Nanotechnology for Building Security
Despite increased vigilance and annual federal anti-terrorism spending in excess of $55 billion, building security remains a major concern for most Americans. For those working in large governmental or institutional buildings, fears are particularly acute. [...]
TiO2-Ag Porous Nanocomposites for Advanced Photocatalytic Processes
Baia L., Baia M., Baia L., Baia M., Vasiliu F., Diamandescu L., Peter A., Cosoveanu V., Danciu V., Babes-Bolyai University, RO
The photo-assisted catalytic decomposition of organic pollutants from water and air by employing titanium dioxide as photocatalysts is a very promising method. TiO2 based aerogels are porous solid materials with high surface area, ultra-low density [...]
Silica-alumina composite monoliths with a hierarchical pore structure containing the MFI-type zeolitic films
Pudlo W., Pashkova V., Derewinski M., Jarzebski A.B., Institute of Chemical Engineering, Polish Academy of Sciences, PL
Materials with multimodal hierarchical porosity, containing pore networks in the range of micro-, meso- and macropores, attract considerable attention owing to their widespread application prospects in process industries (catalysts, sorbents), energy conversion and sensors. Here [...]
Optimization of Phage-Based Magnetoelastic Biosensor Performance
A magnetoelastic (ME) platform coated with a bio-molecular recognition element (bacteriophage) for selective and specific recognition of Bacillus anthracis spores is described. ME materials have a mass-sensitive, characteristic, resonant frequency. In response to the binding [...]
Instantaneous Microbial Detection Demonstrated for Air & Water
Traditionally, growth based techniques have been the standard in environmental monitoring for evaluating the quality and quantity of microbial content. However, many studies have underscored the inadequacy of these techniques: (1) to provide environmental microbial [...]
Agent Reactive Modulated Optical Reflector for Hazardous Agent Detection
We demonstrate a standoff passive sensor working in the near infrared range. The device uses a platform based on dielectric and metallo-dielectric layers. The sensor demonstrated a significant change in the reflection coefficient if exposed [...]
Polysilicon Nano-wires Based Nano-device on Silicon Chip: Fabrication and its Application
Mishra N.N., Winterrowd P., Nelson R., Maki G., Maki W.C., Rastogi S.K., Cameron E., Filanoski B., Maki G., Maki W.C., University of Idaho, US
5x5 arrays of six nano-transistor devices were fabricated on p-type silicon/silicon oxide (200nm) wafers with resistivity 1-100 -cm. 50nm of doped polysilicon were deposited and annealed to make nanowires. All nanowires were made with direct [...]
Anodic aluminum oxide-based capacitive humidity sensor integrated with micro-heater
Kim Y.D., Jung B.B., Lee H.K., Lee K.H., Lee H.K., Lee K.H., Park H.C., Pohang University of Science and Technology, KR
AAO(Anodic Aluminum Oxide) film is fabricated as a sensing material of capacitive humidity sensors. Because AAO films have a lot of nano-size pores, many water vapors can be absorbed. The size of a pore diameter [...]
