Summary: The role of CTAB cannot be ignored in the chiral synthesis of homochiral nanostructures, and the precise modulation of the Active Surface Growth is crucial for rational synthetic controls. By adjusting the ratio of ascorbic acid to Au precursor, the growth modes can be continuously changed, explaining the main trends of shape evolution and the inequivalent growth of the equivalent surfaces.

Summary: The behavior of adsorbed CTAB on Au(111) electrodes was studied using electrochemical and FTIR experiments in different aqueous solutions. The results showed that the adsorbed layer was stable in acidic solutions. Changes in electrode charge led to changes in electrode capacitance, resulting in characteristic peaks.

Summary: This study demonstrates the significance of CTAB in the synthesis of homochiral nanostructures. CTAB alone can induce Active Surface Growth and form nano-hexagrams with unique shapes. The growth rate and shape evolution can be controlled by modulating the ratio of ascorbic acid to Au precursor.

Summary: This study experimentally investigates the kinetics of radii in aqueous microbubble solutions and discusses the results in the context of Ostwald ripening. The obtained distributions of bubble radii are time-independent, and the growth and shrinkage speed of each bubble are governed by diffusion-limited Ostwald ripening. The cube of mean radius and mean volume exhibit a linear time evolution in agreement with the LSW theory.

Summary: A new ReaxFF force field has been developed to simulate the solvation and reactivity of metal carbonate systems in water. Molecular dynamics simulations were used to validate the force field and analyze the structure and dynamics of carbonate ions. The results are important for understanding the formation and dissolution of metal carbonates in solution.

Summary: The identification and control of the disintegration mechanism of polymer nanoparticles, particularly poly(N-isopropylacrylamide) (PNIPAM) mesoglobules, are crucial for their applications in transport and release systems. By inducing phase separation through fast pressure jumps, two disintegration mechanisms were observed: the release of single polymers from the surface of mesoglobules leading to size reduction, and the swelling of mesoglobules by water causing the chains to become more loosely associated.

Summary: This study investigated the chemical modification of fruit peels as novel bio-adsorbents for the removal of Zn(II) ions from water. Orange peels were found to be the most effective bio-adsorbents with a high adsorption capacity and removal efficiency. These results are significant for material selection in wastewater treatment technologies.

Summary: The sol-gel transition of aqueous pig-skin gelatin solutions at different concentrations and temperatures was investigated, with a focus on isothermal gelation kinetics. The dependence of gel time on concentration and temperature was evaluated, along with the different temperature dependence of the sol-gel transition according to the concentration regime. A full empirical model accommodating the dependence on both temperature and concentration was proposed.

Summary: Solid-contact ion-selective electrodes with thin membranes can achieve complete ion exchange and unbiased selectivity coefficients. The reconditioning rate corresponds well to experimental data. Alternatively, the redox state of the conducting polymer can be electrochemically switched to expel primary ions and uptake interfering ions.

Summary: This study describes a new technology for preparing fluorescent nanoprobe-based FL hydrogels. The use of hyperbranched polymers (HB) in combination with aggregation-induced emission (AIE) fluorogens significantly enhances the brightness and stability of the nanoprobe. The proposed method offers a one-step approach to prepare AIE-HB nanoprobe with excellent FL characteristics.

Summary: This study examines the single crystal structures of two bulky phosphonium compounds and investigates their self-assembly behavior. It is found that the organic cations form stable stacked columns with voids occupied by anions or solvent molecules. The analysis suggests that hydrogen bonding plays a dominant role in stabilizing the self-assembly.
