This study investigates the degradation processes in PBA electrodes during charge-discharge cycles. It finds that the dissolution of nickel and cobalt is the main cause of degradation, and the nature of the anions in the electrolyte affects the degradation rate, with perchlorate being the most unstable and sulfate the most stable. The study proposes that the dissolution process is initiated by the adsorption of anions during electrode oxidation.

Summary: Two extremophilic biosorbents were used to successfully remove Cu(II), Ni(II), and Pb(II) from aqueous solutions. The biosorbents showed high affinity for these metal ions, with removal rates ranging from 73.6% to 100%, and the removal order was Pb(II) > Cu(II) > Ni(II). Both Langmuir and Freundlich models were suitable for describing the adsorption process, with the pseudo-second-order reaction model being more accurate than the pseudo-first-order model kinetically.

Summary: In this study, a novel magnetic potassium cobalt hexacyanoferrate composite (MKCoFC) was synthesized, which had excellent adsorption properties for Rb+ and allowed rapid separation from the liquid phase by outside magnetic force. The adsorption capacity of MKCoFC towards Rb+ was explored and found to be consistent with the Langmuir model. MKCoFC displayed promising selectivity, with high adsorption for Rb+ and hardly any adsorption for other ions in coexisting solution. Furthermore, MKCoFC showed good regenerability and maintained high adsorption efficiency after multiple cycles.

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.
