Advanced energetics of a Multiple-Effects-Evaporation (MEE) desalination plant. Part II: Potential of the cost formation process and prospects for en…
2010
This paper represents the 2nd part of a paper in two parts. In part I a 2nd Principle analysis of a Multiple- Effects-Evaporation (MEE) process has been proposed. In this Part II perspectives for process improvement will be investigated, along two distinct research lines: the thermoeconomics-aided optimization of a new system and the increase of thermal efficiency for existing systems by a pinch-based plant retrofit. As concerns the first research line, a detailed productive structure for the plant stage (i.e. effect) examined in Part I is presented; the cost formation structure is then used to improve a simplified optimization process, revealing capable to properly reflect the interactions…

A review of emerging trends in membrane science and technology for sustainable water treatment
2020
Abstract Access to clean or potable water will continue to be a global challenge in as much as sustainable solutions are far-fetched. It has become imperative to improve the efficiency of conventional membrane science and technologies for water treatment in order to reduce their deleterious impact on the environment. Some sustainability solutions have been proposed and studied in recent years. Therefore, a critical and comprehensive review of emerging trends in sustainable membrane-based desalination and wastewater treatment is presented in this paper. Some of the emerging trends in membrane science and technology for sustainable water treatment include the reuse of membranes, reuse of wast…
Nexus Water & Energy: A Case Study of Wave Energy Converters (WECs) to Desalination Applications in Sicily
2016
The recent studies about interactions among energy and water are considered as a new field of research. As almost all energy generation processes require significant amounts of water, and water requires energy for treatment and transport, so these two resources are inextricably linked. The main aim of this work is a presentation of the use of renewable energy for desalination plants in Sicily: in particular exploitation of wave energy into electrical energy necessary for water treatment. Desalination is the most energy intensive water treatment technology but it could be solution for many problems in water supply for areas with chronic debt of water. In this study we find three section: in …
Solar radiation as a prospective energy source for green and economic processes in the food industry: From waste biomass valorization to dehydration,…
2019
International audience; Solar energy has recently attracted the attention of both industry and academia, to be used as a source of clean energy for green production of various products such as food-related commodities. This review aims to explore the applicability of this green energy source for extraction of valuable components (e.g., bioactive compounds and essential oils) from plant materials and waste biomass, dehydration of plant materials, water recovery through desalination, decontamination, cooking, and baking of agri-food products. According to the literature, concentrated solar power systems (CSP) have been successfully employed for bioactive compounds (e.g. essential oils) extrac…
Preparation of novel high permeability and antifouling polysulfone-vanillin membrane
2020
International audience; A novel high-performance nanofiltration membrane was fabricated by a simple and scalable route involving in situ cross-linking of hydrophilic, cheap, and environmentally friendly vanillin as antifouling agent with polysulfone (PSf) for salt rejection performance. Vanillin acts as a porogen, which induces a negative surface charge on the membrane surface due to the presence of polar functional groups like alcohol and aldehyde. The surface properties, including charge, morphology, and hydrophilicity, were investigated in detail using analytical instruments. The nanofiltration performance of the fabricated PSf-vanillin membranes was dependent on the percentage of vanill…
Calcium binding and ionic conduction in single conical nanopores with polyacid chains: model and experiments.
2012
Calcium binding to fixed charge groups confined over nanoscale regions is relevant to ion equilibrium and transport in the ionic channels of the cell membranes and artificial nanopores. We present an experimental and theoretical description of the dissociation equilibrium and transport in a single conical nanopore functionalized with pH-sensitive carboxylic acid groups and phosphonic acid chains. Different phenomena are simultaneously present in this basic problem of physical and biophysical chemistry: (i) the divalent nature of the phosphonic acid groups fixed to the pore walls and the influence of the pH and calcium on the reversible dissociation equilibrium of these groups; (ii) the asym…
HSP10,HSP70 AND HSP90 IMMUNOHISTOCHEMICAL LEVELS CHANGE IN ULCERATIVE COLITIS AFTER THERAPY
2011
Ulcerative colitis (UC) is a form of inflammatory bowel disease (IBD) characterized by damage of large bowel mucosa and frequent extra-intestinal autoimmune comorbidities. The role played in IBD pathogenesis by molecular chaperones known to interact with components of the immune system involved in inflammation is unclear. We previously demonstrated that mucosal Hsp60 decreases in UC patients treated with conventional therapies (mesalazine, probiotics), suggesting that this chaperonin could be a reliable biomarker useful for monitoring response to treatment, and that it might play a role in pathogenesis. In the present work we investigated three other heat shock protein/molecular chaperones:…
Riflessioni e traiettorie di ricerca interdisciplinari sulla transizione digitale
2022
The contribution introduces the topic covered by vol. 12 of AGATHÓN through essays, studies, research and projects on Innovability©® | Digital Transition to investigate the current widespread transformation that unites dichotomies (analogue and digital), enhances oxymorons (artificial intelligence), creates paradoxes (materiality of the intangible), while indiscriminately involving architecture, humanities and social sciences, anthropology, sociology, ecology, biology, physical-mathematical sciences and neurosciences, with impacts that – while already visible today and accelerated in part by the extraordinary global health emergency – will become even more evident in the medium and long ter…
