Chinese students represent a substantial portion of the UK university student population, with most of them being postgraduates. However, whilst the UK rem
These can be in the form of sensible TES materials (STESMs), latent heat TES (LHTES) using phase change materials (PCMs) (which are thermophysical materials) or thermochemical TES (TCS) using thermochemical heat storage materials (TCMs). Water is the most abundant, cheapest, most known and ...
Indeed, the walls on which contemporary murals are created need to breathe and allow the water to evaporate, while with these systems, water vapour permeability can be severely compromised, leading also to the acceleration of other deterioration mechanisms, such as salt crystallisation and freeze-...
