Reactive spinning of nano- and microfibers that involves very fast chemical reactions and ion exchange is a challenge for the common methods for nanofiber formation. Herein, we introduce the reactive magnetospinning method. This procedure is based on the magnetic-field-directed collision of ferrofluid droplets with liquid droplets that contain complementary reactants. The collision, start of th...
Due to significant environmental advantages, biocomposites have recently received increasing attention. In the present research, strength of hat-shaped coir fiber biocomposites tubes reinforced with nano powder was evaluated experimentally under 3-point bending tests. The tubes were manufactured using hand lay-up technique and based on Taguchi design of experiment. The effects of different para...
Chronic and non-healing wounds show delayed incomplete healing process, which expose the patients to a high risk of infection. These types require frequent change dressing, is burden on patients. In addition, ideal dressing needs meet requirements in minimizing microbial infiltration growth while balancing moisture exchanging oxygen with outside environment. To overcome challenge design require...
Carbon nanotube (CNT)-based materials allow for the direct conversion of light into heat and then mechanical force in so-called photo-mechanical effect. This effect has been observed almost solely form polymer (nano)composites, where CNTs act as active fillers. To overcome issue with heterogeneous distribution, hybrids based on multiwalled carbon nanotubes (MWCNTs) covalently modified poly(2-hy...
Dependence of electrochemical properties of vanadium oxide films on their nano- and microstructures.
Platelet- and fibrillar-structured V2O5 films have been prepared by solution methods, and their electrochemical Li+ intercalation properties have been studied. Platelet film consists of 20-30 nm sized V2O5 particles with random orientation, whereas fibrillar film is comprised of randomly oriented fibers though most of them protrude from the substrate surface. These platelet- and fibrillar-struc...
Background & Aims of the Study: Soil and water pollution to heavy metals is a serious threat for environment and human health. Finding an effective way for refining water from these metals is very important. The aim of this study was modifying electrospun polymeric nano fibers and studying its efficiency for copper ion omission in water solutions. Materials & Method...
Composite fibrous membranes based on poly(ɛ-caprolactone) (PCL) and mesoporous bioactive glass nanoparticles (MBGNs) were fabricated by electrospinning. MBGNs Zn-doped prepared microemulsion sol–gel method successfully incorporated inside the polymeric fibers of 240 385 nm in diameter for undoped PCL_MBGNs fibers, respectively. Thermal analysis showed that concentration reached a maximum around...
