Ebook "From single molecules to nanoscopically structured materials" principle relied on the defined functionalization of macromolecules and macromolecular assemblies. The basic idea was to chemically encode the building blocks, permitting better control of structure formation. The placement of ionic or hydrogen-bonding groups into well-defined positions, the definition of amphiphilic “patches” and the creation of directed as well as non-directed interactions have led to novel aggregate topologies in solution as well as on surfaces.

In this study, a new copolymer, which is a combination of two chemical structure (9,10-di(furan-2-yl)anthracene and 3,4-ethylenedioxythiophene was synthesized via electrochemical synthesis methods in the electrolyte medium of 0.1 M TBAPF6 / ACN solution. PEDOT homopolymer was also electrosynthesized for comparator experiments of the polymer formations in the same medium. The characterizations of polymers were achieved with general optical and electrochemical characterization techniques.

D-arabinitol is a sugar alcohol that is a typical metabolite of Candida species. The hydroxy group owned by D-arabinitol can function as a reducing agent that can reduce Ag+ to AgNPs. The resulting colloid is further stabilized by the addition of a capping agent. The capping agent used in this study was a combination of chitosan 1%(w/w) and PEG 6000 1% (w/w) (2:1) v/v. The formation of AgNPs causes an increase in the surface plasmon resonance spectra of the colloid solution at a wavelength of 430 nm with a slight blue shift.

Phase formation upon hydrothermal crystallization of sodium titanosilicates has been studied in detail. It was shown that an excessive amount of Na and Si with respect to Ti affects the crystallization. It demonstrates that in a clear starting solution, high crystalline microporous titanosilicate (CST, Na2Ti2SiO7⋅2H2O) with sitinakite structure can be formed in 6 h and the crystallization is controlled by nucleation
