    A study of the effect of process parameter variation upon the characteristics of screen printed piezoelectric materials

    No full text
    A study of the effect of composition and processing of screen printable piezoelectric materials has been undertaken. Printable pastes of various compositions were produced using a commercially available Lead Zirconate Titanate (PZT) powder mixed with binder and solvents. A range of devices were produced by printing PZT pastes onto alumina (Al_2O_3) substrates. Devices were fired using variations on common thick film processing techniques and poled under varying conditions. Samples were compared by measurement of piezoelectric charge constant, d_3_3 and using scanning electron microscopy techniques. An optimised method for the measurement of d_3_3 was developed. Results show that formulations may be produced that enhance the final value of d_3_3 whilst promoting mechanical strength. Firing temperature, firing time, poling time and poling temperature are all shown to effect the final value of d_3_3 achieved.

    A geomorphological and geotechnical investigation of the Roughlands Landslide Complex, Southwest Isle of Wight, UK

    The Roughlands Landslide Complex, comprised of slumped blocks, minor scarps, debris slides and a wide graben, is one of the few contemporary landslides on the Isle of Wight to be without major geomorphological or geotechnical investigation. Furthermore, Roughlands poses a puzzle as to the origin and form of its basal shear surface. If compound coastal landslides in ancient marine sediments are typically controlled by a basal shear surface which is guided by a bedding parallel slide prone horizon, how is the shear surface accommodated into the ancient fluvial Wessex Formation, which is largely without such bedding features? The complex is hence subject to a thorough investigation. This includes a rigorous desk study, geomorphological survey, peg network monitoring campaign using DGPS, comprehensive geotechnical testing program, and the installation of two slip-indicators. Although largely stable during the summer, parts of the landslide complex are recorded moving at up to 6.5m yr-1 during the wet winter months, indicating a high sensitivity to groundwater variation. Following an appraisal of eight possible formation mechanisms, it is concluded that the basal shear surface which underlies the Roughlands Landslide Complex is most plausibly guided by the basal surface of a Cretaceous sheet flood deposit. Support for this comes from palaeo-environment interpretation, which reveals various mechanisms by which sheet floods could entrain swelling clays; the excessive recession at Roughlands in comparison to other parts of the southwest coastline, which indicates that geological dip (which varies about the Brighstone Anticline) is influential; the fossil record; relationships with newly recognized faults; and from field observations. Stability analyses find field mobilized shear strength is greater than laboratory determined residual shear strength, which may be in part due to entrained Cretaceous floodplain debris within the slide mass. The unpredictability of landslides on the Wessex Formation also identifies some geotechnical uncertainties which are a concern for all engineering works in ancient fluvial sediments

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Get PDF
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
