Photocatalytic production of H2O2 over facet-dependent Ti-MOF

In the past several years, Two phases photocatalysts, such as PDI/C3N4, ZIF/C3N4 or Cu2(OH)PO4/C3N4, were used for H2O2 photo-production. Few monocomponent photocatalysts for H2O2 production were reported. In the monocomponent...

A Case Study of ESL Students’ Remote Speaking Class Learning Experiences in a Canada University During the COVID-19 Pandemic

The COVID-19 pandemic forced a transfer from face-to-face (F2F) learning to remote online learning in universities worldwide. A university in southern Ontario delivered English courses to language learners living globally. This study, adopting a photo-production visual method, explored four English as a second language (ESL) students’ perceptions of this online learning compared to typical F2F learning and investigated activities enabling speaking opportunities and students’ expectations for online learning. The results showed that students perceived minor differences between online learning and F2F learning, including a non-academic English environment, a sense of community, and instant communications. The learning process involved interactive and collaborative discussions and presentations that allow students’ speaking opportunities. The online discussions contributed to students’ confidence but lacked adequate feedback towards students’ speaking skills. Students expected more types of learning activities that contribute to collaborations among peers, a sense of belonging to the online community, and examination orientated English skills.

Peripheral recovery: ‘Keeping safe’ and ‘keep progressing’ as contradictory modes of ordering in a forensic psychiatric unit

Sitting between the psychiatric and criminal justice systems, and yet fully located in neither, forensic psychiatric units are complex spaces. Both a therapeutic landscape and a carceral space, forensic services must try to balance the demands of therapy and security, or recovery and risk, within the confines of a strictly controlled institutional space. This article draws on qualitative material collected in a large forensic psychiatric unit in the UK, comprising 20 staff interviews and 20 photo production interviews with patients. We use John Law’s ‘modes of ordering’ to explore how the materials, relations and spaces are mobilised in everyday processes of living and working on the unit. We identify two ‘modes of ordering’: ‘keeping safe’, which we argue tends towards empty, stultified and static spaces; and ‘keep progressing’ which instead requires filling, enriching and ingraining spaces. We discuss ways in which tensions between these modes of ordering are resolved in the unit, noting a spatial hierarchy which prioritises ‘keeping safe’, thus limiting the institutional capacity for engendering progress and change. The empirical material is discussed in relation to the institutional and carceral geography literatures with a particular focus on mobilities.
