Materials Sciences

Materials management deals with the research, development, manufacturing and processing of raw and industrial materials. Key aspects here are biological and medical issues, which play an increasingly important role in this field.

innovations-report offers in-depth articles related to the development and application of materials and the structure and properties of new materials.

Nano-scale trees created at Lund Institute of Technology

For the last few years scientists at the Nanometer Consortium at Lund University have been able to make nanowires, tiny wires just a few millionths of a millimeter “thick” and made of semiconducting material of great potential in the electronics industry. Now they have managed to produce “nanotrees,” in fact tiny forests on the same scale.

This is described in an article (“Synthesis of branched ‘nanotrees’ by controlled seeding of multiple branching events”) in the journal Nature Materials,

Laser technique used to build micro-polymeric structure on a human hair, without harming it

First demonstration that ’MAP’ laser technique can be used non-destructively on biomaterials; potential applications range from medical research to fiber optics

Researchers in the laboratory of Boston College Chemistry Professor John T. Fourkas have demonstrated the fabrication of microscopic polymeric structures on top of a human hair.

Fourkas, in collaboration with Boston College Physics Professor Michael J. Naughton and Professors Malvin C. Teich and Bahaa E. A.

A Conveyor Belt for the Nano-Age

In a development that brings the promise of mass production to nanoscale devices, Lawrence Berkeley National Laboratory scientists have transformed carbon nanotubes into conveyor belts capable of ferrying atom-sized particles to microscopic worksites.

By applying a small electrical current to a carbon nanotube, they moved indium particles along the tube like auto parts on an assembly line. Their research, described in the April 29 issue of Nature, lays the groundwork for the high-throughput

NJIT grad student and professor take ride of their lives in vomit comet

Actually, doctoral candidate Alexandre Ermoline, North Arlington, NJ and NJIT Assistant Research Professor Mirko Schoenitz , PhD, Princeton, NJ, took four rides over four days aboard a KC-135 aircraft operated by the National Aeronautics and Space Administration (NASA). NASA operates the craft at the Lyndon B. Johnson Space Center in Houston which advances research in microgravity.

“Moving without gravity is an unusual sensation,” recently recalled Schoenitz. “I’ve heard people describ

Nanogold does not glitter, but its future looks bright

At the nano-level, gold acquires a new shine, a new set of properties and a host of potential new applications

All that glitters is not gold, goes the old adage.

But the shrinking frontiers of science require a qualifier: Gold itself does not always glitter.

In fact, if gold is created in small enough chunks, it turns red, blue, yellow and other colors, says Chris Kiely, who directs the new Nanocharacterization Laboratory in Lehigh’s Center for Advanced Materi

Wet scans

The “scanning electron microscope” (SEM) has been a basic research tool for fifty years, and for those fifty years, scientists have been looking for better ways to observe biological samples under its beam. The problem is that the viewing chamber of the SEM must contain a vacuum (in which liquid water in tissues “boils” away). To overcome this difficulty, scientists have had to resort to all sorts of complicated procedures, including coating the specimens with an ultra-fine layer of gold, quick-freez
