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 ...
Effect of Zn and Ni substitution on structural, morphological and magnetic properties of tin oxide nanoparticles
(
Elsevier
, 2016 , Article)
Structural, morphological, optical and magnetic properties of Zn and Zn–Ni co-doped tin oxide (SnO2) nanoparticles synthesized by sol-gel method. The influence of doping concentration on phase and particle size of the ...
Functionalization of zinc oxide (ZnO) nanoparticles and its effects on polysulfone-ZnO membranes
(
Taylor and Francis Inc.
, 2016 , Article)
Incorporation of nanoparticles in membranes has recently been reported to lead to enhancement of the membrane performance for various applications. In this study, ZnO nanoparticles were synthesized via sol-gel method using ...
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 ...
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 ...
Electroactive and Optically Adaptive Bionanocomposite for Reconfigurable Microlens
(
American Chemical Society
, 2016 , Article)
This paper introduces an electroactive bionanocomposite based on poly(diethylene glycol adipate) (PDEGA) and cellulose nanocrystals (CNCs). The bionanocomposites were made using CNCs extracted from cotton and by optimizing ...
A versatile in situ etching-growth strategy for synthesis of yolk–shell structured periodic mesoporous organosilica nanocomposites
(
Royal Society of Chemistry
, 2016 , Article)
This paper describes a versatile in situ etching-growth strategy for the preparation of periodic mesoporous organosilica (PMO) composites with yolk-shell structure, which can generate the void space and construct the outer ...
Soft-shear induced phase-separated nanoparticle string-structures in polymer thin films
(
Royal Society of Chemistry
, 2016 , Article)
Application of shear stress has been shown to unidirectionally orient the microstructures of block copolymers and polymer blends. In the present work, we study the phase separation of a novel nanoparticle (NP)-polymer blend ...
Selective H2S sensor based on CuO nanoparticles embedded in organic membranes
(
Elsevier B.V.
, 2016 , Article)
We report on H2S gas sensors based on CuO nanoparticles that are embedded within polymer membranes of poly-vinyl-alcohol (PVA) and glycerol ionic liquid (IL). The nanoparticles were fabricated by the colloid microwave ...
Heat transfer enhancement of nanofluids using iron nanoparticles decorated carbon nanotubes
(
Elsevier Ltd
, 2016 , Article)
Enhancing heat transfer in thermal fluid systems can contribute significantly towards the improvement of thermal efficiency resulting in reducing energy consumption and hence carbon emission. Conventional fluids like water ...
