Four transition metal entropy-stabilized oxide samples were synthesized with varying processing methods to create four different average grain sizes: 90 nm, 200 nm, 430 nm, and 15 μm. All samples were heat treated to form a Cu-rich tenorite secondary phase, analyzed by scanning electron microscopy and energy-dispersiv…
ABSTRACT Direct seawater electrolysis powered by renewable electricity offers a promising avenue for sustainable production of green hydrogen, yet the challenges of chloride‐induced corrosion and sluggish kinetics of oxygen evolution reaction (OER) persist with electrocatalysts. Here, a sulfur‐modified CoFe‐layered do…
The concept of quantum geometric pressure (QGP) is introduced as a novel form of internal force that arises purely from the geometric deformation of electronic band structures. In a many‑electron system, changes in the lattice geometry or external strain modify the quantum metric and Berry curvature tensors, thereby g…
ABSTRACT This work describes a general method for constructing unsymmetrical B(cage)–B single bond at room temperature via boron‐centered carboranyl radicals. The approach enables the efficient utilization of both boron atoms from B 2 cat 2 with very high yields. The key hypercoordinate boron radical intermediates are…
Accurate specification of spatial heat sources is required for liquid fuel molten salt reactors, given the redistribution of deposited energy among fuel salt, graphite, and metallic structures by gamma ray transport. In this study, a refined power deposition framework based on Monte Carlo particle transport was formul…
A mechanically reconfigurable flexible frequency selective surface (FSS) with dual‐band and polarization selectivity is proposed based on buckling‐guided 3D assembly strategy. The structure consists of periodically arranged symmetric double split‐ring resonators (SRRs) in a bilayer configuration. By releasing the pres…
This study investigates the influence of TiO₂ nanoparticles on the structural, thermal, and electrochemical properties of PVdF-HFP: NaI based polymer electrolyte films prepared by solution casting. The films were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), differential…
Antibiotic resistance among Gram-negative bacteria, particularly those capable of forming biofilms, has become a serious clinical challenge with limited treatment options. In this study, magnesium oxide nanoparticles (MgO NPs) were synthesized using a green, cost-effective approach based on aqueous leaf extract of Cym…
ABSTRACT Chiral perovskites enable spin‐polarized light emission through the chiral‐induced spin selectivity (CISS) effect, offering a pathway toward magnet‐free spin‐optoelectronic devices. However, in most CISS‐based luminescent systems, the spin‐filtering and light‐emitting functions are intrinsically coupled, whic…

The approach enables the efficient utilization of both boron atoms from B 2 cat 2 with very high yields. The key hypercoordinate boron radical intermediates are…
Abstract Low-cost titanium feedstock such as oversized additive manufacturing (AM) powders can be effectively consolidated into billets by the field-assisted sintering technology (FAST) process in the solid state with short processing times and reusable tooling. However, many engineering applications require material…
ABSTRACT Resonance‐mode manipulation is a fundamental and critical issue in electromagnetic science, underpinning diverse functions including energy localization, wave modulation, nonlinear interactions, and information processing across frequencies from microwaves to optics. Here, we propose to manipulate the mode re…
Replacing water glass (WG) with reactive silicon sources in geopolymer preparation can promote solid waste utilization and reduce carbon emissions, but the durability and degradation mechanisms of such systems under magnesium sulfate attack remain unclear. This study investigated the effect of partial substitution of…
The use of supplementary cementitious materials (SCM) can enhance concrete durability. Fly ash (FA) has been used as SCM, especially in chloride-rich environments, but its availability is decreasing due to the closure of coal-fired power plants in EU countries such as Portugal. Glass powder (GP) emerges as a promising…
Thin-walled metallic tubes are widely used as energy-absorbing components in structures subjected to impact loading due to their high crashworthiness efficiency. While the axial impact behaviour of monolithic tubes has been extensively investigated, the response of layered thin-walled tubes remains insufficiently unde…
This study presents a quantitative energy balance evaluation of an experimental claim involving deuterium enrichment observed in titanium hydride powder samples that underwent thermal cycling. The original work attributes this enrichment to a proposed two step nuclear reaction process, in which electrons are first cap…
The Palaeozoic metamorphic basement hosting the Upper Cretaceous Elatsite porphyry-copper deposit in the Etropole Mountain consists of a greenschist facies fine-grained silicate to carbonate-silicate sedimentary sequence further affected by contact metamorphic transformations in a tide aureole next to the Upper Carbon…
Data-driven design of architected biomedical structures requires controllable geometry-property relationships and experimental validation of manufacturable designs. This study proposed an inverse design framework for a dual-stiffness triply periodic minimal surface (TPMS) fusion cage by integrating parametric finite e…
Foodborne pathogens such as E. coli, B. cereus, L. monocytogenes, and S. aureus cause many illnesses in Europe each year due to traits like biofilm formation, spore production, and high resistance to harsh conditions. This study investigated plasma-treated water (PTW) as an eco-friendly antimicrobial approach and exam…
Molecular chirality requires stereochemical representations for molecular graph learning. Inspired by the connection between circular polarization and molecular stereochemistry, we propose a complex-valued message passing neural network that encodes molecular features as magnitude–phase representations and captures st…
