In order to substantiate the applicability of the Takayama-Lin-Liu-Maki model to conducting polymer,the Su-Schrieffer-Heeger model is generalized to include the effects of lattice zero-point motions on electronic *** the treatment of the white-noise approximation,some significant electronic properties of Peierls-Fröhlich states are *** finding shows that the correlation of lattice motions suppresses the effects of zero-point motions on the electronic properties more seriously.

Scanning tunneling microscopy study revealed a van der Waals C60, solid film with 13% room-temperature lattice expansion on the GaAs(001) 2×4 surface. The mechanism involves fundamental Coulomb interaction due to charge transfer from the GaAs substrate. Theoretical calculation determines the charge transfer to be 1.76 electrons per C60 molecule. Oriented at its (110) crystallo-graphic axis this film also distinguishes itself from those formed on all other semiconductor and metal substrates where only the low-energy (111) hexagonal packing of C60 molecules was developed. It is shown that this is due to the one-dimensional confinement effect of the anisotropic substrate, which may have the prospect of controlling crystal growth.

＜正＞Effect of self-preservation of gas hydrates was explored over many years but there is no complete understanding how can hydrates exist in their thermodynamic instability region. We are suggesting the microscopic-level model of methane hydrate clusters immersed in ice matrix. Due to differences in thermal expansion of methane hydrate and Ice Ih the additional pressure appears in the hydrate phase and this moves it into its stability field. MD simulations were performed to find local pressure and density profiles. Results are well confirming our assumption.

Two-dimensional (2D) multiferroics have attracted increasing interests in basic science and technological fields in recent ***,most reported 2D magnetic ferroelectrics are based on the d-electron magnetism,which makes them rather rare due to the empirical d^(0) rule and limits their applications for low magnetic phase transition *** this work,we demonstrate that the ferroelectricity can coexist with the p-electron-induced ferromagnetism without the limitation of d^(0) rule and metallicity in a family of stable 2D MXene-analogous oxynitrides,X_(2)NO_(2) (X = In,Tl).Remarkably,the itinerant character of p electrons can lead to the strong ferromagnetic metallic ***,a possible magnetoelectric effect is manifested in a Tl_(2)NO_(2)/WTe_(2) heterostructure through the interface *** findings provide an alternative possible route toward 2D multiferroics and enrich the concept of ferroelectric metals.

Hypertension is one of the most important modifiable risk factors for stroke,and greater than 50%of all stroke events are estimated to be attributable to elevated blood pressure(BP).Randomized trials and meta-analyses have demonstrated that reducing BP is the most effective and generalizable strategy for preventing recurrent *** on currently available evidence,BP should be reduced to below 140/90 mmHg in all patients during the chronic post-stroke phase and to below 130/80 mmHg when welltolerated.
