Evidence of a Proximity Effect in a (AgI)_x − C_(1−x) Mixture Using a Simulation Model Based on Random Variable Theory

Molecules
Silver iodide is a prototype compound of superionic conductors that allows ions to flow through its structure. It exhibits a first-order phase transition at 420 K, characterized by an abrupt change in its ionic conductivity behavior, and above this ...

Glass Transition Temperatures in Polymer Mixtures [PDF]

Polymer Journal, 1986
A fluid-lattice theory of fluid mixtures is combined with the Gibbs-DiMarzio approach of zero configurational entropy at glass transition in order to correlate and predict the composition dependence of glass transition temperature, Tg, in one-phase polymer mixtures. Such a combination allows an independent quantitative estimation of the significance to

BAND STRUCTURE OF RUTHENATE SUPERCONDUCTORS

TASK Quarterly, 2011
We investigate the band structure of ruthenates using the first-principles method of density functional theory (DFT). We calculated the band structure and density of states at the Fermi level for superconductors Ba2YRuO6 and Sr2YRuO6.

Determining Hole Locations in High-Temperature Superconductors via Spectral Analysis of Gap Tensor Parameters

Proceedings of the International Conference on Applied Innovations in IT
The nuclear quadrupole resonance (NQR) method using 63,65Cu isotopes allows for the experimental determination of the total electric field intensity (EFI) on 63,65Cu nuclei in the lattices of high-temperature superconductors (HTSC).

A novel method for characterizing temperature-dependent elastic modulus and glass transition temperature by processing the images of bending cantilever slender beams at different temperatures

AIP Advances, 2018
We propose a novel method for estimating the elastic modulus of several materials by processing the bending image of cantilever material sheets. The calculated results (tested for five samples) were consistent with data obtained by direct measurement ...

Zero-temperature glass transition in two dimensions

Nature Communications, 2019
Identifying the nature of the glass transition is challenging because relevant experiments or analytical descriptions are hard to achieve. Here, Berthier et al.

Effects of phase-transition heat on fracture temperature in self-propping phase-transition fracturing technology

Petroleum Exploration and Development
The thermal flux curve of phase-transition fluid (PF) was tested using differential scanning calorimetry, based on which a reaction kinetics model was established to reflect the relationship between phase transition conversion rate, temperature and time.

Mercurocuprates: The Highest Transition-Temperature Superconductors

, 1997
With these words [1] Heike Kamerlingh-Onnes summarised the existence of “a new state” of mercury. This discovery (initially made in 1911 [2]) gave the world the first superconductor — elemental mercury — which entered this new state of matter below a superconducting transition temperature (Tc) of 4.2K.
