A solar simulator was used to test whether a carbon black additive could increase the solar absorption of a low temperature organic PCM (consisting of a eutectic mixture of palmitic acid and stearic acid).
Various PCM and ...

Rapid prototyping techniques are quickly advancing to become market leading
manufacturing techniques in terms of: product availability, cost effectiveness and
environmental impact. In addition, they are also rendering ...

It is unclear whether all intercalation techniques truly lead to the insertion of atoms
between the graphite layers, or also lead to other effects which contribute to expansion.
The objective of this project is to better ...

Roberson, Albert
(University of Pretoria, 2018)
A promising energy harvesting technique involves the use of thermal nanofluids, capable of collecting solar UV/visible radiation and storing it as latent heat in phase change materials (PCM), i.e. molten salts. Carbon-based ...
