Testing of loop heat pipes showed that the heat-load dependence operating temperature was not always unambiguous. It may have hysteresis phenomena. The had a certain relationship with previous history power variation, and also related to initial parameters pipes. has been found gas-liquid distribution in compensation chamber which depended on interaction between leak evaporator reflux liquid fr...

The stability of 10 active pharmaceutical ingredients was studied in SyrSpend SF PH4 or SyrSpend SF Alka at room and/or refrigerated temperature (2°C to 8°C). An oral suspension of each active pharmaceutical ingredient was compounded in low actinic plastic bottles at a specific concentration in SyrSpend SF PH4 or SyrSpend SF Alka. Samples were assessed for stability immediately after preparatio...

Abstract The composite precipitation of Ti 2 O 3 + TiN during continuous casting has an important influence on the microstructure and properties slab. In order to study conditions , TiC second phase in titanium microalloyed steel, solid-liquid line temperature, initial temperature different phase, equilibrium actual solubility product at temperatures are calculated, rules steel liquid two-phase...

The low-temperature dynamics of ultraviscous liquids hold the key to understanding the nature of glass transition and relaxation phenomena, including the potential existence of an ideal thermodynamic glass transition. Unfortunately, existing viscosity models, such as the Vogel-Fulcher-Tammann (VFT) and Avramov-Milchev (AM) equations, exhibit systematic error when extrapolating to low temperatur...

We present the results of a combined experimental and theoretical study of drop coalescence in the presence of an initial temperature difference 1T0 between a drop and a bath of the same liquid. We characterize experimentally the dependence of the residence time before coalescence on 1T0 for silicone oils with different viscosities. Delayed coalescence arises above a critical temperature differ...

We study low temperature properties of a spinless interacting Fermi gas in the trimerized kagomé lattice. The case of two fermions per trimer is described by a quantum spin 1/2 model on the triangular lattice with couplings depending on the bond directions. Using exact diagonalizations we show that the system exhibits nonstandard properties of a quantum spin-liquid crystal, combining a planar a...

By analyzing the experimental data for various glass-forming liquids and polymers, we find that the nonexponentiality, beta, and the relaxation time, tau, are commonly related: log(tau) is an approximately linear function of 1/beta, followed in most cases by a crossover to a higher linear slope. We rationalize this relationship in the recently developed elastic approach to the glass transition....

Objective(s):This study dealt with the wet agglomeration process in which a small quantity of binder liquid was added into a suspension of crystals, directly in the stirring vessel where the crystallization took place. The purpose of this investigation was evaluation of the effect of temperature on the agglomeration process in order to gain insight into the mechanism of the formation of the agg...

A novel liquid chromatographic system which enables high temperature ultrafast liquid chromatography (HTU-FLC) has been designed through the careful consideration of heat transfer, band broadening, and pressure drop. Studies of the effect of linear velocity on the HETP show that column efficiency at high velocity, especially of well-retained solutes, dramatically improves at higher temperatures...

This study concerns the performance of cocoons spun by silk worms as a natural ‎adsorbent for removal of Methylene Blue (MB) from aqueous solutions. To study the adsorption ‎process, the effect of various parameters such as contact time, adsorbent dosage, dye initial ‎concentration, and pH of the solution were investigated. According to the experiments, the kinetic ‎data were best described by ...
