Perovskite solar cells (PSCs) have demonstrated rapid advancements in power conversion efficiency (PCE) in recent years, reaching 25.7% within a decade. However, the stability of PSCs lags behind in comparison, with short lifetimes being a major obstacle to commercialization. The various layers and interfaces within PSCs play a significant role in both PCE and stability. Spiro-OMeTAD is the most c

Lead halide perovskites (LHPs) photoelectrodes for photoelectrochemical (PEC) water splitting are promising candidates for solar-to-fuel conversion. However, the poor stability of LHPs in aqueous electrolyte media, together with the toxicity of lead, restricts the practical application of LHP photoelectrodes. Herein, we report the first-ever colloidal synthesis of quaternary Cu1.4Ag0.6BiI5 nanocry

As the adverse impacts of hydrological extremes increase in many regions of the world, a better understanding of the drivers of changes in risk and impacts is essential for effective flood and drought risk management and climate adaptation. However, there is currently a lack of comprehensive, empirical data about the processes, interactions, and feedbacks in complex human-water systems leading to

We coordinate interconnected agents where the control input of eachagent is limited by the control input of others. In that sense, the sys-tems have to share a limited resource over a network. Such problems canarise in different areas and it is here motivated by a district heating ex-ample. When the shared resource is insufficient for the combined needof all systems, the resource will have to be s

BACKGROUND: Patients with chronic respiratory failure treated with long-term oxygen therapy (LTOT) often have severe breathlessness, impaired exercise performance, and high but variable mortality that is difficult to predict. We aimed to evaluate breathlessness and exercise performance upon starting LTOT as predictors of overall and short-term mortality.METHODS: This was a longitudinal, population

PURPOSE: To explore if aspects of the physical home environment are related to rehabilitation outcomes among community-living persons poststroke.BACKGROUND: Research demonstrates that healthcare environments are important for high-quality care and that the design of the physical environment is associated with improved rehabilitation outcomes. However, relevant research focusing on outpatient care

If the use of military force is neither compatible with loving one's enemies nor better at countering oppression and mass killing than nonviolent methods, why should Christians engage in it?

There has been widespread debate about whether the way in which we measure economic activity is fit for purpose in the twenty-first century. One aspect to this debate is to move away from measuring a nation’s income (GDP), towards monitoring a nation's assets (their inclusive wealth), as a better indicator of sustainable economic development. We provide the first critical comparison of the approac

BACKGROUND: Qigong includes training for body and mind, one method is Zhineng Qigong. Scientific literature on qigong for chronic low back pain (LBP) is sparse. This study aimed to investigate feasibility including evaluation of a Zhineng Qigong intervention for pain and other lumbar spine-related symptoms, disability, and health-related quality of life in patients with chronic LBP and/or leg pain
