the present study was carried out to investigate the potential of carboxylate group functionalized multi-walled carbon nanotubes (mwcnt−cooh) adsorbent for the removal of methyl orange (mo) textile dye from aqueous solutions. the effects of ph, shaking time and temperature on adsorption capacity were studied; the contact time to obtain equilibrium at 298 ˚k was fixed at 25 min. the effect of te...

Due to the fact that many application processes take place at different temperature, better examining and understanding of swelling properties as a function of temperature is essential for such application. The temperature effect on the swelling properties of commercial polyacrylic acid (PAA) hydrogel beads was investigated as a function of time and temperature. Gel bead size, swelling equilibr...

We analyze temperature and thermometry for simple nonequilibrium heat-conducting models. We also show in detail, for both twoand three-dimensional systems, that the ideal-gas thermometer corresponds to the concept of a local instantaneous mechanical kinetic temperature. For the 4 models investigated here the mechanical temperature closely approximates the local thermodynamic equilibrium tempera...

We report the results of a kinetic investigation on the gelation of purified deoxyhemoglobin S. Gelation was induced by raising the temperature and was monitored by measuring both the heat absorbed, with a microcalorimeter, and the appearance of linear birefringence, with a microspectrophotometer. The kinetics are unusual. Prior to the onset of gelation there is a delay period, followed by a si...

reaction constants and heat release during thermophilic aerobic digestion of typical secondary and mixed sludges were determined. maximum reaction constant, determined by measuring the amounts of biodegradable volatile suspended solids (bvss) removed, occurred in the temperature range of 55-60 ºc. measurement of heat releases were carried out, at the same range, by the aid of a temperature prog...

This paper deals with a theoretical mathematical analysis of one-dimensional solidification problem, in which kinetic undercooling is incorporated into the This temperature condition at the interface. A model problem with nonlinear kinetic law is considered. We prove a local result intimate for the uniqueness of solution of the corresponding free boundary problem.

The kinetics of electron attachment to CF(3) as a function of temperature (300-600 K) and pressure (0.75-2.5 Torr) were studied by variable electron and neutral density attachment mass spectrometry exploiting dissociative electron attachment to CF(3)Br as a radical source. Attachment occurs through competing dissociative (CF(3) + e(-) → CF(2) + F(-)) and non-dissociative channels (CF(3) + e(-) ...

Hetero-epitaxial growth on a strain-relief vicinal patterned substrate has revealed unprecedented 2D long range ordered growth of uniform cobalt nanostructures. The morphology of a Co sub-monolayer deposit on a Au(111) reconstructed vicinal surface is analyzed by Variable Temperature Scanning Tunneling Microscopy (VTSTM) experiments. A rectangular array of nano-dots (3.8 nm x 7.2 nm) is found f...

Using the technique of impedance spectroscopy, data on effect magnitude variable signal and constant bias kinetic characteristics Ag x MoSe 2 samples were obtained. The temperature parameters spectra studied compounds their dielectric characteristics, which analyzed within framework electrical modulus formalism, is also shown. Keywords: impedance, intercalates, molybdenum diselenide, silver, pe...
