Article Citation - WoS: 4Citation - Scopus: 4Measuring Light Exposure in Daily Life: a Review of Wearable Light Loggers(Pergamon-elsevier Science Ltd, 2025) van Duijnhoven, J.; Hartmeyer, S. L.; Didikoglu, A.; Stefani, O.; Houser, K. W.; Kalavally, V.; Spitschan, M.Wearable light loggers are increasingly available for various applications, including consumer, research and clinical contexts. This study employed a survey design to systematically outline available wearable light loggers, focusing on their key characteristics and usability. Through expert meetings and iterative discussions, we developed a comprehensive survey instrument covering device properties, sensor characteristics, calibration methods, and applications. Data were collected from manufacturer-provided information and public sources for 53 wearable light loggers. Our findings highlight the diversity among wearable light loggers in terms of their device characteristics. A notable increase in the number and sophistication of wearable light loggers is visible over the past decade. However, the variability in the quality and completeness of reported device performance and validation methods emphasizes the importance of standardized practices and improved collaboration between researchers and manufacturers to enhance the reliability and usability of wearable light logging technologies in scientific research.Article Citation - WoS: 10Citation - Scopus: 10The Role of Effective Catalysts for Hydrogen Production: a Performance Evaluation(Pergamon-elsevier Science Ltd, 2025) Goren, A. Yagmur; Temiz, Mert; Erdemir, Dogan; Dincer, IbrahimIn recent years, research on hydrogen (H2) production for alternative and environmentally-benign energy solution as fuel, storage medium and feedstock has been one of the most highly demanded subjects. It aims to reduce the pressures set by carbon dioxide emissions and the depletion of fossil fuel supplies. Nevertheless, largescale H2 production is limited by its high cost and low yield. The distinct photo-electrochemical characteristics of catalysts have shown them to have great promise for enhancing the production of H2. This article presents an updated and comprehensive review of enhanced H2 production using various catalysts in biological, thermochemical, and water-based processes. Various operational parameters (reactor configuration, catalyst dosage, catalyst type, catalyst modification methods, temperature, pH, and inoculum type) are summarized to improve the H2 production performance and reduce the environmental impacts and costs of these processes. For instance, in dark fermentation, biological H2 production is enhanced by 3.2-38 % with certain metal catalysts. Overall, results revealed that catalysts, specifically inorganic catalysts such as iron, nickel, titanium oxide, and silver, have improved the production rate of H2. This review has provided the application fields and working principles of catalysts in different H2 production processes. Finally, we suggested the main concerns that need to be prioritized in the long-term advancement of H2 production using catalysts.Article Citation - WoS: 5Citation - Scopus: 5Estimation of Settlement-Induced Damage in Masonry Buildings From Displacement Measurements(Pergamon-elsevier Science Ltd, 2025) Liu, Yiyan; Burd, Harvey; Gulen, Derya Burcu; Dalgic, Korhan Deniz; Gilson, Ben; Ilki, Alper; Acikgoz, SinanIn current engineering practice, building damage due to nearby ground excavation activities is typically quantified by processing displacement measurements. Building displacements at discrete points are used to determine deflection measures (such as angular distortion) which are then employed to estimate building strains using elastic beam models; damage is subsequently categorised according to the limiting tensile strain criteria. The reliability of this procedure relies on the extent to which the equivalent beam models employed in the analysis provide a realistic representation of the building behaviour. However, few published investigations are available on this issue. The current paper provides an appraisal of displacement-based building damage estimation techniques by employing digital image correlation displacement data collected from a recent experimental campaign on the settlement response of three half-scale masonry buildings. The results demonstrate that the treatment of buildings with equivalent beam models does not capture building deformation kinematics, potentially leading to inaccurate estimations of damage severity and location. An alternative strain interpretation procedure, inspired by an equivalent frame idealisation of a building fa & ccedil;ade with openings, is proposed. This procedure, which uses a limited number of displacement measurements, offers a robust interpretation of strains. Its