Research output: Contribution to conferencePaperpeer-review


We applied the core-shell particle with the volume of atto liter scale to a reactor for producing nano-sized materials. Particles were allowed to array on the substrate with the spin-coater or the LB apparatus. The target solution was added to the particle-arrayed substrate, and then the surplus was removed before drying. The obtained materials had unique forms such as a cubic and a fiber. The form of the NaCl crystals was a nano-sized cubic, whereas urea exhibited a needle-like shape. Crystals of urea appeared to make the connection between nano-particles. The form of the CaCO3 crystals was a nano-size cubic and the size was dependent on a CaCl2 concentration and a reaction time. In conclusion, this crystallization method was easier and more economical than conventional ones.
