Summary: This study focuses on identifying the critical conditions for obtaining a high-performance superhydrophobic surface on a TiO2 substrate. The study found that using ethanol as the solvent, a temperature of 40 degrees C, and a stearic acid concentration of 600 ppm with an immersion time of 100 minutes resulted in a superhydrophobic surface with a contact angle of 151.38 degrees. Additionally, a concentration of 1000 ppm and an immersion time of 120 minutes resulted in a contact angle of 162.06 degrees, indicating high superhydrophobicity.

Summary: Two different positional isomers of carbonate-terminated alkanethiol molecules were synthesized and used to create self-assembled monolayers (SAMs) on gold as mimics of commercially available polycarbonate surfaces. The characterization of the adsorbate molecules and SAMs was done using various spectroscopic techniques. The wettabilities of both SAMs were found to be similar to that of poly(ethylene carbonate) samples, indicating that the carbonate-terminated SAMs can be used to study the interfacial properties of polycarbonates without interference from surface reconstruction.

Summary: ETL-free perovskite solar cells (PSCs) have potential for commercialization due to their simple design and fabrication. However, the interface between indium doped tin oxide (ITO) and perovskite is not optimal. Surface modification of ITO using self-assembled monolayers (SAMs) has shown improvement in device performance, but stability is often overlooked. This study introduces naphthalene-imide SAMs and examines their impact on the thermal stability of triple-cation PSCs, finding that they improve stability and power output.

Summary: Due to their size, conventional high performance liquid chromatographs (HPLCs) are difficult to place close to a reaction vessel within a pharmaceutical manufacturing or development site. However, a compact and modular separation system using capillary HPLC has been developed to enable co-location of an HPLC with a small-scale reactor for reaction monitoring. The compact system showed equivalent quantitative performance to an Agilent 1290 Infinity II HPLC system.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.

Summary: A chitosan-alginate sponge with multiple cross-linking networks was developed for adsorption and enrichment of anionic dyes from food samples. The sponge showed better three-dimensional network structure, mechanical behavior, and stability compared to pure chitosan and alginate sponges. The adsorption performance and selectivity of the sponge were systematically studied, and it maintained high adsorption capacity and selectivity for anionic dyes. The sponge also showed satisfactory reusability and was successfully combined with high-performance liquid chromatography for the enrichment and detection of anionic dyes in candy and cocktail samples.
