OU Researchers Develop Novel, Non-Invasive Cancer Therapy Using Targeted Single-Walled Carbon Nanotubes

A staggering 1.7 million persons in the United States will be diagnosed with cancer in 2016, with 600,000 cases ending in death. University of Oklahoma researchers have collaborated to design a novel, non-invasive cancer therapy that could eliminate tumors without affecting the healthy cells in the body.

Nanowires as Sensors in New Type of Atomic Force Microscope

poggio_nanowire_2016_big.jpg

A new type of atomic force microscope (AFM) uses nanowires as tiny sensors. Unlike standard AFM, the device with a nanowire sensor enables measurements of both the size and direction of forces. Physicists at the University of Basel and at the EPF Lausanne have described these results in the recent issue of Nature Nanotechnology.

Electrons in Graphene Behave Like Light, Only Better

Fig1negativerefraction.png

Researchers have directly observed—for the first time—negative refraction for electrons passing across a boundary between two regions in a conducting material. They observed the effect in graphene, demonstrating that electrons in the material behave like light rays, which can be manipulated by such optical devices as lenses and prisms. The findings could lead to the development of new types of electron switches, based on the principles of optics rather than electronics. (Science 9/30)

Promising Biomaterial to Build Better Bones with 3-D Printing

Shah-3-D-printed-bonefemur.jpg

A Northwestern University research team has developed a 3-D printable ink that produces a synthetic bone implant that rapidly induces bone regeneration and growth. This hyperelastic “bone” material, whose shape can be easily customized, one day could be especially useful for the treatment of bone defects in children. Antibiotics also can be incorporated into the ink to reduce infection. The printed biomaterial’s many unique properties set it apart from current bone repair materials.

Crystalline Fault Lines Provide Pathway for Solar Cell Current

A team of scientists studying solar cells made from cadmium telluride, a promising alternative to silicon, has discovered that microscopic "fault lines" within and between crystals of the material act as conductive pathways that ease the flow of electric current. This research-conducted at the University of Connecticut and the U.S. Department of Energy's Brookhaven National Laboratory, and described in the journal Nature Energy-may help explain how a common processing technique turns cadmium telluride into an excellent material for transforming sunlight into electricity, and suggests a strategy for engineering more efficient solar devices that surpass the performance of silicon.
