MXenes as a Versatile Platform for High‐Energy‐Density Asymmetric Supercapacitors

open access: yesCarbon Energy, EarlyView.
MXenes with high conductivity and tunable surface chemistry are reviewed as advanced electrodes for asymmetric supercapacitors. MAX‐phase synthesis, surface and interlayer engineering, defect modulation, and composite designs are discussed, highlighting enhanced ion transport, pseudocapacitance, energy density, cycling stability, and sustainable routes

Comparative study of modern heuristic algorithms for global maximum power point tracking in photovoltaic systems under partial shading conditions

open access: yesFrontiers in Energy Research, 2022
Under partial shading conditions (PSCs), photovoltaic (PV) generation systems exhibit multiple local and a single global maximum power point. Consequently, global maximum power point tracking (GMPPT) is required to improve the performance of PV systems ...

Tuning Stability and Optoelectronic Properties of CsSnI3 Via Rare‐Earth Doping

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sn‐based halide perovskites are promising optoelectronic materials but are limited by poor stability. Thus, rare‐earth elements (RE) doping in CsSnI3 addresses this limitation, significantly enhancing thermodynamic, mechanical, and chemical stability, while simultaneously tuning electronic characteristics and modulating optical responses in the ...

A New Golden Eagle Optimization with Stooping Behaviour for Photovoltaic Maximum Power Tracking under Partial Shading

open access: yesEnergies, 2023
Solar photovoltaic (PV) systems often encounter a problem called partial shading condition (PSC), which causes a significant decrease in the system’s output power.

Comparative Assessment and Benchmarking of Metaheuristic Algorithms for Dynamic Photovoltaic Array Reconfiguration Under Diverse Shading Environments

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT The solar photovoltaic (PV) installations, which are essential for renewable energy systems, are vulnerable to partial shading, resulting in considerable power losses and operational inefficiencies. The dynamic reconfiguration of PV arrays has become an effective strategy to mitigate these effects by adaptively modifying the array topology to ...

Normothermic Machine Perfusion vs. Static Cold Storage for DBD Liver Transplantation in High‐MELD Recipients: A Single‐Center Retrospective Study

open access: yesJournal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background and Purpose While normothermic machine perfusion (NMP) has benefits over static cold storage (SCS), its efficacy in high‐acuity recipients with high Model for End‐Stage Liver Disease (MELD) scores, particularly using a back‐to‐base application model, is not well established.

Frequency of ZFHX3‐Mediated Spinocerebellar Ataxia 4 in a US Undiagnosed Ataxia Cohort

open access: yesMovement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia 4 (SCA4) is a late‐onset dominant ataxia with neuropathy caused by exonic GGC repeat expansion in the ZFHX3 gene thought to originate from a Swedish founder event. The GC‐rich expansion is highly thermodynamically stable, posing challenges for standard clinical genetic testing methods.

Drivers of individual plant species contributions to β‐diversity are scale‐dependent

open access: yesOikos, EarlyView.
Species introductions and local extinctions of native species are driving biotic homogenisation in plant communities by reducing β‐diversity. Individual species vary in their contributions to β‐diversity (species contribution to β‐diversity; species‐β), yet our understanding of how species characteristics shape these contributions remains limited ...
