Silver nanoparticle synthesis using strawberry tree leaf

(PhysOrg.com) -- Anyone who thinks amalgams are limited to tooth fillings is missing something: Amalgams, which are alloys of mercury and other metals, have been used for over 2500 years in the production ...

They might just be the smallest Christmas tree decorations ever. Tiny spherical particles of gold and silver that are more than 100 million times smaller than the gold and silver baubles used to decorate seasonal fir trees ...

Food waste is a growing problem in many parts of the world, but discarded fruit peel, in the case of pomegranates, could be put to good use in the burgeoning field of nanotechnology according to research published in the ...

Nanoparticles of silver are being found increasingly in the environment—and in environmental science laboratories. Because they have a variety of useful properties, especially as antibacterial and antifungal ...

Writing in the International Journal of Nanoparticles, Rani Pattabi and colleagues at Mangalore University, explain how blasting silver nitrate solution with an electron beam can generate nanoparticles that are more effect ...

Porous ceramic water filters are often coated with colloidal silver, which prevents the growth of microbes trapped in the micro- and nano-scale pores of the filter. Other metals such as copper and zinc have also been shown ...

(Phys.org) —Imagine a bendable tablet computer or an electronic newspaper that could fold to fit in a pocket.

These days, aerospace engineering is all about the light stuff: building airplanes with lighter wings, fuselage and landing gear in an effort to reduce fuel costs.

One of the basic principles of nanotechnology is that when you make things extremely small—one nanometer is about five atoms wide, 100,000 times smaller than the diameter of a human hair—they are going ...

Nearly everyone is familiar with the polytetrafluoroethylene (PTFE), otherwise known as Teflon, the brand name used by the chemical company DuPont. Famous for being "non-sticky" and water repellent, PTFE is a dry lubricant ...

Frustration led to revelation when Rice University scientists determined how graphene might be made useful for high-capacity batteries.

Scientists have identified nanostructures in the ultra-black skin markings of an African viper which they said Thursday could inspire the quest to create the ultimate light-absorbing material.
