Structural Aspects of Lithium‐Ion Conduction in the Phosphidotitanate Li8TiP4 and Its Comparison With Li7+5xTa1−xP4 and Li8−xTi1−xTaxP4

open access: yesChemistry – A European Journal, Volume 32, Issue 13, 1 April 2026.
ABSTRACT The chemical system Li/Ti/P has previously been subject to intensive investigation. However, reliable structural data for the reported phases have remained elusive. Motivated by the growing interest in phosphorus‐based lithium‐ion conductors, we have reinvestigated the synthesis, crystal structure, and physical properties of Li8TiP4.

Arithmetic geometry of toric varieties. Metrics, measures and heights

open access: yes, 2014
We show that the height of a toric variety with respect to a toric metrized line bundle can be expressed as the integral over a polytope of a certain adelic family of concave functions.

Red Blood Cell Membrane Mechanics Using Discrete Exterior Calculus (DEC) and Optimization

open access: yesInternational Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 4, April 2026.
We present a novel DEC approach for calculating RBC shapes applicable to other cell types and membrane problems. We derive an energy minimization equation that can be solved semi‐implicitly, and a Lie derivative method to control node spacing. This novel work should aid computational modeling in many biological situations.

Record‐Low Compressibility in [N(C2H5)3CH3]FeCl4 Expands Phase Engineering Horizons in Hybrid Molecular Ferroelectrics

open access: yesSmall, Volume 22, Issue 23, 22 April 2026.
High‐pressure studies of the lead‐free hybrid organic–inorganic ferroelectric [N(C2H5)3CH3]FeCl4 demonstrate record low compressibility, establishing it as the least compressible molecular ferroelectric known. In situ diamond anvil cell experiments identify halide selection and inorganic sublattice tuning as key compressibility controls, advancing ...

Atomic‐Scale Capture the Kinetics of Oxygen Precipitates in Crystalline Silicon

open access: yesSmall Structures, Volume 7, Issue 4, April 2026.
Our study present a comprehensive, atomic‐scale investigation of oxygen precipitates kinetics in crystalline silicon. The morphological evolution of OPs during their growth is fundamentally a facet‐determined behaviors.The OP ablation process uncovers a novel dual‐synergistic mechanism driven by oxygen back‐diffusion, involving both edge epitaxy and ...

Street‐to‐Pipe Diagnosis of Compound Rain–Tailwater Flooding in a Coastal Combined Sewer System: Sewer Pre‐Filling and Outfall Throttling

open access: yesEarth's Future, Volume 14, Issue 4, April 2026.
Abstract Compound flooding in coastal cities occurs when heavy rainfall coincides with tide‐driven tailwater that reduces combined sewer system (CSS) discharge capacity, yet this coupling is rarely quantified from street to pipe scale. We develop a high‐resolution 1‐D/2‐D drainage–inundation model for Hoboken, New Jersey, calibrating the 1‐D drainage ...

Archaeometric Characterization of Submerged Sasanian Stucco From Ghaleh Guri, Western Iran

open access: yesArchaeometry, Volume 68, Issue S1, Page S84-S93, April 2026.
ABSTRACT The Ghaleh Guri archaeological site, a late Sasanian site with a building complex dated to 591–628 ce, lies along an ancient road linking the western Zagros to Mesopotamia. Its architectural remains, adorned with stucco, faced annual river floods yet remained stable for centuries.

A Miyaoka–Yau inequality for hyperplane arrangements in CPn$\mathbb {CP}^n$

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 4, April 2026.
Abstract Let H$\mathcal {H}$ be a hyperplane arrangement in CPn$\mathbb {CP}^n$. We define a quadratic form Q$Q$ on RH$\mathbb {R}^{\mathcal {H}}$ that is entirely determined by the intersection poset of H$\mathcal {H}$. Using the Bogomolov–Gieseker inequality for parabolic bundles, we show that if a∈RH$\mathbf {a}\in \mathbb {R}^{\mathcal {H}}$ is ...

Fast and Slow Signal Propagation in Abiotic Polypeptide Assemblies

open access: yesChemBioChem, Volume 27, Issue 6, 27 March 2026.
Proteinoid microspheres formed by thermal polymerization of amino acids exhibit spontaneous electrical potential fluctuations without genetic material, membranes, or ion channels. Multi‐electrode recordings and electron microscopy reveal composition‐dependent voltage oscillations, long‐term drifts, and correlated signals across electrodes.
