Uniform and highly ordered nanocrystalline multilayers were obtained after tetrahydrofuran annealing of pre-assembled nanocrystals on the substrate surfaces. As a result of the rearrangement process during solvent annealing, cerium oxide hybrid na...
Two types of silver nanoparticle (Ag NP)dye nano-composite layers were prepared on an indium-tin oxide (ITO) transparent electrode, where porphyrins were fixed on the Ag NPs by chemical bonding through their carboxylate moieties or by hydrophobic ...

Hafnium oxide nanoparticles were synthesized via a short-duration (10 min) hydrothermal reaction. The reaction was found to produce three differently shaped nanoparticles: flower-like nanostructures (20 nm diameter), polycrystalline nanoagglomerat...
Photocurrent generation efficiency via the photoactive dyes, porphyrins, was strongly enhanced by construction of a nanocomposite structure, which consists of an undercoat layer of (3-mercaptopropyl)trimethoxysilane and densely and homogeneously a...

Sufficiently dense films of cerium oxide nanocrystals modified with decanoic acid, with sizes of ∼9 nm, were fabricated on the surface by modifying a silicon substrate with 3,4-dihydroxyhydrocinnamic acid, where catechol group lied at the top. By ...
Silica nanoparticles with sizes of 210 and 440 nm were grafted with (P)- or (M)-1, 12-dimethylbenzo[c]phenanthrenes by silane coupling with helicenamidated (3-aminopropyl)trimethoxysilane. The chiral nanoparticles deaggregated and aggregated with ...

A new copper(II) complex with a (bdpg-His) ligand was prepared and its structural properties were investigated both in crystalline and in solution states; (bdpg-His) = N,N-bis(2-pyridylmethyl)carnosine methylester. In the solid state, the complex ...
Hydrophobic aniino acid, L-phenylalanine, formed insoluble aggregates with unique morphologies at hydrothermal condition. The analyses by infrared spectrum and gel permeation chromatography indicate the highly efficient synthesis of cyclic dipheny...
