Sapwood May Filter Bacteria Measuring About 200 Nanometers

If you’ve run out of drinking water during a lakeside camping trip, there’s a simple solution: Break off a branch from the nearest pine tree, peel away the bark, and slowly pour lake water through the stick. The improvised filter should trap any bacteria, producing fresh, uncontaminated water.

Study on Impact of Residual Nano-Silver in the Environment

It is well known that, in the form of free ions, silver particles can be highly toxic to aquatic organisms. Recent research by Eawag and EPFL provides a better understanding about the critical doses and about how the organisms respond to these kinds of stresses.

Marine Sponge Forms Glass Filament with Perfect Periodic Arrangement of Nanopores

Materials made by man and those made by biological organisms often deal with similar synthesis challenges – occasionally converging on an analogous solution independently. One example is the giant glass rod that is used by the sea sponge M. chuni to anchor itself in marine environments.

Epitaxial Mismatches in Ultra-Thin Film Lattices Can Be Used to Tune Energetic Landscape of Mott Materials

"Mottronics" is a term seemingly destined to become familiar to aficionados of electronic gadgets. Named for the Nobel laureate Nevill Francis Mott, Mottronics involve materials – mostly metal oxides - that can be induced to transition between electrically conductive and insulating phases. If these phase transitions can be controlled, Mott materials hold great promise for future transistors and memories that feature higher energy efficiencies and faster switching speeds than today's devices.

Mimicking Behavior of Cells May Help Make Things Work Using Nanoscale Components

Engineers like to make things that work. And if one wants to make something work using nanoscale components—the size of proteins, antibodies, and viruses—mimicking the behavior of cells is a good place to start since cells carry an enormous amount of information in a very tiny packet. As Erik Winfree, professor of computer science, computation and neutral systems, and bioengineering, explains, "I tend to think of cells as really small robots.
