Myristic acid

Lauric acid (12:0, Nacalai Tesque, Kyoto, Japan), myristic acid (Wako Pure Chemicals), palmitic acid (16:0, Wako Pure Chemicals) and oleic acid (18:1, Nacalai Tesque) were dissolved in DMSO. To generate bovine serum albumin‐bound fatty acids, each fatty acid was mixed with an equal volume of phosphate‐buffered saline containing 10% (w/v) fatty acid‐free bovine serum albumin (Wako Pure Chemicals). After sonication, the mixture was added to cell culture medium (0.5% v/v final concentration of DMSO), and the cells were further incubated for 24–48 h. The cultured cells were harvested for western blot analysis.

The organic monocarboxylic acids sodium salts; n-capric acid (CH₃(CH₂)₈COOH), myristic acid (CH₃(CH₂)₁₂COOH), and stearic acid (CH₃(CH₂)₁₆COOH) were obtained from WAKO Company (Tokyo, Japan). The supplies of dicarboxylic acids sodium salts (suberic acid COOH(CH₂)₆COOH and sebacic acid COOH(CH₂)₈COOH) were from TCI Company (Tokyo, Japan). The nanohybrids were formed through anions exchange reactions. Typically, the appropriate concentration of organic acid (0.2 M) was prepared through dissolving 0.002 mol of the sodium salt of aliphatic acids in 10 mL of deionized–distilled water. By using ultrasonic technique, this aqueous solution of organic acid was mixed with 0.5 g of the prepared Co/Zn/Ti LDH for performing intercalation reactions. This process was achieved under an argon atmosphere with strong stirring at room temperature for 24 h. The product was filtrated and washed many times by deionized–distilled water. The fine powder was obtained after drying under vacuum.
