Hierarchy in 1D carbon nanostructures: from theoretical design and properties calculation to experimental synthesis and characterization.
(2008)"A key challenge in nanotechnology is the assembly of nanostructured components (building blocks; such as DNA molecules, 0D clusters and 1D nanowires) into well ordered arrays. Based on this research trend, the core proposal ... -
High temperature martensitic transformation and giant magnetocaloric effect in Ni40Co10Mn41Sn9 melt-spun ribbons
(Elsevier, 2018)"We report a large magnetic entropy change associated with a high-temperature martensitic transformation in Ni40Co10Mn41Sn9 (at. %) melt-spun ribbons. The ribbons underwent a first-order forward martensitic transition and ... -
High-gain nonlinear observer for simple genetic regulation process
(Elsevier, 2007)"High-gain nonlinear observers occur in the nonlinear automatic control theory and are in standard usage in chemical engineering processes. We apply such a type of analysis in the context of a very simple one-gene reg-ulation ... -
High-magnetic field characterization of magnetocaloric effect in FeZrB(Cu) amorphous ribbons
(2015-05)"The magnetic and magnetocaloric properties of a series of Fe-rich FeZrB(Cu) amorphous ribbons were investigated under magnetic field values up to mu H-0 of 8 T. A correlation between the saturation magnetization and the ... -
High-pressure characterization of multifunctional CrVO4
(IOP Publishing, 2020)"The structural stability and physical properties of CrVO(4)under compression were studied by x-ray diffraction, Raman spectroscopy, optical absorption, resistivity measurements, andab initiocalculations up to 10 GPa. ... -
High-pressure synthesis of β-Ir4B5 and determination of the compressibility of various iridium borides
(American Chemical Society, 2018)"A new iridium boride, beta-Ir4B5, was synthesized under high-pressure/high-temperature conditions of 10.5 GPa and 1500 degrees C in a multianvil press with a Walker-type module. The new modification beta-Ir4B5 crystallizes ... -
High-quality InN films on MgO (100) substrates: the key role of 30 degrees in-plane rotation
(2014-05)"High crystalline layers of InN were grown on MgO(100) substrates by gas source molecular beam epitaxy. Good quality films were obtained by means of an in-plane rotation process induced by the annealing of an InN buffer ... -
Highly efficient production of nitrogen-doped multiwalled carbon nanotubes using banded iron formation from the Bundelkhand craton located in the north of India
