Synergic Magnetic–Dielectric Ni/Co‐Anchored Carbon Aerogels From Cellulose Nanofiber Scaffolds for Electromagnetic Shielding, Infrared Stealth, and Secure RFID Technologies

open access: yesSmall, EarlyView.
Ultralight Ni/Co‐anchored nanoporous carbon aerogels derived from TEMPO‐oxidized cellulose nanofibers integrate absorption‐dominated EMI shielding with infrared stealth. The hierarchical porous network provides dielectric/magnetic losses and suppresses thermal signatures.

Enzyme‐Functionalized Microparticles to Open the Vitreoretinal Interface

open access: yesSmall, EarlyView.
Enzyme‐functionalized microparticles facilitate diffusion of nanoparticles following ILM digestion. Active microcolloids decorated with enzymes can locally open the ILM and thereby facilitate the diffusion of passive carriers into retinal tissue. Ex vivo porcine eye models are used to determine membrane permeability and biocompatibility is evaluated in

Investigation of Serrated Flow in Intercritically Annealed Medium Manganese Steel by In Situ Synchrotron X‐Ray Diffraction

open access: yessteel research international, EarlyView.
Serrations and stepwise austenite phase transformation were observed in cold‐rolled and annealed medium manganese steels. By in situ XRD experiments, these two phenomena were studied simultaneously. The results show that DSA leads to the creation of PLC bands and load drops in the specimen.

Strain‐Induced NbC Precipitation as a Governing Mechanism for Hot Deformation Resistance in CrNiMnMoB Ultrahigh‐Strength Steels

open access: yessteel research international, EarlyView.
Strain‐induced NbC precipitation governs hot‐deformation resistance in CrNiMnMoB ultrahigh‐strength steel by suppressing dynamic recrystallization, increasing activation energy, and refining martensitic substructures. The precipitation response is controlled by temperature, supersaturation, and strain rate, with slow deformation promoting extensive NbC

Effect of Hot Rolling Temperature on Oxide Scale Formation, Grain Size, and Pickling of Stainless Steel

open access: yessteel research international, EarlyView.
The effects of finishing rolling temperature, coiling temperature, and annealing on scale formation and pickling performance are studied. Scale morphology and composition are studied via SEM‐EDS, and pickling performance is studied by evaluating scale residues and mass losses during pickling.

Humidity Ramp Protocols Systematically Underestimate Human Heat Tolerance Limits

open access: yesSafety Science and Technology, EarlyView.
Short dwell times in humidity‐ramp protocols (Δt/τ≪1 ${\Delta }t/\tau \mathit{\ll }1$) prevent human core temperature from reaching equilibrium, causing premature inflection points and systematic underestimation of critical environmental limits by ∼3°C–4°C.

Deformation and strength of grouted sleeve connectors in pre‐fabricated concrete structures: Mechanisms and analytical modeling

open access: yesStructural Concrete, EarlyView.
Abstract Grouted sleeve connectors (GSCs) are widely used in precast/prefabricated concrete structures. To ensure force transfer, connectors are often overdesigned in length. This practice has an unintended consequence of reducing the plastic deformation capacity of the connection region and hence the displacement ductility of the precast structure as ...

Five Decades of Dispute: A Triptych. Roald Hoffmann

open access: yesThe Chemical Record, EarlyView.
This article examines the historical Corey–Woodward controversy through Roald Hoffmann's personal perspective, completing a triptych on the prolonged dispute. Drawing on archival records, contemporaneous correspondence, and extensive interviews, it reconstructs Hoffmann's interactions with Corey and Woodward from the 1960s onward.

Global Disparity Within the Management of Traumatic Abdominal Vascular Injuries: Analysis of a Global Dataset

open access: yesWorld Journal of Surgery, EarlyView.
Vascular injuries are common to trauma and carry a high risk to limb and life. Integrating specialist vascular care into existing trauma systems is essential; however, global data on this topic remains limited. This study describes global patterns of abdominal vascular trauma, through secondary analysis of the Global Outcomes After Laparotomy for ...
