Focused Ion Beam Fabrication of Fiber Probes for Use in Near-Field Scanning Optical Microscopy
Published Tuesday, March 9, 1999A new focused ion-beam (FIB) fabrication method has been developed to produce very clean, well-defined and highly reproducible sub-wavelength fiber probes with metallic apertures of a desired diameter for use in near-field scanning optical microscopy (NSOM). The ion beam milling process can eliminate the obstruction of apertures caused by...

Electric Walk-Through Fly Trap for the control of Face, Stable, and Horn Flies
Published Wednesday, March 24, 1999Horn, stable and face flies pose a complex and expensive pest problem for cattle ranchers. Economic losses due to fly infestations results from reduction in weight gain by the cattle, depression in levels of milk production, pest control expenses including labor and lawsuits filed by the surrounding community. In the United States these losses...

Scanning Single Electron Transistor Microscope for Imaging Room Temperature Objects
Published Monday, April 5, 1999The occurrence of wiring defects in computer chips and multi-chip modules is a serious manufacturing problem. Most types of circuit faults can only be localized to more-or less definite regions on a chip simply because they produce failures in a region of the circuit. However, if the circuit defect could be precisely located, then the likely cause...

LifeLines for Visualizing History Records
Published Monday, April 5, 1999Records of personal histories are needed in a variety of applications. Members of the medical and legal professions examine a record to garner information that will allow them to make an informed decision regarding their patient or case. Decision making critically depends on gleaning the complete story, spotting trends, noting critical incidents...

Continuous Particle Separation
Published Monday, April 12, 1999Separation of biological particles - specifically separation of Polyhedral Inclusion Bodies (PIBs) - from tissue and debris associated with production of virus using insect hosts, is a very difficult procedure. Typically separation is not accomplished. Instead the host insect is processed in its entirety leading to a very impure and diluted final...
