A Ray of Hope: Gamma Radiation for Microplastic Remediation

open access: yesGlobal Challenges, EarlyView.
Gamma irradiation is a promising method for degrading microplastics in sewage sludge. Cobalt‐60 doses up to 116 kGy are used, achieving over two‐thirds degradation at the highest level. With further optimization, gamma irradiation could improve wastewater treatment sustainability by minimizing microplastic presence in biosolids and protecting ...

Tracheoesophageal Voicing Following Resistance‐Based Dysphagia Rehabilitation: An Exploratory Multidimensional Assessment

open access: yesHead &Neck, EarlyView.
ABSTRACT Background This exploratory study investigated tracheoesophageal voicing following 6 weeks of resistance‐based dysphagia rehabilitation with the SEA2.0, using a multidimensional assessment approach. Methods Twenty laryngectomized participants were assessed at T0 (baseline), T1 (after 6 weeks training), and T2 (after 8 weeks rest).

Imperfect Crystals of Poly(butylene succinate) Formed at High Supercooling of the Melt

open access: yesMacromolecular Chemistry and Physics, EarlyView.
X‐ray fiber pattern analysis reveals that crystallization of poly(butylene succinate) at high supercooling of the melt causes the growth of crystals of low stability with an enlarged basal plane of the unit cell and a lower crystal density compared to high‐temperature crystallization, presumably due to the presence of conformational chain defects ...

Rapid Screening of Vapor Uptake by Ultra‐Thin Polymer Films Using Surface Plasmon Resonance and Quartz Crystal Microbalance with Dissipation Monitoring

open access: yesMacromolecular Materials and Engineering, EarlyView.
Polymer membranes separate volatile organic compounds (VOCs) from air in an energy‐efficient manner. However, the screening for appropriate polymer materials is time and resource‐consuming. QCM and SPR are presented as complementary rapid screening techniques that pave the way toward a scalable high‐throughput system capable of significantly reducing ...
