Satisfactory restoration in a patient with a partially edentulous situation can be challenging especially when unilateral or bilateral posterior segment of teeth is missing. Successful restoration can be done with various conventional and contemporary treatment options. One such treatment modality is attachment-retained cast partial dentures. A key to success for an attachment retained cast par...

Niobium-alumina composite aggregates with 60 vol% metal content and particle sizes up to 3150 μm are produced using castable technology followed by sintering, a crushing sieving process. X-Ray diffraction (XRD) analysis reveals phase separation during as the niobium:corundum volume ratios is between 37:57 64:31 among 4 aggregate classes 0–45, 45–500, 500–1000, 1000–3150 μm. The synthesized used...

The preparation and characterization of the cocrystalline solid-organic sodium ion electrolyte NaClO4 (DMF)3 (DMF=dimethylformamide) is described. The crystal structure of NaClO4 (DMF)3 reveals parallel channels of Na+ and ClO4- ions. Pressed pellets of microcrystalline NaClO4 (DMF)3 exhibit a conductivity of 3×10-4  S cm-1 at room temperature with a low activation barrier to conduction of 25 k...

Buckypaper are self-supporting films of carbon nanotubes (CNT), which can be used as electrodes, nano filter or for the reinforcement of polymers, for instance. Usually they are produced by filtration of CNT dispersions. The disadvantages of filtration process are discontinuous operation, long duration of filtration and limited size of the buckypaper. The aim of this project was to develop a sp...

We introduce a novel large-scale Digital Construction Platform (DCP) for on-site sensing, analysis, and fabrication. The DCP is an inprogress research project consisting of a compound robotic arm system comprised of a 5-axis Altec hydraulic mobile boom arm attached to a 6-axis KUKA robotic arm. Akin to the biological model of human shoulder and hand this compound system utilizes the large boom ...
