Tunnelling Processes-Driven Radiative Recombination in Complex Oxide Scintillators

, 2010
Photo- and thermo-luminescence techniques are applied to several kinds of single crystal complex oxide scintillators to reveal tunnelling-driven radiative recombination processes.

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

Advanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Isotope effect on the formation of CN by radiative association reactions

AIP Advances
The formation of CN and its isotopologue C15N through radiative association has been investigated. We considered two processes for the collisions of ground state C(3P) and N(4S) atoms (A2Π → X2Σ+ and b4Π → a4Σ+), as well as, for the first time, we ...

Kinetic model of radiative recombination processes in 2H-MoS2 crystals

Moldavian Journal of the Physical Sciences, 2006
Steady-state photoluminescence (PL) measurements revealed 2H-MoS2 crystals. Two distinct radiative regions in the near infrared are performed. The first region consisting of several sharp lines is produced by bound excitons related to the halogen ...

Numerical Method for Chemical Non-Equilibrium Plume Radiation Characteristics of Solid Rocket Motors

Aerospace
The research objectives of engine plume radiation calculation primarily encompass two aspects: (1) addressing the additional heating induced by plume radiation on rocket thermal protection systems and (2) elucidating the variation patterns of spectral ...

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring

Advanced Engineering Materials, EarlyView.
Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

How two-dimensional are planet–disc interactions?

Astronomy & Astrophysics
Context. The ring and gap structures found in observed protoplanetary disks are often attributed to embedded gap-opening planets and typically modeled with simplified thermodynamics and in the 2D, thin disk approximation.

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).
