Bibliometric insights into the spectroscopy research field: A food science and technology case study

2019

The food industry is in need of analytical solutions to maintain high quality and safety standards during the entire food production chain. Spectroscopy applications are targeted as a major solution due to its cost-effective, simple, efficient and multiparametric nature. Bibliometric studies provide a critical evaluation of the status of a research topic through the quantification of measurable outcomes of research activity. The main aim of this study was to use a bibliometric approach to the evaluation of the current status of the spectroscopy research applied to food science and technology. The critical evaluation of the results showed the most commonly used spectroscopy applications as w…

Benzodiazines: recent synthetic advances.

2017

Benzodiazines (diazonaphthalenes with both nitrogens in the same ring) – cinnolines (1,2-benzodiazine), quinazolines (1,3-benzodiazine), phthalazines (2,3-benzodiazine) and quinoxalines (1,4-benzodiazine) – are important class of compounds with broad biological properties and wide application in pharmaceutical as well as agrochemical arenas. These diazaheterocycles are present in a wide variety of bioactive natural products as well as synthetic molecules that are good drug candidates constituting key structural units responsible for their pronounced therapeutic activities. Their rapidly growing uses and applications in medicinal and agrochemical arenas prompt the researchers for further stu…

Advances in Research for Biomimetic Materials

2018

Smart surfaces and materials can play a significant role in intelligent, adaptive and responsive envelopes because of these intrinsic properties. The environmental question and energy efficiency in which the construction sector is involved, is in a process that can not be interrupted and that puts researchers and designers in front of a scientific and design challenge in which it is necessary to contribute to find different ways of study and experimentation on new materials and constructive languages, ranging from the application, to the structural, design and molecular, to mention the main ones. The development of technologies is helping architects of the “biomimetic current” to recreate c…

Thermodynamics, transport phenomena, and electrochemistry of external field-assisted nonthermal food technologies

2017

Interest in the development and adoption of nonthermal technologies is burgeoning within the food and bioprocess industry, the associated research community, and among the consumers. This is evident from not only the success of some innovative nonthermal technologies at industrial scale, but also from the increasing number of publications dealing with these topics, a growing demand for foods processed by nonthermal technologies and use of natural ingredients. A notable feature of the nonthermal technologies such as cold plasma, electrohydrodynamic processing, pulsed electric fields, and ultrasound is the involvement of external fields, either electric or sound. Therefore, it merits to study…

Monolithic integration of GMR sensors for standard CMOS-IC current sensing

2017

Abstract In this work we report on the development of Giant Magnetoresistive (GMR) sensors for off-line current measurements in standard integrated circuits. An ASIC has been specifically designed and fabricated in the well-known AMS-0.35 μm CMOS technology, including the electronic circuitry for sensor interfacing. It implements an oscillating circuit performing a voltage-to-frequency conversion. Subsequently, a fully CMOS-compatible low temperature post-process has been applied for depositing the GMR sensing devices in a full-bridge configuration onto the buried current straps. Sensitivity and resolution of these sensors have been investigated achieving experimental results that show a de…

Hydrogen Production from Sea Wave for Alternative Energy Vehicles for Public Transport in Trapani (Italy)

2016

The coupling of renewable energy and hydrogen technologies represents in the mid-term a very interesting way to match the tasks of increasing the reliable exploitation of wind and sea wave energy and introducing clean technologies in the transportation sector. This paper presents two different feasibility studies: the first proposes two plants based on wind and sea wave resource for the production, storage and distribution of hydrogen for public transportation facilities in the West Sicily; the second applies the same approach to Pantelleria (a smaller island), including also some indications about solar resource. In both cases, all buses will be equipped with fuel-cells. A first economic a…

The Desalination Process Driven by Wave Energy: A Challenge for the Future

2016

The correlation between water and energy is currently the focus of several investigations. In particular, desalination is a technological process characterized by high energy consumption; nevertheless, desalination represents the only practicable solution in several areas, where the availability of fresh water is limited but brackish water or seawater are present. These natural resources (energy and water) are essential for each other; energy system conversion needs water, and electrical energy is necessary for water treatment or transport. Several interesting aspects include the study of saline desalination as an answer to freshwater needs and the application of renewable energy (RE) devic…

Sustainability of the Renewable Energy Extraction Close to the Mediterranean Islands

2017

The aim of this work is to explore the possibility of transitioning a fuel powered island to a renewable powered one. This transition is analyzed for the real MV/LV distribution system of the island of Pantelleria, in the Mediterranean Sea. Particularly, this work is focused on a renewable source nowadays totally unused: wave energy. Thanks to the innovative generator prototype designed by Department of Energy of University of Palermo (Italy), wave energy is able to represent a primary source for the production of electric energy in the Mediterranean islands. The procedures applied in the present article, as well as the main equations used, are the result of previous applications made in di…
