Pulsed laser deposition for growth of high quality epitaxial garnet films for low threshold waveguide lasers

open access: yes, 2007
Pulsed laser deposition (PLD) is a mature technique capable of producing extremely high quality epitaxial single crystalline films. We have grown Nd:doped garnet films of GGG (Gd The talk will summarise our progress using conventional (single beam) PLD ...

Effect of Atomic Layer Deposition of Ultra‐Thin Oxide on Reactivity and Durability of Perovskite Oxygen Electrodes

open access: yesAdvanced Materials, EarlyView.
This table of contents illustrates that the mechanism for mitigating Sr segregation depends strongly on the chemistry of the coating layer. HfO2 electrostatically stabilizes the surface by lowering the surface oxygen vacancies, which serve as the driving force for Sr migration. On the other hand, Al2O3 and Fe2O3 react with segregated Sr to form Sr‐Al‐O

Surface Reordering During Layer‐by‐Layer Growth on SrTiO3

open access: yesAdvanced Materials, EarlyView.
Surface structures (left) derived from DFT‐constrained fitting to crystal truncation rods measured by synchrotron X‐ray scattering (right) after each monolayer of deposition during the MBE growth of SrTiO3${\rm SrTiO}_{3}$ (001). The bottom panel shows the bare substrate, the middle panel shows island formation upon deposition of a single layer of SrO,

Transparent Perovskite Light‐Emitting Diodes with Conductive Oxide Top Electrodes

open access: yesAdvanced Materials, EarlyView.
Transparent perovskite light‐emitting diodes (TrPeLEDs) enable simultaneous display and transparency, expanding application possibilities. Using a metal oxide buffer layer and pulsed laser deposition, TrPeLEDs with diverse compositions and architectures are demonstrated.

Identification and Characterization of Phospholipase D Genes Putatively Involved in Internal Browning of Pineapple during Postharvest Storage

open access: yesFrontiers in Plant Science, 2017
Phospholipase D (PLD) in plants plays vital roles in growth, development, and stress responses. However, the precise role of PLDs in pineapple remains poorly understood.

Optical Manipulation of Multiferroic Phases in BiFeO3 Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
At the strain‐driven morphotropic phase boundary, optical control over the multiferroic rhombohedral and tetragonal phase mixture is demonstrated using above‐bandgap light illumination. The photoinduced charge carriers modify the electrostatic environment and induce the conversion into a single tetragonal phase.

Modulation Identification and Carrier Recovery System for Adaptive Modulation in Satellite Communications [PDF]

open access: yes, 2005
We introduce the modulation identification technique implementing the multimode phase locked loop (PLL) in the satellite communication using adaptive modulation scheme which is a countermeasure against the rain attenuation.

High‐Throughput Screening of REBCO Superconducting Thin Films Fabricated Via Combinatorial Inkjet Printing and TLAG Process

open access: yesAdvanced Materials Technologies, EarlyView.
A methodological framework is presented for combinatorial REBCO thin films fabricated by drop‐on‐demand inkjet printing with controlled Rare Earth composition gradients. Automated, synchrotron‐based, and local characterization techniques produce comprehensive property maps that correlate composition and TLAG process parameters with superconducting ...

Activation of phospholipase D-2 by P2X7 agonists in rat submandibular gland acini

open access: yesJournal of Lipid Research, 2002
Exogenous ATP stimulated phospholipase D (PLD), but not sphingomyelinase in rat submandibular gland (SMG) acini. PLD activation was dependent upon extracellular Ca2+ and did not involve intracellular Ca2+ mobilization or phosphoinositide-specific ...

Local Real-Space View of the Achiral 1$T$-TiSe$_2$ 2 $\times$ 2 $\times$ 2 Charge Density Wave

open access: yes, 2018
The transition metal dichalcogenide 1$T$-TiSe$_2$ is a quasi-two-dimensional layered material undergoing a commensurate 2 $\times$ 2 $\times$ 2 charge density wave (CDW) transition with a weak periodic lattice distortion (PLD) below $\approx$ 200 K ...
