High Excitation Intensity Opens a New Trapping Channel in Organic-Inorganic Hybrid Perovskite Nanoparticles
(
American Chemical Society
, 2016 , Article)
We investigated the excited-state dynamics of CH3NH3PbBr3 perovskite nanoparticles (NPs) and bulk crystals under various excitation intensity regimes using transient absorption spectroscopy. We confirmed the sub-band gap ...
Catalytic evaluation of nickel nanoparticles in methane steam reforming
(
Elsevier
, 2016 , Article)
Development of a highly efficient and coke-resistant, nickel nanoparticles (Ni.NPs) based catalyst in the steam reformation reaction of methane is reported. The catalyst was prepared by dispersing Ni-nanoparticles over ...
Reaction kinetics of carbon dioxide with aqueous solutions of l-Arginine, Glycine & Sarcosine using the stopped flow technique
(
Elsevier
, 2017 , Article)
The use of amino acids as potential solvents for carbon dioxide (CO2) capture has been considered by a number of researchers. However, very little is known about the kinetics and mechanism of amino acids-CO2 reactions. In ...
Effect of the support on physicochemical properties and catalytic performance of cobalt based nano-catalysts in Fischer-Tropsch reaction
(
Elsevier Ltd
, 2017 , Article)
In this paper, comparative investigations of the effects of CNTs and ?-Al2O3 on the physicochemical properties and catalytic performances of Co based nano-catalyst during FTS have been presented. Catalysts were prepared ...
Reprint of “The effect of site-specific spectral densities on the high-dimensional exciton-vibrational dynamics in the FMO complex”
(
Elsevier B.V.
, 2018 , Article)
© 2017 Elsevier B.V. The coupled exciton-vibrational dynamics of a three-site model of the FMO complex is investigated using the Multi-layer Multi-configuration Time-dependent Hartree (ML-MCTDH) approach. Emphasis is put ...
Multilayer-MCTDH approach to the energy transfer dynamics in the LH2 antenna complex
(
Institute of Physics Publishing
, 2017 , Article)
The multilayer multiconfiguration time-dependent Hartree method is used to study the coupled exciton–vibrational dynamics in a high-dimensional nonameric model of the LH2 antenna complex of purple bacteria. The exciton–vibrational ...
Direct Experimental Evidence for Photoinduced Strong-Coupling Polarons in Organolead Halide Perovskite Nanoparticles
(
American Chemical Society
, 2016 , Article)
Echoing the roaring success of their bulk counterparts, nano-objects built from organolead halide perovskites (OLHP) present bright prospects for surpassing the performances of their conventional organic and inorganic ...
Flocculation and viscoelastic behavior of industrial papermaking suspensions
(
Springer New York LLC
, 2016 , Article)
The effects of the surface charge type and density C496, C492 and A130LMW polyacrylamides (PAMs) on the rheological behavior of real industrial papermaking suspensions were quantitatively related to the degree of flocculation ...
Trap States and Their Dynamics in Organometal Halide Perovskite Nanoparticles and Bulk Crystals
(
American Chemical Society
, 2016 , Article)
Organometal halide perovskites have attracted tremendous attention for optoelectronic applications. Charge carrier trapping is one of the dominant processes often deteriorating the performance of devices. Here, we investigate ...
Controlled growth of Cu2O thin films by electrodeposition approach
(
Elsevier Ltd
, 2017 , Article)
Thin films of Cu2O comprised of wavelike surface characteristic of compact nanoparticles were synthesized using a facile and cost-effective electrodeposition approach. The distinct surface morphologies with well-aligned ...
