Highly fluorescent CsPbBr3/TiO2 core/shell perovskite nanocrystals with excellent stability

SN Applied Sciences, 2021
The poor stability of CsPbX3 (X = Cl, Br, I) perovskite nanocrystals is the most impediment to its application in the field of photoelectrics. In this work, monodisperse CsPbBr3/TiO2 nanocrystals are successfully prepared by coating titanium precursor on

The Influence of Co-Precipitation Technique on the Structure, Morphology and Dual-Modal Proton Relaxivity of GdFeO₃ Nanoparticles

Inorganics, 2021
Nanocrystals of gadolinium orthoferrite (GdFeO3) with morphology close to isometric and superparamagnetic behavior were successfully synthesized using direct, reverse and microreactor co-precipitation of gadolinium and iron(III) hydroxides with their ...

Effect of Temperature and Capping Agents on Structural and Optical Properties of Tin Sulphide Nanocrystals

Journal of Nanotechnology, 2019
SnS nanocrystals were synthesized using bis(phenylpiperazine dithiocarbamate)tin(II) in oleic acid (OA) and octadecylamine (ODA) at three different temperatures (150, 190, and 230°C).

Direct synthesis of ultrasmall PbS nanocrystals passivated with a metal-halide-perovskite monolayer

, 2023
Inorganic shelling is a key strategy to address unwanted, surface-mediated non-radiative pathways in semiconductor nanocrystals. Improved passivation particularly advances the use of the smallest nanocrystals, because complex photophysics arise as ...

Study on the preparation of stabilizer-free silymarin nanocrystals and its oral absorption mechanisms

International Journal of Pharmaceutics: X
Many researchers have studied the oral absorption mechanisms yet, however, considering stabilizers often participate in the absorption process of nanocrystals, these known mechanisms may be incorrect.

Grain Refinement During Severe Plastic Deformation and Similitude of Subgrain Formation: A Molecular Dynamics Study

Advanced Engineering Materials, EarlyView.
Molecular dynamics is used to investigate structure refinement during severe plastic deformation. The results show similitude with experimental data. Molecular dynamics simulations of severe plastic deformation of monocrystalline and polycrystalline samples by multiaxial compression of aluminum are carried out.
