Experimentation of innovative green materials for the conservation and restoration of Cultural Heritage [Sperimentazione di materiali innovativi green per la conservazione e il restauro dei Beni Culturali]
Questo studio indaga lo sviluppo e l'applicazione di materiali attivati alcalinamente (AAMs) derivati da rifiuti industriali per la conservazione e il restauro del Patrimonio Culturale. Gli AAMs, sintetizzati da materie prime aluminosilicatiche e soluzioni alcaline, offrono vantaggi come la …

High-volume recycled materials for sustainable transportation infrastructure
… concrete made with high-volume of recycled materials in transportation infrastructure. The main focus was to develop mixtures for rigid pavement construction. A variety of fine and coarse recycled concrete aggregates (RCA) were investigated. The feasibility of replacing 50% of Portland …

Applications of Geopolymer in Civil Engineering: Feasibility Study of Loess Stabilization and Waste Concrete Recycling
… is being produced every year. This means that green materials and recycling the C&D waste are of great significance to the civil engineers for the sustainable development. Geopolymer, which is an inorganic material formed by alkaline activation of aluminia- and silica-containing material …

A reevaluation of distortional isomerism.
The blue and green forms of MoOCl₂(PMe₂Ph)₃ and [LWOCl₂]PF₆ (L = 1,4,7-trimethyltriazacyclononane) are not examples of distortional isomerism. For both systems, the blue form is pure and the green form is a mixture of the blue complex and other components. Characterizations of the green material of …

Functional Protein Based Materials
… for use in biocomposites and soft actuating materials, respectively. In Chapter II, the self-assembly mechanism of trypsin hydrolyzed wheat gluten (THWG) into rigid β-sheets was applied to an aqueous polyvinyl alcohol (PVA) environment. Aqueous PVA was used in order to determine the effects …

A Colorful Past: Turquoise and Social Identity in the Late Prehispanic Western Pueblo Region, A.D. 1275–1400
… groups in particular, turquoise and other blue-green minerals hold a prominent place in myth, ritual, aesthetics, and cosmology. They continue to be used as important offerings, deposited in shrines and decorating objects like prayer-sticks and adornments. Archaeological occurrences of turquoise …

Production and characterisation of hydroxyapatite/multi-walled carbon nanotube composites
… (CNTs), as one of the strongest and stiffest materials available, have the potential to strengthen and toughen HA, thus expanding the range of clinical uses for the material. Furthermore, studies have suggested that the nanotubes themselves possess some bioactive properties. This work sought …

Emissions of Phthalate Plasticizer from Polymeric Building Materials
… organic compounds (SVOCs) from polymeric materials and their subsequent interaction with indoor surfaces and airborne particles was developed. The emissions model is consistent with analogous mechanistic models that predict emission of volatile organic compounds (VOCs) from building …

Advancing the technology development for better quality wood plastic composites: process ability study
Wood Plastic Composites (WPC) have advantages over natural wood such as improved stiffness, recyclability, and waste minimization. However, issues such as the difficulty of processing WPC with conventional methods, volatile emission from the wood and the composites’ lack of strength must be …
