Chiral ceramic nanoparticles and peptide catalysis
(American Chemical Society, 2017)The chirality of nanoparticles (NPs) and their assemblies has been investigated predominantly for noble metals and II-VI semiconductors. However, ceramic NPs represent the majority of nanoscale materials in nature. The ... -
Electrospun Fe2O3 entrenched SiO2 supported N and S dual incorporated TiO2 nanofibers derived from mixed polymeric template/surfactant: enriched mesoporosity within nanofibers, effective charge separation, and visible light photocatalysis activity
(American Chemical Society, 2019)The α-Fe2O3 promoted and SiO2 supported N and S dual incorporated TiO2 nanofibers (FeSiNST NFs) along with neat oxide NFs have been synthesized by electrospinning via sol–gel. The keen approach is that mixed polyvinylpyrrolidone ... -
Elucidating the barriers on direct water splitting: key role of oxygen vacancy density and coordination over PbTiO3 and TiO2
(American Chemical Society, 2021-01-28)In this work, using the state-of-the-art first-principles calculations based on density functional theory, we found that the concentration and coordination of surface oxygen vacancies with respect to each other were critical ... -
Graphene nanoreactors : photoreduction of prussian blue in aqueous solution
(American Chemical Society, 2017)Prussian dyes are characterized by interesting photomagnetic properties due to the photoinduced electron transfer involved in the Fe oxidation and spin state changes. Ferromagnetic Prussian blue (PB) in contact with titanium ... -
MIMIM photodetectors using plasmonically enhanced MIM absorbers
(SPIE, 2017)We demonstrate super absorbing metal-insulator-metal (MIM) stacks and MIMIM photosensitive devices operating at visible and near-infrared (VIS-NIR) spectrum, where absorbing (top) MIM and photocollecting (bottom) MIM can ... -
Multispectral plasmonic structures using native aluminum oxide and aluminum
(OSA, 2017)We report the use of native aluminum oxide to fabricate periodic metal-insulator-metal resonators with simultaneous resonances in the visible and IR wavelengths. The cavity size is in the order of λ3/25000 in the NIR. -
Nonlinear laser lithography for indefinitely large-area nanostructuring with femtosecond pulses
(Nature publishing group, 2013)Dynamical systems based on the interplay of nonlinear feedback mechanisms are ubiquitous in nature. Well-understood examples from photonics include mode locking and a broad class of fractal optics, including self-similarity. ... -
Photocatalytic conversion of nitric oxide on titanium dioxide: cryotrapping of reaction products for online monitoring by mass spectrometry
(American Chemical Society, 2016)Details of coupling a catalytic reaction chamber to a liquid nitrogen-cooled cryofocuser/triple quadrupole mass spectrometer for online monitoring of nitric oxide (NO) photocatalytic reaction products are presented. Cryogenic ... -
The substrate temperature dependent electrical properties of titanium dioxide thin films
(2010)Titanium dioxide thin films were obtained by a dc sputtering technique onto heated glass substrates. The relationship between the substrate temperature and the electrical properties of the films was investigated. Electrical ... -
Tailoring insoluble nanobelts into soluble anti-UV nanopotpourris
(Royal Society of Chemistry, 2011)Soluble, transparent and anti-UV nanopotpourris have been prepared by tailoring long nanobelts. The strains and layered structures facilitate the breaking of the as-synthesized nanobelts under an applied mechanical action. ... -
The tight-binding approach to the corundum-structure d compounds
(Institute of Physics Publishing Ltd., 1994)The analysis of electronic structures has been carried out for the transition-metal compounds showing the corundum-type crystal symmetry using the suggested tight-binding method for interacting bands. With the self-consistent ... -
Toxicity of lanthanum oxide (La2O3) nanoparticles in aquatic environments
(Royal Society of Chemistry, 2015)This study demonstrates the acute toxicity of lanthanum oxide nanoparticles (La2O3 NP) on two sentinel aquatic species, fresh-water microalgae Chlorella sp. and the crustacean Daphnia magna. The morphology, size and charge ... -
Visible photoluminescence from SiOx films grown by low temperature plasma enhanced chemical vapor deposition
(Pergamon Press, 1995)a-SiOx films of varying stoichiometry have been prepared by low temperature plasma enhanced chemical vapor deposition. The majority of films showed photoluminescence (PL) and films prepared in a narrow range of gas flows ...
