Excited State Calculations of Cu-Doped Anatase TiO2 (101) and (001) Nanofilms
Lin, Yin-Pai; Neilande, Elina; Bandarenka, Hanna; Zavatski, Siarhei; Isakoviča, Inta; Piskunov, Sergei; Bocharov, Dmitri; Kotomin, Eugene A. (MDPI, 2024)Excited state calculations are performed to predict the electronic structure and optical absorption characteristics of Cu-doped anatase TiO2 nanofilms, focusing on their (101) and (001) surface terminations. Using model ... -
Improvement of Heat Dissipation in Ag/Ni Substrates for Testing Cu-TiO2/TiO2-Modified Filters Using SERS Spectroscopy
Bandarenka, Hanna; Burko, Aliaksandr; Girel, Kseniya; Laputsko, Diana; Orel, Elizaveta; Mizgailo, Anna; Sharopov, Utkirjon; Podelinska, Alise; Shapel, Uladzislau; Pankratov, Vladimir; Piskunov, Sergei; Bocharov, Dmitry (MDPI, 2023)Surface-enhanced Raman scattering (SERS) spectroscopy is used to investigate a composition of wash swabs from the Cu-TiO2/TiO2-modified filters with disinfecting ability. Macroporous Si chips coated with conformal 800 nm ... -
Ultraviolet Exposure Improves SERS Activity of Graphene-Coated Ag/ZrO2 Substrates
Bandarenka, Hanna; Burko, Aliaksandr; Laputsko, Diana; Dronina, Lizaveta; Kovalchuk, Nikolai; Podelinska, Alise; Shapel, Uladzislau; Popov, Anatoli I.; Bocharov, Dmitry (MDPI, 2023)This study reveals a significant improvement in surface-enhanced Raman scattering (SERS) activity of Ag/ZrO2 substrates covered with a few-layer graphene preliminary exposed to ultraviolet (UV) light. The SERS-active ...
