A planar YBa2Cu3Ox (YBCO) coil has been used as a pick-up coil in a nuclear magnetic resonance imager. It was found that the quality factor (Q) of the YBCO coil was greater than its copper counterpart by approaching 50% even in a field of 0.15 T. The Q of the copper coil at 77 K and in a field of 0.15 T was 1200 while that of the YBCO coil under identical(More)
BACKGROUND Image-guided surgery has become standard practice during surgical resection, using preoperative magnetic resonance imaging. Intraoperative ultrasound (IoUS) has attracted interest because of its perceived safety, portability, and real-time imaging. This report is a meta-analysis of intraoperative ultrasound in gliomas. METHODS Critical(More)
This paper reports low-temperature sintering methods for the (Ba<sub>0.85</sub>Ca<sub>0.15</sub>)(Zr<sub>0.1</sub>Ti<sub>0.9</sub>)O<sub>3</sub> (50BCZT) ceramics and thick-films. A commercial borosilicate glass and Li<sub>2</sub>O have been investigated as sintering aids. Bulk ceramic samples with 1 wt% borosilicate glass and sintered at 1200&#x00B0;C(More)
This paper reports the fabrication and characterization of a free-standing piezoelectric thick-film structure: single-layer films and multi-layer cantilevers, for the application of vibrational energy harvesting. Piezoelectric properties without constraint effect are properly characterized. The single-layer thick-films exhibit d31 values of approximately(More)
This paper reports an investigation of (Ba<sub>0.85</sub>Ca<sub>0.15</sub>)(Zr<sub>0.1</sub>Ti<sub>0.9</sub>)O<sub>3</sub> (50BCZT) piezoelectric ceramics doped with Bi<sub>0.5</sub>(Na<sub>0.82</sub>K<sub>0.18</sub>)<sub>0.5</sub>TiO<sub>3</sub> (18BNKT). For compositions between 1-5 wt% 18BNKT, a perovskite phase was observed in the sintered ceramics,(More)
