Aerosol filtration performance of nanofibrous mats produced via electrically assisted industrial-scale solution blowin
(Wiley, 2021)Highly efficient polyamide 6 (PA6)-based nanofibrous air filter media was developed for particulate matter (PM) removal in the ambient atmosphere. The PA6 nanofibrous mats exhibited 85% PM0.3 capture performance at a cost ... -
Geopolymerization mechanism of binder-free mine tailings by sodium silicate
(Elsevier Ltd, 2021)The geopolymerization of solid substances rich in calcium and aluminum including mine tailings by sodium silicate is mainly believed to be under the influence of alkali activation. However, mine tailings’ relative neutral ... -
Developing centrifugal spun thermally cross-linked gelatin based fibrous biomats for antibacterial wound dressing applications
(Wiley, 2021)Fibrous materials obtained from natural polymers, such as gelatin, have been used in medical applications due to their biocompatibility and biodegradability. Herein, free-standing durable fibrous gelatin biomats with ... -
