Zinc uptake from ZnSO4 (aq) and Zn-EDTA (aq) and its root-to-shoot transport in soybean plants (Glycine max) probed by time-resolved in vivo X-ray spectroscopy
(2020-03-01)
This study investigated the dynamic of zinc (Zn) uptake and the root-to-shoot Zn-transport when supplied as ZnSO4 (aq) or Zn-EDTA (aq) in soybean seedlings using in vivo X-ray fluorescence (XRF) and X-ray absorption ...
Surface modification of ZnO quantum dots by organosilanes and oleic acid with enhanced luminescence for potential biological application
(2017-01-01)
Luminescent ZnO-QDs is a promising candidate for biological application, especially due to their low toxicity. Nevertheless, colloidal ZnO-QDs prepared by sol-gel route are unstable in water and incompatible with lipophilic ...
Violet ZnSe/ZnS as an Alternative to Green CdSe/ZnS in Nanocrystal-Fluorescent Protein FRET Systems
(AMER CHEMICAL SOC, 2009)
Fluorescent proteins from the green fluorescent protein family strongly interact with CdSe/ZnS and ZnSe/ZnS nanocrystals at neutral pH. Green emitting CdSe/ZnS nanocrystals and red emitting fluorescent protein dTomato ...
Magnetic and highly luminescent heterostructures of gd3+/zno conjugated to gcis/zns quantum dots for multimodal imaging
(2021-07-01)
In recent years, the use of quantum dots (Qdots) to obtain biological images has attracted attention due to their excellent luminescent properties and the possibility of their association with contrast agents for magnetic ...
Electrochemical behavior of Sn-Zn alloys with different grain structures in chloride-containing solutions
(Elsevier, 2017-01-03)
In the present research the electrochemical behavior of the Sn-Zn alloys (Sn-1 wt.%Zn, Sn-4 wt.%Zn and 8.9 wt.%Zn) in 3% NaCl solution is analyzed using potentiodynamic cyclic polarization measurements and Electrochemical ...
The shell effect on the room temperature photoluminescence from ZnO/MgO core/shell nanowires: Exciton-phonon coupling and strain
(Institute of Physics Publishing, 2017)
© 2017 IOP Publishing Ltd.The room temperature photoluminescence from ZnO/MgO core/shell nanowires (NWs) grown by a simple two-step vapor transport method was studied for various MgO shell widths (w). Two distinct effects ...
NIR luminescence from erbium doped (100-x)SiO2:xZnO powders obtained by soft chemical synthesis
(2016-02-01)
We present the structural and optical results of (100-x)SiO2:xZnO compounds with x=0, 20, 40, 60, 80, and 100, containing 1 mol% of Er3+ prepared by a simple chemical route. It was evaluated the crystallization effect on ...
Effect of the addition of ZnO seeds on the electrical proprieties of ZnO-based varistors
(Elsevier B.V., 2003-05-26)
ZnO has the characteristic of presenting an intermediate value for the effective 3 eV barrier at room temperature. ZnO ceramics are applied in high-voltage systems or circuits. Attempts were made to reduce the number of ...
Increased antibacterial activity of ZnO nanoparticles: Influence of size and surface modification
(2019-05-01)
In the current study, the size and surface of ZnO nanoparticle (ZnO NP) suspensions and powders were finely controlled to evaluate their influence on the ZnO antibacterial activity against Staphylococcus aureus and Escherichia ...
High-performance ultraviolet-visible driven ZnO morphologies photocatalyst obtained by microwave-assisted hydrothermal method
(2018-02-15)
The use of extensive, time-consuming synthesis and the cost of an additional element in synthesis makes difficult the synthesis of photocatalyst active under a broad wavelength range. We propose a synthesis method to obtain ...
