Surface boiling – an “obvious” explanation for the observed limiting temperature of finite nuclei

EPJ Web of Conferences, 2012
Limits of stability of nuclear systems are explored within the framework of a finite-range interacting Fermi gas model and microcanonical thermodynamics in Thomas-Fermi approximation.

Making Photoresponsive Metal–Organic Frameworks an Effective Class of Heterogeneous Photocatalyst

Advanced Functional Materials, EarlyView.
This review summarizes photoresponsive MOFs for photocatalytic applications, focusing on their capacity to enhance light harvesting, charge transfer, and surface reactions. While existing studies provide foundational insights, emerging characterization techniques enable a deeper understanding of photoresponsive MOFs.

Nonlinearly charged dyonic black holes

Nuclear Physics B, 2020
In this paper, we investigate the thermodynamics of dyonic black holes in the presence of Born-Infeld electromagnetic field. We show that electric-magnetic duality reported for dyonic solutions with Maxwell field is omitted in case of Born-Infeld ...

Second Law of Thermodynamics, Macroscopic Observables within Boltzmann's Principle but without Thermodynamic Limit [PDF]

arXiv, 2001
Boltzmann's principle S=k ln W allows to extend equilibrium thermo-statistics to ``Small'' systems without invoking the thermodynamic limit. The clue is to base statistical probability on ensemble averaging and not on time averaging. It is argued that due to the incomplete information obtained by macroscopic measurements thermodynamics handles ...

Tin‐Based 2D/3D Perovskite Vertical Heterojunction for High‐Performance Synaptic Phototransistors

Advanced Functional Materials, EarlyView.
Phototransistors based on tin‐based 2D/3D perovskite heterostructures show an ultrahigh responsivity and detectivity at a low gate voltage across a broad wavelength region from ultraviolet to near‐infrared. The devices can replicate neuromorphic learning and remembering behaviors to light stimuli, in addition to electric depression and memory erasure ...

Classification of complex systems by their sample-space scaling exponents

New Journal of Physics, 2018
The nature of statistics, statistical mechanics and consequently the thermodynamics of stochastic systems is largely determined by how the number of states W ( N ) depends on the size N of the system. Here we propose a scaling expansion of the phasespace

Over 18% Efficiency from Halogen‐Free Solvent‐Processed Polymer Solar Cells Enabled by Asymmetric Small Molecule Acceptors with Fluoro‐Thienyl Extended Terminal

Advanced Functional Materials, EarlyView.
An asymmetric non‐fullerene acceptor BTP‐FT is developed by extending the end group of Y6‐BO with thiophene. The conformation of the molecule is determined by the noncovalent F···S interaction as demonstrated by 2D NMR and simulations. An efficiency of 18.39% is achieved in the resulting ternary solar cells processed from toluene.

Coupling computational thermodynamics with density-function-theory based calculations to design L12 precipitates in FeNi based alloys

Materials & Design, 2020
Achieving a high-volume fraction of thermodynamically stable L12-type precipitates that are resistant to coarsening is of great importance for the development of low-cost FeNi based austenitic steels.

Regioselective and Anisotropic Multi‐Patching of Small Microparticles via a Polymer Brush‐Assisted Microcontact Printing (µCP)

Advanced Functional Materials, EarlyView.
A method to fabricate anisotropic SiO2 patchy microspheres is presented using a modified microcontact printing technique. This involves a PDMS elastomer stamp with grooved surface topography, creating a confined environment for the microspheres.

Exploring Electronic States and Ultrafast Electron Dynamics in AlInP Window Layers: The Role of Surface Reconstruction

Advanced Functional Materials, EarlyView.
This study examines the surface characteristics of AlInP (001), crucial for advanced solar cells and photoelectrochemical devices. Using theoretical modeling and experiments, it identifies how phosphorus‐rich and indium‐rich surfaces create mid‐gap states that pin the Fermi level and influence ultrafast electron dynamics.
