Abstract

This Nutrients Special Issue focuses on neonatal nutritional advances for inflammatory disorders affecting infants such as necrotizing enterocolitis (NEC). Nutrition can significantly impact the development of certain diseases that afflict infants. This Special Issue aims to bring together the latest research on the role of nutrition in preventing or impacting neonatal disorders. Specifically, this Special Issue focuses on the role of breast milk or donor breast milk and the various components in milk that have been demonstrated to protect against NEC and other inflammatory diseases. This issue provides a comprehensive composite of the advances in nutritional strategies that can modulate or prevent neonatal intestinal disorders.

Abstract

Semi-solid metal (SSM) processing, as a viable alternative manufacturing route to those of conventional casting and forging, has not yet been fully exploited despite nearly half a century since its introduction to the metal industry. The slow pace of adopting SSM routes may be due to various reasons, including capital costs, profit margins, and, most importantly, the lack of detailed analysis of various SSM processes in open literature to confidently establish their advantages over more conventional routes. Therefore, the SSM community must disseminate their findings more effectively to generate increased confidence in SSM processes in the eyes of our industrial leaders. As such, we have embarked on the task to invite the leaders in SSM research to share their findings in a Special Issue dedicated to semi-solid processing of metals and composites. SSM processing takes advantage of both forming and shaping characteristics usually employed for liquid and solid materials. In the absence of shear forces, the semi-solid metal has similar characteristics to solids, i.e., easily transferred and shaped; by applying a defined force, the viscosity is reduced and the material flows like a liquid. These unique dual characteristics have made SSM routes attractive alternatives to conventional casting on an industrial scale. With the intention of taking full advantage of SSM characteristics, it is crucial to understand SSM processing, including topics such as solidification and structural evolution, flow behavior through modelling and rheology, new processes and process control, alloy development, and properties in general. This Special Issue focuses on the recent research and findings in the field with the aim of filling the gap between industry and academia, and to shed light on some of the fundamentals of science and technology of semi-solid processing.

Abstract

Thermoresponsive polymers, materials able to undergo sharp and often reversible phase separations in response to temperature stimuli, are introducing new paradigms in different fields, including medicine, advanced separations and oil and gas. In "Advances in Thermoresponsive Polymers", a clear picture of the frontiers reached in the understanding of the mechanistic behavior associated with temperature-induced phase separation, the influence of the polymer structure in regulating the macroscopic behavior of these materials and the latest applications for which thermoresponsive polymers show great potential is provided.

Abstract

Milk processing is one of the most ancient food technologies, dating back to around 6000 B.C. A huge number of milk products have been developed worldwide, representing a spectacular example of biodiversity and a priceless cultural heritage. After millennia of unanimous appreciation as a pillar of human nutrition, a series of questions about the desirability of their wide consumption have been raised. In the light of the growing threat deriving mostly from the spread of veganism and health consciousness, improving milk prcoessing safety and dairy nutritional characteristics, as well as deepening their functional characteristics, are of a primary exigency. This Special Issue contains several articles focusing on this hot topic, all of which add knowledge to the field and supply interesting ideas for developing new products and processes.
