“…Nanomaterials are gaining widespread importance due to their key characteristics and applications in diverse fields such as agriculture [1,2,3], energy [4,5], electronics [6,7], catalysis [8,9], pharmaceuticals [10,11], engineering [12,13], technology [14,15] or the food industry [16,17]. The reduced size of nanomaterials affects their fundamental characteristics, altering the corresponding physical, chemical and biological behaviours.…”

The application of nanomaterials in the construction field is allowing the development of smart, green, durable and more efficient buildings. Among the most widely researched nanomaterials are nano-sized cool pigments, which are being enforced to achieve thermal and energy efficient façades, with the development of high reflectance and retroreflectance coatings. Their peculiar optical and catalytic activity turns nanomaterials into suitable candidates to be use as dark coloured high solar reflectance without affecting aesthetic characteristics, thus improving the durability of coatings. The objective of this paper is to review the state-of-the-art on the benefits of using high reflectance nano pigments as coatings in building façades and their production and synthesis processes. It is thus divided into three main topics: (i) the benefits of using nanopigments on façades, (ii) the most important nanomaterials used as cool pigments and (iii) the main methods of synthesising nanopigments. One expects that the study of near-infrared nanopigmentation synthesis processes will be able to promote and disseminate the use of nanotechnology in construction, assessing the production problems and limitation and thus helping to disseminate new products by reducing production costs and increase availability.

Abstract:The aim of this paper is to present characteristics, toxicity and environmental behavior of nanoparticles (NPs) (silver, copper, gold, zinc oxide, titanium dioxide, iron oxide) that most frequently occur in consumer products. In addition, NPs are addressed as the new aquatic environmental pollutant of the 21 st century. NPs are adsorbed onto particles in the aquatic systems (clay minerals, fulvic and humic acids), or they can adsorb environmental pollutants (heavy metal ions, organic compounds). Nanosilver (nAg) is released from consumer products into the aquatic environment. It can threaten aquatic organisms with high toxicity. Interestingly, copper nanoparticles (Cu-NPs) demonstrate higher toxicity to bacteria and aquatic microorganisms than those of nanosilver nAg. Their small size and reactivity can cause penetration into the tissues and interfere with the metabolic systems of living organisms and bacterial biogeochemical cycles. The behavior of NPs is not fully recognized. Nevertheless, it is known that NPs can agglomerate, bind with ions (chlorides, sulphates, phosphates) or organic compounds. They can also be bound or immobilized by slurry. The NPs behavior depends on process conditions, i.e. pH, ionic strength, temperature and presence of other chemical compounds. It is unknown how NPs behave in the aquatic environment. Therefore, the research on this problem should be carried out under different process conditions. As for the toxicity, it is important to understand where the differences in the research results come from. As NPs have an impact on not only aquatic organisms but also human health and life, it is necessary to recognize their toxic doses and know standards/regulations that determine the permissible concentrations of NPs in the environment.Unauthenticated Download Date | 5/12/18 7:36 AM

“…In addition, they possess high chemical and thermal stability and could be chemically modified with functional groups for the covalent binding of molecules [2]. Although pore size is recognized as the main parameter for enzyme immobilization [12], the efficiency of the process is also driven by other factors like the chemical interactions between the selected support and the enzyme [13], the area and pore filling capacity of the selected material [14], the ionic strength present in the immobilization media, the acidity or alkalinity present in the surface of the support [15], which also affects the orientation of the enzyme inside the pore [16]. During immobilization, enzymes may undergo some conformational changes by the mere fact of being confined inside a cavity, resulting in the modification of their tridimensional structure and activity http://dx.doi.org/10.1016/j.molcatb.2015.02.004 1381-1177/© 2015 Elsevier B.V.
