Enriching Inlet
THE CHALLENGE More than 99.9999% of air is comprised of gases that are not chemically reactive (e.g., nitrogen, oxygen, carbon dioxide), even in polluted regions. The remaining <0.0001% of air includes all the components that form what we typically think of as air pollution (toxic odors, particulate matter, ozone, etc.). Due to these extremely low...

A Broad-spectrum Biopesticide Strain with Plant Growth Promoting Capability
The Challenge Plant diseases can wipe out entire crops and historical plantings in a short period of time as shown by boxwood blight. Globally, these diseases pose increasing risks to food security and plant biosecurity. Current approaches to disease management depend largely on chemical protection. These approaches are not sustainable due to growing...

Ocean Wave Energy Harvester Using Mechanical Modified Rectifier
The novel power take off (PTO) technology transforms the back-and-forth wave movement into a single-directional movement to more efficiently capture wave energy using the creative design of ball screw and one-way bearing. The new PTO will improve energy conversion efficiency and reliability with a very compact design, which solves the fundamental challenge...

F2mc Power Take-Off Pumps For Wave Energy Conversion
Virginia Tech's f2mc power take-off pumps convert energy from ocean waves in hydraulic energy using fluidic flexible matrix composite tube pumps. F2mc tubes consist of stiff reinforcing fibers embedded in a soft elastomer or polymer matrix. When a load is applied to the tubes, the volume of the composite pump is reduced and fluid is forced out of the...

3D Nanoparticle/Bacterial Cellulose Nanocomposite for Analyte Detection
The low affinity of many analytes to noble metal surfaces often limits their capacity to be detected by surface enhanced Raman spectroscopy (SERS). To enhance surface affinity and improve reproducibility we have produced a nanocomposite consisting of a bacterial cellulose support matrix that is embedded with either gold or silver nanoparticles. By restraining...

Noise Reducing Surface Treatment for Airfoil
This innovative design comprises a surface treatment on airfoils that reduces trailing edge noise. Existing measurements suggest noise reduction by as much as 15dB. Most present designs to mitigate trailing edge noise involve changing the shape of the airfoil trailing edge. However, this technology utilizes a novel surface treatment to attenuate boundary...

Functionalized Metal Oxides As A Stationary Phase And A Surface Template For Micro Gas Chromatography Separation Columns
This invention describes a new approach for utilizing atomic layer deposited (ALD) metal oxides as a stationary phase for microfabricated gas chromatography columns. After ALD oxide deposition, a chloroalkylsilane is utilized to deactivate the oxide surface to improve peak symmetry and retention times. Semipacked columns (1m-long, 190 um-wide with 20...
