Green Composites Based on Mater-Bi® and Solanum lycopersicum Plant Waste for 3D Printing Applications
2023
3D printability of green composites is currently experiencing a boost in importance and interest, envisaging a way to valorise agricultural waste, in order to obtain affordable fillers for the preparation of biodegradable polymer-based composites with reduced cost and environmental impact, without undermining processability and mechanical performance. In this work, an innovative green composite was prepared by combining a starch-based biodegradable polymer (Mater-Bi®, MB) and a filler obtained from the lignocellulosic waste coming from Solanum lycopersicum (i.e., tomato plant) harvesting. Different processing parameters and different filler amounts were investigated, and the obtained sample…
L'igiene sociale nel XIX e XX secolo. I lavatoi pubblici
2014
In the renewal of hygienic standards promoted by European Nations, many build-ings had to align themselves with the latest dictates of medical science and of "hy-gienist" engineers: one of these were the public laundries. The Exhibition of Hygiene clarified the objectives to be followed in the design: first of all, the laundries had to satisfy the needs of public health, preventing the spread of infectious germs and ensuring the health of the people, often subjected to serious influences for the infected garments and the moisture that they endured for most of the day; at the same time, these buildings had to create the decorum in the popular districts of the city and therefore they had to b…
Novel organo-modifier for thermally-stable polymer-layered silicate nanocomposites
2015
A new novel approach for the stabilisation of polymer-clay nanocomposites has been investigated based on reacting chemically an antioxidant function, a hindered phenol moiety, with an organic modifier based on a quaternary ammonium salt. The chemically linked antioxidant-containing organic modifier (AO-OM) was then introduced into natural montmorillonite (MMt) through a cation-exchange reaction resulting in antioxidant-containing organo-modified clay (AO-OM-MMt). The new antioxidant-containing modified clay, along with other organo-modified clays having a similar organo-modifier but without the reacted antioxidant, were characterised by spectroscopic, thermogravimetric and x-ray diffraction…
“I Have Karelia in My Soul” – Intra-action of Students, Seniors and Artefacts in a Community-Engaged Service-Learning Collaboration
2022
AbstractIn this chapter we examine a foreign language learning environment in a community-engaged setting in a Canadian city through a new materialist lens. As part of a service-learning project, Canadian students of Finnish language and culture visit a Finnish language seniors’ centre regularly to participate in different activities and spend time with the Finnish-speaking seniors. We examine the assemblage of the participants (seniors and students) and one artefact, a map, and offer a close analysis of the intra-action that takes place during one visit at the centre. In our analysis, our service-learning collaboration does not merely give a voice and agency to seniors. Rather, the seniors…
Ultrasensitive and highly specific detection of iodine ions using zirconium (IV)-enhanced oxidation
2022
Nuclear energy has significantly promoted the development of human society. However, nuclear pollution caused by nuclear accidents can lead to significant hazards to the environment and human health. As a major radioactive product, radioactive iodine (mainly existing as I−) detection has attracted significant attentions. In this study, zirconium(IV) is used to enhance the oxidation of environmental I− to form I2. Subsequently, the generated I2 oxidizes the chemical chromogenic substrate 3,3′,5,5′-tetramethylbenzidine, which is used for I− detection and realizes an ultralow limit of detection (LoD) of 0.176 nM. The LoD of our method, to the best of our knowledge, is the lowest among those of…
Comportamento al creep di biocompositi a base di PLA in presenza di irraggiamento UV
2018
Negli ultimi anni, l’interesse nei confronti dei biocompositi (spesso chiamati “compositi verdi”), realizzati con matrici polimeriche biodegradabili/compostabili e riempitivi organico-naturali ha conosciuto un livello crescente di interesse, sia da parte del mondo accademico che dell’industria. La letteratura fornisce numerose informazioni riguardo il comportamento di tali materiali (in particolare, riguardo il comportamento meccanico), ma di contro sono disponibili solo pochi dati riguardo il comportamento a creep [1] e, a nostra conoscenza, non sono disponibili studi sistematici riguardo il comportamento a creep sotto azione di raggi ultravioletti. Ci siamo quindi occupati di condurre uno…
Environmental citizenship in geography and beyond
2020
The need for wider action against environmental problems such as climate change has brought the debate about the role of citizen to the political, practical, and scientific domains. Environmental citizenship provides a useful tool to conceptualize the relation between citizenship and the environment. However, there exists considerable variation in the ways environmental citizenship is understood regarding both the aspect of citizenship and the relationship to the environment. In this article, we review the literature on environmental citizenship and investigate the evolution of the concept. The article is based on a literature search with an emphasis on geographical research. The concept of…

Technology in culture : a theoretical discourse on convergence in human-technology interaction
2014
Technology touches so many facets of contemporary life that one is not necessarily conscious any more of how and why it affects daily experience. Awareness of technology’s role often surfaces only when something goes wrong with a product. At that moment, people become aware of a misalignment between their ways of thinking, feeling and behaving, and the form/function of a product, presumably designed to make life easier. Equally ubiquitous and beyond daily awareness are cognitive, affective, and behavioural processes patterned by culture. It has been noted that cultural factors influence the perception and usage of technology. Understanding these processes is important to researchers, design…