effectiveness in estimating damage is assessed through experimental data. It is demonstrated that the current limiting tensile strain criteria need to be modified to provide a reliable estimation of crack widths when using the equivalent frame idealisation.Article Citation - WoS: 7Citation - Scopus: 7Hydrogen Production From Energetic Poplar and Waste Sludge by Electrohydrogenesis Using Membraneless Microbial Electrolysis Cells(Pergamon-elsevier Science Ltd, 2024) Goren, A. Yagmur; Kilicaslan, A. Faruk; Dincer, Ibrahim; Khalvati, AliMembraneless microbial electrolysis cells (MECs) are potentially considered to produce biohydrogen (bioH2) in a green manner and simultaneously minimize agricultural and wastewater facility wastes. However, effective, sustainable, and cost-effective system configuration and improvement of operating variables, working at ambient conditions, are needed to make the MEC a sustainable process. Therefore, this study investigates the bioH2 production from poplar leaves and anaerobic sludge mixture by incorporating nanomaterials comprising Al2O3, MgO, and Fe2O3 metal oxides at various dosages. Moreover, the effects of applied cell voltage (0.5-1.5 V) and inoculum amount (20-40 mL) on bioH2 production and organic matter removal performance are evaluated. The maximum bioH2 production value is 417 mL at an applied voltage of 1.5 V with a chemical oxygen demand (COD) removal efficiency of 37.6 % under operating times of 5 min using 40 ml of inoculum. The bioH2 production of the MEC system is reduced with the decrease in inoculum amount. The highest bioH2 production of 828 mL is obtained at improved conditions in the presence of 1 g of Fe2O3 metal oxide. Overall, this study provides the potentiality of simultaneous waste minimization and bioH2 production under ambient conditions that highlight the waste-to-energy pathway for membraneless and green bioelectrochemical process.Article Citation - WoS: 14Citation - Scopus: 16Hybridising Counterurbanisation: Lessons From Japan's Kankeijinko(Pergamon-elsevier Science Ltd, 2024) Dilley, Luke; Gkartzios, Menelaos; Kudo, Shogo; Odagiri, TokumiThis paper examines the discourse and material manifestation of kankeijinko over bar , a phrase used in Japan to describe, primarily, highly mobile groups of urbanities who make regular visits to the countryside. Drawing on Japanese grey literature, secondary data analysis, national-level policy reports and exploratory fieldwork in the northwest of Japan, we argue that the concept of kankeijinko over bar offers a view of rural mobility quite different from more established views of counterurbanisation, at least in the way that it has been captured in the global north. As a concept, kankeijinko over bar invites us to move beyond simple and binary taxonomies of migration and settlement, and destabilizes the notion of rural vitality as being linked to rural populations that are spatially fixed and bounded. Further, the promotion of kankeijinko over bar in policy discourses in Japan has the potential to support new hybrid, fluid and place-based rural lifestyles that contribute to an interconnected global countryside. On the other hand, the discourse of kankeijinko over bar might privilege certain modes of rural mobility and being, circumscribing the potentialities of these mobile groups.Article Citation - WoS: 10Citation - Scopus: 15Introducing Climate-Related Counterurbanisation: Individual Adaptation or Societal Maladaptation?(Pergamon-elsevier Science Ltd, 2024) Scott, Mark; Gkartzios, Menelaos; Halfacree, KeithClimate disruption today and anticipated future climate breakdown are reshaping demographic and spatial processes, with profound consequences for societies across the globe. Specifically, migration can become a key strategy to attempt to respond to and cope with environmental change. This paper seeks to make sense of one type of migration, counterurbanisation, in this climate breakdown era. It provides conceptual clarity to what is termed 'climate-related counterurbanisation' vis-`a-vis wider climate-induced migration and positions climate disruption within the counterurbanisation literature. Climate-related counterurbanisation is presented as a largely voluntary movement down the settlement hierarchy as a direct or indirect response to climate change, with positive representations of 'rurality' central to the relocation decision: individual adaptation. However, it is mediated by numerous geographically variegated and specific environmental, cultural, social and economic factors. Indeed, it may ultimately come to be seen more as maladaptation than adaptation. While moving from urban to rural may make sense at individual household level, such relocations can overall have much more negative impacts on host rural communities or the urban people left behind.
