Temperature dependent excitonic effects in silicon
… behaviour and the material’s bandgap. When the temperature rises, the excitonic effect is not completely dissipated but rather immersed in a thermally broadened spectrum. Thus, a highly accurate and sensitive characterisation tool needs to be developed to investigate the material’s excitonic and …

Model Predictive Control for Temperature Dependent Systems
<p>Manipulating and monitoring the variables of temperature dependent systems can be a very complex task for most industrial facilities since they require either the close attention of experienced engineers or highly expensive control programs. These systems are often poorly operated, which …

Temperature dependent magnetic order in FeOCl type compounds
The present work reports on the behaviors of temperature-dependent magnetic order of the transition-metal oxychlorides MOCl (M = Ti, Cr, Fe); further studies were performed on scandium-doped TiOCl and sodium-intercalated TiOCl. Single crystals of MOCl were grown by the chemical vapor phase …

MEMS-based temperature-dependent characterization of biomolecular interactions
… for a wide variety of biological processes. Temperature dependence is a ubiquitous effect for biomolecular interactions as most biological processes are thermally active. Understanding the temperature dependence of biomolecular interactions is hence critical for a wide variety of applications …

Temperature-Dependent Supramolecular Remodeling of Poly-Ether Perylene Diimides
… phase-separated aggregates, in a thermally dependent and reversible manner within aqueous solution. The investigation into TEL-045 characterizes and examines the molecular basis of its entropically-driven self-assembly and its ability to switch between aggregation types in this unnatural …

Investigation Of Temperature Dependent Magnetic Hyperthermia In Fe3o4 Ferrofluids
… spins could be used to elevate local tissue temperature to about 46 ˚C to arrest cancerous growth. MHT, due to its local nature of heating, when combined with other forms of treatment such as chemotherapy and/or radiation therapy, it could become an effective therapy for cancer treatment. The …

Temperature dependent dynamic response of open-cell polyurethane foams
… under strain rates of 10$^2$ s$^{-1}$ and under temperature conditions ranging from -20 to 40\textdegree{C}. This temperature range was chosen to simulate desert and arctic conditions, with a strain rate regime chosen to represent loads that would occur often throughout the life of the helmet, …

Temperature-dependent tensile and shear response of graphite/aluminum
… (v<sub>f</sub> = 0.47) was investigated at four temperatures: -150°F, +75°F, +250°F and +500°F, using test methods developed at Virginia Tech. Two types of tests, off-axis tension and Iosipescu shear, were used to obtain the desired properties. Good experimental-theoretical correlation was …

Strain rate and temperature dependent mechanical behavior of nanocrystalline gold
… in the large range of operating strain rates and temperatures. This dissertation research studied (a) the role of thermally activated processes based on the strain rate and temperature dependent mechanical behavior of nanocrystalline Au thin films, and (b) deformation processes at nominally …

Nonlinear temperature dependent failure analysis of finite width composite laminates
… studied. Curing stresses are calculated using temperature dependent elastic properties that are input as percent retention curves, and stresses due to mechanical loading in the form of an axial strain are calculated using tangent modulus, obtained by Ramberg Osgood parameters. It is shown that …

An Invertible Open-Loop Nonlinear Dynamic Temperature Dependent MR Damper Model
… command signals by capturing the effect of temperature on a MR Damper's performance capabilities. Furthermore, this solution is specifically tailored for real-time application and does not require force feedback. Thus it requires low computation power and minimizes end-user cost by …

Solar Cell Temperature Dependent Efficiency and Very High Temperature Efficiency Limits
… is significantly lower than their peak operating temperature. In some thermal concentrating systems, solar cells operate above 300 °C. Since increasing the temperature drastically affects the terminal characteristics, it is important to quantify the losses caused by raising the temperature. …

THERMAL CONDUCTIVITY OF THIN FILM NIOBIUM DISELENIDE FROM TEMPERATURE-DEPENDENT RAMAN
… k=15(+4/-4) W/mK was obtained at room temperature and we further verified by hall measurements that (NbSe2) conducts heat mostly through electrons. The results shed lights on the potential of Niobium diselenide as a thermoelectric device.

The Influence of Curvature on Mantle Convection featuring a Temperature-dependent Viscosity
… planets and moons is characterized by a strongly temperature-dependent viscosity. Mantle convection regime is first examined in 2D and 3D spherical geometry with varying mantle curvature (core-to-surface radii-ratio, f) and constant heating conditions and viscosity contrast across the mantle depth …

Plume formation in strongly temperature-dependent viscosity fluids: Application to early Mars
… unusual fluids whose viscosity varies with temperature by many orders of magnitude. Plume formation in such fluids is a complex and poorly understood phenomena. Thus, we begin with a systematic two-dimensional numerical and theoretical investigation of plume formation in strongly …
