Abstract

Abstract Hydrothermal carbonization (HTC) is a promising technology for waste valorisation and nutrient recovery to achieve sustainability. HTC converts organic waste into hydrochar, a carbon‐rich solid with numerous surface functionalities that can be used for energy and wastewater treatment. In this review, we highlight the potential of hydrochar‐based technology for improving the performance of anaerobic digestion (AD) systems and downstream applications of nutrient‐laden hydrochar. We identify knowledge gaps in hydrochar production, performance in AD systems and nutrient recovery, including the need for larger‐scale production facilities, multielement adsorption studies, and computational modelling. Techno‐economic analysis and life cycle assessment of hydrochar applications are critical to evaluating the commercial viability of this technology. Overall, hydrochar‐based technology offers a sustainable solution for waste management and resource recovery, with potential socioeconomic benefits for developing economies. The deployment of hydrochar‐based technology will directly address key issues highlighted in the United Nations' Sustainable Development Goals such as Clean water and sanitation (SDG 6); Zero hunger (SDG 2); and Climate action (SDG 13) thereby contributing to a more sustainable future.

23. Materials and wear modelling of a cobalt-chromium alloy in self-mated reciprocated sliding

Author

Cross, Paul Sebastian George and Wood, Robert

Abstract

Many sliding applications depend upon cobalt-based hard-facing materials, due to their excellent friction and wear properties, where it is not possible to lubricate the mating surfaces. However, wear produced in such systems present a significant health risk and so there is motivation to understand cobalt-based wear to aid the development of cobalt-free alternatives. The focus of this work is to build a mechanistic model of sliding wear for a given cobalt-based hard-facing alloy. The chosen numerical approach was informed by a series of delineating simple reciprocated sliding wear tests, in accordance with Rolls-Royce research aims, as a stepping stone to more complex environments. Wear testing of a cobalt-based hard-facing alloy, Stellite 6TM, was performed under selfmated reciprocating dry room-temperature conditions. The wear-rate as a function of load was not constant, suggesting a different model of wear than typical linear models of wear. Probing the debrWis morphology, surface topography, and subsurface behaviour of the alloy revealed plate-like particle formation and separation via subsurface material rupture. Unique to this thesis, the sliding wear behaviour for the load range of 400 N to 1000 N was interpreted as belonging to a ratcheting-type wear mechanism. A multiscale model of sliding wear was developed as part of this project. This model incorporates a modified microscale ratcheting wear subroutine into a standard finite element model of sliding wear via statistical homogenisation. This approach is a novel extension to the typical numerical models of sliding wear, and allows the user to see how macroscopic wear is affected as the result of material properties, evolution of surface roughness, or microscale imperfections. The model predicts the correct scale of wear, close to a wear-rate of 1×10−14 m3/Nm. Presently this model only accounts for the purely mechanical aspect of wear, but may be adapted for use in synergetic tribocorrosion models to better understand how Stellite 6TM behaves in a nuclear environment.

29. Connecting the disconnected: analysis of a virtual exchange during the worldwide COVID-19 pandemic

Abstract

This paper contributes to the ongoing discussion about the use of virtual exchange for the teaching and learning of languages. The project was designed as a Spanish language conversation exchange that connected students via synchronous Zoom sessions. Following a pilot semester that took place in spring 2019, the exchange was then repeated with a new group of students during the spring 2020 term, the same semester during which the COVID-19 pandemic spread throughout the world. The exchange took place over a two-week period and pairs were formed between students enrolled in a graduate level pre-service Spanish language program in Spain and undergraduate intermediate Spanish students in the US. Groups were asked to complete five topic-based conversation sessions. Individual exchange sessions were recorded and transcribed. Exchange participants also completed a survey about their experiences. Findings from the recorded sessions, transcript analysis, and surveys show that the virtual conversation exchange was successful and that difficulties such as technology and scheduling, both recurring issues that have been noted in previous studies of telecollaboration (Helm, 2015), were not significant barriers. Because the virtual exchange took place during the onset of the COVID-19 pandemic, the primary focus of this study was to examine how students utilized the exchange as a way to stay connected during a time of mass disconnection.

36. Kinetic and isotherm insights of Diclofenac removal by sludge derived hydrochar

Abstract

Abstract Recently, hydrothermal carbonization emerges as the most viable option for the management of solid waste with high moisture content. Sludge derived hydrochar is used as an adsorbent for emerging contaminants or micro-pollutants in the domain of sustainability. Current study demonstrates the KOH activation of hydrochar produced from paper board mill sludge and evaluates its removal potential of a Non-steroidal anti-inflammatory drug, Diclofenac from aqueous solution. The activated hydrochars exhibited porous, spherical micro-structures with higher fraction of oxygenated functional groups paving way for the efficient adsorption of Diclofenac. The effect of initial Diclofenac concentration and contact time was ascertained using adsorption kinetics and isotherms. The adsorption kinetics exhibited second-order reaction for all adsorbents indicating higher coefficient of determination (R2 > 0.9). The Diclofenac adsorption on hydrochars followed Langmuir isotherm model with the post-activated hydrochar recording a highest adsorption capacity of 37.23 mg g−1 in 40 mg L−1 initial Diclofenac concentration at 15 h equilibrium time.
