Perovskite-inspired materials (PIMs) provide low-toxicity and air-stable photo-absorbers for several possible optoelectronic devices. In this context, the pnictogen-based halides Cu2AgBiI6 (CABI) are receiving increasing attention in photovoltaics. Despite extensive studies on power conversion efficiency and shelf-life stability, nearly no attention has been given to the physicochemical properties
The mixed-metal quaternary chalcohalides of group IV and V elements are a promising class of low-toxicity perovskite-inspired materials with tunable bandgaps and desirable defect tolerance. Sn2SbS2I3 is known for its broadband absorption, low exciton binding energy, ambient stability, and solution processability in thin films. However, its use in optoelectronic devices has so far been only limited
Growing oriented and monocrystalline layers of lead halide perovskites over device substrates helps to harness their outstanding optoelectronic properties. Epitaxial growth of lead halide perovskites for device fabrication is limited by the lack of lattice-matched substrates and the requirement of compact pinhole-free films. Most optoelectronic devices use amorphous substrates, hindering oriented
Are lead-free perovskite-inspired materials (PIMs) the wise choice for efficient yet sustainable indoor light harvesting? This feature article outlines how wide-bandgap PIMs can provide a positive answer to this compelling question. The wide band gaps can hinder sunlight absorption, in turn limiting the solar cell performance. However, PIMs based on group VA of the periodic table can theoretically
The perovskite-inspired Cu2AgBiI6 (CABI) absorber shows promise for low-toxicity indoor photovoltaics. However, the carrier self-trapping in this material limits its photovoltaic performance. Herein, we examine the self-trapping mechanism in CABI by analyzing the excited-state dynamics of its absorption band at 425 nm, which is responsible for the self-trapped exciton emission, using a combination
The role of the carrier-lattice interaction and associated self-trapped excitons (STEs) in broadband white-light emission in perovskite halides is one of the key aspects when aiming to develop next generation semiconductors for lighting applications. Herein, we provide microscopic insight on optoelectronic properties and electron-phonon interactions in potassium (K+) alloyed Cs2AgBiBr6, while eval
Bismuth sulphoiodide (BiSI) is considered as an excellent absorber material for toxicity-free photovoltaics (PV). Nevertheless, its applications in thin-film PV are often limited by the lack of pure phase thin-film fabrication techniques. Here, we design a novel precursor composition to fabricate pure phase thin-films by conventional spin-coating route. The as-prepared thin-films are characterized
Solar energy plays an important role in substituting the ever declining source of fossil fuel energy. Finding novel materials for solar cell applications is an integral part of photovoltaic research. Hybrid lead halide perovskites are one of, if not the most, well sought material in the photovoltaic research community. Its unique intrinsic properties, flexible synthesis techniques, and device fabr
Dye Sensitized Solar Cell (DSSC) is considered to be one of the most promising technological developments in the field of Solar Cells. It is basically a cell that imitates the process seen in plant cells to produce energy. It is a photo-electrochemical cell, considering the electron moments caused by the combined effect of the photon energy and the chemical reactions. The DSSC being transparent to
Purpose: This paper advances a performative understanding of employees’ communicative disengagement on professional social media platforms. Rather than conceptualizing disengagement as a deficit or withdrawal, the study frames it as a situated communicative performance enacted under specific sociotechnical conditions.Design/methodology/approach: The study adopts a qualitative research approach andPurpose: This paper advances a performative understanding of employees’ communicative disengagement on professional social media platforms.

Purpose: The proliferation of capitalist realism and promotional cultures have fundamentally shaped contemporary communication environments and practices. Although many accounts exist of the potential positive influence that such practices may have on society, strategic communication is still primarily used by social actors to engage in one-way “communication”, promoting their self-interests.

INTRODUCTION: Migraine aura affects approximately one-third of migraine patients. In some individuals, aura remains highly disabling due to the lack of effective, targeted treatment options. This study evaluates the effectiveness and long-term management of lamotrigine (LTG) in a clinical Cohort specifically burdened by frequent or severe aura.METHODS: A retrospective observational study was condu
Case comment, Sweden HFD 2025 ref. 58. The Supreme Administrative Court held that statutory compensation payable where a client company declined to offer permanent employment fell within the expert tax regime, emphasizing that the decisive factor was the compensation’s link to the work performed rather than who bore its cost.

Grain rotation under concurrent grain boundary (GB) migration can be observed in experiments, but poses a challenge in simulations. The need to resolve atom-scale structures while tracing GB migration over extended time scales defy most modeling approaches, including molecular dynamics (MD). In this work, phase field crystal (PFC) modeling is adopted as it permits the required combination of high
Research on migration in later life has predominantly focussed on retirement, amenities, and family-related relocation, while determinants of work-related migration has received comparatively little attention. Yet, rising labor force participation among older individuals makes understanding their work-related mobility increasingly important. Using longitudinal Swedish register data covering 1993–2
This paper examines how occupational restructuring within local labour markets shapes the employment opportunities of older workers. Using longitudinal Swedish register data covering workers across 69 functional local labour markets between 2017 and 2023, we show that greater occupational restructuring is associated with greater occupational narrowing among older workers.

Nanoparticles (NPs) are defined as particles that have a diameter less than 100 nm. Titanium dioxide (TiO2) NPs (TiO2 NPs) have gained significant attention in recent years as a possible therapeutic agent due to their unique physiochemical properties. They include tunability of the NPs, effective dopant compatibility, biocompatibility and catalytic properties. The shape and size of the NPs also pl
