Ethyl cellulose (EC) is a biocompatible, renewable, and recyclable material with diverse sources, making it an attractive candidate for industrial applications. Electrospinning has gained significant attention the production of EC fibers. However, conventional electrospinning methods face challenges such as bead formation, low yield, absence porous internal structures, limiting both functional performance scalability. This study presents optimized approach producing fibers by using gravity-driven ultrahigh-speed (GUHS-ES) system. system leverages gravity to reshape Taylor cone morphology during electrospinning, enhancing stability dramatically increasing throughput. As flow rates increase, contracts inward, while tip structure expands stabilizes, reaching maximum size at ultrahigh (100–150 mL/h). unique enables fiber rate 24.5 g/h, hundreds times greater than techniques. Another advantage GUHS-ES its ability achieve high diameter uniformity adjustable porosity. At rates, pore sizes reached 321 nm. The highly exhibited absorption capacity 56.6 110.7 their weight, exceeding most previously reported oil-absorbing materials demonstrating efficacy rapid waste oil absorption. green, efficient technology represents promising advancement large-scale application natural polymer broad implications sustainable processes.

Pulmonary fibrosis (PF) is a progressive interstitial lung disease characterized by excessive extracellular matrix deposition and tissue scarring, leading to impaired function respiratory failure. Although current treatments, such as pirfenidone nintedanib, slow progression, they fail completely halt or reverse fibrosis. Therefore, innovative therapeutic strategies are needed. Targeted drug delivery systems (TDDSs) emerging promising solutions. Biomaterials play critical roles in these enhancing specificity, availability, efficacy, while minimizing systemic toxicity. The most notable biomaterials include nanotechnology-based systems, including liposomes polymeric nanoparticles, which facilitate penetration release fibrotic tissues. Hydrogels have three-dimensional structures providing controlled sustained at inflammation sites, therefore particularly valuable PF treatment.
