JWST Imaging of the Closest Globular Clusters—VI. The Lowest‐Mass Objects in M 4 and the Galactic Bulge

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$

A Proposed Circular Economy Readiness Framework for the Rail Sector, A Literature Review and Conceptual Framework

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The circular economy (CE) offers a transformative approach to addressing global sustainability challenges, yet few frameworks integrate it with business strategy, systems thinking (ST) and asset management (AM), especially within critical infrastructure sectors like rail. This paper conducts a comprehensive literature review to assess existing

Quantification of Palmar and Digital Epidermal Thickness and Sweat Duct Density

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Palmar digital skin, with its high density of epidermal sweat glands and unique stratum corneum, derives its autonomic innervation from peripheral nerves. Understanding the changes to these structures could serve as objective proxy markers following peripheral nerve injury and interventions to promote regeneration.

Mechanistic Understanding of Laser‐Induced Defect Engineering of Anisotropic Cobalt Oxide Spinel Platelets in Water

open access: yesChemCatChem, EarlyView.
Pulsed laser defect engineering in liquid (PUDEL) modifies anisotropic Co3O4 platelets by inducing lattice distortions and defects while enriching {111} surfaces with hydroxyl groups and tunes the catalytic activity of the Co3O4 platelets in electrocatalytic oxygen evolution and thermocatalytic selective oxidation reactions.
