Summary: Excessive urban construction driven by uncontrolled population growth has serious consequences for the environment and human life. Sustainable construction materials and technologies have been found to be more energy and cost efficient. Agricultural waste and insulating materials are examples of sustainable materials used in climate change mitigation. The use of pomegranate peel waste in fired clay bricks has been found to reduce energy consumption and carbon dioxide emissions. Additionally, the economic feasibility of these bricks has been evaluated, and they are considered a feasible building material due to their ability to decrease heat gain and preserve energy.

Summary: In this paper, a biodegradable nanocomposite foam with outstanding electromagnetic interference shielding was fabricated by blending poly (butylene succinate) (PBS) with carbon nanotubes (CNTs) followed by foaming with supercritical CO2. The addition of CNTs significantly improved the crystallization temperature and melting temperature of PBS nanocomposites, as well as enhanced the electrical properties. The CNTs also endowed the PBS foam with adjustable electromagnetic interference (EMI) shielding property.

Summary: Copper ferrite (CuFe2O4), zinc oxide (ZnO), and the zinc oxide-copper ferrite binary composite were prepared using wet chemical precipitation method. A ternary composite (ZnO-CuFe2O4/CNTs) was also prepared using ultrasonic treatment method for photocatalytic degradation of chemical pollutants. XRD, UV-visible spectroscopy, SEM, and FT-IR were used to analyze the fabricated catalysts. The photocatalytic performance of the prepared samples was observed under sunlight, with 61% benzoic acid and 82% congo red being degraded in 120 min. The ZnO-CuFe2O4/CNT ternary NC showed superior photocatalytic efficiency compared to pure ZnO and CuFe2O4. Hydroxyl radicals were found to be the main species responsible for the photocatalytic degradation of organic contaminants.

Summary: This paper experimentally evaluated the radiation shielding properties of ball clays produced with different percentages of micro and nano ZnO. The results showed that ball clay with nano ZnO had a higher linear attenuation coefficient (LAC) and a slightly lower half-value layer (HVL) compared to ball clay with micro ZnO. This suggests that ball clay with nano ZnO is more effective in attenuating radiation in limited spaces.
