Coating all portions of an extracorporeal membrane oxygenation (ECMO) circuit with materials exhibiting inherent, permanent antithrombotic properties is an essential step to prevent thrombus-induced complications. However, developing antithrombotic coatings for oxygenator fibers within membrane oxygenators of ECMO systems has proven challenging. We have used polydopamine (PDA) to coat oxygenator fibers and immobilize a Cu-based metal-organic framework (MOF) on the surface to act as a nitric oxide (NO) catalyst. Importantly, the PDA/MOF coating will produce NO indefinitely from endogenous -nitrosothiols and it has not previously been applied to ECMO oxygenator fibers.

This study aims at the establishment of a universally applicable etching methodology to unveil the nanoscale crystalline structure of the matrix resin in fiber reinforced thermoplastic (FRTP) composites scanning electron microscopy (SEM). The crystalline structure hierarchically consists of crystalline texture, spherulite and lamella. The details of these structures are key parameters to understand the relationship with the mechanical properties of the material for the advancement.

This study introduces a novel bio-based flame retardant, MCC-GMA-PA-MEL, synthesized from microcrystalline cellulose (MCC) modified with phytic acid (PA) and melamine (MEL). Characterization of the resulting composites revealed a significant enhancement in PLA crystallinity to 35.9 %, driven by improved molecular mobility and heterogeneous nucleation effects.

Fibrinogen nanofiber scaffolds hold promise for tissue engineering and wound healing due to their similarity to fibrin clots. We studied how alkaline salts (Na, K) influence fibrinogen precipitation during drying of highly saline dispersions. In situ roughness (Aq) monitoring revealed coprecipitation of salts and fibrinogen.

The electrochemical urea oxidation reaction (UOR) presents an energy-efficient alternative to the sluggish oxygen evolution reaction (OER), operating at a substantially lower thermodynamic potential and thereby reducing the energy input for hydrogen production by approximately 70%. Simultaneously, UOR facilitates wastewater remediation, offering dual environmental and energy benefits. In this work, we report a MnCO/Ni(OH) heterostructured nanoflower array directly grown on conductive carbon cloth that exhibits outstanding UOR catalytic activity and stability.

Development of efficient and stimuli-responsive gene delivery systems for therapeutic protein expression and immunomodulation remains challenging. Here, we report the synthesis of three types of pH-, reactive oxygen species (ROS)- and glutathione (GSH)-responsive dendrimer nanogels (for short, DNGs-pH, DNGs-ROS, and DNGs-GSH, respectively) a microemulsion method for delivery of messenger RNA (mRNA) and plasmid DNA (pDNA), both encoding enhanced green fluorescent protein (for short, mEGFP and pEGFP), to dendritic cells (DCs). The synthesized DNGs exhibit a nanoscale dimension, high monodispersity, desired colloidal stability, low cytotoxicity, and efficient gene delivery efficiency.
