Photoinduced phase separation, which limits the available band gap energies for photovoltaic applications, was reported for a range of mixed-halide perovskites. A microscopic understanding of the phase separation mechanism is still lacking but may be beneficial to rationalize limitations as well as enable the design of phase-stable perovskite semiconductors. In this letter, electron-beam-induced p
The built environment accounts for approximately 32 % of the global final energy use but also holds great potential for energy efficiency still to be harnessed (Lucon et al., 2014). To develop innovative policies for energy efficiency that are capable of realizing transformative changes, we argue that there is an urgent need for new systemic evaluation frameworks that provide learning and knowledg
Multiple missiles were fired at Erbil on February 15, killing at least one civil contractor and injuring at least one American national. It is likely that the attack was conducted by an Iranian proxy in order to put pressure on President Biden to lift the sanctions against the country and return to the 2015 nuclear deal.
This paper draws on two ethnographic research projects in Japanese university sports clubs to examine the role alcohol plays in the social and cultural education of students. Over the course of a four-year membership, the university sports club is a site where members learn to negotiate drinking. This negotiation is demonstrated by the range of strategies members employ when engaging in one of the
Renewable energies can play an important role to provide electricity to rural communities. This work-study the optimum design of a hybrid hydro-wind, micro-power system in rural area. Six case studies, including the impact of hydro head, flow rate, efficiency, and head loss for micro hydropower with wind turbine hub height were implemented based on HOMER software. The simulation results show the i
Energy-efficient building designs, notably through adding insulation, can reduce energy consumption and greenhouse gas emissions by over 40 %, but may also increase risk of condensation. Therefore, a comprehensive decision analysis approach is essential for selecting optimal building envelope assemblies while considering their hygrothermal, economic, and environmental implications. This study intr
South Korea is attempting to deal with the now-universal issue of disinformation. So why did its draft bill attract such fierce criticism?
This paper investigates the dynamics surrounding energy efficiency measures in building renovation projects to understand how energy issues are dealt with at planning and design meetings for building renovations. Through a comparative analysis of case studies of residential building renovation projects in Sweden and Denmark, document studies, observations, and interviews were conducted. The study
Fires involving electric vehicles have attracted considerable attention in the media. In particular, the toxic gases released upon combustion of electric vehicles and lithium-ion batteries has been a major concern. In this study, the results of six large-scale vehicle fire tests are presented including three electric vehicles, two internal combustion engine vehicles, and one electric vehicle with
The key message is the importance of a systemic approach to handling water and energy together, both in design and in oper-ation. The paper demonstrates how renewable energy, solar photovoltaic (PV) and solar thermal, in combination with a small nutrient removal plant, provides a reliable solution for small-scale decentralized water recovery operations. The system is automated and can operate outs
Hybrid ventilation systems have become increasingly attractive, because they are considered to provide good indoor air quality (IAQ) with low energy consumption. In this study, we evaluate the performance of a hybrid ventilation system (operating on both mechanical and natural ventilation mode) by monitoring the IAQ (e.g. temperature, humidity, CO2 levels) and the energy consumption of a multifami
We report the discovery that V2331 Cygni is not an L star but an eclipsing variable with deep minima, and present a determination of the elements of the star: Epoch = HJD 2456184.296 ±0.001 and Period = 1.3886 ± 0.0001 days.

Summary: The Fracture Liaison Service (FLS) Consensus Meeting endorsed by the International Osteoporosis Foundation (IOF), Asian Federation of Osteoporosis Societies (AFOS), and Asia Pacific Osteoporosis Foundation (APOF) was hosted by the Taiwanese Osteoporosis Association on October 14, 2017. International and domestic experts reviewed the 13 Best Practice Framework (BPF) standards and concluded
Background. It is expected that fuel cells will play a significant role in a future sustainable energy system, due to their high energy efficiency and possibility to use renewable fuels. Fuels, such as biogas, can be produced locally close to the customers. The improvement for fuel cells during the last years has been fast, but the technology is still in the early phases of development, however th

Background: Degraded extracellular matrix can stimulate the innate immune system via the Toll-Like Receptor-4 (TLR4). In the pancreas, syndecan-anchored heparan sulphate (HS) on the ductal epithelium can be cleaved off its protein cores by the proteases (trypsin and elastase) and potentially activate TLR4 signalling. Methods: To investigate this signalling event, a low sulphated HS (500 mu g/ml) w
In the first of two essays in this Journal, I seek to unify the historical geography of early modern 'European expansion' (Iberia and Latin America) with the environmental history of the 'transition to capitalism' (northwestern Europe). The expansion of Europe's overseas empires and the transitions to capitalism within Europe were differentiated moments within the geographical expansion of commodi
This study examines how energy policy is framed in official documents adopted by the Baltic Assembly between 2013 and 2023. Using qualitative content analysis and securitisation theory, the study analyses 22 documents, resolutions and joint statements adopted by the Baltic Assembly, to trace how energy framing evolved in response to geopolitical developments, particularly Russia’s annexation of C
The Chernobyl catastrophe is still referred to as the biggest radioactivity fallout problem in the history of the world. The cloud that was released from the broken reactor travelled across larger parts of the European continent and the after-effects of the radiation are said to be felt and faced throughout the impacted regions up to this day – and that this process is far from over.
