“…Generally, inorganic nanomaterials with dimensions from 1-100 nm can be classified into different categories based on their geometric shape such as spherical (e.g., metal and metal oxide nanoparticles) [11], fibril-shaped (e.g., carbon nanotubes and metal wires) [12], and platelet-like (e.g., natural smectite clays, graphite, and graphene sheets) [1][2][3][4][5][6][7][8][9][10]13]. The miniaturization of materials to nanometer size often leads to increase the surface area-to-volume ratios and surface energies, consequently producing unique physical properties.…”

“…Ether and polyether amines are valuable synthetic compounds with applications in diverse areas such as surface chemistry, colloid chemistry, and bioconjugate chemistry (Bayat and Akarsu, 2002;Hedberg, 1970;Mongondry et al, 2003). Polyether amines may be used as curing agents, silica deposition agents, in paintings, or as intermediates in the synthesis of polyamides or polyureas (Brandl et al, 2010;Harris et al, 1984;Lin et al, 2010). Ether amines can be produced chemically by a reaction of haloalkyl ethers with ammonia or diamines at high pH and high temperature (Buckmann et al, 1981), or by the cyanoethylation of ether alcohols with acrylonitrile followed by hydrogenation of the corresponding cyanoethers (Froimowicz et al, 2005).…”

We constructed an enzymatic network composed of three different enzymes for the synthesis of valuable ether amines. The enzymatic reactions are interconnected to catalyze the oxidation and subsequent transamination of the substrate and to provide cofactor recycling. This allows production of the desired ether amines from the corresponding ether alcohols with inorganic ammonium as the only additional substrate. To examine conversion, individual and overall reaction equilibria were established. Using these data, it was found that the experimentally observed conversions of up to 60% observed for reactions containing 10 mM alcohol and up to 280 mM ammonia corresponded well to predicted conversions. The results indicate that efficient amination can be driven by high concentrations of ammonia and may require improving enzyme robustness for scale-up. Biotechnol.

Fatty-amine modified silicate clays of layered structure were prepared by conventional intercalation of noctadecyl amine (n-C 18 H 37 NH 2 , ODA) into sodium montmorillonite clay (Na + -MMT). Organically modified clays are considered as a new type of phase change materials (PCM). At one equivalent ratio of ODA-HCl over Na + -MMT by an ionic exchange reaction, the interlayer galleries of the silicates' layered structure were expanded from 12Å to 28Å as measured by X-ray diffraction (XRD) analysis. As a result, the organoclay (ODA/MMT) became hydrophobic and spacing was accessible for incorporating a second organic compound, n-octadecane. Physical absorption of n-octadecane in ODA/MMT allowed interlayer spacing and further expansion from 28Å to 30Å. Absorption efficiency, defined as the weight of noctadecane over ODA/MMT, ranged from 5.3 to 9.1 fold depending on the amount of ODA intercalation.Since n-octadecane is a kind of paraffin wax, a phase change temperature of 25-29 C was observed.The n-octadecane was characterized by thermal gravimetric analysis (TGA) to study absorption efficiency of ODA/MMT. During the heating process, the ODA/MMT/n-octadecane powder remained in solid state without any liquid leakage at 80 C (far beyond the phase change temperature). Thus, the organoclay (ODA/MMT) can be used as good thermal storage and phase change material.
