    Abstract This paper identifies and evaluates interventions for addressing the structural conditions in food systems that contribute to food waste. Within the food waste literature, an emerging strand of research is focusing on how food waste has structural causes that are embedded within the fundamental characteristics of food supply chains. This paper draws upon empirical research examining the causes of food waste in the Australian horticulture industry as a context from which to advance understandings of how to dismantle mechanisms of waste creation inherent in food systems. Identifying appropriate interventions to alter the dynamics of food waste production is an important part of addressing food waste as a structural issue, yet such interventions are subject to system resistance to transforming the normal operation of incumbent food systems. Guided by socio-technical transitions theory, this paper investigates ways to increase regime pressure to overcome systemic resistance through the frames of “creative regime destabilisation” and “alternative niche support”. A theoretical integration of socio-technical transitions with systems thinking provides deeper insights into the transformative potential of diverse interventions through the identification of ‘deep leveraging points’, proposing a tangible transition agenda for industry, policy and research.

    Abstract Diamondoid molecules and their derivatives have attracted attention as fascinating building blocks for advanced functional materials. Depending on the balance between hydrogen bonds and London dispersion interactions, they can self-organize in different cluster structures with functional groups tailored for various applications. Here, we present a new approach to supramolecular aggregation where self-assembly of diamondoid acids and alcohols in the ultracold environment of superfluid helium nanodroplets (HNDs) was analyzed by a combination of time-of-flight mass spectrometry and computational tools. Experimentally observed magic numbers of the assembled cluster sizes were successfully identified and computed cluster structures gave valuable insights into a different conglomeration mode when compared to previously explored less-polar diamondoid derivatives. We have confirmed that functional groups acting as good hydrogen bond donors completely take over the self-organization process, resulting in fascinating pair-wise or cyclic supramolecular assemblies. Particularly noteworthy is that mono- and bis-substituted diamondoid derivatives of both series engage in completely different modes of action, which is reflected in differing non-covalent cluster geometries. Additionally, formed cyclic clusters with a polar cavity in the center and a non-polar diamondoid outer layer can be of high interest in porous material design and provide insights into the structural requirements needed to produce bulk materials with desired properties.

    Abstract Until recently, food waste prevention intervention has largely offered ‘end of pipe solutions’ that focus on causes of food waste at specific points in supply chains and on dealing with the physical waste material itself. Recent research has taken a different approach by emphasizing the systemic nature of the food waste problem and the need for its in-depth exploration. This paper offers a systems-based understanding of food waste, which allows for an account of the interconnected processes that underpin waste creation along the whole supply chain. Through a qualitative inquiry on practices and processes of surplus and waste creation in the Australian horticulture industry, the research findings precisely delineate ‘surplus-to-waste lock-ins’. That is, the institutional, cultural, and material factors that enable the creation of food waste through the related categories of over-production and surplus formation. The article’s identification and analysis of surplus-to-waste lock-ins is grounded in a socio-technical transitions perspective and extends transition studies to agrifood systems and horticultural food waste. This research positions systemic food waste theoretically as a symptom of ‘system-lock-in’, which may thwart efforts to prevent food waste, and thus bridges micro and macro levels of analysis. These findings translate into three key recommendations for industry, policy and research: that approaches addressing systemic processes of waste creation are essential to unlocking food waste prevention, that food waste prevention should target the identified system processes contributing to food chain lock-ins, and that transparent monitoring and disclosure of food surplus is a prerequisite for systemic food waste prevention across the whole supply chain.

    Abstract Nanoparticles consisting of three different materials in a layered core@shell@shell structure are synthesized in cold helium droplets by sequential doping. Upon the formation of Au core particles, a first shell layer is formed by adding either Ar, isopropyl alcohol, or hexane. Subsequently, the droplets are doped with rhodamine B (RB) molecules; fluorescence spectra recorded upon laser excitation at 532 nm provide insight into the structure of the formed complexes. For the two-component Au@RB system, the RB fluorescence is quenched in the presence of the Au core. If an intermediate isolating shell layer is introduced (Au@shell@RB), the fluorescence increases again. The results demonstrate that shell-isolated nanoparticles can be formed inside He nanodroplets and functionalized

    Abstract Preventing food waste is a major global challenge to the sustainability and security of the environment, society and economy. In response to that challenge, a plethora of initiatives addressing food waste have formed in recent years. These initiatives focus on aspects such as the efficiency of resource use, reduction of supply chain food waste, food donations and rescue, consumer behaviour, and above all, innovative ways to add value to food surplus and waste. What many initiatives have in common is that they mainly deal with food waste once it exists rather than preventing it from occurring in the first place, which might thwart efforts to increase long-term food systems sustainability. The idea of food waste prevention itself is beset by several conceptual paradoxes: it is considered the most preferred method to manage waste—which it was supposed to prevent in the first place, and it is an ambiguous ecological behaviour lacking the tangible characteristics of waste composting or recycling (i.e. prevention by its nature is invisible). Most importantly, food waste prevention, like other major sustainability challenges, appears to be in a fundamental conflict of interest with current economic norms and practices. In response to these dissonances of prevention and the inability of waste management to reduce the creation of food waste, researchers have proposed a number of new approaches, including the re-appraisal of food overproduction as a key cause of food waste. Accepting Mourad’s (Environ Soc Berkeley J Sociol 59:26–33, 2015) challenge to “think outside the bin”, this work proposes a “Prevention Paradox” framing as a conceptual link between the bodies of research on food overproduction and food waste prevention, offering a more holistic approach to this major sustainability challenge.
