We have investigated the noble gas distribution within a single vesiculated sample. Our results indicate that two components are present: one, located inside the vesicles, is likely to be mantle-derived; the other, dissolved in the glass, displays evidence of atmospheric contamination...
Ultrathin and flat crystals of bismuth are grown between the atomically flat layers of a van der Waals material. These crystals exhibit outstanding electronic properties, including gate-tunable quantum oscillations of the magnetoresistance. Laisi Chen , Amy X. Wu & Javier D. Sanchez-Yamagishi News...
The untight contact interface and lattice mismatch are still the “bottleneck” of heterojunction systems [29]. Recently, van der Waals (VdW) heterostructures that are composed of two or more two-dimensional materials have attracted much interest due to their unique properties including tunable electr...
experimental values well.Comparing with molecular simulation and the other density functional models in which only two-body intermolecular interaction is included,these results show that the three-body intermolecular interaction has significant influence on the structures and properties of inhomogeneous fluids...
Measurements are presented of the collisional relaxation of two-pulse echoes on the 455 nm and 459 nm D-lines of atomic caesium perturbed by low pressures of He, Ar and Xe using the echo-polarisation rotation technique, with interpulse times up to approximately 200 ns. The line broadening ...
3). The hydrodynamic and electrochemical properties of RDE are related to the Koutecky-Levich (K-L) equation [50].(24)1J=1JK+1JL=1nFkC0+10.62nFC0D032v−16w12where jK and jL are the kinetic-limiting current density and diffusion-limiting current density (mA cm−2), n stands for...
However, a fully ligated T-quaternary structure of human normal Hb has not been reported by NMR so far. In the present study, we aim to clarify the various structural interpretations about the binding properties of L35 and IHP to Hb by using NMR spectroscopy. 2. Materials and methods All ...
We demonstrate how these rules depend on the laser parameters and how they can be used in the experiment to shape the polarization properties of the emitted attosecond pulses. 展开 关键词: Control attosecond light DOI: 10.1103/PhysRevA.97.023409 ...
Ag(I) salts are commonly employed in organic transformations by exploiting three main properties (Fig. 1). First, its moderate Lewis acidity has found application in activating allenes and alkynes to promote a nucleophilic attack over the unsaturation to render, for instance, the cyclization of ...
In general, 2D metallic materials are supposed to show distinct molecular activation ability and catalytic behaviours, considering that they have unusual electronic structures as well as a large proportion of low-coordinated atoms. However, only molecular adsorption properties have thus far been ...
