Summary: Sulfur-impregnated zeolite was successfully obtained by chemical modification of natural zeolite clinoptilolite with Na2S, which enhanced the sorption of Hg(II) from aqueous solutions. The impregnation increased basicity and negative surface charge, decreased specific surface area and crystallinity, and showed optimal sorption capacity under acidic conditions.

Summary: The CO2 adsorption performances of Linde-Type A (LTA) and natural Clinoptilolite (Clino) zeolites were investigated and compared. The ion-exchange procedure enhanced the adsorption capacity of the synthetic zeolite, while no significant improvement was observed for the natural one. Both synthetic and natural zeolites were affected by the cation exchange process in terms of CO2 adsorption reversibility. Natural Clino showed interesting CO2 adsorption performances at medium-high temperature and proved the presence of Fe2+ ions responsible for its strong interaction with CO2. The low cost and availability in shaped form make natural Clino a promising material for real CCS technologies.

Summary: This study investigates the ability of natural clinoptilolite zeolite as a low-cost adsorbent for removing heavy metal ions, specifically lead, cadmium, and cobalt, from the aquifer. The results indicate that the adsorption capacity of clinoptilolite increases with an increasing initial concentration of elements in the solution, with a higher capacity for removing lead and cadmium. The Langmuir model provides a better fit with the adsorption data.

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.

Summary: Molecular docking (MD) analysis is widely used for studying the interaction between aptamers and small molecules. This study established steady-state aptamers of tertiary structures (SATS) using specific aptamers of tetracycline antibiotics as docking models. Molecular docking results revealed multiple binding sites in the SATS of aptamers, with significant variations in binding free energy (BFE) and docking score (DS). The study also proposed a method for MD analysis based on SATS, providing insights into binding mode and predicting binding sites.
