Tailoring the Electrical Energy Storage Capability of Dielectric Polymer Nanocomposites via Engineering of the Host–Guest Interface by Phosphonic Acids

open access: yesMolecules, 2022
Polymer nanocomposites have attracted broad attention in the area of dielectric and energy storage. However, the electrical and chemical performance mismatch between inorganic nanoparticles and polymer leads to interfacial incompatibility. In this study,

An engineering approach to modelling of dynamic insulation using ESP-r [PDF]

open access: yes, 2003
The use of Dynamic Insulation (DI) can enable recovery of conduction heat loss through a building envelope. This is an active process that allows air to move through the fabric against the temperature gradient.

Moisture Accumulation and Its Impact on the Thermal Performance of Pipe Insulation for Chilled Water Pipes in High Performance Buildings [PDF]

open access: yes, 2012
Mechanical pipe insulation systems are commonly applied to cold piping surfaces in most industrial and commercial buildings in order to limit the heat losses and prevent water vapor condensation on the pipe exterior surfaces.

Annual assessment of highway traffic noise using two channel short-term measurements

open access: yesTransport, 2014
Research has shown that for residential area nearby (up to 50 m) exurbia roads, there are cases where the evaluation of noise impact needs more than using the calculation methods alone.

Development of an ecological thermal insulation product for a regenerative design [PDF]

open access: yes, 2023
Although thermal insulation materials contribute to reducing energy demand, the most used materials have high embodied energy. Bio-based thermal insulation products stock CO2 and therefore have lower embodied energy.
