Summary: Phase change materials (PCM) can reduce energy consumption and improve thermal comfort in buildings. However, there are limitations in integrating PCM into construction materials, primarily due to the selection of suitable porous materials. This study aimed to select the most suitable porous material for developing Form Stable PCM (FSPCM) cement composite for concrete panels in building envelopes. Five different porous materials were considered based on their porosity, geometry, and surface morphology, and the performance of the synthesized FSPCM composite was evaluated. The study revealed that silica aerogel granules (SAG) had the highest PCM absorption capacity, while recycled expanded glass (REG) had lower absorption capacity. The Capric Acid/Hydrophobic expanded Perlite (CAHEP) showed the best overall performance in terms of absorption, thermal conductivity, strength, thermal inertia, latent heat storage, and thermal storage.

Summary: Passive latent heat storage for building applications utilizes phase change materials (PCMs) to reduce energy consumption and provide thermal comfort. Integration of PCMs in building envelopes can reduce peak temperature and smooth thermal load, but challenges remain in studying long-term stability, moisture, mass transfer, and actual building use. The use of fatty acids and eutectic mixtures in shape-stabilized PCMs composites shows potential for improving efficiency of passive systems.

Summary: Polyphenols, bioactive compounds commonly found in plants, have high antioxidant power and are correlated to many health benefits. Traditional and novel extraction methods have been investigated for the extraction of polyphenols. The optimal extraction temperature for subcritical water extraction (SWE) can reach as high as 100-200 degrees C, leading to high yields and antioxidant capacities. The main factors affecting the extraction of polyphenols include thermal degradation, formation of Maillard reaction products, selection of plant matrix, and extraction conditions. The correlation between total phenolic content (TPC) and antioxidant activity lacks consensus.

Summary: The industrial sector consumes about 40% of global energy, and a significant amount of waste energy is discarded at low temperatures. Thermochemical heat transformers (THT) can recover this low-temperature waste heat by storing and releasing it at a higher temperature.
