Nanotube TiO2 with diameter of ~50 nm was identified for Ti3, while Ti7 displayed sheet-like structure.
Then, the research shifts to hollow structured nanotubes that will provide larger surface area.
The 7-times coatings resulted in the formation of sheet-like structure TiO2 after HCl dissolution (ZnO etching).
VOC is solar cell parameter which is mostly influenced by the photoanode structure.
Seven-times dip-coating produced sheet-like structure, while the three-times generated nanotube structure.

Structure and properties of recycled aromatic thermoplastic polyester nanocomposites R.Merijs Meri1, a, J.Zicans1, b, T.Ivanova1, b, R.Berzina1, b, G.Japins1, b, J.Locs2 1 Institute of Polymer Materials, Riga Technical University, Azenes street 14/24, Riga, LV 1048, Latvia 2Riga Biomaterial Innovation and Development Center, Riga Technical University, Pulka street 3/3, Riga, LV 1007, Latvia aremo.merijs-meri@rtu.lv (corresponding author), bzicans@ktf.rtu.lv Keywords: polymer nanocomposite, recycling, structure, mechanical properties Abstract.
Structure as well as mechanical and thermal properties of the nanocomposites based on recycled polyethylene terephthalate (RPET) are investigated. 1, 2 and 5 wt. % of unmodified montmorillonite nanoclay (MMT) were introduced in the RPET matrix by melt compounding in a twin screw extruder.
In the current research structure and properties of the nanocomposites based on recycled poly(ethylene terephthalate) and modified with neat montmorillonite clays are investigated.
Main reason for increased thermal stability of the RPET nanocomposite most probably is due to the limited access of oxygen to the burning zone and consequently changed combustion chemistry.

The structures of the synthesized polymers were characterized by UV-Vis Spectroscopy, FT-IR, and 1H-NMR.
After that, the crystal structure of CaCO3 scale from the scale inhibition test was examined using a scanning electron microscope.
The first stage at low temperatures (40–300 °C) is assigned to the evaporation of extraction solvent or entrapped moisture in the polymer structure.

A variety of technical means were used to characterize the structure and photochemical properties of the catalysts.
Anatase crystal structure of Fe3+ undoped composite photocatalyst was better.
That may be the Fe3+ in TiO2 doping was introduced into the internal structure, leading to the formation of lattice defects.
