    Hydrophobic cryogels with monolithic supermacropores based on poly-trimethylolpropane trimethacrylate (pTrim) containing 1-(2-Hydroxyl-5-nonyphenyl)ethanone oxime (LIX84-I) were successfully prepared by a cryo-polymerization technique using organic solvents with freezing points between room temperature and around 0 °C as solvents. The prepared cryogels were characterized in terms of macroscopic shape and porous structure. The cryogels had a monolithic supermacroporous structure and high contents of LIX84-I depending on the added amount of the extractant to the monomer solution. The amount of LIX84-I impregnated in the cryogel had a linear relationship with the added amount of LIX84-I in the monomer solution for cryo-polymerization. Cu(II) in the aqueous solution was immediately adsorbed into the cryogel containing LIX84-I.

    We report a novel method for the synthesis of silver nanowires (AgNWs). In this method, silver chloride (AgCl) and N,N-dimethyl-dodecylamine hydrochloride (C12H25NMe2·HCl) are used as a silver source and a protecting agent, respectively. Heating of both reagents in N,N-dimethyldodecylamine forms silver chlorocomplex, AgCl1‒nn solving homogeneously in the melting C12H25NMe2·HCl. The addition of the reducing agent, N,N-dibenzylhydroxyamine to the reaction mixture in order to reduce AgCl1‒nn to silver atom (Ag0) gives firstly multiplied twinned nanoparticles (MTPs), and then uniform silver nanowires (AgNWs) with the dimension of 50‒100 nm in thickness and >20 µm in length. Thermogravimetric analysis of the product reveals that highly pure AgNWs containing less organic residues are obtained. We investigate the effects of loading ratios of tertiary amine hydrochlorides to AgCl, the molecular structures of amines, and reaction temperature on the morphologies and yields of the generated AgNWs. We demonstrate that the MTPs are efficiently generated by the reduction reaction of AgCl1‒nn in the presence of tertiary amine hydrochlorides, and that tertiary amine hydrochlorides also play an important role in anisotropic crystal growth of Ag0 to AgNWs through the formation of the MTPs.

    Crosslinked-gel microcapsules immobilized small droplets of phenolic oxime extractant, 1-(2-hydroxy-5-nonylphenyl) ethanone oxime (LIX84-I) were prepared from O/W emulsion using falling-drop method followed by crosslinking of sodium alginate (Na-Alg) by Ca2+ ion and crosslinking of polyvinyl alcohol (PVA) by glutaraldehyde. A lot of fine droplets of LIX84-I were successfully immobilized in the microcapsules. The LIX84-I contents in the microcapsules increased with an increase in the LIX84-I amounts to the aqueous phase. The maximum extracted amounts of Cu(II) increased linearly with the LIX84-I contents with a slope of 1/2 which means two molecules of LIX84-I react with one Cu(II) ion. The extraction rate was not significantly affected by the size of the extractant droplets dispersed in the microcapsules. The microcapsules could be used repeatedly for the extraction and back-extraction of Cu(II).

    In order to apply microcapsules as a functional material of cement composites, such as self-healing and heat-transfer-controlling materials, the effect of the addition of microcapsules on the mechanical properties of cement mortar was investigated. Polystyrene microcapsules containing CaCl2 aqueous solution as a microencapsulation substance with monocore and multicore structures were successfully prepared from solid-in-oil-in-water (S/O/W) emulsion by the solvent evaporation method. The compressive strengths of the mortars with and without the microcapsules were measured at various curing times. The compressive strength of the mortar without microcapsules increased with curing time. The compressive strength of the mortar with the microcapsules was lower than that without microcapsules and increased with time. The decrease in the compressive strength increased with the amount of the microcapsules added in the mortar. The self-healing effect of cracked mortar by CaCl2, which would be supplied from the microcapsules due to outer mechanical force making cracks in the mortar and on the microcapsules was not clearly shown in this experiment. However, permeation and leakage of Cl- ion to the surrounding mortar from the microcapsules was observed by mapping analysis of SEM-EDX.

    Here, we prepared hydrophobic cryogel particles with monolithic supermacropores based on poly-trimethylolpropane trimethacrylate (pTrim) by combining the inverse Leidenfrost effect and cryo-polymerization technique. The hydrophobic cryogel particles prepared by adopting this method demonstrated the separation of the stabilized O/W emulsion with surfactant. The prepared cryogel particles were characterized in terms of macroscopic shape and porous structure. It was found that the cryogel particles had a narrow size distribution and a monolithic supermacroporous structure. The hydrophobicity of the cryogel particles was confirmed by placing aqueous and organic droplets on the particles. Where the organic droplet was immediately adsorbed into the particles, the aqueous droplet remained on the surface of the particle due to repelling force. In addition, after it adsorbed the organic droplet the particle was observed, and the organic solvent was diffused into the entire particle. It was indicated that monolithic pores were distributed from the surface to the interior. Regarding the application of the hydrophobic cryogel particles, we demonstrated the separation of a stabilized oil-in-water emulsion, resulting in the successful removal of the organic solvent from the emulsion.
