Diffusion of Dopants and Components in Arsenic-Implanted CdTe/HgCdTe Structures under Different High-Temperature Annealing Conditions

open access: yesProceedings, 2019
The CdTe cap layers were grown on CdZnTe-substrated HgCdTe (MCT) LPE epilayers by magnetron sputtering and thermal evaporation. The diffusion behaviors of Cd & Hg components and impurities (As or In) in these CdTe/MCT structures subjected to As ion ...

Spontaneous formation of bright solitons in self-localized impurities in Bose-Einstein condensate

open access: yes, 2015
We study the formation of bright solitons in the impurity component of Bose-Einstein condensate (BEC)-impurity mixture by using the time-dependent Hartree-Fock-Bogoliubov theory.

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Motion of an impurity particle in an ultracold quasi-one-dimensional gas of hard-core bosons

open access: yes, 2008
The low-lying eigenstates of a one-dimensional (1D) system of many impenetrable point bosons and one moving impurity particle with repulsive zero-range impurity-boson interaction are found for all values of the impurity-boson mass ratio and coupling ...

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

open access: yesAdvanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Impurity, Moral Substantiality, and Social Control: A Gender Perspective

open access: yesReligions
The notion of impurity is identified in numerous belief systems, ranging from certain religions to nationalisms. Understanding its nature and functioning beyond its concrete objects is therefore a fundamental anthropological question.

Cooperative interplay between impurities and charge density wave in the phase transition of atomic wires

open access: yesNew Journal of Physics, 2015
Impurities interact with a charge density wave (CDW) and affect the phase transitions in low-dimensional systems. By using scanning tunneling microscopy, we visualize the interaction between oxygen impurities and the CDW in indium atomic wires on Si(111),

Current patterns and magnetic impurities in time-reversal breaking superconductor

open access: yes, 1999
We study the impurity effect in the time reversal symmetry (${\cal T}$) breaking superconductor based on the Bogoliubov-de Gennes (BdG) equations. In ${\cal T}$-violating superconductors, spontaneous currents are induced around the impurity.

Influence of Sample Preparation and Processing Procedures on the Thermal Diffusivity of MgO‐C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.
