Performance of Earth Bricks Supplemented by Nanoparticles and their Application in Architecture
2017
The potential for architecture offered by natural materials in terms of comfort, reduction of embodied energy and energy-saving in the operational phase, dictates in-depth research that might highlight advantages and contribute to improving their characteristics. This research focuses on earth bricks and, in particular, a type of brick made from unfired clay, known as adobe. The aim of the research is to verify improvements in performance of adobe with the aid of nanotechnology. The adobe mixture was prepared with water, soil (from Sicily) and LAPONITE® as a stabilizer. The adobe bricks were subjected to tests of resistance to compression and flexion, resistance to abrasion, capillary absor…
Characterization of the ESR response of alanine dosimeters to low-energy (1-40 keV) X-rays
2016
The aminoacid L-a-alanine has attracted considerable interest for use in radiation ESR dosimetry and has been formally accepted as a secondary standard for high-dose (kGy) and transfer dosimetry . The accuracy of the method is quite high, largely due to the low dependence of the alanine response on various irradiation parameters (photon energies above 100 keV, dose rate, temperature, etc.). Furthermore, this system presents alinear response to dose, fairly high sensitivity, tissue equivalence, absence of fading, small dimensions, ruggedn ess, and non-destructive readout. In this work, we examined the energy dependence of alanine ESR dosimeters in the low energy X-photon energy range between…
Sustainable and cost-efficient energy supply and utilisation through innovative concepts and technologies at regional, urban and single-user scales
2019
Abstract The environmental impact of the energy sector and the security and economics of energy supply and utilisation have been raising increasing concerns, stimulating the search for innovative solutions for a sustainable use of resources. This article provides an overview of published research in this area, with a focus on papers contributed in special issues of leading journals dedicated to the series of Conferences on Sustainable Development of Energy, Water and Environment Systems (SDEWES), including the articles in the current special issue. Based on this review, research trends are identified and achievements supporting the energy transition are highlighted. The studies that focused…
