摘要:
This invention provides novel fuel cell catalysts comprising new series of catalytically active thin-film metal alloys with low platinum concentration supported on nanostructured materials (nanoparticles). In certain embodiments, an integrated gas-diffusion/electrode/catalyst layer can be prepared by processing catalyst thin films and nanoparticales into gas-diffusion media such as Toray or SGL carbon fiber papers. The catalysts can be placed in contact with an electrolyte membrane for PEM fuel cell applications.

Mechanical stresses and deformations are applied directly to cell surface receptors or molecules and measured using a system including a magnetic twisting device in combination with ferromagnetic microbeads coated with ligands for integrins or any other surface receptors. The system can be used diagnostically to characterize cells and molecules and to determine the effect of transformation and compounds, including drugs, on the cells and molecules. The system can also be used to induce cells to grow or alter production of molecules by the cells.

A method of packet processing includes receiving a packet at one of a plurality of network ports at a switch device, tagging the packet with a first identification, tagging the packet with a second identification, using a first table to determine a first set of output port identifications based at least in part on the first identification, using a second table to determine a second set of output port identifications based at least in part on the second identification, and performing a logical operation using the first set of output port identifications and the second set of output port identifications to identify one or more of a plurality of output ports at the switch device.
摘要:
A rapid response relative humidity sensor based on nano-structured aluminum oxide thin film is disclosed. The main body of the sensor is an anodic aluminum oxide thin film of about 2-20 μm thick formed from an Al substrate which serves as one electrode. A porous metal layer of about 20-200 nm thick is formed over the anodic aluminum oxide thin film and functions as a second electrode. The alumina thin film contains nano-sized channels of about 10-100 nm in diameter, serving as a capacitive relative humidity sensor having high sensitivity and short response time. Thermal annealing at elevated temperature improves the linearity of the capacitance versus humidity curve, giving a full range humidity sensing range. Hysteresis and degradation are negligible for the humidity sensors.
