Smart polymers react sharply to small changes in physical or chemical conditions and present an intelligent response to chemical stimuli (i.e., chemical species -including biomolecules-, pH, solvents, redox, stimuli that trigger controlled depolymerization) and physical stimuli (i.e., temperature, light, mechanical stress and electrical stimuli). For these reasons, the interest in smart polymers has recently increased exponentially, especially in biological stimuli (i.e., application of polymer-based biosensors, drug delivery, tissue engineering, precision medicine and cell therapy). This book offers a unique opportunity to review the physical-chemical fundamentals of smart polymers, and their behaviour.

While plastics offer undeniable benefits, their exponential growth in production has raised concerns about resource depletion and pollution. Efforts to address the end-of-life challenges of plastics have been hindered by low recycling rates and inadequate waste management systems. Only a fraction of plastic waste is recycled globally, with a significant portion ending up in landfills or polluting natural environments. The persistence of plastic waste, coupled with its widespread contamination of oceans, freshwater systems, and terrestrial habitats, underscores the urgent need for solutions to mitigate its environmental impact. In response to these challenges, emerging circular plastics technologies, particularly chemical recycling, offer promising avenues for transforming plastic waste into valuable resources. Chemical recycling methods, including pyrolysis, depolymerization, and open-loop recycling, present opportunities to break down plastics into fuels, chemicals, and monomers, thus closing the loop on plastic production and consumption. This book provides an overview of emerging chemical recycling technologies, focusing on advancements in pyrolysis, depolymerization, and open-loop recycling processes. Highlighting notable technological innovations and industry efforts to commercialize these methods, the book serves as a guide to understanding the potential of chemical recycling in addressing the plastic waste crisis.

Almost 50 years have passed since the famous papers of Hugo Rietveld from the late sixties where he describes a method for the refinement of crystal structures from neutron powder diffraction data. Soon after, the potential of the method for laboratory X-ray powder diffraction was discovered. Although the method is now widely accepted, there are still many pitfalls in the theoretical understanding and in practical daily use. This book closes the gap with a theoretical introduction for each chapter followed by a practical approach. The flexible macro type language of the Topas Rietveld software can be considered as the defacto standard.

The present book is an introduction to the philosophy of mathematics. It asks philosophical questions concerning fundamental concepts, constructions and methods - this is done from the standpoint of mathematical research and teaching. It looks for answers both in mathematics and in the philosophy of mathematics from their beginnings till today. The reference point of the considerations is the introducing of the reals in the 19th century that marked an epochal turn in the foundations of mathematics. In the book problems connected with the concept of a number, with the infinity, the continuum and the infinitely small, with the applicability of mathematics as well as with sets, logic, provability and truth and with the axiomatic approach to mathematics are considered. In Chapter 6 the meaning of infinitesimals to mathematics and to the elements of analysis is presented. The authors of the present book are mathematicians. Their aim is to introduce mathematicians and teachers of mathematics as well as students into the philosophy of mathematics. The book is suitable also for professional philosophers as well as for students of philosophy, just because it approaches philosophy from the side of mathematics. The knowledge of mathematics needed to understand the text is elementary. Reports on historical conceptions. Thinking about today‘s mathematical doing and thinking. Recent developments. Based on the third, revised German edition. For mathematicians - students, teachers, researchers and lecturers - and readersinterested in mathematics and philosophy. 　 Contents On the way to the reals On the history of the philosophy of mathematics On fundamental questions of the philosophy of mathematics Sets and set theories Axiomatic approach and logic Thinking and calculating infinitesimally – First nonstandard steps Retrospection
