The addition of a photocatalyst to ordinary building materials such as concrete creates environmentally friendly materials by which air pollution or pollution of the surface can be diminished. The use of LiNbO3photocatalyst in concrete material would be more beneficial since it can produce artificial photosynthesis in concrete. In these research photoassisted solid-gas phases reduction of carbon dioxide (artificial photosynthesis) was performed using a photocatalyst, LiNbO3, coated on concrete surface under illumination of UV-visible or sunlight and showed that LiNbO3achieved high conversion of CO2into products despite the low levels of band-gap light available. The high reaction efficiency of LiNbO3is explained by its strong remnant polarization (70 µC/cm2), allowing a longer lifetime of photoinduced carriers as well as an alternative reaction pathway. Due to the ease of usage and good photocatalytic efficiency, the research work done showed its potential application in pollution prevention.

The exponential increase in textile cotton wastes generation and the ineffective processing mechanism to mitigate its environmental impact by developing functional materials with unique properties for geotechnical applications, wastewater, packaging, and biomedical engineering have become emerging global concerns among researchers. A comprehensive study of a processed cotton fibres isolation technique and their applications are highlighted in this review. Surface modification of cotton wastes fibre increases the adsorption of dyes and heavy metals removal from wastewater. Cotton wastes fibres have demonstrated high adsorption capacity for the removal of recalcitrant pollutants in wastewater. Cotton wastes fibres have found remarkable application in slope amendments, reinforcement of expansive soils and building materials, and a proven source for isolation of cellulose nanocrystals (CNCs). Several research work on the use of cotton waste for functional application rather than disposal has been done. However, no review study has discussed the potentials of cotton wastes from source (Micro-Nano) to application. This review critically analyses novel isolation techniques of CNC from cotton wastes with an in-depth study of a parameter variation effect on their yield. Different pretreatment techniques and efficiency were discussed. From the analysis, chemical pretreatment is considered the most efficient extraction of CNCs from cotton wastes. The pretreatment strategies can suffer variation in process conditions, resulting in distortion in the extracted cellulose’s crystallinity. Acid hydrolysis using sulfuric acid is the most used extraction process for cotton wastes-based CNC. A combined pretreatment process, such as sonication and hydrolysis, increases the crystallinity of cotton-based CNCs. The improvement of the reinforced matrix interface of textile fibres is required for improved packaging and biomedical applications for the sustainability of cotton-based CNCs.

This article presents the results of work done by the research group Science- Spirituality, whose third phase is called The Concept of Natural Harmony in Regards to the Man-nature Relationship: A Dialogue between Western and Eastern Cultures. This phase is an attempt to borrow from emerging Western epistemologies together with Far East traditions,<br />primarily the ancient Chinese Taoist tradition. Taking as a starting point the contemporary mankind crisis which has been proclaimed by philosophy, science and culture and regarding that which thinkers and scientists alike, such as Husserl and Prigogine have concluded, the limitations of modern-thinking are highlighted and a thorough revision of this thinking has been proposed. This revision must be done based on<br />the sense of humanity and on the dialogue between sciences and other cultures. In this case: Far Eastern culture.<br />This research work is built upon the idea of examining our perception concerning Taoist culture, assuming that this culture is reflected in its narratives and fables and that they offer an opportunity to gain new insights and meanings regarding the world and some of the issues faced by contemporary humankind. Thus, the category crisis becomes particularly<br />important since it is understood as a challenge or opportunity in an increasingly globalized and technology-oriented world marked by problems such as inequality, exclusion, paradoxes and the contradictions of the human being, including himself, others and furthermore a permanent critical relationship to nature from which he or she has been disconnected<br />in a physical, spiritual and energetic way (Guenon, 2010, 34).

Infrastructural developments are inevitable for the developing countries and hence the production of sustainable building materials is promoted worldwide. Sustainable development in the vicinity of tiles is bewildered for more than a decade. Production of conventional tiles such as cement concrete tiles, clay tiles and ceramic tiles is energy intensive approach and levies lot of strain over the adjunct ecosystem. On the other hand there are serious problems related to the disposal of flyash, Rice Husk Ash throughout the world. An approach has been taken to synthesis tiles based on these industrial byproducts as the base materials through Geopolymer technology. In this work, Geopolymer mortar after heat curing is applied as tiles. In this work, Flyash is replaced by Rice Husk Ash in various proportions such as 20, 40, 60, 80 and 100 percent. Tests such as workability, flatness, straightness, perpendicularity, water absorption, modulus of rupture and abrasion are conducted and fair results are obtained. This research also portrays the effect of Rise Husk Ash addition over the flyash based Geopolymer binder in the utility as tiles. The findings of this research work encourages the development of energy efficient tiles using industrial wastes. Keywords: Geopolymer, Rice Husk Ash, Tiles

Wood-based building materials meet the basic requirements of environmentally friendly construction, which is becoming increasingly important in the modern world. However, until recently, they were rarely used in high-rise construction in Russia. CLT became a revolutionary technology, it has proven itself in countries such as Switzerland, Norway, the U.S. and others. In Russia, it has not yet found widespread use, and CLT-panels are in demand only at the market of individual housing construction. Nevertheless, taking into account the positive foreign experience can be an example and become an incentive for more active implementation of modern environmentally friendly materials and technologies in Russia. The aim of the article is to study the possibilities of high-rise wooden house building in Russia based on world practice.

Gene expression programming (GEP) introduced by Candida Ferreira is a descendant of genetic algorithm (GA) and genetic programming (GP). It takes the advantage of both the optimization and search technique based on genetics and natural selection as GA and its programmatic Darwinian counterpart GP. It is gaining popularity because; it has to some extent eradicated the ‘cons' of both while keeping in the ‘pros'. It is still a new technique not much explored since its introduction in 2001. In this chapter both GA and GP is first discussed followed by the elaborate discussion of GEP. This is followed up by the discussion on research work done is different fields using GEP as a tool followed up by GEP architectures. Finally, here GEP has been used for detection of age from facial features as a soft computing based optimization problem using genetic operators.
