Nano-style sheets may aid health, shield ecosystem

Microscopically, “nanomembrane” sheets made from nylon resemble a tangled web. The tiny iron oxide particles on the fiber surfaces can help clean toxic chemicals from water, but if the particles get separated from the web, they can become hazards themselves. In a new study, Cornell researchers examined these special nylon sheets – replete with applied...

A biodegradable nanogenerator made with DNA

Long-standing concerns about portable electronics include the devices' short battery life and their contribution to e-waste. One group of scientists is now working on a way to address both of these seeming unrelated issues at the same time. They report in the journal ("DNA-Assisted β-phase Nucleation and Alignment of Molecular Dipoles in PVDF Film:...

Producing nanofibers with controlled size

Researchers studied the effective parameters on the production of polymeric nanofibers through electrospinning method ("Effect of electrospinning process parameters of polycaprolactone and nanohydroxyapatite nanocomposite nanofibers"). Nanofibers with desirable diameter and size can be produced using...
