Since its emergence in 2009, perovskite photovoltaic technology has achieved remarkable progress, with efficiencies soaring from 3.8% to over 26%. Despite these advancements, challenges such as long-term material and device stability remain. [...]

In recent years, the development of non-fullerene acceptors (NFAs) has led to rapid advances in organic solar cells (OSCs), resulting in power conversion efficiency (PCE) exceeding 19%. However, the complex molecular architectures of fused ring electron acceptors require increasing steps of synthesis and purification, restricting their mass synthesis and hindering the commercialization of OSCs.

Metal halide perovskites are revolutionizing X-ray detection through a combination of low cost, solution processing, favorable optoelectronic properties, and high stopping power for high-energy ionizing radiation. While perovskite single crystals and polycrystalline wafers are considered direct X-ray converters, most medical X-ray applications are based on scintillators that shift high-energy radiation into the visible [...]

High-energy-density anode materials are crucial for achieving high performance alkali metal-ion batteries (AMIBs). In situ transmission electron microscopy (TEM) enables real-time observation of microstructural changes in electrode materials and interfaces during charging/discharging, crucial for designing high-performance anodes. [...]

Self-unawareness concerning current symptoms remains a clinical challenge in Alzheimer's disease. Reduced self-awareness likely depends on complex biopsychosocial mechanisms that comprise multiple cognitive processes, regulated by personal goals and values. [...]

Following the 3rd release of the “Emerging PV reports”, the best achievements in the performance of emerging photovoltaic (e-PV) devices in diverse e-PV research subjects are summarized, as reported in peer-reviewed articles in academic journals since August 2022. Updated graphs, tables, and analyses are provided with several performance parameters, such as power conversion efficiency, open-circuit voltage, short-circuit current density, fill factor, light utilization efficiency, and stability test energy yield.

Contemporary neuroimaging of meningiomas has largely relied on computed tomography, and more recently magnetic resonance imaging. While these modalities are frequently used in nearly all clinical settings where meningiomas are treated for the routine diagnosis and follow-up of these tumors, advances in neuroimaging have provided novel opportunities for prognostication and treatment planning (including both surgical planning and radiotherapy planning).
