Holzdesign trifft Kunststofftechnik
(2022)
Werkstoffverbunde aus Holzgeweben in einer thermoplastischen Matrix verbinden die Idee des textilen Holzbaus mit der Faserverbundtechnologie. In einem Projekt werden Fassadenelemente aus solchen Wood Textile Composites hergestellt. Dabei spielt neben den mechanischen Anforderungen auch die gestalterische Seite und die Akzeptanz der zukünftigen Nutzer eine wichtige Rolle.

Effects of aging on the stress-induced martensitic transformation and cyclic superelastic properties in Co-Ni-Ga shape memory alloy single crystals under compression
(2022)
Co-Ni-Ga shape memory alloys attracted scientific attention as promising candidate materials for damping applications at elevated temperatures, owing to excellent superelastic properties featuring a fully reversible stress-strain response up to temperatures as high as 500 °C. In the present work, the effect of aging treatments conducted in a wide range of aging temperatures and times, i.e. at 300–400 °C for 0.25–8.5 h, was investigated. It is shown that critical features of the martensitic transformation are strongly ...

Making transdisciplinarity happen: Phase 0, or before the beginning
(2022-06-21)
Both within science and society, transdisciplinary approaches are increasingly employed to address today’s sustainability challenges. Often transdisciplinary research processes are structured in three core phases: a) problem identification and formation of a common research object; b) co-production of solution-oriented and transferable knowledge; c) embedding co-produced knowledge through transdisciplinary reintegration. In all phases of this ideal-typical model, the involvement of non-academic actors is essential ...

Diffusion of Material Flow Cost Accounting and its Contribution to Sustainable Development
(2022)
This thesis aims to analyze how further take-up of Material Flow Cost Accounting (MFCA) in practice can be encouraged to support sustainable development. To achieve the aim of the thesis, three studies on MFCA are conducted at multiple levels. The first study provides a better understanding of MFCA application at the corporate level in developing countries, which are characterized by rapid structure transformation leading to serious environmental problems. The second study considers the contextual and transformational ...

Exploring risk and sustainability performance in base of the pyramid supply chains
(2022-07)
In the contemporary business world, the real competition is not among individual businesses but rather between supply chains. Companies, which are part of efficient supply chains, are considered destined to outperform their competitors being part of inefficient supply chains. Moreover, performance has been a matter of concern for researchers for decades and is the primary aim of any firm’s existence. The definition of performance includes the performance measurement (PM) concept and further supports the notion that ...

Values as leverage points for sustainability transformation: two pathways for transformation research
(2022-08-13)
The burgeoning literature on sustainability transformation agrees that values play a key, albeit unelucidated, role on the transformation research agenda. Recent literature linking values and transformation increasingly points toward the hypothesis that values may act as leverage points for sustainability transformation. However, how transformation research can engage with values as leverage points remains a critical knowledge gap. Here, I argue that transformation research needs to distinguish between two modes of ...

Modification of self-reinforced composites (SRCs) via film stacking process
(2022-02-25)
This work presents the mechanical behavior of self-reinforced composites (SRCs) manufactured and modified via film stacking. For modification, interleaved films made of polypropylene (PP), a thermoplastic elastomer and a polyolefin engage were combined in different ways to induce the elastic modifier into the matrix material. The content of modifier was also varied in two ways. First, the films were produced out of a single material and second out of a compound. So, the same content of modifier was implemented in two ...

Influences on the mechanical properties of SRCs in a combined compacting and back injecting process
(2022-03-03)
In this research paper, the effects of the combined compacting and back-injection process to produce back-injected self-reinforced composites on the mechanical properties of the self-reinforced composites (SRCs) are investigated. For this purpose, the parameters barrel temperature, time of injection and holding pressure were varied for the back injection. Tensile and bending tests were carried out on the SRCs. The results show that the mechanical properties depend to a large extent on the process parameters. The ...

Circular bioeconomy: Actors and dynamics of knowledge co-production in Finland
(2022-09-01)
The circular bioeconomy is a highly scrutinized concept in Finland and internationally, with a high degree of polarization regarding forest utilization rates and distrust between certain actors. This offers an interesting case for an exploratory analysis of issues associated with knowledge co-production. Knowledge co-production entails the integration of different knowledge types and collaboration across multiple societal actors with potentially conflicting viewpoints and agendas. We interviewed key organizations ...

Fintech, Philanthropy, and Development: Is KYC the core problem or solution for Digital Inclusion?
(2022-04)
This paper explores the relationship between digital identity data and fintech, showing that security, and not just financialisation, is the appropriate lens to examine technologies for financial access. These technologies are supported by the nexus of finance, development, and philanthropy, ostensibly to facilitate welfare policies. But they are also part of a global security imperative. This is because the need for digital identity databases emerges from regulations to counter terror finance. Examples from India ...
