This article reports a comparative study of bulk and surface properties in the transition metal dichalcogenide 1T−TaS2. When heating the sample, the surface displays an intermediate insulating phase that persists for ∼10 K on top of a metallic bulk. The weaker screening of Coulomb repulsion and a stiffer charge density wave (CDW) explain such resil...
X-ray Absorption Spectroscopy (XAS) is a widely used diagnostic method for studying electronic and structural properties of matter. At first glance, the relatively narrow bandwidth highly fluctuating spectral structure Free Electron Lasers (XFEL) sources seem to require accumulation over many shots achieve high data quality. To date best approach i...
Although structures of vitrified supramolecular complexes have been determined at near-atomic resolution, elucidating in situ molecular structure in living cells remains a challenge. Here, we report a straightforward liquid cell technique, originally developed for real-time visualization of dynamics at a liquid-gas interface using transmission elec...
The H2020 SafeSpace project aims at the implementation of a space weather safety prototype, in particular to predict the deep charging hazard. The proposed service is built on a Sun‐to‐Earth chain of physical codes that propagates physical information and uncertainties in order to model the outer radiation belt dynamics. In this paper, we present t...
This research work brings out a novel equation for photo electric effect, which doesn't involve the mass and velocity of the electron emitted due to the incident photon, rather it involves the frequency of motion of the ejected electron, which is under motion.
Here, we study the upper critical solution temperature triggered phase transition of thermally responsive poly(ethylene glycol)-block-poly(ethylene glycol) methyl ether acrylate-co-poly(ethylene glycol) phenyl ether acrylate-block-polystyrene nanoassemblies in isopropanol. To gain mechanistic insight into the organic solution-phase dynamics of the ...
Several lines of evidence suggest that a characteristic of the neuropathology of Alzheimer's disease (AD) is the aggregation of the amyloid beta peptides (Aβ), fragments of the human amyloid precursor protein (hAPP). The dominating species are the Aβ40 and Aβ42 fragments with 40 and 42 amino acids, respectively. Aβ initially forms soluble oligomers...
Mitochondria are critical to the governance of metabolism and bioenergetics in cancer cells1. The mitochondria form highly organized networks, in which their outer and inner membrane structures define their bioenergetic capacity2,3. However, in vivo studies delineating the relationship between the structural organization of mitochondrial networks a...
The objective of this work is to study the feasibility of developing a stochastic specification model of the radiation environment near Earth, taking into account both the short-term dynamics (a few weeks) and the long-term dynamics (solar cycle). Extending from a previous work, we have developed a generic model for the average particle fluxes at t...
Recent advances in volume electron microscopy (vEM) allow unprecedented visualization of the electron-dense structures of cells, tissues and model organisms at nanometric resolution in three dimensions (3D). Light-based microscopy has been widely used for specific localization of proteins; however, it is restricted by the diffraction limit of light...
