The Chitosan Biomaterials: Advances and Challenges
No full text184 p.This Reprint gathers original research and reviews from the Special Issue “Chitosan Biomaterials: Advances and Challenges” (International Journal of Molecular Sciences), offering a clear picture of how chitosan is being developed into advanced, multifunctional biomaterials. The contributions highlight the versatility of chitosan, from films and scaffolds designed for controlled drug delivery and wound healing to membranes and tablets enriched with plant extracts that enhance antimicrobial performance. Studies also present smart composites that combine chitosan with innovative components such as boron-based molecules or cellulose nanofibers, improving strength, cytocompatibility, and therapeutic effect. Beyond biomedical use, chitosan is explored as a natural coagulant to improve drinking water quality and as a carrier for inhalable formulations with antiviral activity. Together, these works demonstrate how chemical modification and functionalization strategies expand the physicochemical and biological potential of chitosan. This Reprint provides an up-to-date and accessible resource for scientists, engineers, and practitioners interested in biomaterials, showing how a natural polymer can be transformed into solutions for medicine, healthcare, environmental protection, and beyond

Advanced Materials for Clinical Endodontic Applications
No full text144 p.During the last few decades, many new instruments and materials have been developed and introduced to the market. Along with these innovations, new, more clinically appealing, and promising techniques of root canal cleaning, shaping, and obturation were introduced to increase the success rates of endodontic treatment and retreatment, and the survival of endodontically treated teeth.
This Special Issue of the Journal of Functional Biomaterials will cover different topics of new biomaterials developed for endodontic application: materials for the disinfection/irrigation of the root canal system, temporary and permanent endoaccess and root canal filling, the management of endodontic complications, regenerative endodontics, or endodontic surgery
Incremental and Innovative Approaches to Professional Development for Mathematics Teachers
No full text220 p.Professional development researchers and teacher educators have been striving to improve mathematics instruction for decades, but in many places, there has been an inertia of procedurally focused mathematics instruction that has been incredibly resistant to change. Even when specific professional development (PD) efforts have found success in certain contexts or with certain teachers, it has proven difficult to sustain and disseminate these instructional improvements on a broader scale. This Special Issue on PD for mathematics teachers includes contributions reflecting on the limitations of transformational PD (PD that seeks profound changes in mathematics instruction) and studies on innovative and incremental approaches to PD striving to make instructional changes more manageable for teachers in their busy lives and complex educational contexts, and perhaps thus more likely to sustain and spread. Some of the featured research on incremental PD breaks down transformational practices into specific pieces, whereas other studies provide teachers with choices of smaller facets of teaching upon which to focus. Overall, this Special Issue urges the field to consider how incremental approaches to PD for mathematics teachers might address some of the limitations of typical transformational efforts
A Geoscience Perspective
No full textThis open access book on climate change assesses past climatic change from a geoscience perspective and directly and effectively addresses common misconceptions on climate and climate change.
A geoscience perspective on the multiple causes, rates, and consequences of climate change is essential context to assess modern climate change and our role in it, as well as forecasting future climate conditions. Yet, most textbooks on climate change focus only on the very recent past (e.g., last century), are not sufficiently engaging for non-scientists, or explore paleoclimate science at a level too challenging for introductory students. In addition, a wide range of misconceptions and confusion exists in the general public about climate change. Correcting misconceptions is an essential aspect of education, but educational research has shown that it is challenging to achieve. This textbook includes introductions to each thematic Part, that directly identify relevant misconceptions and refute them with clear, concise messages (i.e., learning goals) that are grounded in science and expanded on in the supporting chapters. Such refutation-style approaches have been shown to be effective at addressing misconceptions.
The book offers a clear trajectory of fundamental climate science concepts, which are most beneficially combined to provide a valuable geoscience perspective on the causes, rates, and consequences of climate change. It frames the collection of climate science chapters with impactful, relevant social science context: starting the book with a chapter that explores the reasons behind the disconnect between the scientific and public understanding of climate change, and ending the book with a discussion of the intersection of ethics and climate change. Short topical expansions or excursions are included as “boxes” within selected chapters.
This book will serve as a basic resource for learning about the lessons that the paleoclimate record offers to evaluate the seriousness of modern and future climate change
Public–Private Partnerships (PPPs) for Construction Project Deliveries
Full text link438 p.Public–Private Partnerships (PPPs) are central to modern infrastructure development, enabling governments to harness private sector finance and expertise for complex construction projects. Their success, however, depends on managing risks, stakeholder alignment, financial viability, and sustainability. This reprint compiles eighteen peer-reviewed papers from a Special Issue of the journal Buildings, curated by Dr. Patrick S.W. Fong, offering global insights into the mechanisms, challenges, and success factors shaping PPPs. Topics include the historical evolution of PPP research, policy dynamics (e.g., China), project initiation and planning (e.g., business case development in China and New Zealand, project briefing in mature markets, success factors in the UAE, and competency models), risk management (e.g., assessment systems for transport, qualitative tools like ‘Riesgo’, risks in Iran’s water sector, and sustainable outcomes), and performance drivers (e.g., trust, incentives in rail transit, success factors in water and power sectors, and concession period drivers in healthcare). It also explores contextual applications such as urban regeneration (Italy) and community resilience. Covering regions from Asia to Europe and the Middle East, and sectors from transport to utilities and health, this volume delivers a comprehensive, evidence-based understanding of PPPs for academics, policymakers, practitioners, and students navigating the complexities of infrastructure delivery through public–private collaboration

Liver Fibrosis: Mechanisms, Targets, Assessment and Treatment
No full text228 p.Fibrosis is a double-edged sword. On one hand, it can be the final stage of healed inflammation as scar tissue. On the other hand, it is often linked to a decrease in organ function or complete organ failure. Additionally, in liver disease, fibrosis serves as an indicator of disease progression towards liver cirrhosis or hepatocellular carcinoma. This is particularly true for non-alcoholic fatty liver disease, a widespread disorder associated with Western lifestyles and diets. To interfere with organ fibrosis, it is crucial to have a better understanding of its initiation, perpetuation, and resolution at the molecular level. The development of liver fibrosis can be caused by metabolic factors (such as alcohol, diet, and drugs), infections (such as viruses), autoimmune conditions (like primary biliary cholangitis), or genetic abnormalities (such as increased iron storage). The molecular pathways that lead to advanced fibrosis vary depending on the underlying cause. The goal of this Special Issue is to dissect these processes and provide more clarity on the subject
