Environmentally friendly pathways towards the synthesis of vinyl-based oligocelluloses

Environmentally friendly methodologies of nanostructure synthesis.

Environmentally friendly synthetic methodologies have gradually been implemented as viable techniques in the synthesis of a range of nanostructures. In this work, we focus on the application of green-chemistry principles to the synthesis of complex metal oxide and fluoride nanostructures. In particular, we describe advances in the use of the molten-salt synthetic methods, hydrothermal protocols...

Environmentally Friendly Synthesis of Polymer-Grafted Nanoparticles

SYNTHESIS AND CHARACTERIZATION OF AN ENVIRONMENTALLY-FRIENDLY HYBRID NANOCOMPOSITE COATING

In this research, a kind of environmentally-friendly inorganic-organic hybrid nanocomposite coating based on silica containing titania/silica core/shell nanoparticles was synthesized and characterized for conservation of facade tiles in historical buildings. The matrix of the composite was prepared by sol-gel process via two methods of ultrasonic and reflux stirring. Tetraethyl orthosilicate (T...

An environmentally friendly approach to the synthesis of azo dyes based on 2-naphthol using kaolin-SO3H nanoparticles

Kaolin-SO3H nanoparticles were prepared via reaction of kaolin and chlorosulfonic acid and characterized by FT-IR, XRD, FESEM, TEM, XRF, EDS, BET and TGA. The activity of this green catalyst was probed by the synthesis of aryl diazonium salts as the starting reactant and then, their diazo coupling with  2-naphthol to form azo dyes in a solvent-free medium at room temperature...

An Environmentally Friendly Approach towards the Conservation of Vernacular Architecture

Contemporary theories of sustainability, concerning the natural and built environment, have recently introduced an environmental attitude towards the architectural design that, in turn, affects the practice of conservation and reuse of the existing building stock. This paper presents an environmentally friendly approach towards the conservation of vernacular architecture and it is based on the ...
