Journal Article
Physics and chemistry of photocatalytic titanium dioxide: visualization of bactericidal activity using atomic force microscopy
TL;DR: In this paper, an atomic force microscopy (AFM) technique was used to image the transformation of titanium surface to TiO 2 surface on anodization and observed wide distribution of TiO2 particles ranging from submicron to nanometre sizes, fully covering the substrate forming a thin film on anodicizing.
Journal ArticleDOI
Particle size dependence of magnetization and phase transition near TN in multiferroic BiFeO3
R. Mazumder,Saktiprosad Ghosh,Parthasarathi Mondal,Dipten Bhattacharya,Shouro Dasgupta,Nandini Das,Amarnath Sen,A.K. Tyagi,Manickam Sivakumar,Tsuyoshi Takami,Hiroshi Ikuta +10 more
TL;DR: In this article, a comprehensive study of the phase transition at the nanoscale was carried out, where electrical, thermal, and temperature dependent x-ray diffraction studies were employed to characterize the transition in a host of samples.
Journal ArticleDOI
Plasmon-mediated, highly enhanced photocatalytic degradation of industrial textile dyes using hybrid ZnO@Ag core–shell nanorods
TL;DR: Hybrid ZnO@Ag core-shell heterojunction nanorods were synthesized using a novel, facile two-step process based on hydrothermal and seed mediated growth techniques as discussed by the authors.
Journal ArticleDOI
TiO2 modification by gold (Au) for photocatalytic hydrogen (H2) production
TL;DR: In this paper, a brief description of TiO2-Au nanocomposite synthesis by different methods viz. sol-gel, photodeposition, deposition-precipitation simple reducing method and dispersion method is provided.
Journal ArticleDOI
Modifying the nanocrystalline characteristics: structure, size, and surface states of copper oxide thin films by high-energy heavy-ion irradiation
B. Balamurugan,Bodh Raj Mehta,D.K. Avasthi,Fouran Singh,Akhilesh K. Arora,M. Rajalakshmi,G. Raghavan,A.K. Tyagi,S. M. Shivaprasad +8 more
TL;DR: In this article, the effect of ion irradiation on nanocrystalline Cu2O thin films grown by the activated reactive evaporation technique was studied and the influence of dense electronic excitations on the structural and optical properties of the thin films was analyzed.
