Thermal Imaging of Nanostructures by Quantitative Optical Phase Analysis [PDF]

open access: yesACS Nano, 2012
We introduce an optical microscopy technique aimed at characterizing the heat generation arising from nanostructures, in a comprehensive and quantitative manner. Namely, the technique permits (i) mapping the temperature distribution around the source of heat, (ii) mapping the heat power density delivered by the source, and (iii) retrieving the absolute

Magnon BEC and various phases of 3D quantum helimagnets under high magnetic field [PDF]

open access: yes, 2009
We study high-field phase diagram and low-energy excitations of three-dimensional quantum helimagnets. Slightly below the saturation field, the emergence of magnetic order may be viewed as Bose-Einstein condensation (BEC) of magnons. The method of dilute

Adjustments to the preanalytical phase of quantitative cell-free DNA analysis

open access: yesData in Brief, 2016
Evaluating the kinetics of cell-free DNA (cfDNA) in the blood of cancer patients could be a strong auxiliary component to the molecular characterization of cfDNA, but its potential clinical significance is obscured by the absence of an analytical ...

Reaction Kinetics and Morphological Study of TiNb2O7 Synthesized by Solid-State Reaction

open access: yesArchives of Metallurgy and Materials, 2017
Although TiNb2O7 is regarded as a material with high application potential in lithium-ion batteries (LIBs) and solid-oxide fuel cells (SOFCs), it has been difficult to find suitable cost-effective conditions for synthesizing it on a commercial scale.
