Aqueous Zinc‐Based Batteries: Active Materials, Device Design, and Future Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
This review conducts a comprehensive analysis of aqueous zinc‐based batteries (AZBs) based on their intrinsic mechanisms, including redox reactions, ion intercalation reactions, alloying reactions, electrochemical double‐layer reactions, and mixed mechanisms, systematically discussing recent advancements in each type of AZBs.

Catalytic 1,2‐Migratory Insertion in a Bismuth Redox Platform: Reductive Arylation of Aldehydes

open access: yesAngewandte Chemie, EarlyView.
We report a multicomponent reaction involving an aryl halide, an aldehyde, and a silane derivative, facilitated by low‐valent bismuth redox catalysis under mild conditions. The protocol represents an unprecedented example of four elementary organometallic steps at a Bi center within the catalytic cycle.

Unprecedented Unidirectional Chiral Luminescence and Self‐Assembly Morphologies‐Mediated Multifarious Circularly Polarized Phosphorescence From Au(I)‐Based Enantiomers

open access: yesAggregate, EarlyView.
Herein, we develop a pair of force‐responsive chiral Au(I) complexes, and the enantiomers can form multiple different assembled morphologies accompanied by multifarious CPP signals. Impressively, the unprecedented unidirectional CPP is observed from this pair of enantiomers in the same aggregated states.

Controlling the Helicity and Handedness of Polyaromatics with Isobenzofuranophane

open access: yesAngewandte Chemie, EarlyView.
Isobenzofuranophanes are introduced as helical synthons that enable late‐stage helicity induction and control in polyaromatics. This remote tethering approach allows precise control over the handedness and pitch of [5]helicenes via the tether length, inducing significant molecular distortion and affecting chiroptical properties.

Thermal maturity assessment of some Egyptian crude oils as implication from naphthalene, phenanthrene and alkyl substituents

open access: yesEgyptian Journal of Petroleum, 2021
The study is paying attention to the variation of the comparative abundance of naphthalenes, phenanthrenes of aromatic fractions separated from seven different Egyptian crude oils, and were studied by GC–MS to assess the thermal maturity and recognize ...

Well‐Designed Organic Semiconductors With Tunable Resistive Switching Behaviors for Multilevel Storage and Neuromorphic Computing

open access: yesAggregate, EarlyView.
A novel strategy is proposed to design and synthesize furan‐annulated naphthalenes for high‐performance memristive behaviors by introducing an electron acceptor (trifluoromethyl) or donor (methoxy). The former, with donor–acceptor pairs, demonstrates high‐performance bipolar digital memristive behaviors with multilevel storage characteristics.
