Self-Healing Phase Change Salogels with Tunable Gelation Temperature

ACS Applied Materials & Interfaces, 2018
Chemically cross-linked polymer matrices have demonstrated strong potential for shape stabilization of molten phase change materials (PCM). However, they are not designed to be fillable and removable from a heat exchange module for an easy replacement with new PCM matrices and lack self-healing capability.

Economic Studies on High-Temperature Phase Change Storage Systems

2018
In this chapter cost comparisons of encapsulated phase change materials (EPCMs), coil-in-tank, and heat pipe thermal energy storage systems are reviewed. Due to the increased interest in this field there are a number of studies on the economics of the aforementioned systems.

A database of lipid phase transition temperatures and enthalpy changes

Chemistry and Physics of Lipids, 1991
The systematic study of the mesomorphic phase properties of synthetic and biologically derived lipids began some 30 years ago. In the past decade, interest in this area has grown enormously. As a result, there exists a wealth of information on lipid phase behavior, but unfortunately, these data have, until now, been scattered throughout the literature ...

Thermal Conductivity of High-Temperature Multicomponent Materials with Phase Change

International Journal of Thermophysics, 2007
This work focuses on the investigation of the effective thermal conductivity (λeff) of heterogeneous materials consisting of a phase change material (PCM) and expanded graphite (EG). These composites may be employed in latent heat storage systems, where a PCM stores energy by being heated to a temperature higher than its melting point (T

Compensating temperature-induced ultrasonic phase and amplitude changes

SPIE Proceedings, 2016
In ultrasonic structural health monitoring (SHM), environmental and operational conditions, especially temperature, can significantly affect the propagation of ultrasonic waves and thus degrade damage detection. Typically, temperature effects are compensated using optimal baseline selection (OBS) or optimal signal stretch (OSS). The OSS method achieves

Phase Changes of Multielemental Alloy Nanoparticles at Elevated Temperatures

ACS Nano
Multielemental alloy (MEA) nanomaterials, such as medium and high entropy alloys, display promising catalytic performance in a range of chemical reactions due to their multicomponent structural configurations. These complex structural and chemical arrangements can be influenced by several factors, such as mechanical stress, irradiation, and high ...

MMIC temperature stabilization through phase change energy absorption

IEEE International Digest on Microwave Symposium, 2002
A novel temperature stabilization concept for MMICs (monolithic microwave integrated circuits) utilized in applications such as decoys, kinetic energy weapons, missile systems, and smart munitions is presented. The concept permits MMIC junction temperatures to be maintained within operational limits during short periods of high power dissipation.

Phase Change Problems With Temperature-Dependent Thermal Conductivity

Journal of Heat Transfer, 1974
An exact solution is presented for the temperature distribution and phase change position of a semi-infinite body which is initially at a constant temperature different from the fusion temperature. The temperature of the free surface is instantaneously changed and held constant at a value that will cause either melting or solidification of the body ...
