KTA is a crystallographic isomorph of KTP that shows promise for nonlinear frequency generation throughout the 1–5-μm region. We present updated Sellmeier coefficients for KTA based on measurements of the refractive index in the 0.4–3.6-μm region. Predictions of phase-matching behavior by means of these coefficients a…
Diatoms were extracted from subsampled sections of four dated sediment cores collected in the mesohaline Chesapeake Bay, U.S.A. Over 400 species in 76 genera were identified. A complete list of the species identified from the cores is given, together with information on their relative abundance. Forty-six of the more…

Muconate cycloisomerase (EC 5.5.1.1) and chloromuconate cycloisomerase (EC 5.5.1.7) were purified from extracts of Rhodococcus erythropolis 1CP cells grown with benzoate or 4-chlorophenol, respectively. Both enzymes discriminated between the two possible directions of 2-chloro-cis, cis-muconate cycloisomerization and…
Thermoluminescence dosimetry is extensively used for quantitative dose measurements in various irradiation fields such as dosimetry of brachytherapy sources. In this application, small doses on the order of 0.5 cGy must be accurately measured, which requires careful control of instrumentation, energy-dependence, and n…
We show that a nonequilibrium cation distribution is the likely explanation for the 47-K rise in the Curie temperature of ultrafine ${\mathrm{MnFe}}_{2}$${\mathrm{O}}_{4}$ particles found by Kulkarni et al. This nonequilibrium cation distribution is argued to be caused, in part, by oxidation of ${\mathrm{Mn}}^{2+}$ to…

Ultrasonic velocity in glasses denoted by the composition formula x 2 Li 2 O·(1- x 2 ) B 2 O 3 ( x 2 is the mole fraction) is measured over the composition range 0≤ x 2 ≤0.28 at 10 MHz and 298 K by the ultrasonic pulse-echo overlap method. The elastic property of the glasses is analyzed in terms of the three structura…
Abstract Extensive Monte Carlo simulations are presented for the Fried‐Binder model of block copolymer melts, where polymer chains are represented as self and mutually avoiding walks on a simple cubic lattice, and monomer units of different kind (A, B) repel each other if they are nearest neighbors (ε AB > 0). Choo…
We report on the effect of high pressure on the room-temperature emission spectra and lifetimes of ${\mathrm{Cr}}^{3+}$:GSGG (${\mathrm{Gd}}_{3}$${\mathrm{Sc}}_{2}$${\mathrm{Ga}}_{3}$${\mathrm{O}}_{12}$) and ${\mathrm{Cr}}^{3+}$:GGG (${\mathrm{Gd}}_{3}$${\mathrm{Ga}}_{5}$${\mathrm{O}}_{12}$). In both systems we observ…
Grain growth of ZnO in liquid‐phase‐sintered ZnO‐Bi 2 O 3 ceramics containing systematic additions of TiO 2 to the 0.55 wt% level has been studied for flring in air from 900° to 1400°C. The Bi 2 O 3 melts during flring, and then the TiO 2 dissolves into the Bi 2 O 3 ‐rich liquid. The TiO 2 initially reacts with the Bi…
We report the use of rigorous coupled-wave diffraction analysis in conjunction with the simulated annealing optimization method for performing optimal design of binary-level surface-relief diffractive elements with subwavelength, submicrometer features that exhibit quasi-linear-phase transmittance. An element designed…

Iron poly- and oligocrystals with a carbon mass content of 0.02 % were cold rolled to a technical strain () of 90 % and annealed at 1000 K in a salt bath furnace for 1 to 300 s. The polycrystals had an initial grain size of about 20 μm. The oligocrystals consisted of 20–40 grains with a longitudinal extension of 10–20…
Many advantages of ferroelectric compositions in the lead zirconate:lead titanate (PZT) solid solutions for both sensing and actuation are explored. The state of understanding of both intrinsic single domain and extrinsic domain wall and phase boundary contribution to response is described, and the composition manipul…
Polyhydroxybutyrate (PHB) is an optically active polymer of D(−)3-hydroxybutyric acid. It is a naturally occurring polymer produced by a wide variety of bacteria. It serves as an intracellular storage material for carbon and energy and is accumulated as granules within the cytoplasm [1–4] of the bacteria. The chemical…
The interaction of atomic oxygen with a Ru(001) surface was studied using x-ray photoelectron spectroscopy, thermal desorption, and electron diffraction. The onset of the reaction of dissolved oxygen with the Ru host starts only for equivalent oxygen coverages higher than 50 monolayers (ML). A new Ru 3d core level shi…
The SrTiO3(110) surface, after annealing in ultrahigh vacuum (UHV) was observed by scanning tunneling microscopy/spectroscopy (STM/S). These observations were compared with the ultraviolet photoemission spectroscopy (UPS) and x-ray photoemission spectroscopy (XPS) data previously reported. The surface, after annealing…
