A silk fibroin based green nano-filter for air filtration 2021-03-31

We report the silk fibroin nanofiber air filter. The inherent properties of silk fibroin play a key role in improving filtration performance. And because of the biodegradability of silk fibroin, the film is disposable after use. The methods and results presented here can provide a novel perspective for air filtration; pave the way for the production of safe and clean air filtration systems.

Fabrication of polycaprolactone electrospun fibers with different hierarchical structures mimicking collagen fibrils for tissue engineering scaffolds 2021-03-31

Both of these nanostructures improve cell viability and proliferation. In addition, this porous surface facilitates enhanced cellular response. This shows that it has the potential and biocompatibility to mimic collagen fibrils, and is used in tissue engineering, especially as a scaffold for the endothelial layer of blood vessels.

Electrospun nanofibre materials to filter air pollutants - A review 2021-03-30

The overview of electrospun nanomembranes produced by various polymers for filtering air pollutants is introduced. The characteristics of nanofibers that affect filtration efficiency are discussed.

Electrospun nanomaterial offers great protection against electromagnetic interference 2023-04-08

Engineers have employed "electrospinning," a new technique of manufacturing nanomaterials, to produce a novel fabric that offers high performance protection against electromagnetic interference, a phenomenon that can result in electronic device malfunction and at high levels of exposure can harm human health

An Introduction to ElectroSpinning and NanoFibers 2023-04-11

Electrospinning is a process that involves the following: An inherently complex, multi-component material such as the polymer solution A fluidic and electrical equipment often including needles, syringes, and motorized elements for careful control of flow rates and generators providing high voltages The environment external to the process, which may range from air atmosphere to closed chambers operating with controlled gases or in stabilized temperature, vacuum conditions, etc. An automatic syringe pump is used to pump the fluid through a syringe. A voltage is supplied (using several kV potential) to positively charge the syringe needle. As shown in the below images, the resulting electric field causes fibers to be pulled out of the droplet at the end of the syringe tip and onto a grounded metal collector.

Electrospinning to Produce Polymer Based Nanofibers 2023-04-17

Polymer-based nanofibers are produced using a process called electrospinning. In this process, the polymer material (sometimes a polymer melt) is electrically charged and then subjected to an applied electrical field where the polymeric material is removed and 'whipped' from the source in fine 'needle-like' structures to form nanofibers.
