Summary: Controlling the stability of oil-in-water emulsions is a key focus for scientists studying colloidal systems. Carbon dots have gained significant interest as smart materials due to their exceptional physicochemical properties and versatile applications. This study presents advanced and switchable O/W emulsions stabilized by the combined effect of the cationic surfactant CTAB and similarly charged CDs. The formulated emulsion shows universal stabilizing effects for a range of oil phases and can be switched between stable and unstable modes by adding anionic surfactant SDBS, with potential applications in water purification, pharmaceuticals, protein recognition, and catalysis.

Summary: Bioavailability refers to the fraction of a substance that is absorbed from the gastrointestinal tract and enters the bloodstream. This study aimed to assess the bioavailability of selenium (Se) from dietary supplements and explore the influence of diet type on relative bioavailability. The research used a two-stage in vitro digestion model to simulate the digestion of food containing dietary supplements. Selenium bioavailability ranged from 19.31% to 66.10% in the presence of food matrix. Sodium selenate had the highest bioavailability, followed by organic forms and sodium selenite. The basic diet with moderate protein and high carbohydrate and fiber content positively influenced Se bioavailability. The pharmaceutical form of the product also affected bioavailability, with tablets having the highest bioavailability, followed by capsules and coated tablets.

Summary: Adsorption materials based on Aspergillus niger spores were chemically modified with CTAB to enhance the biosorption capacity of chromic acid ions. The secondary amine (-NH-) played a crucial role in the reduction adsorption process, reducing hexavalent chromium by transferring electrons to unoccupied orbit of Cr(VI). The fungal biological adsorbent showed promising potential for repeated adsorption and desorption of hexavalent chromium without significant decrease.

Summary: The emergence of superconductivity and a charge density wave phase in air-stable organic cation intercalated MoS2 crystals is reported. The properties of the correlated electronic phases are shown to depend dramatically on the intercalated cation, demonstrating the potential of organic ion intercalation to finely tune the properties of 2D materials. Organic-ion intercalated MoS2 is established as a platform to study the emergence and modulation of correlated electronic phases.

Summary: The study investigates the effect of using DDAA and CTAB as a mixed collector on the flotation separation of diaspore and kaolinite. The experimental results show that the use of DDAA and CTAB significantly improves the flotation separation performance of diaspore and kaolinite. The adsorption analysis and molecular dynamics simulation support the experimental findings, showing that the interaction energies between DDAA and diaspore are more negative, while the interaction energies between CTAB and kaolinite are also more negative. The theoretical calculations and experimental results indicate that the enlarged difference in adsorption amounts is beneficial for the flotation separation performance of minerals.

Summary: This study investigated the competitive sorption of Se(IV) and Se(VI) on different types of schwertmannite at varying initial Se concentrations and mixing ratios. It was found that at lower adsorbate concentrations, an inner-sphere corner-sharing bidentate binuclear complex forms upon exchange with sulphate, while at higher concentrations, both oxyanions become bound to SHM through mainly inner-sphere and partly outer-sphere corner-sharing bidentate binuclear complexes.

Summary: This study investigates the potential of Pleurotus ostreatus and Pleurotus djamor mushrooms to absorb and accumulate selenium in organic substrate. The results show that Pleurotus djamor grown on Se(IV)-supplemented substrate has the greatest potential for selenium uptake and accumulation. Various selenium species, including selenomethionine, selenocystine, and Se-methylselenocysteine, were identified in the mushrooms. In vitro digestion assays showed high bioaccessibility of selenium. The bioaccessible selenium species were found to be mainly associated with low molecular weight proteins in the mushrooms.

Summary: A method using GC-MS/MS was developed to simultaneously determine cyanide and thiocyanate in milk. Derivatization of cyanide and thiocyanate with PFB-CN and PFB-SCN was achieved with Pentafluorobenzyl bromide (PFBBr). CTAB was used as a phase transfer catalyst and protein precipitant, enabling the separation of organic and aqueous phases and simplifying the pretreatment procedures. The method showed low LODs (0.006 mg/kg and 0.015 mg/kg) and good spiked recoveries (90.1% to 98.2% and 91.8% to 98.9%) with low RSDs (less than 18.9% and 15.2%) for cyanide and thiocyanate in milk, making it a simple, fast, and highly sensitive method.

Summary: The thermodynamic properties of the cationic surfactant CTAB/water system were investigated, establishing a stable phase diagram and a metastable phase diagram. The transitions of the micellar and LC phases into a metastable gel phase were observed. Additionally, a two-step transition from the CTAB crystal + solution to the micellar and LC phases was found, with the enthalpy of fusion of coexisting ice not indicating hydration of the CTAB crystal by non-freezing water.

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.

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.
