Soil freezing characteristic curve (SFCC) represents the relationship between soil temperature and unfrozen water content of during thawing processes. In this study, SFCC sandy soils was determined in laboratory. Pure sand mixed with clay at various contents (0, 5, 10, 15, 20% total dry mass), mixtures were compacted to their respective maximum density. Compacted specimens then placed a close r...

in this paper, the nucleation and growth of diamond/diamond-like coatings on austenitic (aisi 316) and ferritic (aisi 430) stainless steel substrates have been investigated using torch technique. the effects of substrate surface preparation has also been studied. the quality of coatings produced has been examined using optical and scanning electron microscopy, x-ray diffraction, raman spectrosc...

The study of the micro-plastic behavior of rough surface contact is the critical link towards a fundamental understanding of contact, friction, adhesion, and surface failures at small length scales. In the companion paper (Yu et al., J. Mech. Phys. Solids 55, 489-516, 2007), we have studied the onset of surface yielding due to single-dislocation nucleation from a stepped surface under adhesive ...

Abstract We report on the fabrication of Josephson junction devices with weak links utilizing Weyl and higher-order topological semimetal WTe 2 . show that /Pd contact annealed at a low temperature 80 °C did not exhibit superconducting properties because neither nor Pd are superconductors in ground state. Upon 180 annealing, spontaneous formation PdTe due to diffusion enabled us obtain interfac...

The colloidal nature of perovskite precursor solution highly determines the quality film and photovoltaic performance a solar cell (PSC). Herein, we demonstrate facile method to fabricate high-quality all-inorganic CsPbIBr2 by regulating temperature solution. After characterization, stable microcrystals with size up 1 have been formed under high temperatures, more suitable for preferable crysta...

Weakly coupled semiconductor superlattices under dc voltage bias are excitable systems with many degrees of freedom that may exhibit spontaneous chaos at room temperature and act as fast physical random number generator devices. Superlattices identical periods current self-oscillations due to the dynamics charge dipole waves but chaotic oscillations exist on narrow intervals. They disappear eas...
