The plastid genome (plastome) is a rich source of phylogenetic and other comparative data in plants. Most land plants possess a plastome of similar structure. However, in a major group of plants, the ferns, a unique plastome structure has evolved. Th

We examined populations of perennial, shrubby buckwheats in the Eriogonum corymbosum complex and related Eriogonum spe- cies in the subgenus Eucycla , to assess genetic affiliations of the recently named E. corymbosum var. nilesii . The known populat

Thermally stimulated luminescence from X-irradiated Gd2SiO5:Ce, measured in the interval 300–700 K, is characterized by a main glow peak near 390 K and weaker maxima near 420, 490 and 550 K. Analysis of the well-resolved principal peak shows that i

Single crystals of the high temperature ceramic boron carbide have been synthesized by the optical floating zone method. Room temperature elastic constants of a carbon-deficient boron carbide single crystal have been measured using the resonant ultra

Thermally stimulated luminescence measurements on cerium-doped M 2 SiO 5 (M=Lu, Y, Yb, Er) and undoped Lu 2 SiO 5 , each possessing monoclinic C2/c crystal symmetry, reveal common glow peaks with the principal one occurring near 375 K. In contrast, c

Temperature-dependent optical absorption of cerium-doped gadolinium oxyorthosilicate (Gd2SiO5:Ce) has been measured and analyzed for impurity-ion-lattice coupling parameters and oscillator strengths. Although the spectrum consists of overlapping Ce3+

Optical absorption of single-crystal, cerium-doped lutetium oxyorthosilicate has been carefully measured in the temperature interval 10-300 K. Prominent Gaussian absorption peaks occur at 3.432{+-}0.002 eV (peak a), 3.502{+-}0.002 eV (peak b), 4.236{

Highly conductive biaxially textured (both normal to and in the film plane) RuO2 and La0.5Sr0.5CoO3 thin films have been deposited on SiO2/Si substrates for the first time. Yttria-stabilized zirconia (YSZ) produced by ion-beamassisted-deposition (IBA

We have grown biaxially textured La0.5Sr0.5CoO3 (LSCO) thin films on technically important SiO2/Si substrates by pulsed laser deposition, where a biaxially oriented yttria-stabilized zirconia (YSZ) produced by ion-beam-assisted deposition (IBAD) is u

A coating system for the deposition of in-plane oriented yttria-stabilized zirconia (YSZ) template films on 1 cm wide flexible metal substrates is presented. In static mode, the system is capable of producing high quality template films on 20 cm subs
