Bimetallic Nanoparticles as Cocatalysts for Photocatalytic Hydrogen Production

Advanced Functional Materials, EarlyView.
Recent developments have introduced bimetallic nanoparticles as effective cocatalysts for photocatalytic systems. This review explores the rapidly expanding research on bimetallic cocatalysts for photocatalytic production of hydrogen, emphasizing the creation of carrier‐selective contacts, localized surface plasmon resonance effects, methodologies for ...

Scalarization of Taub-NUT black holes in extended scalar-tensor-Gauss-Bonnet theory

Journal of High Energy Physics
Recently, the scalarization of the Schwarzschild black hole has been extensively studied. In this work, we explore the scalarization of the Taub-NUT black hole within the context of the extended scalar-tensor-Gauss-Bonnet theory, which admits a Ricci ...

Non-extensive entropic corrected thermal stability and geometries of well-known black holes

Nuclear Physics B
In this study, we investigate the thermodynamic stability and geometries of well-known black holes such as the spherical static black hole, charged Einstein-Gauss-Bonnet black hole and R-N black hole of the dyadosphere in the presence of Barrow and Gauss-

Accretion, Primordial Black Holes and Standard Cosmology

, 2011
Primordial Black Holes evaporate due to Hawking radiation. We find that the evaporation time of primordial black holes increase when accretion of radiation is included.Thus depending on accretion efficiency more and more number of primordial black holes ...

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

How a Klein–Nishina Modified Eddington-limited Accretion Explains Rapid Black Hole Growth in the Early Universe

The Astrophysical Journal
The discovery of quasars and their supermassive black holes (SMBHs) over 10 ^9 ${M}_{{\rm{\odot }}}$ merely hundreds of millions of years after the Big Bang generates tension with the idea of Eddington-limited accretion and pressures the community into ...

Joule–Thomson expansion of Kerr–AdS black holes

European Physical Journal C: Particles and Fields, 2018
In this paper, we study Joule–Thomson expansion for Kerr–AdS black holes in the extended phase space. A Joule–Thomson expansion formula of Kerr–AdS black holes is derived.
