Uncovering Archaeological Treasures at Saruq al‐Hadid, UAE: Insights From Ground Penetrating Radar and Magnetic Data

Archaeological Prospection, EarlyView.
ABSTRACT Saruq al‐Hadid, located at the edge of the Rub Al‐Khali desert near Dubai's southern border with Abu Dhabi, is among the region's richest archaeological sites. Renowned for its historical role in metallurgy, trade and human habitation, the site was occupied from the Umm an‐Nar period through the post–Iron Age. Despite its significance, much of

Effective acetalization of furfural catalyzed by Fe‐ and Co‐oxalates: impact of alcohols structure on products composition

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fe‐, Co‐, and FeCo‐oxalates supported on silica gel (5 wt% metal load) were synthesized, characterized, and tested for the first time in solvent‐free furfural (FF) acetalization with C1–C8 alcohols at 70–170 °C under both conventional and microwave (MW)‐assisted conditions. The interaction of FF with linear C1–C4 alcohols yielded pincer‐shaped

Formation of a 14‐Electron Intermediate in Iridium Catalysis through Reductive Elimination: Dissociation Is Rate Determining

ChemistryEurope, EarlyView.
Dynamic NMR and trapping studies reveal that POCOP–Ir phenyl hydride complexes perform reductive coupling rapidly but dissociate benzene slowly. PCP–Ir analogs show comparatively slow reductive coupling and faster dissociation. This work experimentally clarifies aspects of C–H reductive elimination in iridium pincer complexes.(POCOP = bisphosphinite ...

Interface‐Engineered Strategy on Carbon Nanotubes to Chemical Stabilize Graphene as a Self‐Healing Fiber Electrode for Superior Capacitive Deionization

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, we developed an interface engineering strategy to prepare a high‐strength and high‐toughness fiber electrode based on holey reduced graphene oxide (HRGO) and carboxylated carbon nanotubes (CCNT) through introducing borate bonds as bridging interactions.

Sulfur‐Rich μ‐O Diiron Catalyst for Electrochemical Hydrogen Production

European Journal of Inorganic Chemistry, EarlyView.
A diferric μ‐oxido complex supported by a sulfur‐rich scaffold acts as a proton‐reduction electrocatalyst for H2 production via a μ‐hydroxido species. An aminodithiophenolate scaffold with an NS2 donor set supports diiron complex formation. The diferrous precursor activates O2, giving rise to a diferric μ‐oxido species, which acts as a proton‐reduction

High‐mobility suspended MoS2 devices with tunable threshold voltage

InfoMat, EarlyView.
Due to their atomic‐scale thickness, two‐dimensional materials (2DMs) are highly sensitive to their environment, including the substrate. By fabricating various suspended molybdenum disulfide devices, this study demonstrates that the suspended structure can shield the influence of the substrate on the properties of 2DMs, thereby enabling better ...

Freeze‐resistant, conductive semi‐interpenetrating network hydrogels enable oxidative stress regulation and enhanced wound healing

Interdisciplinary Medicine, EarlyView.
A multifunctional SFMA9/PF1 semi‐interpenetrating hydrogel with excellent conductivity, antioxidant activity, and freeze resistance effectively regulates the wound microenvironment, reduces oxidative stress and inflammation, promotes angiogenesis, and accelerates full‐thickness skin regeneration.

Sediment trap preservative choice impacts particle‐associated microbial community composition

Limnology and Oceanography: Methods, EarlyView.
Abstract Understanding and quantifying the microbial contribution to particulate organic matter (POM) flux and carbon cycling in the ocean relies largely on the collection of sinking POM. A critical aspect of evaluating microbial communities on sediment trap‐collected POM is their preservation until recovery and sample processing.

Terahertz All‐Dielectric Maxwell Fisheye Lens Waveguide Crossings via Transformation Optics

Laser &Photonics Reviews, EarlyView.
All‐silicon terahertz waveguide crossings based on Maxwell fisheye lenses are reshaped using transformation optics to interface with planar waveguides while reducing mode mismatch. Realized via subwavelength perforations in a single etching step, 2 × 2 and 3 × 3 crossings achieve broadband transmission with low loss and ultralow crosstalk across 220 ...
