The preparation process of silica aerogels has commonly involved a dangerous supercritical drying step, so work has been done to eliminate this step. This paper discusses the preparation of composite silica aerogels containing silica fibers using a method that excludes the supercritical drying step. The ...
Through the addition of graphite powder (GP) and expanded graphite (EG) the authors were able to increase the thermal conductivity of a shape-stabilized paraffin/high density polyethylene (HDPE) composite phase change material (PCM). GP and EG were added in different mass fractions and a Thermal ...
The 'graphene-like' mechanical exfoliation of Bi2Te3 films is shown to have a significant effect on the thermoelectric properties of these films. The modification of thermal conductivity due to exfoliation leads to enhanced thermoelectric properties, known as figures of merit (ZT).Two different experimental techniques ...
