- L1.5 Michael D. Morris, Molecular Response of Bone Matrix Collagen and Bone Mineral to Mechanical Loading.— A Raman Spectroscopic Study
Tuesday, 9:45AM—Room 3004, Moscone West
One of the tough questions in bone biomechanics is how bone as a nanocomposite deforms at molecular level. This paper demonstrates that bone deformation causes changes to the structural parameters in collagen and bone minerals and these changes could be detected (for the first time) by Raman spectroscopy.
- L2.2/K2.2 Anthony Evans, Mechanisms Governing the Inelastic Deformation of Bone
Tuesday, 2PM—Room 3002, Moscone West
The fact that bone is tough is because of its nanocomposite nature and its capability of undergoing inelastic deformation. However, establishing a theoretical model to relate the nanostructure to the inelastic deformation has been a challenge. This study seeks to solve the problem through the extensive lessons we have learned from synthetic materials.
- L4.1 Xiaodong Li, AFM Imaging and Nanomechanical Testing of Cells and Tissues

SYMPOSIUM R
Nanoporous and Nanostructured Materials for Catalysis, Sensor and Gas Separation Applications
View Program | View Abstracts
- R2.5 Dominik Kramer, Reversible Strain in Porous Metals Charged in Electrolytes
Monday, 4:15PM—Room 3001, Moscone West
The results shown are experimental evidence that the strain in a metal can be reversibly changed by charging the nanoporous sample in an electrolyte. This suggests that porous metals can be used as “metallic muscles”— novel actuator materials that are compatible with biological environment.
- R6.3 Zhong L. Wang, Oxide Nanobelts for Electromechanical Coupled Nanosensors
Wednesday, 8:30AM—Room 3001, Moscone West
In the presentation, the author will describe oxide nanobelts which are pure, structurally uniform, single crystalline and most of them free from defects and dislocations. The nanobelts have widths of 10-60 nanometers and thickness of 5-20 nanometers, and they are free of dislocations. The belt-like morphology appears to be a unique and common structural characteristic for the family of semiconducting oxides with cations of different valence states and materials of distinct crystallographic structures. The nanobelts are an ideal system for fully understanding dimensionally confined transport phenomena in functional oxides and building functional devices along individual nanobelts. These nanobelt materials have developed into devices like single-wire sensors.
- R7.1 Ray H. Baughman, Giant Double-Layer Charge Injection without Contacting Electrolyte— Properties Tuning and Device Applications
Wednesday, 1:30PM—Room 3001, Moscone West
The authors report a surprising generic method for charge‑injection‑based tuning of the bulk properties of electrolyte‑free nanostructured materials over a wide range without incurring dopant intercalation and associated problematic structural changes. Specifically, they report that carbon nanotube sheets, nanoporous metals, and other nanostructured materials retain injected charge and associated structure and properties changes when charged in a liquid‑electrolyte and then removed from the electrolyte and dried in vacuum. These discoveries are of importance for devices.
- R7.6 Peidong Yang, Inorganic Nanotube-Based Ionic Transistors
Wednesday, 3:15PM—Room 3001, Moscone West
The authors report a nanofluidic transistor, a three-terminal device with a gate electrode, that exploits a novel effect, solution confinement, uses it for electrostatic control of ionic and molecular transport in nanofluidic channels. This effect is similar to the field effect modulation of electrons and holes in a metal-oxide-semiconductor (MOS) transistor. Furthermore, these nanotube transistors provide a novel platform for probing and electrostatic manipulation of the chain dynamics of single DNA molecules within nanochannels. The results illustrate the efficacy of field-effect control in nanofluidics, which would have broad implications on integrated nanofluidic circuits for manipulation of ions and biomolecules in femtoliter volumes.
R10.1 Yuri Gogotsi, Carbide-Derived Carbon with Tunable Pore Size
Thursday, 1:30PM—Room 3001, Moscone West
The presentation describes a novel approach to synthesize carbide-derived nanoporous carbon with tunable pore size sub-Angström accuracy in the 0.5-2nm range. The structure of the carbon is controlled by the structure of the carbide precursor as well as process parameters including temperature, time and environment. The carbide-derived carbons (CDC) with a narrow pore size distribution and a large pore volume of 50-80% can be used for gas storage, separation, catalysis and other applications.

This paper relates to the specific application of ultrananocrystalline diamond (UNCD) as a coating for encapsulation of a microchip implantable in the human eye to restore sight to people blinded by retina degeneration. UNCD can enable the implantation of the microchip in the human eye. This work is part of a large program funded by DOE, involving five national laboratories, three universities, and one company (Second Sight, which will market the artificial retina) to develop an artificial retina to restore sight to people blinded by retina degeneration. In this program there are already two people on clinical trial (one man and one woman) who have been blind for about 50 years and have first-generation implanted devices that allow them to distinguish light from darkness and distinguish shapes of objects. Movies of the patients undergoing vision tests may be available for viewing.
