This paper describes recent work by the authors on a continuum model for crystal twinning. Twinning is described as an anti-plane shear deformation with discontinuous strains, governed by an elastic potential with multiple wells. Possible shapes of twin lamellae and twinning steps and various regimes of their steady d…
A new ionic liquid crystal system, based on compounds with the viologen group (for example, 1–2: Cr 190 SA 280 dec.) has been synthesized, and is found to exhibit the smectic A phase.
Two sol‐gel routes have been used to prepare celsian (BaAl 2 Si 2 O 8 ) precursors. The crystallization behaviors of unseeded gels and the gels seeded with 5 wt% feldspar, rutile, LiAISi 2 O 2 , and ZrO 2 crystals as well as SrAl 2 Si 2 O 8 gel have been studied using X‐ray diffraction (XRD), scanning electron microsc…
Lead magnesium niobate titanate (PMN-PT) thin films were prepared on Pt-coated magnesium oxide single-crystal substrate (Pt(100)/MgO(100)) and Pt- and Ti-coated oxidized Si wafer (Pt(111)/Ti/SiO 2 /Si(100)) at 680-780° C by metalorganic chemical vapor deposition (MOCVD). The PMN-PT thin films comprising perovskite str…
The radial distribution function of a new form of amorphous diamond, synthesized from ${\mathrm{C}}_{60}$ fullerene by shock compression and rapid quenching, was obtained from an electron diffraction pattern using an imaging plate. The present amorphous diamond was essentially amorphous material based on diffractometr…
Grain growth of ZnO during liquid‐phase sintering of a ZnO‐6 wt% Bi 2 O 3 ceramic was investigated for A1 2 O 3 additions from 0.10 to 0.80 wt%. Sintering in air for 0.5 to 4 h at 900° to 1400°C was studied. The AI 2 O 3 reacted with the ZnO to form ZnAl 2 O 4 spinel, which reduced the rate of ZnO grain growth. The Zn…

Highly [100]-oriented Pb(Zr, Ti)O 3 (PZT) films were prepared on (100) GaAs and (100) Si substrates with MgO buffer layer by pulsed laser ablation (PLA). The depth profile of the constituent elements observed by X-ray photoelectron spectroscopy (XPS) shows that there are no remarkable interdiffusion and/or no formatio…
Capacitance aging under dc field has been studied on BaTiO 3 -based dielectrics with X7R characteristics for multilayer ceramic capacitors with Ni internal electrodes. Capacitance change strongly depends on additives and firing conditions as well as microstructure. Aging behavior under no dc field is well explained by…

This paper describes the growth and properties of micro-machined semiconductor microbolometers. These thermally isolated structures are employed in uncooled infrared detectors developed at the Defence Science and Technology Organisation (DSTO). Recent research is focused towards developing high performance bolometers…

We demonstrate that completely dense yttria‐stabilized zirconia (YSZ) electrolyte films <5 μm thick can be reactively sputter deposited onto porous (∼0.5 μ pore size) La 0.8 Sr 0.2 MnO 3 substrate/electrodes. The two key factors in achieving the fully dense films were porous substrate preparation and the use of substr…
