Summary: This study investigated the effects of side chain structures on the glass transition temperature and water interactions in cellulose esters. The results showed that the glass transition temperature decreased with increased side chain length, and the solubility and penetration of water in the cellulose esters decreased as well.

Summary: In this study, an all-polymer optical fiber sensor for dissolved oxygen sensing using phase-fluorometry was presented. The research demonstrated the use of Hansen Solubility Parameters to formulate a solvent mixture with good solubility of polymer matrix and luminophores simultaneously. This approach can be extended to other polymers and luminophores, making it a valuable tool for researchers in photoluminescence and polymeric matrices.

Summary: Equilibrium solubilities of evodiamine were determined in various aqueous mixtures using the shake-flask method, with the dependence on temperature and mixture composition described by different models. The solubility behavior of evodiamine is influenced by factors such as solvent cavity term and dipolarity-polarizability.Selective solvation of evodiamine by different solvents in the mixtures was observed based on the results. Thermodynamic quantities and transfer properties were also calculated and discussed.

Summary: This study aims to find a low-cost, flexible thermoelectric generator using eco-friendly metal oxide-based materials for low-temperature applications. The study reveals that the performance of the flexible thermoelectric generator can be improved by fine-tuning the materials' properties such as crystallite size, bandgap, carrier concentration, carrier mobility, resistivity, the Seebeck coefficient, and micro-porosity of the ink film.

Summary: The intercalation of carbon nanotubes (CNTs) interlayer has been proven effective in improving membrane performance in water treatment, but its effectiveness in organic solvent separation has not been studied yet. In this study, a polyketone (PK)based CNTs-interlayered thin-film composite (TFC) polyamide (PA) membrane was developed and applied in organic solvent reverse osmosis (OSRO) process, resulting in a threefold increase in membrane permeance with a rejection rate of 99.2%. Furthermore, analysis based on Hansen solubility parameters (HSP) theory revealed the influence of selective layer and different solvent mixtures on rejection. This work provides valuable insights for the design of high-performance OSRO membranes and understanding of solvent separation mechanisms.

Summary: The study investigated the equilibrium solubility, solvation performance, and dissolution thermodynamics of etonogestrel in various binary aqueous blends with different cosolvents. Results showed that the solubility of etonogestrel was influenced by solvent-solvent and solute-solvent interactions, leading to different solubility parameters in each solution.

Summary: The choice of stabilizers for preventing particle agglomeration during nanomilling is a complex process. This study shows how the selection of polymeric stabilizers can be narrowed down based on Hansen solubility parameters, and the importance of solubility parameter difference in achieving colloidal stability.

Summary: Cellulose is a sustainable and abundant biopolymer that can be used in developing fibre-reinforced polymeric composites. Inverse gas chromatography (IGC) is a successful technique for characterising the surface activity of cellulose-based fillers and predicting the behaviour of final products.

Summary: A novel composite gel polymer electrolyte (GPE) matrix composed of highly thermo-stable polyimide and eco-friendly cellulose acetate propionate (CAP) nanofibers was successfully fabricated. The PI-CAP GPE exhibited ultra-flexibility, high mechanical strength, excellent thermal stability, high ionic conductivity, and Li+ transference number. It showed good cyclic stability and rate capability in lithium metal batteries, making it a promising cellulose-based quasi-solid electrolyte.

Summary: This study focused on the solubility of systems formed by 4-(bromomethyl)-2(1H)-quinolinone (BMQ) and blended solvents with water, using shake-flask equilibration method. The research found satisfactory correlation results and conclusions using modified models, as well as insights into the relative contributions to solubility variations. The preferential solvation of BMQ in different solvent blends was quantitatively analyzed, revealing solvent properties responsible for solubility changes.

Summary: 3D printing enables sustainable product innovations through novel design, reduced use of materials, and local manufacturing. This research studied the properties of a cellulose-based composite in injection molding and 3D printing processes. The results showed that the polymer matrix could be directly recyclable for both processes without degradation, while microcellulose was more sensitive to thermal stress. The mechanical and thermal properties of the cellulose-based composites remained close to initial levels throughout the multiple processing cycles.

Summary: Various co-solvents and surfactants were tested for the washing of oil sludges, with cyclohexane found to be a more environmentally friendly alternative to toluene. The use of surfactants such as rhamnolipid, Triton X-100, and Triton X-114 can significantly improve oil recovery rates, with the surfactant concentration having minimal impact on the process.
