Attenuation of progressive surface gravity waves by floating spheres.

Laboratory experiments were performed to investigate the attenuation of progressive deep-water waves by a mono-layer of loose- and close-packed floating spheres. We measured the decay distance of waves having different incident wave frequency and steepness. The attenuation of waves was strong if the surface concentration of particles was close-packed, with the decay distance being shorter for incident waves with higher frequency and steepness.

Polarized epithelial cells are compartmentalized into apical and basement membranes with asymmetrically distributed proteins. This study aimed to establish a method for culturing epithelial cells at the fluorinated oil (Novec-7500) microdroplet surface for the formation of epithelial polarity, which is desirable for regenerative medicine and drug discovery research. Microdroplet surfaces treated with fibronectin, which regulates a variety of cell behaviors through direct interactions with cell surface integrin receptors, were prepared for culturing epithelial cells.

Currently, the development of high-performance adsorbents for the removal of nanoplastics in complex aquatic environments is challenging. In this study, a functionalized polyethyleneimine-phosphorylated microcrystalline cellulose/MoS (PEI-PMCC/MoS) hybrid aerogel was prepared and applied to remove carboxyl-modified polystyrene (PS-COOH) nanoplastics from the aqueous solution. Benefiting from the introduced functional groups and the expanded lamellar structure in MoS nanosheets as well as the highly porous 3D structure of the aerogel, PEI-PMCC/MoS demonstrated high efficiency in PS-COOH nanoplastics removal, achieving a 402.

The recent approval of pembrolizumab in recurrent or metastatic cervical cancer warrants further investigations into the usefulness of immunotherapies for more durable and less radical interventions. In this study, the targeting potential of anti-PD-L1-functionalized immunoliposomes was tested in a 3D in vitro cervical cancer-on-a-chip model. Immunolipsomes were synthesized and decorated externally with monovalent anti-PD-L1 Fab' fragments of commercially available atezolizumab.

This study introduces an innovative electrochemical biosensor, engineered through the functionalization screen-printed electrode (SPE) with a coordination complex comprised of 4-mercaptobenzoic acid (4-MBA) and copper ions (Cu), achieving precise quantitative determination of glyphosate. Electrodepositing gold nanoparticles (AuNPs) onto the electrode surface, forming a self-assembled monolayer (SAM) of 4-MBA via thiol-gold interactions, and immobilizing Cu via coordination bonding with the monolayer, finalizing the electrochemical biosensor construction as Cu/4-MBA/AuNPs/SPE. The successful modification of the biosensor interface is confirmed through scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and electrochemical characterization.
