Summary: This paper proposes a modified testing method using barium nitrate to determine the chloride ion concentration of concrete in marine environment. It investigates the influences of sulphate ions and allied cations on the accuracy of chloride ion concentration measurement. The results show that barium nitrate is suitable for determining total chloride ion concentration, while traditional water-soluble method is more accurate for free chloride ion concentration measurement.

Summary: Based on the structure and function of natural ClC selectivity filter, a ClC-type single channel molecule with high ion transport activity and excellent Cl-/K+ selectivity was designed. It exhibited a permeability ratio of P Cl /PKthorn up to 12.31, comparable to natural ClC proteins, and showed high anion/anion selectivity and pH-dependent conductance and ion selectivity. The ClC-like transport behavior was achieved through hydrogen bonding, anion-pi interactions, and pH-responsive terminal phenylalanine residues in the central macrocyclic skeleton.

Summary: Artificial biomimetic chloride anionophores have potential applications in anticancer scaffolds. Stimuli-responsive chloride transporters that can be selectively activated inside cancer cells are rare. Light-responsive systems, with their spatiotemporal controllability, low toxicity, and high tunability, show promise for photodynamic therapy. In this work, o-nitrobenzyl-linked, benzimidazole-based protransporters and active transporters were studied, and one compound showed efficient ion transport activity. Detailed mechanistic studies revealed the main ion transport process and the necessity of double protection with photocages for complete activation by external light. The activated procarriers induced phototoxic cell death in MCF-7 cancer cells.

Summary: Artificial biomimetic chloride anionophores have potential applications as anticancer scaffolds. Stimuli-responsive chloride transporters that can be selectively activated inside cancer cells are rare, and light-responsive systems show promise for photodynamic therapy. In this study, O-nitrobenzyl-linked, benzimidazole-based protransporters and benzimidazole-2-amine-based active transporters were synthesized. Trifluoromethyl-based anionophore showed efficient ion transport activity, and mechanistic studies revealed Cl-/NO3- antiport as the main ion transport process. Activation of the protransporters inside MCF-7 cancer cells induced phototoxic cell death.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: The study shows that the as-fabricated mortar has a better corrosion resistance rate of 98.60% increase against chloride salt attack compared to the reference sample. The AgNO3 color development experiment and free chloride ion concentration measurements reveal that the as-fabricated mortar can adsorb chloride ions inside and effectively inhibit the penetration of external chloride ions. This internally and externally coordinated anti-corrosion cement mortar is expected to prolong the service life of reinforced concrete in chloride salt environments.

Summary: When aluminium-rich phase minerals are added to Portland cement, a substitution reaction occurs, forming a hydrated silica-calcium aluminate (C-A-S-H), which changes the cement material's molecular structure. This study used simulation to investigate how the Al substitution reaction affects the adsorption of chloride and sulphate ions. The results showed that the C-A-S-H structure generated by the Al substitution reaction increased the physical adsorption capacity of the chloride and sulphate ions.

Summary: The preparation of columns using electrostatic attachment of anion exchange latex particles with charge density gradients can enhance chromatographic performance at low linear velocity. Significant improvement in chromatographic performance is observed during gradient elution chromatography when multiple successive charge density gradients are prepared along the length of the column with the highest capacity oriented at the inlet end of the column.

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: We developed a CRISPR-empowered electrochemical biosensor, named PER-E-CRISPR, for amplification-free and sensitive detection of miR-21. The biosensor combines the advantages of CRISPR/Cas13a and primer exchange reaction (PER) for target amplification. Under optimized conditions, the PER-E-CRISPR assay exhibits a linear range from 10-13 to 10-7 M and a limit of detection of 30.2 fM. The biosensor shows excellent performance in actual plasma, indicating promising prospects for miRNA detection in molecular diagnosis.

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.
