We present a numerical study of the statistical properties of the potential energy landscape of a simple model for strong network-forming liquids. The model is a system of spherical particles interacting through a square-well potential, with an additional constraint that limits the maximum number of bonds Nmax per particle. Extensive simulations have been carried out as a function of temperatur...

In this study, a temperature-dependent of the dispersion coefficients is calculated from equation state.The Lennard-Jones LJ (12-6-3) effective pair potential function and simple thermodynamic argumentwith the input PVT data of liquid metals are used to calculate the dispersion coefficients. The dispersioncoefficients ( , , ) 3 6 12 C C C are found to be a linear function of 1/T1+α , where T is...

in this research work, the dissolution of chalcopyrite was investigated under atmospheric pressure, with sulfate media at low temperatures, in 30°c to 50°c. in the galvanic interaction between chalcopyrite and pyrite, pyrite is used as a leaching catalyst. effects of different parameters such as temperature, stirring speed, pyrite to chalcopyrite ratio, particle size, and solution potential wer...

germination is series of biochemical reactions that depends mainly on temperature and moisture. therefore, seed germination rate of lemon balm (mellissa officinalis l.) were evaluated in temperatures of 20, 23, 25,27, 30 and 32ºc and water potentials of 0, -0.2, -0.4, -0.6 and -0.8mpa. according to the results, germination temperature window was not very wide in a way that germination temperatu...

water and temperature are determinant factors for seed germination. both factors can, separately or jointly, affect the germination percentage and germination rate. the effect of temperature on germination and water potential on germination can often be described by the thermal time and hydrotime models, respectively. additionally, the thermal time model and the hydrotime model have been combin...

The objective of this study is to design and analyse materials which are capable of harvesting water from thin air using condensation phenomenon which employs the radiative cooling approach. These passive cooling materials not only solve the water generating problems, but also employed in various cooling applications. The fundamental concept of radiative cooling is analysed and the performance ...

this paper addresses the annealing temperature effect on nanostructure and phase transition of copper oxide thin films, deposited by pvd method on glass substrate (at 110 nm thickness) and post annealed at different temperatures (200-400°c) with a flow of 1 cm3s-1 oxygen. the x-ray diffraction (xrd) was employed for crystallographic and phase analyses, while atomic force microscopy (afm) was us...
