Graphene Materials for Sustainable Energy Applications: A Contemporary Perspective

open access: yesCarbon Energy, EarlyView.
ABSTRACT Graphene has garnered significant attention as a promising material with great potential for contributing to sustainable energy initiatives, such as RE100 (100% renewable energy initiative) and CF100 (100% carbon‐free initiative). This review aims to explore the potential of graphene for advancing renewable energy applications by highlighting

A Self‐Sustained System for Producing Green Hydrogen via Moisture Power

open access: yesCarbon Energy, EarlyView.
A multifunctional PAM‐PSSA‐MgCl2 gel enables a self‐powered Moisture‐Electricity‐Water‐Hydrogen system that harvests atmospheric water, generates electricity via moisture‐driven processes, and directly electrolyzes the collected water for hydrogen production. The material delivers 1.87 V, 450 μA cm−2 (MEG), and 1.318 g g−1 (AWH) water uptake, achieving

Substituent‐Dependent SERS Kinetics of Citrate‐Stabilized Gold Nanoparticles: Balancing Hotspot Formation and Colloidal Flocculation

open access: yesChemistry – A European Journal, EarlyView.
Reporter chemistry controls the operational window of liquid‐phase SERS. Para‐substituted benzenethiols induce distinct AuNPs colloidal regimes, ranging from delayed but stable hotspot formation to rapid flocculation‐dominated signal decay. The balance between SERS‐active‐state formation and colloidal loss defines whether a reporter provides reliable ...

Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

open access: yesChemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Opsoclonus in Pediatric Patients: Differential Diagnosis and a Practical Approach to Evaluation

open access: yesAnnals of the Child Neurology Society, EarlyView.
ABSTRACT Opsoclonus is an ocular dyskinesia characterized by involuntary, arrhythmic, multidirectional saccades. In pediatrics, opsoclonus is most commonly attributed to the rare neuroinflammatory disorder opsoclonus‐myoclonus‐ataxia syndrome (OMAS), typically considered a paraneoplastic syndrome associated with neural crest tumors. However, opsoclonus
