In Situ Raman Monitoring of the Formation and Growth of Carbon Nanotubes via Chemical Vapor Deposition
An in situ measurement technique based on Raman spectroscopy is established to simultaneously monitor the parameters of interest of the solid and gas phases during the formation and growth of carbon nanotubes (CNT) in a cold wall reactor for catalytic chemical vapor deposition (CCVD). Iron nanoparticles were used as a…

Study of molecular interactions and dynamics in LDPE–silica nanocomposites using FTIR spectroscopy.
Some Effect of Chemical Treatment by Ferric Nitrate Salts on the Structure and Morphology of Coir Fibre Composites
The present study shows some important effects of chemical treatment on the structure and morphology of coir fibre. The objective of the present study is to optimise overall properties of coir fibre so as to use coir fibre as a reinforcing agent in thermoplastic and thermosetting polymers. In the present study, coir f…
A density functional theory study on 3d metal/graphene for the removal of CO from H 2 feed gas in hydrogen fuel cells
In M/graphene (M = Sc–Cu) systems, Fe, Co and Ni show higher efficiency for the removal of CO from H 2 feed gas.
3-Substituted 6-oxoverdazyl bent-core nematic radicals: synthesis and characterization
Bent-core mesogens containing the 6-oxoverdazyl as the central angular unit exhibit rare nematic behavior.
Synthesis, Characterization and Evaluation of the Cytotoxicity of Ni‐Doped Zn(Se,S) Quantum Dots
Quantum dots (QDs) are semiconductor nanocrystals with desirable optical properties for biological applications, such as bioimaging and drug delivery. However, the potential toxicity of these nanostructures in biological systems limits their application. The present work is focused on the synthesis, characterization,…

Fast optimization of mesoporous ternary metal oxide (CuCeZrO(w)) catalysts for n-hexane oxidation is achieved via a newly developed combinatorial approach based on ink-jet printing assisted synthesis and multi-dimensional group testing.
Rapid crystal growth of type-II clathrates A 8 Na 16 Si 136 (A = K, Rb, Cs) by spark plasma sintering
Single crystals of clathrate-II A 8 Na 16 Si 136 (A = K, Rb, Cs) were synthesized by spark plasma sintering by simultaneous electrochemical redox and ion-exchange reactions.
SIMMER-III Analyses of Local Fuel-Coolant Interactions in a Simulated Molten Fuel Pool: Effect of Coolant Quantity
Studies on local fuel-coolant interactions (FCI) in a molten pool are important for the analyses of severe accidents that could occur for sodium-cooled fast reactors (SFRs). To clarify the mechanisms underlying this interaction, in recent years, several experimental tests, with comparatively larger difference in coola…
Hemoglobin-mediated synthesis of PEDOT:PSS: enhancing conductivity through biological oxidants
Hemoglobin- and catalase-polymerized PEDOT: PSS were characterized by X-ray photoelectron spectroscopy, visible and near-IR spectroscopy, FTIR, and ESR. Hemoglobin-polymerized PEDOT: PSS possesses bipolarons, while catalase-polymerized PEDOT: PSS is dominated by polarons. Use of heme-bound iron as an oxidant yields PE…
Cu vacancies modulated the room temperature ferromagnetism in Cu 2 O/Cu nanoparticle composites
The Cu2O/Cu nanoparticle composites have been fabricated by heating a mixture of copper nitrate and different amounts of glycine. Magnetic measurement results indicate that the Cu2O/Cu composites show clear ferromagnetism, while the pure Cu2O and Cu show diamagnetism only. Through analyzing the photoluminescence X-ray…
The reactivity of stoichiometric tungsten oxide clusters towards carbon monoxide: the effects of cluster sizes and charge states
Density functional theory (DFT) calculations are employed to investigate the reactivity of tungsten oxide clusters towards carbon monoxide. Extensive structural searches show that all the ground-state structures of (WO3)n(+) (n = 1-4) contain an oxygen radical center with a lengthened W-O bond which is highly active i…
Modeling tensorial conductivity of particle suspension networks
Significant microstructural anisotropy is known to develop during shearing flow of attractive particle suspensions. These suspensions, and their capacity to form conductive networks, play a key role in flow-battery technology, among other applications. Herein, we present and test an analytical model for the tensorial…
