Penn State researchers have developed the first powder injection molding process for pure niobium, a biocompatible material similar to platinum and titanium but cheaper.
The researchers, who are based in the Universitys Center for Innovative Sintered Products, say the new process could open the door to injection-molded niobium parts ranging from rocket nozzles, to wires, to human bone replacements, to orthodontic braces.
Gaurav Aggarwal, doctoral candidate in engineering science and mechanics, will present the teams work in a paper, Development of Niobium Powder Injection Molding, at the International Symposium on Tantalum and Niobium in Pattaya, Thailand, Oct. 17. His co-authors are Seong J. Park, research associate in engineering science and mechanics, and Dr. Ivi Smid, associate professor of engineering science and mechanics, who is Aggarwals thesis adviser.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
