We have developed a new nanochannel fabrication technique using chemical-mechanical polishing (CMP) and thermal oxidation. With this technique, it is possible to control the width, length, and depth of the nanochannels without the need for nanolithography. The use of sacrificial SiO2 layers allows the fabrication of centimeter-long nanochannels. In addition, the fabrication process is CMOS comp...

Gelatin is considered as a partially degraded product of collagen and it is a biodegradable polymer which can be used to produce scaffolds for tissue engineering. Three-dimensional, porous gelatin scaffolds were fabricated by thermally induced phase separation and freeze-drying method. Their porous structure and pore size were characterized by scanning electron microscopy. Scaffolds with differ...

rehabilitation of facial defects is a complex task, requiring an individualized design of the technique for each patient. the disfigurement associated with the loss of an eye may result in significant physical and emotional problems. various treatment modalities are available, one of which is the use of implants. although implant-supported orbital prosthesis has a superior outcome, it may not b...

by Eric W. Johnson With the development of improved fabrication processes, more responsibility is placed on circuit designers to develop circuits that are tolerant of fluctuations in the fabrication process. To achieve this higher reliability, designers must have access to actual data variations in the fabrication process. Historically, this process data has been collected from test measurement...

The present article introduces a new technique for chairside provisional fixed partial dentures fabrication. The described direct technique is suitable for a fast and relatively easy fabrication of provisional single crowns or small bridges. It does not necessitate any preliminary laboratory stages (such as wax-up e.g.) but rather tends to adapt the teeth morphology of a selected model to the s...

The Engineering and Fabrication Branch of the Technical Services Department provides a wide range of engineering, design, and fabrication services for the Applied Physics Laboratory. The Branch routinely practices a technique known as "statistical process control" in the design, fabrication, testing, calibration, and quality control phases of its work to ensure the quality of designed and fabri...
