Maintaining hexagonal structures through interfacial positioning of crosslinkers for nanofiltration.
J Colloid Interface Sci
December 2024
Hypothesis: Optimizing interfacial positioning of crosslinkers within a reactive self-assembled hexagonal lyotropic liquid crystals (HLLC) system could assist in retaining the hexagonal structure during polymerization and thereby improving water filtration performances of the as-synthesized nanofiltration membranes.
Experiments: The positioning of the hydrophilic crosslinker, poly (ethylene glycol) diacrylate (PEGDA), within the reactive HLLC system was systematically investigated using H and C solid nuclear magnetic resonance (NMR) and small angle X-ray scattering (SAXS) techniques. The structural variation and water filtration performances of these HLLC systems with/without crosslinkers after polymerization were further studied using grazing incidence SAXS (GISAXS) and crossflow filtration tests, respectively.
Article Synopsis
- The study examined the impact of night-shift work on hormone levels in female hospital workers, particularly focusing on steroid hormones, vitamin D, and melatonin.
- Ninety-seven female participants included nurses on a rapid rotating night-shift schedule and day workers, with various hormonal levels measured in serum and saliva.
- Findings indicated that night-shift work led to higher levels of certain stress-related hormones while not affecting overall circadian rhythms of cortisol and melatonin, nor increasing estradiol levels.
Innovative Photoprotection Strategy: Development of 2-(Benzoxazol-2-Yl)[(2-Hydroxynaphthyl)Diazenyl] Phenol Derivatives for Comprehensive Absorption of UVB, UVA, and Blue Light.

Overexposure to blue light due to the excessive use of electronic devices has been implicated in premature skin aging and eye damage, among other injuries to health. This study aimed to synthesize two azo derivatives of the 2-(amino-2'-hydroxyphenyl) benzoxazole and explore their potential as UV and blue light filters, proposing a new spectral profile. The synthesis of the heterocyclic compounds involved condensation reactions and diazotation.

This study presents a novel approach for creating multistimuli-activated PDA NB-armored emulsions, encapsulating perfluorohexane (NB-H) and perfluoropentane (NB-P) cores, with applications in controlled delivery and ultrasound imaging. Thermal and photothermal activation induced distinct responses in the emulsions, as evidenced by optical microscopy and thermogravimetric analysis.

- The digital economy's growth has affected labor markets, particularly in food delivery, raising concerns about occupational safety and health (OSH) for riders in Milan, Italy.
- The study involved structured interviews with 240 delivery riders, primarily male and under 35, revealing high rates of road accidents and health issues like musculoskeletal disorders.
- Findings highlight the need for collaborative efforts among policymakers and stakeholders to improve OSH standards and working conditions for food delivery riders, contributing to sustainable development goals.
