Radiative cooling paints offer a sustainable method for reducing energy demand in buildings. This work investigates the effects of particle volume concentration (PVC) calcium carbonate (CaCO3) and hollow silicon dioxide (SiO2) microparticles acrylic-based on capability. Paint solar reflectance increases as total PVC until peak is reached. The addition CaCO3 improves due to an enhancement near-i...

This paper describes the rapid fabrication of an organic/inorganic multi-layered composite film: Parylene-poly(vinyl alcohol) (PVA)-calcium carbonate (CaCO3) composite film. CaCO3 crystals on PVA film were sandwiched between Parylene films, and thermal bonding was carried out after folding the sandwiched crystals eight times. Using this method, a millimeterthick 48-layered organic/inorganic com...

polyamide-66(pa66)/caco3 micro- and nano-composites were prepared using a polymer solution method at filler loading of 0, 1, 2 and 3 weight percent. nano-size of caco3 was synthesized by micro-emulsion technique. the material was characterized by xrd, sem, ftir and uv-vis techniques. xrd results of composites suggested that caco3 particles are found in the amorphous phase of the semi-crystallin...

OBJECTIVES Despite the great contribution made by chemical substances to the development of modern civilization, their indiscriminate use has caused various kinds of damage to the global environment and human beings. Accordingly, the major developed countries and international society have tried to ensure the safe use of chemicals and a reduction in the use of hazardous chemicals through the es...

Introduction The research reported in this paper relates to an empirical study of business start-ups and their survival and growth or, conversely, their failure (exit) in the early years following start-up. A cohort of new start small or micro businesses which were set up with the support of a Training & Enterprise Council (TEC) in the West Yorkshire area are investigated. TECs are a government...
