title: The Stellar Equilibrium Constant: connecting Radiation, Gravity, and Thermodynamics

description: We discover a universal stellar equilibrium constant, I = 4πGσ/c⁴, that governs all thermal photospheres. This invariant emerges from the intersection of radiative equilibrium, Newtonian gravity, and relativistic compactness, yielding the identity I = (Φβ²)/(T⁴R²) = 4πGσ/c⁴, where Φ = L/(Mg) and β = GM/(Rc²). 

 

The constant depends only on fundamental constants (G, σ, c), reducing stellar observables (L, M, R, T) from four to three independent parameters. Classical relations—Eddington luminosity, Kelvin-Helmholtz timescale, radiation pressure—emerge as algebraic projections of this single identity rather than independent laws.

 

Numerical verification across the Sun, Sirius A, Vega, and WR 124 confirms I_left/I_right = 1.000±10⁻¹⁶. Empirically, the photogravitational parameter Φ clusters by Wolf-Rayet spectroscopic subtype (±10%), enabling direct mass determination from (L, R) alone with ~1-2% accuracy. Applied to 46 WR stars, this reveals a systematic ~43% mass deficit relative to evolutionary tracks—evidence of missing physics in massive star models.

The invariant establishes photospheres as critical geometric-thermodynamic boundaries where nature's constants enforce a universal constraint, providing falsifiable diagnostics (ΔI, ΔSB) for detecting non-thermal departures in any self-luminous system.

title: <b>Mineral-catalyzed geopolymerization threatens iron-associated organic carbon persistence in anoxic environments</b>

description: The sequestration of organic carbon (OC) through mineral association in soils and sediments is a crucial process that regulates carbon sink dynamics and the global carbon cycle. However, minerals can participate in both abiotic and biotic OC transformations, altering the persistence of mineral-associated OC under anoxic conditions. In this work, we report that synergistic interactions among metal (oxyhydr)oxides, such as iron (Fe), manganese (Mn), and aluminum (Al) drive the polymerization of simple organic molecules into macromolecular geopolymers, increasing their electron transfer capacity by 52–115%. These geopolymers function as electron shuttles, enhancing OC decomposition through microbial dissimilatory iron reduction. This reduces the mean retention time (MRT) of OC bound to active and inert Fe minerals by 51.4 ± 15.6% and 74.1 ± 13.7%, respectively. Future carbon turnover models should explicitly account for the mineral composition, redox fluctuations, and microbial metabolic pathways to advance the understanding of the Earth’s carbon sink.

title: Extraterrestrial Regolith Simulant Database

description: This project is a dataset of extraterrestrial regolith simulants, organized in a table to facilitate sorting and filtering. The original source database was created by Kevin Cannon at Colorado School of Mines as the "Planetary Simulant Database" as a free resource, but later went defunct. In 2024 the American Society of Civil Engineers (ASCE) Aerospace Division (ASD) Advanced Materials and Structures (AMS) Committee started efforts to re-create the database in a tabular format and add to it based on new developments.

Each row of the database represents a different simulant. Columns are grouped as follows:
- Basic Information
- Mineralogy
- Bulk Chemistry
- Physical Properties

It is anticipated that the ASCE-ASD-AMS Committee will continue to maintain this database moving forward such that a persistent DOI is maintained along with a revision history as new simulants are added.

title: Main code for difference image with L2 regularization. from Full-field mechanics imaging by direct inversion of electrical data

description: Self-sensing materials with deformation-dependent electrical conductivity have been studied in diverse applications. A limitation of self-sensing materials is that they do not directly report on the underlying condition of the material. That is, it would be much more useful to know the actual stresses, strains or damages that give rise to observed conductivity changes. The process of deducing material condition from electrical data is called the <i>self-sensing inverse problem</i> (SSIP). Previous work has required electrical impedance tomography (EIT) as an intermediate step to estimate the conductivity distribution prior to estimating the spatially varying mechanics. But this is undesirable because EIT is an ill-posed inverse problem and is highly dependent on regularization, which renders the SSIP as subject to the same assumptions and limitations of EIT. The contribution of this manuscript is the development of a <i>direct</i> SSIP formulation that omits the EIT step such that mechanics are predicted directly from voltage–current data. The effects of regularization type, regularization norm and formulation (difference versus absolute imaging) are also explored. The direct SSIP formulation is experimentally validated on a soft carbon nanofibre-modified polyurethane pressure sensor and compared to ANSYS-solved mechanics with good agreement.
