Argon Cold Plasma Modification of Polyethylene Films to Tailor Surface and Barrier Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
Argon cold plasma treatment of low‐density polyethylene (LDPE) and high‐density polyethylene (HDPE) films induces major changes in surface chemistry and morphology. Contact angles decrease significantly while surface energy increases, improving wettability. FTIR confirms the formation of polar functional groups, while pronounced etching, roughness, and

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Experimental methods for wind tunnel studies of seed dispersal by wind

open access: yesApplications 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 ...

Atomically Thin Sieves: Two‐Dimensional Materials for Membrane Separation

open access: yesAdvanced Physics Research, EarlyView.
Atomically thin membranes derived from 2D materials overcome the inherent selectivity‐permeability trade‐off in conventional separation technologies. This perspective elucidates transport mechanisms for gases, water, and ions, surveys fabrication strategies including top‐down pore engineering and bottom‐up synthesis, highlights recent experimental and ...

Effect of Ramped Oxygen Flow During Magnetron Sputtering on the Structural, Optical, and Photoelectrochemical Properties of WO3‐x Thin Films

open access: yesAdvanced Physics Research, EarlyView.
A compositionally graded WO3‐x thin film was engineered through a controlled linear increase of oxygen flow during reactive magnetron sputtering. This deposition strategy yields a gradual transition from an oxygen‐deficient, conductive bottom layer to a more stoichiometric and crystalline surface layer, forming an intrinsic gradient homojunction.
