Abstract The development of oxygen evolution reaction catalysts featuring high activity with long-term durability in acidic media remains a major challenge for proton exchange membrane water electrolysis. Herein, we report a strategy to stabilize highly active paracrystalline IrCoO x phase by integrating it with rutil…
ABSTRACT Efficient alkaline hydrogen evolution reaction (HER) electrocatalysis requires simultaneously accelerating sluggish water dissociation and facile hydrogen desorption, yet integrating these kinetically incompatible steps within a single catalytic site remains fundamentally challenging. Here we report a hollow‐…
Introduction Candida tropicalis is responsible for a substantial proportion of invasive candidiasis cases and is recognized as the second most prevalent causative agent, only behind Candida albicans . A documented rise in invasive systemic infections and sepsis due to C. tropicalis has contributed to the increased mor…
The long-term durability of repair systems combining normal concrete (NC) and ultra-high-performance concrete (UHPC) in marine environments depends on the response of the near-interface composite region to sequential carbonation and seawater exposure. However, the effects of seawater immersion following pre-carbonatio…
The study investigates the compaction behaviour of unsaturated soil reinforced with sisal fibre and stabilized with metakaolin as partial replacement of Portland cement. The natural soil physical characterization showed that it was classed as A-7-5 in AASHTO classification system and CH in Unified Soil Classification…
N-acetylcysteine (NAC) is a thiol-containing molecule with antioxidant, anti-inflammatory, antimicrobial, and cytoprotective properties that has increasingly been incorporated into hydrogel-based biomaterials. This systematic review evaluates the strategies used to integrate NAC into hydrogels and examines their effec…
The era of nanotechnology has presented a new window of opportunity for sustainable agriculture, and the contribution of nanoparticles (NPs) to stress alleviation of abiotic stresses, with their exceptional physicochemical properties in the biological domain, has been the actual focus of researchers. Selenium nanopart…
Many mathematical and physical systems generate rapidly growing or formally infinite families of recurrent histories although their observable behaviour may depend on only a small number of effective degrees of freedom. Established methods address particular manifestations of this phenomenon through transfer matrices,…
Nanopore sensing, first conceived more than three decades ago, has seen rapid advancements in recent years in its capability in single-molecule sensing. Following immense success in nucleic acid sequencing, increased efforts have been directed to probing other biomolecules such as proteins. In recent years, our group…
Hybrid cross-laminated timber combining plantation Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.) with oriented strand board (OSB) is resource-efficient, but its bond line may govern delamination. Double cantilever beam (DCB) specimens bonded with one-component polyurethane were tested at four initial crack lengt…
This paper proposes a novel theoretical framework – the "Molecular Fate Landscape" – centered around the prediction of a molecule's entire chemical future, rather than solely focusing on a single reaction outcome. It argues for a shift in perspective from reactive prediction to the reconstruction of a comprehensive "F…
Metal–organic frameworks (MOFs) are crystalline, highly porous hybrid materials constructed from metal ions or metal-oxo clusters coordinated to organic linkers. Their exceptionally high surface area, tunable pore chemistry, and structural programmability have driven rapid growth in pharmaceutical research on MOFs ove…
The myocardial tissue-blood partition coefficient (PC or λ) of gadolinium-based contrast agents is derived from pre- and post-contrast T1 mapping (typically via MOLLI or similar sequences) as: [ \lambda \approx \frac{\Delta R1_{\text{myocardium}}}{\Delta R1_{\text{blood}}} ] where ( R1 = 1/T1 ). When corrected for hem…
ABSTRACT Zika virus (ZIKV) infection during pregnancy can result in severe fetal outcomes, yet the mechanisms of transplacental dissemination remain incompletely defined. We previously showed that ZIKV induces tunneling nanotubes (TNTs), actin-rich intercellular conduits that enable direct cell-to-cell transfer of vir…
Tungsten-based heavy alloys are promising lead-free candidates for advanced radiation shielding due to their high density and atomic number. In this study, the photon and charged-particle shielding performance of tungsten–nickel–iron (W–Ni–Fe) alloys containing 85–98 wt% tungsten was systematically investigated over a…

Leveraging the inherent 132Hz base frequency of the E8 lattice, recursive waveguides are generated through phi-scaled harmonic phase shifts across root vector chains. These waveguides propagate predictive signal integrity across multidimensional phase space, enabling real-time forecasting of emergent geometric pattern…
This study develops an integrated Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) multi-criteria decision-making (MCDM) framework to systematically evaluate and rank composite material combinations based on 24 fibers (16 natural and 8 synthetic), 15 matrices…
Abstract Near-degenerate modes can appear in guided-wave structures when two modal branches approach each other in parameter space. We study this behavior in a mirror-symmetric double-slot waveguide by combining finite-element mode calculations, field-overlap tracking, and field diagnostics. A refined scan of the slot…
This record publishes a frozen external-challenge handoff for independent adversarial evaluation of the RKMS minimal whole-chain candidate 0.1. The candidate was frozen and hashed before a builder-authored hostile challenge. The frozen candidate SHA-256 is: 8c6963e38196426b1e707967e049827b17021a30b3ba475cc433020a111f4…
