The following values are obtained: 2Δ(0)=0,65 meV, T c =2,11 K for the amorphous state after quenched condensation and 2Δ(0)=1,24 meV, T c =4,06 K for the crystalline state after annealing at room temperature. The reduced energy gap 2Δ(0)/ kT c =3,58 demonstrates that ...
Elastic constants of B-HMX and tantalum, equations of state of supercritical fluids and fluid mixtures and thermal transport determinations Ultrasonic sound speed measurements via Impulsive Stimulated Light Scattering (ISLS) were made in single crystals of b-HMX and tantalum over an extended ra... ...
The superconducting transition temperature of a high-purity sample of tantalum has been measured and a zero-field value of 4.457°K+/-0.003°K obtained. The ratio of room temperature resistivity ρto the residual resistivity ρgave a measure of the purity of the sample, a value of 250 being...
in sharp contrast with that of MoS2that posseses inert surface catalytic properties37. It is worth mentioning that, Yakobson, B. I. et al. have demonstrated that the populated state of electrons near the lowest unoccupied
temperature range 600–750 °C because of their relatively high mixed conductivities23,24. The perovskite structure of SC, which is favoured for ORR, is usually stabilized by partialB-site substitution with high oxidation-state cations25, such as Nb26,27, Mo28, Sb29,30and P31,32, and ...
Weyl semimetal state in TaP single crystal TaP has a body-centred-tetragonal structure without inversion symmetry (space group I41md), depicted inFig. 1a. The lattice parameters obtained from our X-ray diffraction measurement at room temperature area=b=3.32 Å andc=11.34 Å (seeSupp...
The measurements were performed in air at room temperature using contact mode and static force operation mode. Easy Drop Shape Analyzer (DSA1, KRÜSS GmbH, Hamburg, Germany) was used to measure the contact angle of Millipore water on the prepared films at 24 °C in air. The samples were ...
Multiple phenomena, such as the removal rate from the surface, the matter velocity towards the interface surface, the chemical reactions, the conditions concerning the heat transfer, etc., taking place at this interface influence the overall rate of reactions. The rate of some processes, such as...
