This study was conducted in the period of 2012 to 2015 in some locations of Japan. At each location, samplings were carried out on reef slopes using SCUBA diving, on reef flats, tidal beaches and river mouths during low tide. The specimens then were treated using a differential interference contrast microscope with a camera lucida (BX-50, OLYMPUS), a quick auto-coater (JFC-1500, Ion Sputtering Device), a scanning electron microscope (SEM) in the laboratory of Shizuoka University.

Nano-hydroxyapatite/starch composite was synthesized using in situ precipitation. Starch concentration effect on the structure of composite was examined. Characterization of the obtained samples, The X-ray diffraction and Fourier transform infrared spectroscopy demonstrated the purity of the formed nano-HA in the starch matrix. Morphology studies of the samples, checked by field emission scanning electron microscope and transmission electron microscope, show the effects of starch on the size, shape, and morphology of hydroxyapatite nanoparticles.

In this work, we replaced the conventional solvents such as dimethyl sulfoxide (DMSO) or dimethylformamide (DMF) by deep eutectic solvents (DES) in the synthesis of methylammonium lead iodide perovskite (MAPbI3). The first DES system was based on the combination of acetamide and urea (A–U–P system), the homogenous solution was formed at relative low temperature (~40℃). For the second system which was based on acetamide and choline chloride (A–C–P system), lead nitrate only dissolved at higher temperature (~100℃).
