Ink Transfer

The effect of temperature on the ink transfer of sublimation printing technology was investigated. The ink transfer was conducted by the colour density of single solid inks and the ink trapping of overprinted solid inks. The experimental results indicate that the amount of ink transferred from the colour ribbon to the substrate is determined by the thermal characterization of dye materials. The densities of single colour inks as well as the ink trapping coefficients obtain the highest values at the temperature corresponding to the endothermic peaks of the dye materials. This is the optimum operating processing temperature.

This study is an experimental and numerical analysis of the influence from changes in the conditions of inputs temperature and velocity on the behavior thermal and dynamic of a multi-jet swirling system impacting a flat plate. The experimental device comprising three diffusers arranged in line, of diameter D aloof 2D between the axes of their centers, impinging the plate perpendicularly at an impact height H = 6D. The swirl is obtained by a generator (swirl) of composed 12 fins arranged at 60° relative to the vertical placed just at the exit of the diffuser. By imposing the temperature and velocity for three input conditions with three studied configurations. The paper deals with find the configuration that optimizes the best thermal homogenization. The results show that the configuration having an equilibrated inlet temperature (T, T, T) is derived from a good temperature distribution on the baffle wall and a better thermal transfer from the plate. The system was numerically simulated by the fluent code by using the turbulence model (k–ε). This last has yielded results accorded to those experimental results.

There has been significant work on use of MEMS for biomedical applications in the past few years. This work presents a microheater device for use in experiments to study the effect of temperature on nerve cell growth. The device consists of a thin membrane with embedded heater and temperature sensors. Nerve cells could be immobilized on the membrane surface and their growth behavior could be studied by applying different heating powers, the goal being the actuation and control of cell growth using temperature. This work presents the design and fabrication of the microheater device being used in these cell growth experiments. Experimental data and finite element modeling are used to characterize the thermal response of the device. This yields a low value of the membrane thermal conductivity which indicates the amorphous nature of the thin film.

In this paper was studied effect of temperature on the trans-resveratrol till to total degradation by UV-Vis spectrophotometry and FT-IR spectroscopy. Using statistical methods, it was observed that trans-resveratrol is unstable to higher temperatures than 100 �C, even in the absence of light. However, at temperatures up to 70 � C, resveratrol was found to be enough stable for time periods as short as 30 min. Pearson correlations of absorbance values at 304 nm (characteristic for trans-resveratrol) and 286 nm (characteristic for cis-resveratrol) shown that no conversion of trans-resveratrol to cis resveratrol is produced at elevated experimental temperatures.

This study highlights the thermal characterization of ABS-Graphene blended three dimensional (3D) printed functional prototypes by fused deposition modeling (FDM) process. These functional prototypes have some applications as electro-chemical energy storage devices (EESD). Initially, the suitability of ABS-Graphene composite material for FDM applications has been examined by melt flow index (MFI) test. After establishing MFI, the feedstock filament for FDM has been prepared by an extrusion process. The fabricated filament has been used for printing 3D functional prototypes for printing of in-house EESD. The differential scanning calorimeter (DSC) analysis was conducted to understand the effect on glass transition temperature with the inclusion of Graphene (Gr) particles. It has been observed that the reinforced Gr particles act as a thermal reservoir (sink) and enhances its thermal/electrical conductivity. Also, FT-IR spectra realized the structural changes with the inclusion of Gr in ABS matrix. The results are supported by scanning electron microscopy (SEM) based micrographs for understanding the morphological changes.
