Researchers discover nanocrystals able to squeeze through nanotubes without changing

(Phys.org) —Researchers at the University of California, Berkeley, have discovered that a nanocrystal moving through a nanotube due to an electric charge is able to pass through a portion of the nanotube that is smaller in diameter than the crystal, without melting or undergoing compression. In their paper published in the journal Physical Review Letters, the team describes how they observed an iron nanocrystal move through a narrow channel in a nanotube without its properties being changed in the process.

Reducing arsenic in food chain: Soil may harbor answer to reducing arsenic in rice

Harsh Bais and Janine Sherrier of the University of Delaware’s Department of Plant and Soil Sciences are studying whether a naturally occurring soil bacterium, referred to as UD1023 because it was first characterized at the University, can create an iron barrier in rice roots that reduces arsenic uptake.

Researchers develop 'smart' paper and antennaless RFID tags

Research teams at North Dakota State University, Fargo, have developed a method to embed radio frequency identification (RFID) tags in paper, which could help combat document counterfeiting, and have developed antennaless RFID tags for use on metal. Both teams of researchers are presenting their technology advances at conferences from April 30 to May 2 in Orlando, Fla. Dr. Val Marinov will present research at RFID Journal LIVE! and Cherish Bauer-Reich and Layne Berge are presenting at the Institute of Electrical and Electronics Engineers (IEEE) International Conference on RFID, highlighting the NDSU technology breakthroughs.

The search is over: Internet content is looking for you

Where you are and what you’re doing increasingly play key roles in how you search the Internet. In fact, your search may just conduct itself. This concept, called “contextual search,” is improving so gradually the changes often go unnoticed, and we may soon forget what the world was like without it, according to Brian Proffitt, a technology expert and adjunct instructor of management in the University of Notre Dame’s Mendoza College of Business.
