Summary: This work explores an eco-friendly approach to extracting cashew nut shell liquid (CNSL) and refining cardanol from cashew nuts produced in Hainan, China. CNS, which is usually considered waste from agricultural processing, can be extracted into valuable CNSL using solvent extraction or supercritical CO2 extraction. The composition of extracted CNSL varies with different conditions, and less polar solvents extract more CNSL. Supercritical CO2 extraction also shows superior performance in CNSL extraction as an environmentally friendly method. CNSL from Hainan cashew nuts contains a high amount of anacardic acid. The extracted CNSL can be decarboxylated and separated to obtain a mixture of cardanol consisting of four olefins with different numbers of double bonds. Cardanol can be converted to saturated cardanol and high purity cardanol monoene through catalytic hydrogenation and catalytic transfer hydrogenation, respectively. Both saturated cardanol and cardanol monoene have promising prospects due to their chemical structure.

Summary: Cardanol, the main component of CNSL, was hydrogenated and converted to Bis-CNSL using aldehydes in the presence of an acid catalyst without a solvent. High selectivity for Bis-CNSL was achieved using aldehydes with alkyl chains of 2 or more carbons. A large-scale preparation process using propionaldehyde with reduced aldehyde amount and recrystallization from methanol resulted in Bis-CNSL purity over 99%.

Summary: The thermodynamic and electrochemical properties of Ag+ ions in ChCl and G mixture were investigated, and MD and DFT methods were used for computational simulation. The specific mass, speed of sound, viscosity, and refractive index of the solution were measured at different temperatures. The electrochemical behavior of Ag+ ions was analyzed by cyclic voltammetry, and silver coatings were successfully electrodeposited on the Au surface. SEM analysis revealed the surface morphologies of the electrodeposits. The computational calculation showed that adding silver nitrate to the eutectic solvent had a predominant repulsive effect and negligible influence on sound velocity and refractive index. MD simulations demonstrated a strong interaction between Ag+ ions and Cl ions.

Summary: The mechanical properties and corrosion resistance of annealed superferritic stainless steel model alloy 25Cr-6Mo-5Ni were studied in 0.6 M NaCl solution. The microstructure exhibited a ferrite matrix and eutectoid phase with a lamellar structure distributed at grain boundaries and within the ferrite grains with a spherical morphology. The model alloy displayed brittle behavior according to tensile and impact results. Fractography analysis revealed the presence of cleavage facets, river patterns, and micro-cracks at grain boundaries and across the ferrite grains. Pitting corrosion initiated within the eutectoid phase containing chrome depletion zones. Electrochemical impedance spectroscopy measurements indicated that the breakdown of passive films was more susceptible in the eutectoid phase.
