Generalized Chemical Model for Warm Dense Hydrogen: Ionization Potential Depression and Molecular Dissociation Shifts

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Warm dense matter (WDM) is a complex state, where quantum effects, thermal excitations, and strong interparticle correlations coexist. Understanding its microscopic composition and medium‐induced modifications of atomic and molecular properties is essential for planetary modeling, fusion research, and high‐energy‐density experiments.

Age Analysis of Extrasolar Planets: Insight from Stellar Isochrone Models

open access: yesThe Astronomical Journal
There is growing evidence from stellar kinematics and galactic chemical evolution suggesting that giant planets ( M _P ≥ 0.3 M _J ) are relatively young compared to the most commonly occurring population of small planets ( M _P < 0.3 M _J ).

A Review of Black Phosphorus‐Based Materials: From Preparation Strategies to Characterization Techniques

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The structure, properties, preparation methods, and characterization techniques of BP. As a typical 2D layered material, black phosphorus (BP) demonstrates exceptional promise in various fields, particularly in energy storage for alkali metal‐ion batteries. However, its distinctive structure and properties, together with the compositional complexity of

White dwarf planets

open access: yesEPJ Web of Conferences, 2013
The recognition that planets may survive the late stages of stellar evolution, and the prospects for finding them around White Dwarfs, are growing. We discuss two aspects governing planetary survival through stellar evolution to the White Dwarf stage ...

Modeling the Probability of Tsunami Fire Ignition Based on Data From the 2011 Tohoku and 2024 Noto Peninsula Earthquakes, With Recommendations to Reduce Emerging Fire Risk in Tsunami Vertical Evacuation Structures

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Recent tsunamigenic earthquakes in Japan have highlighted the emerging fire hazard triggered by tsunami inundation and its impact on tsunami vertical evacuation (TVE) structures. This new type of fire following earthquake, referred to as “tsunami fires,” may be a potential universal hazard that tsunami‐prone countries face; however, it has not

Amino‐functionalized lanthanide metal‐organic frameworks encapsulating boron‐doped graphene quantum dots: A paper based fluorescent sensor to visual detection of salicylic acid

open access: yesFlexMat, EarlyView.
Abstract Salicylic acid (SA), a widely distributed environmental pollutant, requires accurate detection for effective water quality monitoring and ecological protection. In this work, we developed a highly sensitive fluorescent sensor by encapsulating boron‐doped graphene quantum dots (B‐GQDs) within amino‐functionalized lanthanum‐based metal‐organic ...
