Mechanical stability in flexible perovskite solar cells: Interface engineering and device design

open access: yesFlexMat, EarlyView.
Statistics of the improvement methods for f‐PSCs. Abstract Flexible perovskite solar cells (f‐PSCs) demonstrate significant potential for application in next‐generation wearable electronic devices and photovoltaic building integration due to their high power conversion efficiency and excellent power‐to‐weight ratio. However, the inherent brittleness of

Donor‐acceptor fractal synergy: Decoding self‐similarity for stable organic photovoltaics

open access: yesFlexMat, EarlyView.
Morphological congruence between donor and acceptor refines the fractal structure of bulk heterojunction films and enhances their self‐similarity. This optimized multiscale morphology preserves charge‐transport pathways against external disturbances, suppresses structural degradation, and improves the operational stability of organic solar cells while ...

Myocardial Perfusion Defects in Hypertrophic Cardiomyopathy Mutation Carriers

open access: yesJournal of the American Heart Association, EarlyView., 2021
Background Impaired myocardial blood flow (MBF) in the absence of epicardial coronary disease is a feature of hypertrophic cardiomyopathy (HCM). Although most evident in hypertrophied or scarred segments, reduced MBF can occur in apparently normal segments.

Effects of testosterone and high‐dose anabolic steroids on orthodontic‐induced bone remodeling and root resorption: An animal study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This study investigates the impact of disruptions in testosterone levels on bone remodeling, root resorption, and periodontal ligament (PDL) during orthodontic tooth movement (OTM) in a pubertal male rat model. Methods Testosterone deficiency was induced through orchiectomy, and the anabolic‐androgenic steroid (AAS, testosterone ...

Integrating Ecosystem Service Benefits to Assess Ecosystem Health and Its Response to Land Spatial Structure Conflicts in Anning River Basin, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Land spatial structure conflicts (LSSC) weaken the actual benefits of ecosystem services by inducing trade‐offs among them, directly threatening regional ecosystem health (EH) and sustainable development. However, most studies have failed to incorporate ecosystem service benefits (ESB) into EH assessments and have overlooked their response to ...

On the analyzing of bifurcation properties of the one‐dimensional Mackey–Glass model by using a generalized approach

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.
