Enhancing barrier properties of cellulose propionate films through the integration of ionic liquid: A study on water pressure resistance.

This study pioneers the production of porous cellulose propionate (CP) films enhanced with tetrabutylammonium styrenesulfonate ([N][SS]), an ionic liquid, to bolster their resistance against water pressure. In contrast to polymer films with ionic liquids that have high moisture permeability, the CP/[N][SS] films exhibit remarkable water resistance even under 8 bar pressure. This is due to the physical cross-linking between the [N] ions and CP's polar groups, limiting CP chain mobility and thus reducing water interaction.

Feasibility evaluation of a blended cover with activated carbon for in-situ stabilization of DDT in sediment.

Activated carbon (AC) sediment amendment is an in-situ remediation technology in which the applied AC immobilizes organic contaminant flux from sediments, thereby reducing contaminant bioavailability and associated risks. While various studies have demonstrated the feasibility of in-situ AC treatment, hesitation to apply this technology exists due to limited experience under field-specific scour conditions and hydrodynamic forces. To address this concern, we conducted a feasibility study for an AC-blended cover at the Lauritzen Channel of the United Heckathorn Superfund Site in Richmond, California, United States, which was contaminated with dichlorodiphenyltrichloroethane and its metabolites (DDx) as well as dieldrin.

Cadence-based energy expenditure in able-bodied male people comparing cadence-based energy expenditure and oxygen cost indices in able-bodied male people.

Walking is a fundamental aspect of daily life and exercise, with clinical benefits for cardiovascular health and muscle strength. However, accurately measuring energy efficiency during walking poses challenges due to equipment and spatial constraints. In this study, we proposed the cadence-based energy expenditure index (cEEI) and analyzed its correlation with the previously proposed index for measuring energy expenditure under various gait conditions.

Achieving the sustainable waste management of medical plastic packaging using a life cycle assessment approach.

Hospital waste management often classifies all waste, including uncontaminated plastic packaging, as hazardous, leading to incineration as the primary treatment method. While effective for safe treatment, incineration incurs high costs and significant environmental impacts. This study explores an alternative approach through the segregation and sustainable management of plastic packaging waste derived from medical device use to mitigate these environmental consequences.

Fabrication of Vertically Aligned InGaN/GaN Nanorod Light Emitting Diode Arrays Using Dielectrophoresis.

We report a novel strategy for vertical alignment of nanorod light emitting diodes (NRLs) by introducing dielectrophoresis (DEP) coupled with a nanohole electrode (NHE). The NHE consists of two electrodes placed at the top and the bottom separated by an insulating layer. This electrode structure allows NRLs to align within the nanoholes due to the nonuniform electric field generated across the entire region of the nanohole when a DEP voltage is applied.
