GaPt alloy in HZSM ‐5 for highly stable ethane dehydroaromatization

Abstract The dehydroaromatization of ethane to aromatics is a highly attractive yet challenging route for valorizing the second‐most abundant component of natural gas. Here, we report bimetallic xGa0.8Pt/HZSM‐5 catalysts that exhibit markedly enhanced stability and coke resistanc...

Supramolecular Polymerization of Triphenylamine[3]arenes for Switchable and Stimuli‐Responsive Chiroptical Properties

ABSTRACT The design of advanced photonic materials with integrated stimuli‐responsive properties remains coveted yet challenging. Herein, we demonstrate that chiral supramolecular assembly of triphenylamine[3]arenes (TPA[3]s) offers an efficient and modular solution to address th...

Electrical signal transmission across electrolyte junctions separated by atomically-thin graphene

Signal transmission across membranes is usually mediated by the permeation of molecular species. Here we show that atomically thin graphene crystals, although impermeable to any ions or molecules, can transmit interfacial electrical potentials across electrolyte junctions without...

A Twisted σ-Bond Mediated by a Lone-Pair in Elemental Sulfur

Abstract The lone pair is a foundational concept in chemistry, classically regarded as a localized, nonbonding entity. However, a persistent anomaly in elemental sulfur (S8) challenges this view: the observed electron density along the S–S bond shows a bimodal distribution that i...

Scalable retinal projection augmented reality displays with confocal dual-ellipsoidal combiner

Abstract Compact near-eye displays (NEDs) with large visual scope, high resolution, and high optical efficiency are essential for advanced augmented reality (AR) applications. However, existing AR NED architectures suffer from inherent trade-offs among these metrics, restricting...

Interpenetration Transformation of Diacetylene Metal–Organic Frameworks for Topochemical Polymerization

Achieving precise control over topochemical polymerization in diacetylene metal-organic frameworks (MOFs) remains a huge challenge due to the stringent requirements for molecular alignment and ordered stacking. Herein, we report two interpenetrated MOFs (twofold interpenetrated C...

Photoactive Biaxial Ferroelectric Polarizations in Flexible Hybrid Metal‐Halide Single‐Crystal Thin Films Driving Multidirectional Self‐Powered Optical Communications

ABSTRACT Flexible optoelectronic devices hold great potential in fields such as health monitoring, human‐machine interactions and light communications. The emerging two‐dimensional (2D) hybrid metal‐halide perovskite ferroelectrics are highly attractive for optoelectronic applica...

Energetic Metal–Organic Frameworks With Enhanced Catalytic Performance for Ammonium Perchlorate Thermal Decomposition

ABSTRACT Ammonium perchlorate (AP), the pivotal oxidizer in composite solid propellants, is often constrained due to its high decomposition temperature and sluggish heat release. Here, we proposed a structural co‐assembly strategy which synergistically assembles energetic moietie...
