Improving the thin-disk models of circumstellar disk evolution. The 2+1-dimensional model

open access: yes, 2017
Circumstellar disks of gas and dust are naturally formed from contracting pre-stellar molecular cores during the star formation process. To study various dynamical and chemical processes that take place in circumstellar disks prior to their dissipation ...

Self‐Powered Real‐Time Temperature Sensing Based on Flexible Ionic Elastomer on Triboelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a self‐powered real‐time ionic TENG temperature sensing system for flexible thermal management with high and real‐time temperature monitoring. Ionic liquids and elastomer chains are investigated under temperature via electrochemical and physical analysis, resulting in enhancing thermal sensitivity and output performance on TENG ...

A Two-zone Accretion Disk in the Changing-look Active Galactic Nucleus 1ES 1927+654: Physical Implications for Tidal Disruption Events and Super-Eddington Accretion

open access: yesThe Astrophysical Journal
The properties of slim accretion disks, while crucial for our understanding of black hole growth, have yet to be studied extensively observationally. We analyze the multiepoch broadband spectral energy distribution of the changing-look active galactic ...

Asymptotic analysis of the axisymmetric problem for the transverse compression of a thin elastic disk in the case of mixed boundary conditions along its faces [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
The axisymmetric problem for the transverse compression of a thin elastic disk is considered in slip absence.  An asymptotic solution for the interior stress-strain state is constructed.

Anionic Citrate‐Based 3D‐Printed Scaffolds for Tunable and Sustained Orthobiologic Delivery to Enhance Tissue Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A potent anionic citric acid‐based 3D‐printed scaffold is developed for the sustained and controlled release of orthobiologics to enhance orthopedic therapeutic efficacy. Comprehensive in vivo studies demonstrated effective bone fusion and high safety at a low dose of BMP‐2 delivered by the system, establishing it as a promising platform for safe ...

Imprint of Accretion Disk-Induced Migration on Gravitational Waves from Extreme Mass Ratio Inspirals

open access: yes, 2011
We study the effects of a thin gaseous accretion disk on the inspiral of a stellar--mass black hole into a supermassive black hole. We construct a phenomenological angular momentum transport equation that reproduces known disk effects.

Formation of 2D Electron Gas at a Non‐Polar Perovskite Oxide Interface: SrHfO3/BaSnO3

open access: yesAdvanced Functional Materials, EarlyView.
Through experiments and Poisson‐Schrödinger simulations, 2D electron gas formed at the non‐polar SrHfO3/BaSnO3 interface is observed. A large conduction band offset enables modulation doping by the intrinsic deep donors in SrHfO3, resulting in carrier confinement in BaSnO3 without relying on interfacial polarization or termination‐layer engineering ...
