摘要:
A synthetic gel for crystal growth, which induces only secondary growth from the surface of a silicalite-1 or zeolite beta seed crystal and cannot induce crystal nucleation in the synthetic gel for crystal growth or on the surface of the seed crystal. The synthetic gel contains fumed silica, tetraethylammonium hydroxide (TEAOH), [(NH4)2SiF6], KOH, and H2O, or contains tetraethylorthosilicate (TEOS), tetraethylammonium hydroxide (TEAOH), hydrogen fluoride, and H2O.

Provided is method of preparing a printed matter with a printed array of particles, the method including: (a) preparing a template, a surface of which has depressions or projections capable of fixing the positions and/or orientations of one or more particles; (b) placing the particles on the template and applying a physical pressure to the particles so that a portion or the whole of each particle is inserted in each of pores defined by the depressions or the projections to form a particle array; and (c) contacting the template having thereon the particle array to a printing substrate so that the particle array is transferred to the printing substrate. Provided is also a method of preparing a printed matter with a printed array of particles, the method including: (a) preparing a template, at least a surface portion of which has adhesive property; (b) placing particles on the template and applying a physical pressure to the particles so that the particles are immobilized on adhesive surface portions of the substrate to form a particle array; and (c) contacting the template having thereon the particle array to a printing substrate so that the particle array is transferred to the printing substrate.
