The Kramers escape rate of phase transitions for the 6-dimensional Gauss-Bonnet AdS black hole with triple phases

open access: yesPhysics Letters B
In this study, we obtain specific picture of the phase transitions for the 6-dimensional Gauss-Bonnet Anti-de Sitter (AdS) black hole with triple phases, using the generalized free energy we constructed and Kramers escape rate in stochastic motion. There

Thermodynamics of a Non-Stationary Black Hole Based on Generalized Uncertainty Principle

open access: yesJournal of Physics: Theories and Applications, 2017
In the general theory of relativity (GTR), black holes are defined as objects with very strong gravitational fields even light can not escape. Therefore, according to GTR black hole can be viewed as a non-thermodynamic object.

Chemically Fueled Systems Chemistry Across Length Scales

open access: yesAdvanced Functional Materials, EarlyView.
Chemically fueled reaction cycles regulate processes through single and multiple catalytic sites on the molecular and assembly scale. This gives rise to unique kinetically controlled properties/functions like spatio‐temporal catalysis, oscillations, optical properties, and perform work.

Assessing the Role of Intrinsic Variability in Black Hole Parameter Inference Using Multiepoch EHT Data

open access: yesThe Astrophysical Journal Letters
Event Horizon Telescope (EHT) observations of M87* provide a means of constraining the parameters of both the black hole and its surrounding plasma.

Polarization‐Dependent Synaptic‐Like Electro‐Optical Response in Ferroelectric Nematic Liquid Crystals

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric nematic liquid crystals (FNLCs) offer fast, tunable polarization and low‐voltage operation but suffer from poor polarization retention at zero field. Semiconductor‐modified FNLCs enhance polarization retention and exhibit short‐ and long‐term electro‐optical responses, while also supporting spike‐type signal integrations.

Halide Perovskite Integrated Photovoltaic Cathodes Incorporating Pt on ZIF‐8‐Derived Carbon for Solar Hydrogen Production

open access: yesAdvanced Functional Materials, EarlyView.
A low‐Pt catalyst supported on zeolitic imidazolate framework (ZIF‐8)‐derived porous carbon and graphite is integrated with a halide perovskite photovoltaic, yielding cathodes that achieve a high photocurrent density (∼20 mA cm−2) under simulated sunlight and exhibit remarkable stability in acidic media over several days, thereby demonstrating a ...
