Grain size-dependent magnetic and electric properties in nanosized YMnO3 multiferroic ceramicsNanoscale Research Letters - Tập 6 Số 1
T. C. Han, Wei‐Yen Hsu, Wei-Da Lee
AbstractMagnetic and electric properties are investigated for the nanosized YMnO3 samples with different grain sizes (25 nm to 200 nm) synthesized by a modified Pechini method. It shows that magnetic and electric properties are strongly dependent on the grain size. The magnetic characterization indicates that with increasing grain size, the ant...... hiện toàn bộ
Study of nanostructure growth with nanoscale apex induced by femtosecond laser irradiation at megahertz repetition rateNanoscale Research Letters - Tập 8 Số 1 - Trang 1-12 - 2013
Patel, Nikunj B, Tan, Bo, Venkatakrishnan, Krishnan
Leaf-like nanostructures with nanoscale apex are induced on dielectric target surfaces by high-repetition-rate femtosecond laser irradiation in ambient conditions. We have recently developed this unique technique to grow leaf-like nanostructures with such interesting geometry without the use of any catalyst. It was found to be possible only in the presence of background nitrogen gas flow. In this ...... hiện toàn bộ
Facile Synthesis of Monodisperse CdS Nanocrystals via MicroreactionNanoscale Research Letters - Tập 5 - Trang 130-137 - 2009

CdS-based nanocrystals (NCs) have attracted extensive interest due to their potential application as key luminescent materials for blue and white LEDs. In this research, the continuous synthesis of monodisperse CdS NCs was demonstrated utilizing a capillary microreactor. The enhanced heat and mass transfer in the microreactor was useful to reduce the reaction temperature and residence time to synt...... hiện toàn bộ
Altering the Optical Properties of GaAsSb-Capped InAs Quantum Dots by Means of InAlAs InterlayersNanoscale Research Letters - Tập 14 - Trang 1-6 - 2019

In this work, we investigate the optical properties of InAs quantum dots (QDs) capped with composite In0.15Al0.85As/GaAs0.85Sb0.15 strain-reducing layers (SRLs) by means of high-resolution X-ray diffraction (HRXRD) and photoluminescence (PL) spectroscopy at 77 K. Thin In0.15Al0.85As layers with thickness t = 20 Å, 40 Å, and 60 Å were inserted between the QDs and a 60-Å-thick GaAs0.85Sb0.15 layer. ...... hiện toàn bộ
Effects of the electrical excitation signal parameters on the geometry of an argon-based non-thermal atmospheric pressure plasma jetNanoscale Research Letters - Tập 9 - Trang 1-5 - 2014

A non-thermal atmospheric pressure argon plasma jet for medical applications has been generated using a high-voltage pulse generator and a homemade dielectric barrier discharge (DBD) reactor with a cylindrical configuration. A plasma jet of about 6 cm of length has been created in argon gas at atmospheric pressure with an applied peak to peak voltage and a frequency of 10 kV and 50 kHz, respective...... hiện toàn bộ
Self-assembly of copper and cobalt complexes with hierarchical size and catalytic properties for hydroxylation of phenolNanoscale Research Letters - Tập 6 - Trang 1-7 - 2011

A feasible and effective self-assembly method to synthesize different scale coordination polymers in highly dilute solution (from nanocrystals to microcrystals and to bulk crystals) without any blocking agent has been described. The growth of crystalline particles was controlled by removing the particles at different reaction times to interrupt the growth at the desired size. The nano and microsca...... hiện toàn bộ
