Nguyen A.T., Nguyen H.V., Nguyen K.C., Nguyen T.N.T., Nguyen A.T., Nguyen H.V., Nguyen K.C., Nguyen T.N.T., Do S.T., Doan T.T., Doan T.T., Nguyen A.T., Nguyen H.V., Nguyen K.C., Nguyen T.N.T., Le T.V., Nguyen A.T., Nguyen H.V., Nguyen K.C., Nguyen T.N.T., SAIGON HI TECH PARK, VN
In the present study, we reported a novel type of proton transport material comprised of “liquid” nano carbon (2) embedded in a polymer matrix to form proton conducting nanocomposit. The nanocomposit exhibits excellent proton transport [...]
A Revolutionary New Method for the Synthesis of a Wide Array of Metal Oxide and Mixed Metal Oxide Nanoparticles with Sizes as Small as 1 nm
Woodfield B.F., Liu Q., Liu S., Liu Q., Liu S., Astle L., Boerio-Goates J., Brigham Young University, US
We have developed a revolutionary new method for the production of large quantities of high-purity metal, metal oxide, and mixed-metal oxide nanoparticles. Particles are uniform in size with dimensions that can range from 1 nm [...]
Nanoporous Silicon Membrane Based Micro Fuel Cells for Portable Power Sources Applications
In this paper the formation of nanoporous silicon membranes and evaluation of their usage for the solid electrolyte in miniature direct formic acid fuel cells compatible with silicon micro-fabrication technology is reported. Nanoporous silicon membranes [...]
Ultra-thin Nanocomposite Membranes for Highly Sensitive Sensors
Highly sensitive sensor arrays are critical for prospective devices and demanded for various applications. Measuring microscopic deflections with sensitive membranes is one of the most versatile approaches for pressure, acoustic, chemical and biomolecular sensing. Here [...]
Pt and Pt-Ru/Carbon Nanotube Nanocomposites Synthesized in Supercritical Fluid as Electrocatalysts for Low-Temperature Fuel Cells
In recent years, the use of supercritical fluids (SCFs) for the synthesis and processing of nanomaterials has proven to be a rapid, direct, and clean approach to develop nanomaterials and nanocomposites. The application of supercritical [...]
Noncovalent Catenation between Metal-Ligand Coordination Macrocycles and _-Cyclodextrin
Here we describe our findings on the facile preparation of first [2]catenanes from metal-ligand coordination macrocycles and b-CD ring. The [2]catenane formation is illustrated in Figure 1. Coordination between a divalent ligand and Pd(II) spontaneously [...]
TiN/GaN- Metal/Semiconductor Multilayers for Thermionic Energy Conversion Devices
This work deals with investigation of metal/semiconductor nitrides for potential application as solid state thermionic energy converters. TiN/GaN multilayers were deposited on Sapphire and MgO substrate using reactive pulsed laser deposition. This is the first [...]
Fracture of Vacancy-defected Carbon Nanotubes and Their Embedded Composites
In this paper, we investigate the effects of vacancy defects on the fracture of carbon nanotubes and carbon nanotube/aluminum composites. Our studies show that even a one-atom vacancy defect can dramatically reduce the failure stresses [...]
