Understanding the creep property of heat-resistant Al alloy by analyzing eutectic phase/matrix interface structures

Materials Research Letters, 2023
Interface characteristics are of great importance in mechanical performance for multi-phases heat-resistant Al alloys. Herein, Al3Sc precipitates were created at both Al/Al9FeNi interface and Al matrix inside Al–Fe-Ni eutectic alloy by microalloyed Sc ...

Constructive Matrix Theory [PDF]

, 2007
We extend the technique of constructive expansions to compute the connected functions of matrix models in a uniform way as the size of the matrix increases. This provides the main missing ingredient for a non-perturbative construction of the $\phi^{\star

Generalized Matrix Mechanics [PDF]

, 2002
We propose a generalization of Heisenbergs' matrix mechanics based on many-index objects. It is shown that there exists a solution describing a harmonic oscillator and many-index objects lead to a generalization of spin algebra.Comment: Latex, 16pages ...

Low-temperature sequential deposition for efficient inverted perovskite solar cells

Nature Communications
Inverted perovskite solar cell has made significant progress in recent years. Although two-step sequential deposition shows the benefits to obtain higher quality large-size perovskite crystals, the high annealing temperature, which is required to achieve

Site-selected thionated benzothioxanthene chromophores as heavy-atom-free small-molecule photosensitizers for photodynamic therapy

Communications Chemistry, 2022
Site-selective thionation is a powerful strategy to access heavyatom-free small-molecule photosensitizers for photodynamic therapy. Here, a series of sulfur-substituted benzothioxanthene chromophores is synthesized and the sequential insertion of sulfur ...

Matrix thermalization [PDF]

Journal of High Energy Physics, 2017
Matrix quantum mechanics offers an attractive environment for discussing gravitational holography, in which both sides of the holographic duality are well-defined. Similarly to higher-dimensional implementations of holography, collapsing shell solutions in the gravitational bulk correspond in this setting to thermalization processes in the dual quantum

Neurotrophin signaling is a central mechanism of salivary dysfunction after irradiation that disrupts myoepithelial cells

npj Regenerative Medicine, 2023
The mechanisms that prevent regeneration of irradiated (IR) salivary glands remain elusive. Bulk RNAseq of IR versus non-IR human salivary glands showed that neurotrophin signaling is highly disrupted post-radiation.

High Sulfur Resistance Gunless Through-Tubing Perforation Technology

Cejing jishu
To improve the perforation efficiency of through-tubing in integrated production strings for acidic gas fields and reduce complex failures, a high sulfur-resistant gunless through-tubing perforation technology is developed. A downhole system for plugging
