We are delighted to present the 2023 Women in Chemistry article collection. Following the celebration of International Women’s Day 2023 and the UNESCO International Day of Women and Girls in Science, Frontiers in Chemistry is proud to offer this platform to promote the work of women in this field. At present, less than 30% of researchers worldwide are women. Long-standing biases and gender stereotypes are discouraging women and girls away from science-related fields, and STEM research in particular. Science and gender equality are, however, essential to ensure sustainable development as highlighted by UNESCO. In order to change traditional mindsets, gender equality must be promoted, stereotypes defeated, and girls and women should be encouraged to pursue STEM careers.
Elasticity is absolutely necessary for living a normal life. This fact is cruelly revealed when respiratory, cardiac, digestive, sensory, motor, reproductive or aesthetic problems appear following the inexorable decline of our elastic capital. The protection and maintenance of this capital is one of life’s priorities since this declination begins at the age of twenty and accelerates in times of crises and pandemics. However, there are no therapies yet designed to remedy it. The first part of the book explains the consequences surrounding a lack of elasticity in the skin, the most visible decline, and then other defects in elasticity throughout our bodies, exploring places rarely mentioned. The second part describes the research fighting against elasticity anomalies and examines useful behaviors to protect our elastic capital (e.g. our diets and physical and cognitive activities). This last point is at the heart of current social debates on nutritional, behavioral, environmental and even ethical levels.
Advances in nanotechnology are leading to the creation of composites with a myriad of medical applications. This forward-thinking book melds research in biocomposites with advances in nanocomposite technology to provide an interdisciplinary resource on advanced materials for the biomedical industry. It brings together pioneering researchers who describe their contributions to the field. Among other areas, they cover nanostructured polymer composites and nano/bio composites. They look at developments in tissue engineering, safer resins for tooth and bone repair, and improved artificial joints. They also discuss potential opportunities for continued research in this well-funded field.
L’élasticité est absolument nécessaire pour vivre une vie normale. Ce fait se révèle cruellement lorsque des problèmes physiques, respiratoires, cardiaques, digestifs, sensoriels, moteurs, reproductifs ou esthétiques apparaissent à la suite de l’inexorable déclin de notre capital élastique. Cette déclinaison commence à la fin de la croissance et s’accélère en temps de crise (et de pandémie). La protection et l’entretien de ce capital est donc une des priorités de la vie. Cependant, il n’existe pas encore de thérapie conçue pour y remédier. L’élasticité du vivant définit tout d’abord les conséquences dérivant d’un manque d’élasticité de la peau – le déclin le plus visible, puis d’autres défauts d’élasticité dans notre corps, souvent insoupçonnés et rarement mentionnés. Cet ouvrage présente ensuite les recherches luttant contre les anomalies d’élasticité et examine les comportements utiles pour protéger notre capital élastique (alimentation, activités physiques et cognitives, etc.). Ce dernier point est au coeur des débats de société actuels sur les plans nutritionnel, comportemental, environnemental, voir éthique.
Quello che gli autori si sono proposti è mostrare l’importanza che la chimica ha avuto in “Civiltà delle Macchine” e il modo in cui Sinisgalli ha affrontato questo tema, lontano dalla sua cultura originaria di “matematico” e ingegnere. I curatori non si sono limitati a raccogliere gli articoli che trattavano specificatamente di un argomento “chimico”per non tradire lo spirito di Sinisgalli. Era necessario esaminare nel suo complesso il modo in cui Sinisgalli aveva trattato l’intera tematica, in tutte le sfaccettature. Egli invitava a mischiare le culture, a contaminare la cultura scientifica e quella umanistica: per fare questo non ci si è limitati a considerare articoli s...
This book was originally published in 2002. Elastic proteins occur in a wide range of biological systems where they have evolved to fulfil precise biological roles. The best known include proteins in vertebrate muscles and connective tissues, such as titin, elastin and fibrillin, and spider silks. However, other examples include byssus and abductin from bivalve molluscs, resilin from arthropods and gluten from wheat. Interest in elastomeric proteins has been high for several reasons. Firstly, their biological and medical significance, particularly in human disease. Secondly, the unusual properties of proteins such as spider silks provide opportunities to develop materials. Thirdly, the development of scanning probe microscopy makes it possible to study structures and biomechanical properties of these proteins at the single molecule level. This book will be of value to anyone with an interest in the various aspects of elastomeric proteins.
Italians to America provides both genealogists and researchers of family history with the first extensive, indexed source of Italian surname immigrants. This entire project was planned to span the years 1850 through 1893, but now the series has been extended. The series reproduces information from the original passenger lists filed by all vessels entering U.S. ports from abroad. Ships that departed from Italian ports or carried passengers who declared themselves to be of Italian origin are included, with first and last names, age, sex, occupation, and province and village of origin (whenever available) provided for each emigrant. A complete index of names is included at the end of every volume. Italians to America may be ordered by individual volume. Standing orders, which receive a 10% discount, are also welcomed.
