Modules Teaching inclusive and critical searching

This publications presents two modules, one for lecturers and one for students, on inclusive teaching and critical searching. The modules highlight how search engines and databases are far from neutral. They provide handles to critically engage with the information found on these platforms and how to pass this information on to your students. The modules can be used as an extension to information literacy courses or guides. Besides general information, the modules contain VU specific information. This information can be adjusted to other contexts.

A Novel Approach to Artificial Fracture Pattern Generation

In this recorded presentation from glasstec 2024, Leon Bohmann, from TU Darmstadt, focuses on the problem of spontaneously broken glass, specifically how it fractures into numerous fragments, a process which is not yet fully understood and currently requires expensive physical testing for safety validation. The speaker proposes a numerical simulation approach to predict these fracture patterns. By analyzing over 130 experiments, key data on fragment orientation and intensity relative to the impact point was gathered. The simulation method involves randomly distributing points based on this data, placing ellipses on them, and then using a watershed algorithm to generate realistic fracture patterns. The results show a promising visual and statistical match to actual broken glass, offering a potential alternative to costly physical tests.

Fracture Mechanics Fundamentals

In this video, Daniel Trias Mansilla explains the core principles of fracture mechanics, which provides an alternative to traditional stress analysis by accounting for the inherent cracks and defects in real materials. The field introduces two main criteria for predicting failure. The first is an energy-based approach, using the energy release rate (G), which measures the energy available to propagate a crack. The second is a stress-based approach, using the stress intensity factor (K), which characterizes the intense stress field near a crack tip. Fracture occurs when either of these values reaches a critical threshold (Gc or Kc), which are material properties known as fracture toughness. These concepts allow engineers to predict failure in flawed components more accurately than traditional methods. The video was produced by the Open GLASSroom project.

Faces of Open Science workshop

Drawing on Utrecht University's Faces of Open Science project, we’ve developed a set of ready-to-use educational activities that invite participants to explore the rich diversity of perspectives within the open science movement. These engaging, interactive materials help learners reflect on their own views, values, and roles in shaping open science—making abstract principles tangible, personal, and actionable. The materials can be used in full as a 4-hour workshop or can be split up in separate activities that take between 30 and 60 minutes. Activities are all developed to promote interaction between participants, for example by storytelling, crafting, or debating.

Transitioning towards a circular (healthcare) economy - BOOK

This book offers a comprehensive roadmap toward a circular and sustainable healthcare system, structured into three distinct parts. Part I describes circular principles and policy tactics. Chapter 1 outlines the essentials of sustainable healthcare and designates the paradox in daily practice of sustainability and the circular economy. In Chapter 2 the impact of leadership on policy together with best practices is discussed. The legislation and infrastructural web, in which many stakeholders and circular economy initiatives are strangled, is described. Despite the fact that politicians and policymakers are motivated to encourage sustainability, the infrastructure is designed to discourage circular economy projects. This chapter shows examples of setting-up intrinsic motivated teams of hospital staff, green teams, industry leaders and scientific motivated research teams. Swimming against the current is about the legislation paradox. In chapter 3 described as how legislation should be redesigned to accomplish the goals as set out in the green deal and the climate law. Part II serves as a practical guide to implementing circular strategies. In chapter 4 the reader is guided through the fundamentals of circular strategies by visualizing the circular economy. Chapter 5 reveals successful design strategies for products and processes which contribute to a zero-waste society. Using recycled materials by using waste as input for new products is described in chapter 6. In chapter 6 we will explore (surgical) waste as input for new products. Recycled should and could be used more. This is a fundamental concept within circular design principles but hardly used until this moment. Part III explores circular economy design principles on basis of successful examples. This part dives into real-world applications and measurable outcomes. It showcases successful circular design concepts and business models that have reshaped the market. Chapter 7: Is about leading by design. Success stories of circular concepts which have effectively changed the market with circular products and services are designated. Also entrepreneurial success stories of circular economy business models are presented. Chapter 8 investigates how to measuring effectiveness and impact of circular economy products and processes. In particular how reliable some facts are which are used by many to sell products or introduce new policies or legislation. How trustworthy is data from life cycle assessments (LCA’s)? What are the pitfalls? Is it possible to manipulate these data? Why should we characterize one-sided data from an LCA as greenwashing? Circular Economy principles, sustainability and, in broader sense, the climate discussion seem to trigger emotions. Using fundamental and reliable data is essential in order to be able to judge whether a product or process indeed reduces CO2 emissions is essential in decision-making. Chapter 9 focusses on how universities can contribute to sustainable solutions by presenting different cases which resulted in actual results which were implemented or are ready for upscaling. The role of universities as innovation hubs is highlighted through case studies with proven impact. The final chapter offers a reflective and forward-looking analysis on how circular strategies in healthcare can shape future societal developments. The authors reflect on the content in chapter 10. A final part in which a critical analysis is presented and the impact it could have on future developments and the society.

Reusing Post-consumer Insulating Glass Units (IGUs)

In this recorded presentation from glasstec 2024, Jolanda Tetteroo, from the Amsterdam University of Applied Sciences, discusses innovative approaches to reusing flat glass from post-consumer insulating glass units (IGUs). Motivated by the high energy input and virgin material demands of flat glass production, the research explores how reclaimed glass can be upgraded or directly reused in new façade applications. Initial efforts focused on assessing IGU quality in existing buildings, followed by the development of numerous upgrade strategies. The most promising result is a 50% circular IGU combining reused and new materials. Ongoing research aims to extend reuse to tempered, laminated, and coated glass, with support from industry partners and TU Delft. This work contributes to a higher level of circularity in construction materials and offers a valuable blueprint for sustainable glazing practices.
