Recent Advances in Light‐Addressable Electrochemistry for Spatially Resolved Applications

Advanced Materials Technologies, EarlyView.
This comprehensive review highlights light‐addressable electrochemistry as a powerful tool that uses light to control localized chemical reactions on unstructured semiconductor surfaces. The work evaluates advanced strategies to optimize electrode materials for enhanced spatial resolution and stability. Furthermore, it showcases diverse applications in

Super-Eddington Magnetized Neutron Star Accretion Flows: A Self-similar Analysis

The Astrophysical Journal
The properties of super-Eddington accretion disks exhibit substantial distinctions from the sub-Eddington ones. In this paper, we investigate the accretion process of a magnetized neutron star (NS) surrounded by a super-Eddington disk.

Evolution of Pre-Main Sequence Accretion Disks

, 2003
The aim of this project is to develop a comprehensive global picture of the physical conditions in, and evolutionary timescales of, pre-main sequence accretion disks.

Maximal possible accretion rates for slim disks [PDF]

, 2008
By adopting the correct vertical gravitational force in studies of thermal equilibrium solutions, we find that there exists a maximal possible accretion rate for each radius in the outer region of optically thick accretion flows, such that only the inner

Synergistic Interfacial Regulation by Nano‐TiO2 and Carboxylated Cellulose Nanofibers for Multiscale Surface Stabilization of Cementitious Composites

Advanced Materials Technologies, EarlyView.
Nano‐TiO2 and carboxylated cellulose nanofibers jointly regulate hydration‐product distribution in cementitious composites. Improved microstructural continuity and refined pore structure accompany enhanced strength and surface stability without a substantial increase in overall hydration.

Circumstellar Disk Accretion Across the Lagoon Nebula: The Influence of Environment and Stellar Mass

The Astronomical Journal
Pre-main-sequence disk accretion is pivotal for determining the final stellar properties and the early conditions for close-in planets. We aim to establish the impact of internal (stellar mass) and external (radiation field) parameters on the disk ...

Tidal disruption of a low-mass star in an active galactic nucleus as the origin of the PS16dtm outburst

Astronomy & Astrophysics
Context. The event PS16dtm, which occurred in the centre of the narrow-line Seyfert 1 (NLS1) galaxy SDSS J015804.75−005221.8 (z = 0.080440), is one of the few candidates for a tidal disruption event in an already-accreting active galactic nucleus.

Accretion disks around black holes [PDF]

, 1994
The physics of accretion flow very close to a black hole is dominated by several general relativistic effects. It cannot be described by the standard Shakura Sunyaev model or by its relativistic version developed by Novikov and Thome.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.
