Conviction: A subscription-based decentralized network for relationship
Full text linkThe rise of online dating apps has revolutionized the way people connect, but it has also introduced significant challenges, including catfishing, fraudulent profiles, and privacy concerns. These issues undermine users\u27 trust and create a less secure environment for forming genuine relationships. We propose to build Conviction - a decentralized dating platform that leverages blockchain technology to enhance trustworthiness through digital verification and transparent user identities. By utilizing smart contracts and immutable records, the platform addresses common pitfalls associated with traditional dating apps, ensuring that profiles are authentic and secure. Additionally, a subscription-based service model is emphasized, as it not only provides a sustainable revenue stream but also incentivizes users to engage meaningfully, fostering a community focused on serious connections. This innovative approach aims to redefine online dating by prioritizing safety, authenticity, and user satisfaction
The influence of personal values on environmental sustainability in business events in Asia
Full text linkEnvironmental sustainability is no longer optional in today’s world of growing environmental and climate change concerns. Although environmental sustainability has been extensively discussed, little is known about how personal values impact environmental sustainability in the context of business events. Evidence shows that personal values influence pro-environmental behaviour. Event organisers who prioritise environmental sustainability are likely to implement environmental sustainability practices in their events. However, in the business events sector in Asia, there is a low awareness of environmental sustainability, which is closely linked to personal values. This chapter aims to emphasise the role of personal values in promoting environmental sustainability engagement in business events in Asia. Since environmental sustainability requires a collective effort, a variety of stakeholders, including organisations, academia, industry and government, are examined to understand how personal values can promote environmental sustainability engagement and address the issue of low awareness of environmental sustainability

Full text linkThe COVID-19 pandemic disrupted global supply chains, posing significant challenges to the textile and clothing industry. However, amidst these threats, there is a unique opportunity to rebuild a more sustainable and resilient fashion industry. This paper explores the shift from pre-COVID-19 business models and consumption values towards a renaissance characterized by real sustainability. By examining the transition from eco-efficiency to eco-effectiveness and from cradleto- grave to cradle-to-cradle approaches, this study emphasizes the need for the active involvement of key stakeholders in co-creating value for all. Through a comprehensive analysis of the post- COVID era, this study aims to understand textile and clothing industry professionals’ perceptions and attitudes towards sustainable design practices and identify challenges in implementing such strategies. The findings contribute to the knowledge of sustainability in the post-COVID era and provide insights and strategies for textile and clothing industry players to thrive in a sustainable and transformed landscape
Valorisation of food waste into bio-based polyurethane rigid foams: From experimental investigation to techno-economic analysis
Full text linkFood waste (FW) constitutes a significant portion of municipal solid waste and thus requires proper treatment. A ‘waste-to-wealth’ concept, in this case, urges the valorisation of FW to produce value-added products, given that such waste contains significant quantities of diverse nutrients. While most of these efforts have been focused on the recovery of carbohydrates, this paper introduces an FW biorefinery scheme to valorise FW lipids (FWLs) into bio-based polyols for polyurethane rigid foams (PURF). Considering economic viability, cost-effective dosages of enzymes for FW hydrolysis were first investigated. Subsequently, the obtained FWLs were converted into biobased polyols through stepwise epoxidation and oxirane ring-opening. Characterisation results showed that FW hydrolysis aided the development of FWL-derived polyols into PURF. Moreover, the obtained PURF exhibited excellent properties that are suitable for thermal insulation applications in the fields of civil engineering and appliances. A further techno-economic analysis demonstrated a promising profitability of valorising FW into PURF. Proven as material-intensive, critical cost drivers of the proposed valorisation scheme mainly included the price of the PURF and the chemicals required for the synthesis. The FW processing rate also significantly influenced the economic viability. By providing a successful valorisation pathway from FW to PURF and highlighting vital economic variables, this work aims to provide insights to promote the sustainable development of FW biorefineries and relevant bio-based polymer industries
Full Tailored Metal Content NCM Regeneration from Spent Lithium-Ion Battery Mixture Under Mild Condition
Full text linkMild conditioned, second-life ternary nickel–cobalt–manganese (NCM) black powder regeneration from spent lithium-ion batteries’ (LIBs) black powder mixture was demonstrated after mild conditioned p-toluenesulphuric acid (PTA)-assisted wet leaching. The NCM ratio was tailored to several combinations (333, 523, 532, and 622) by adding a suitable amount of metal (Ni, Co, Mn)-sulphate salt to the leachate. Regenerated NCM was obtained by co-precipitation with sodium hydroxide pellets and ammonia pH buffering solution, followed by lithium (Li) sintering under ambient air and size sieving. The obtained regenerated NCM powder was used for the energy storage materials (ESM) in coin cell (Li half-cell, CR2032) evaluation. Systematic characterization of regenerated NCM showed that the NCM ratio was close to the target value as assigned in the tailored process, and regenerated 622 (R622) exhibited strong activity in CR2032 coin cell testing among all four ratios with a maximum discharge capacity of 196.6 mAh/g
How Do Socio-Demographic Factors, Health Status, and Knowledge Influence the Acceptability of Probiotics Products in Hong Kong?
Full text linkIn recent years, due to growing interest in gut health, the potential benefits of probiotics on the gut have received much attention. Probiotics, now readily available in both dietary supplements and a variety of foods, have become a focal point of consumer health choices. This study aims to explore the impact of consumer-related factors, including socio-demographic profiles, health status, and probiotics knowledge, on the acceptance of probiotics products in Hong Kong. A total of 385 participants engaged in a survey, providing data for an in-depth analysis of how these factors influence attitudes toward probiotics. Findings revealed a general confidence in the safety of probiotics products among respondents; however, there was a noticeable gap in probiotics understanding. The study highlighted a correlation between probiotics knowledge and specific socio-demographic attributes, with higher educational attainment positively linked to greater probiotics awareness. Furthermore, the research indicated that women exhibit higher health consciousness and a greater propensity for probiotics consumption compared to men. Consequently, promoting enhanced probiotics education and fostering increased health awareness are crucial steps to prevent the misuse of probiotics and optimize health outcomes
