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 ...
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 ...
Linear dynamics modelling of droplet deformation in a pulsatile electric field
(
Institution of Chemical Engineers
, 2016 , Article)
A linear dynamic model of water droplet deformation in the presence of an electric field has been developed. Analytical solutions of the differential equation of motion are provided with different waveforms as forcing ...
Multi-layer multi-configuration time-dependent Hartree (ML-MCTDH) approach to the correlated exciton-vibrational dynamics in the FMO complex
(
American Institute of Physics Inc.
, 2016 , Article)
The coupled quantum dynamics of excitonic and vibrational degrees of freedom is investigated for high-dimensional models of the Fenna-Matthews-Olson complex. This includes a seven- and an eight-site model with 518 and 592 ...
Surface plasmon inhibited photo-luminescence activation in CdSe/ZnS core-shell quantum dots
(
Institute of Physics Publishing
, 2016 , Article)
In a composite film of Cdx Sey Zn1-x S1-y gradient core-shell quantum dots (QDs) and gold nanorods (NRs), the optical properties of the QDs are drastically affected by the plasmonic nanoparticles. We provide a careful study ...
Reaction Kinetics of Carbon Dioxide (CO2) with Diethylenetriamine and 1-Amino-2-propanol in Nonaqueous Solvents Using Stopped-Flow Technique
(
American Chemical Society
, 2016 , Article)
In this work, the reaction kinetics of carbon dioxide (CO2) with diethylenetriamine (DETA) and 1-amino-2-propanol (1-AP) in methanol and ethanol systems were measured using the stopped flow technique over a temperature ...
Kinetic and thermodynamic investigation of CO2 adsorption-desorption on polyethyleneimine - Mesoporous silica
(
TechConnect
, 2016 , Conference Paper)
Two CO2 solid sorbents based on polyethyleneimine, PEI (432 and 10k) impregnated into mesoporous silica (MPS) foam were synthesized and tested for CO2 capture. At ambient pressure, the amount of CO2 captured by these solid ...
