The isothermal decomposition of a new material with high energy, namely N-guanylurea dinitramide (FOX-12), was studied by a self-established isothermal decomposition gas metering device. The gas pressure versus time curves of the isothermal decomposition of FOX-12 were obtained at temperature intervals within 120 °C and 170 °C. An extremely long lag phase and acceleration period were found in the decomposition process of FOX-12. The kinetic parameters of FOX-12 were obtained by the Arrhenius equ...

In the present study, the lattice Boltzmann method (LBM) is employed to study the diffusion phenomenon in solid oxide fuel cell (SOFC) with direct internal reforming (DIR). The main focus of this work is to correlate and estimate the diffusion coefficient through dimensionless numbers, i.e., Schmidt and Prandtl. This work tries to reveal the importance of reforming and electrochemical reactions on these dimensionless numbers in active and inactive zones. In addition, the effects of inlet velocit...

Cooling of electronic devices is one of the critical challenges that the electronics industry is facing towards sustainable development. Aiming at lowering the surface temperature of the heat sink to limit thermally induced deformations, corrugated channels and nanofluids are employed to improve the thermal and hydraulic performances of a heat sink. Three-dimensional simulations based on the finite-volume approach are carried out to study conjugated heat transfer in the heat sink. Water-based na...

This research article presents an experimental performance comparison of three cases, viz (1) conventional solar still, (2) single slope solar still incorporated with parabolic trough collector, and (3) single slope solar still incorporated with parabolic trough collector and packed layer of glass balls in the basin. The resulting heat due to incident solar energy on the parabolic trough collector is transferred by means of a finned piped (steel) loop heat exchanger that is immersed in the still...

The thermal analyses of Au–35 mass% Ag–15 mass% Cu alloy show different phase transformations (order-disorder transition and precipitation reaction) which have not been well identified before. It is known that the physical properties of this alloy depend on the crystalline and microstructural changes. Thus, to identify all phases optical microscopy, X-ray diffraction (XRD), differential scanning calorimetry, scanning electron microscopy and high-resolution transmission electron microscopy are us...

The stator ventilation duct is the main path for fluid flowing to cool the stator bar and the core. Considering the complexity of the ventilation system, the investigation on the relationship between the air motion law in the ventilation duct and its surface heat transfer coefficient is crucial for the accurate calculation of the temperature field. Therefore, this paper takes the 150 MW air-cooled turbo-generator as a research object. Firstly, a new calculation model of the stator taking the air...

In our present research work, we have investigated the different thermal, optical and electrical properties of Se85In15−xBix alloys in bulk and thin film form. Differential Scanning Calorimeter (DSC) was operated at different heating rates of 5, 10, 15, 20 and 25 K min−1. The melting temperature (Tm), peak crystallization (Tp), on-set crystallization (Tc) and glass transition (Tg) temperature were evaluated from DSC curves. The value of Tg, Tc and Tp was found to increase with the heating rate. ...

We present experimental data on water repetitively brought in contact with cellophane. Although this hydrophilic polymer is insoluble in water, repetitively immersing it in water changes the liquid’s properties. We compare the physicochemical properties of the water left over after removing the cellophane to those of previously published data on water repetitively brought in contact with other in water insoluble polymers (cotton wool or Nafion). Some of the properties are similar. All the proper...

The compounds having two or more antioxidant functions in their structure exhibit antioxidant synergism that generally increase the antioxidant activity of these compounds. In this study, two series of semicarbazone (7a–j and 7a′–j′) bearing butylated ortho and para hydroxy benzylidene ring were prepared for the investigation of antioxidant synergism. This study found that intramolecular hydrogen bond can form in semicarbazones due to the inappropriate position of hydroxyl group on benzylidene r...

In order to study the effect of MWCNTs on the crystallization of UHMWPE, the UHMWPE nanocomposites filled by MWCNTs with high content were prepared by solution method. The non-isothermal and isothermal crystallization of MWCNTs/UHMWPE nanocomposites were studied by differential scanning calorimetry and X-ray diffraction. The results showed that the heterogeneous nucleation of MWCNTs increases the crystallization temperature and crystallinity of UHMWPE filled by MWCNTs below 40 mass% with the inc...
