With the rapid advancement of online food delivery and takeaway markets, the use of disposable chopsticks has exponentially increased in China, resulting in the reduction of forest resources and the generation of large amounts of chopstick waste. This review summarizes a variety of methods to produce eco-friendly chopsticks with the aim of enabling a second life cycle for chopstick waste. The related practical recycling systems and policies based on government experience in developed regions are proposed. Furthermore, perspectives with regard to the future development of waste chopsticks recycling systems are also discussed.

This paper,first presented on 21 October 1995 at ajoint seminar ofthe Scottish Law Commission and the Faculty of Law, University of Edinburgh, on the subject of breach of contract, considers the future development of the law in this area, first by considering its history and current state in comparative terms and drawing the conclusion that it is characterised by a mixture of Civilian and Common Law elements; second, by comparing Scots law with the provisions on breach contained in recently published proposals for a harmonised law of contract (the UNIDROIT Principles of International Commercial Contracts, the Principles of European Contract Law prepared by the Lando Commission, and the draft “code”for the United Kingdom prepared on behalf of the English Law Commission by Harvey McGregor in the late 1960s) and in international conventions on the sale of goods. Although Scots law emerges reasonably wellfrom this exercise, there are a number of points to be taken on board in any future reform, as well as some insights into important underlying principles.

A practical and concise total synthesis of tricyclic ketone 7 (CDE ring), a valuable intermediate for the synthesis of racemic camptothecin and analogs, was described (8 chemical steps and 29% overall yield). The synthesis starts with two inexpensive, readily available materials and is operationally simple to perform. It is worth mentioning that the reported protecting group-free synthesis, with advantages of a short route, would be helpful for the future development of industry-scale syntheses of camptothecin-family alkaloids.

After John Cage’s 1958 Darmstadt lectures, many European composers developed an interest in absurdity and artistic provocation. Although Ligeti’s fascination with Cage and his association with the Fluxus group was brief, the impact it had on his composition was palpable and lasting. A set of conceptual works, The Future of Music, Trois Bagatelles, and Poème symphonique for one hundred metronomes, fall clearly into the Fluxus model, even as the last has taken on a second life as a serious work. This spirit, however, can also be seen in the self-satire of Fragment and the drama and irony of Volumina, Aventures, and Nouvelles Aventures. The sketches for Aventures not only show the composer channeling this humor into a major work but also prove to be a fascinating repository of ideas that Ligeti would reuse in the years to come.

Environmental problems such as air pollution and greenhouse gas emissions are especially challenging in urban areas. Electric mobility in different forms may be a solution. While in recent years a major focus was put on private electric vehicles, e-mobility in public transport is already a very well-established and mature technology with a long history. The core objective of this paper is to analyze the economics of e-mobility in the Austrian capital of Vienna and the corresponding impact on the environment. In this paper, the historical developments, policy framework and scenarios for the future development of mobility in Vienna up to 2030 are presented. A major result shows that in an ambitious scenario for the deployment of battery electric vehicles, the total energy demand in road transport can be reduced by about 60% in 2030 compared to 2018. The major conclusion is that the policies, especially subsidies and emission-free zones will have the largest impact on the future development of private and public e-mobility in Vienna. Regarding the environmental performance, the most important is to ensure that a very high share of electricity used for electric mobility is generated from renewable energy sources.
