Electrooxidation treatment of simulated wastewater using mixed-metal oxide anodes for bacterial decontamination by Chandra, Poulomi, Choudhury, Diptiman, Verma, Anoop

“…The simulated wastewater comprising bacterial consortium was treated by employing mixed metal oxide (MMO). In particular, a lab-scale batch electrooxidation reactor was used at different operating parameters including NaCl dose ($n$), current density ($j$), and treatment time ($t$) in order to optimize the process using response surface methodology. …”

Photophysics of O-band and transition metal color centers in monolithic silicon for quantum communications by Murat Can Sarihan, Jiahui Huang, Jin Ho Kang, Cody Fan, Wei Liu, Khalifa M. Azizur-Rahman, Baolai Liang, Chee Wei Wong

“…This study explores and compares two promising O-band color centers in silicon for high-fidelity spin-photon interfaces: T and *Cu (transition metal) centers. During T center generation process, we observed the formation and dissolution of other color centers, including the copper-silver related centers with a doublet line around 1312 nm (* $${{{\rm{Cu}}}}_{n}^{0}$$ Cu n 0 ), near the optical fiber zero dispersion wavelength (around 1310 nm). …”

High-Field Growth of Semiconducting Anodic Oxide Films on Metal Surfaces for Photocatalytic Application by Ronald Vargas, David Carvajal, Brunella Galavis, Alberto Maimone, Lorean Madriz, Benjamín R. Scharifker

“…We discuss the scope and mechanisms for anodic oxide growth, describing the development of kinetic models and the correlations between theory and kinetic data, leading to fundamental information to characterize the primary processes occurring during the anodization of valve metals under high fields. The main features related to the widely used self-assembly of nanostructures by valve metal anodization are highlighted and briefly discussed. …”

Using Modified Fly Ash for Removal of Heavy Metal Ions from Aqueous Solution by Thuy Chinh Nguyen, Trang Do Mai Tran, Van Bay Dao, Quoc-Trung Vu, Trinh Duy Nguyen, Hoang Thai

“…The XRD patterns and FESEM images indicated that modified fly ash had zeolite structure with a pore size of about 50 nm. Heavy metal ion adsorption behavior as well as adsorption isotherm models (Langmuir and Freundlich) of Cd2+ and Hg2+ ions of the unmodified and modified fly ash were also investigated and discussed. …”
