Engineering programmable peptide hydrogels for chronic refractory wounds: A mechanism‐driven framework

open access: yesBMEMat, EarlyView.
To break the self‐perpetuating pathology of chronic wounds, we propose a mechanism‐driven engineering framework for peptide‐based hydrogels. This review elucidates a hierarchical strategy—from molecular design to intelligent, multi‐functional systems—that enables these programmable biomaterials to dynamically intervene in key pathological loops and ...

Streaks on martian slopes are dry

open access: yesNature Communications
Slope streaks are dark albedo features on martian slopes that form spontaneously and fade over years to decades. Along with seasonally recurring slope lineae, streak formation has been attributed to aqueous processes, implying the presence of transient ...

Long-Term Spatio-Temporal Analysis, Distribution, and Trends of Dust Events over Iran

open access: yesAtmosphere
This study provides a comprehensive evaluation of dust events over Iran, using synoptic data from 286 meteorological stations. The dust events are classified according to synoptic dust codes as suspended dust and others (i.e., blowing dust, dust storms ...

From Green Governance to Biodiversity Strategy: The Role of Environmentally Experienced Directors in Chinese Firms

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study investigates how directors with environmental protection (EP) backgrounds influence corporate biodiversity concern (BIO) among Chinese A‐share listed firms from 2008 to 2023. Drawing on Upper Echelons Theory, we argue that directors' environmental expertise shapes firms' biodiversity strategies.

Modern‐Type Eolian Regime and Global Cooling‐Modulated Dust Provenance in the Late Paleogene of Central‐East Asia

open access: yesGeochemistry, Geophysics, Geosystems
Atmospheric mineral dust is a poorly constrained yet extremely important component of the climate system. Provenance studies from geologic dust archives are crucial to understand the drivers of the dust cycle over long time scales.
