Improvement of water absorption behavior and mechanical properties of woven jute fiber‐reinforced epoxy composites with waste eggshell filler

open access: yesPolymer International, EarlyView.
This study investigates the influence of waste eggshell powder on the water absorption and mechanical properties of jute fiber‐reinforced epoxy composites. Optimal eggshell filler content (2 wt%) significantly enhances composite performance by reducing water absorption and improving mechanical properties.

Stratospheric influence on tropical cyclone evolution

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We developed a metric based on moist static energy to detect and quantify the intrusion of stratospheric air into the inner core of tropical cyclones. High‐resolution numerical simulations show that this stratospheric interaction forms warm anomalies (high‐level warm cores) in the upper troposphere.

Sliding Mode Control in Aerospace Applications: A Survey

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

open access: yesSustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Sustainability Assessment: The Role of Entropy‐Based Indicators for Reconnecting Human' Subjectivity and Civilization With Natural Tendency of Ecosystems

open access: yesSustainable Development, EarlyView.
ABSTRACT Sustainability represents a complex issue in which scientific knowledge inevitably coexists with the subjective perception of humans in its turn influenced by civilization, cultural but also unconscious aspects. These results emerge with evidence from a critical analysis of the main definitions of sustainability delivered by credited entities (

The Myth of Decarbonized Oil: Technological Fixes, Climate Delay, and the Politics of Low‐Carbon Fossil Fuels

open access: yesSustainable Development, EarlyView.
ABSTRACT The idea of “decarbonized oil” has become increasingly visible in climate, energy, and corporate transition debates as oil and gas actors seek to reconcile continued fossil fuel production with net‐zero commitments. This article offers a critical narrative review of the concept, asking what political work the idea of decarbonized oil performs ...

Balancing coherence and resonance through linguistic framing: A longitudinal study of German biotechnology ventures' responses to the Covid‐19 pandemic

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Research suggests that ventures benefit from framing to gain audience support, yet how they utilize framing when exogenous shocks redirect attention remains unclear. Drawing on a longitudinal multiple‐case study of six biotechnology ventures following the COVID‐19 pandemic, we show how ventures balance coherence and resonance ...

Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

Multi‐Scale Engineering of Photonic Meta‐Structures With Emergent Optical Resonances via Colloidal Crystal Engineering With DNA and Microwell Templates

open access: yesSmall, EarlyView.
This work presents a bottom‐up strategy for forming meta‐structures built from DNA‐assembled nanoparticle superlattices, establishing a versatile platform for multiscale photonic materials design. Confinement stabilizes non‐equilibrium crystal habits and enables geometry and mode control independent of lattice symmetry.
