Methane Pyrolysis Performance in Catalytic Molten Media for Hydrogen Production From the Perspective of Bubble Column Reactor Design and Configuration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...

Experimental methods for wind tunnel studies of seed dispersal by wind

Applications in Plant Sciences, EarlyView.
Abstract The complexity and variability of natural environments make quantitative studies of seed wind dispersal challenging. Wind tunnel experiments offer a controlled alternative to investigate the mechanisms of seed wind dispersal. This review focuses on wind tunnels and the associated technologies used for studying seed wind dispersal, including ...

Lagomorph cranial biomechanics and the functional significance of the unique fenestrated rostrum of leporids

The Anatomical Record, EarlyView.
Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.

Radial capacity and hemodynamics evaluation in vitro and implantable feasibility validation in vivo of thinner bioresorbable polymer vascular stents

BMEMat, EarlyView.
A series of in vitro experiments, numerical simulations and in vivo experiments were conducted to jointly evaluate the effects of different thicknesses of bioabsorbable polymer vascular stents on their radial capacity, hemodynamics and in vivo outcomes.

The spread of non‐native species

Biological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Giving or Greening? Stakeholder Dynamics and Ex‐Military Executives

Business Strategy and the Environment, EarlyView.
ABSTRACT Firms increasingly face competing demands from different stakeholder groups, yet little is known about how these demands interact and generate strategic trade‐offs. Drawing on stakeholder theory and upper echelons theory, we investigate whether an overemphasis on philanthropic initiatives can detract from investments in green innovation, and ...

Fear of Failure as a Gendered Barrier to Building Sustainable Entrepreneurial Ecosystems

Business Strategy and the Environment, EarlyView.
ABSTRACT Drawing on four well‐established theoretical perspectives, this paper proposes an intersectional, emotionally grounded framework for understanding how gender and age jointly shape entrepreneurial perceptions across psychological, social, and cultural domains.

Barriers and Enablers of Circular Economy in Electrical and Electronic Equipment: A Systematic Literature Review

Business Strategy and the Environment, EarlyView.
ABSTRACT Rapid technological change, shorter lifecycles and rising demand for electrical and electronic equipment (EEE) are increasing waste electrical and electronic equipment (WEEE) and emphasise the need for a circular economy. This paper identifies barriers and enablers of the circular transition in EEE and outlines interventions.
