A new and rapid method for preparing long-chain alkyltrimethylammonium salts with a variety of counterions
(1987)
A new, rapid, and simple method for preparing long-chain alkyltrimethylammonium (A1TA+X-) or long-chain alkylpyridinium (A1Py+X-) salts (X- = F-, Cl-, Br-, NO3-, SO42-, PO42-, car{ballot box}ylic anions, etc.) is presented. ...
Ab initio molecular dynamics simulations of Ti2 on C 20 collisions and C20Ti2 configurations
(2013)
The dynamics of the collision process of a titanium dimer against a C 20 nanocluster in the bowl configuration is simulated by means ab initio molecular dynamics, focusing our interest on the first steps to synthesize ...
Helical spin structure in iron chains with hybridized boundaries
(American Institute of Physics, 2020)
We have compared the magnetic properties of well-controlled ultra-short (<= 50nm) atomic iron (Fe) chains embedded in Fe-phthalocyanine films with those in Fe-hydrogen (H-2) phthalocyanine superlattices. Surprisingly, we ...
Unprecedented differences in the diamond nucleation density between carbon- and silicon-faces of 4H-silicon carbides
(Elsevier, 2020)
4H-silicon carbides deposited by diamond films have wide applications in many fields such as semiconductor heterojunction, heat sink and mechanical sealing. Nucleation plays a critical role in the deposition of the diamond ...
Spin-wave modes in ferromagnetic nanodisks, their excitation via alternating currents and fields, and auto-oscillations
(American Physical Society, 2017)
The excitation of the linear spin wave modes of a soft ferromagnetic free layer of a nanopillar structure through dc-ac currents that traverse the structure is studied, as well as with ac magnetic fields. There is interest ...
Wetting transitions displayed by persistent active particles
(American Physical Society, 2017)
A lattice model for active matter is studied numerically, showing that it displays wetting transitions between three distinctive phases when in contact with an impenetrable wall. The particles in the model move persistently, ...
Effect of the Dispersing Agent on the Electrochemical Response of Glassy Carbon Electrodes Modified with Dispersions of Carbon Nanotubes
(2012)
The electrochemical response of a glassy carbon electrode modified with carbon nanotubes (CNT) dispersed in two solvents, water and DMF, and two polymers, chitosan and Nafion is reported. The films were homogeneous when ...
Study of the variational patterns for corrosion kinetics of carbon steel as a function of dissolved oxygen and NaCl concentration
(Elsevier Ltd, 2009)
The simultaneous occurrences of electrochemical reactions responsible for corrosion of carbon steel in NaCl solutions have been analyzed on the basis of the mixed potential theory in order to determine the combined effect ...
Zone i of Tear Microdesiccates Is a Lipid-Containing Structure
(Lippincott Williams and Wilkins, 2017)
Copyright © 2016 Wolters Kluwer Health, Inc. All rights reserved. Purpose: Morphological features of tear microdesiccates on glass surfaces have been associated with tear fluid status. Tear-film lipids play a critical role ...
Low-energy ion beam synthesis of ag endotaxial nanostructures in silicon
(Springer, 2018-06)
Coherently, embedded metal nanostructures (endotaxial) are known to have potential applications concerning the areas of plasmonics, optoelectronics and thermoelectronics. Incorporating appropriate concentrations of metal ...
