Interaction of Dirac δ$$ \delta $$‐Waves in the Inviscid Levine and Sleeman Chemotaxis Model

Mathematical Methods in the Applied Sciences, Volume 49, Issue 7, Page 6492-6506, 15 May 2026.
ABSTRACT This article investigates interactions of δ$$ \delta $$‐shock waves in the inviscid Levine and Sleeman chemotaxis model ut−λ(uv)x=0$$ {u}_t-\lambda {(uv)}_x=0 $$, vt−ux=0$$ {v}_t-{u}_x=0 $$. The analysis employs a distributional product and a solution concept that extends the classical solution concept.

Shannon and Rényi Entropies of Molecular Densities Under Atomic Partitioning: Insights Into Extensity and an Incomplete Description of Electron Correlation

International Journal of Quantum Chemistry, Volume 126, Issue 10, May 15, 2026.
At infinite separation, a diatomic molecule reduces to two noninteracting subsystems. The electron density decomposes into atomic densities, while the Rényi entropy functional reveals both additive atomic contributions and nonadditive terms. None of these terms contains any trace of the presence of static correlation effects, particularly important in ...

Electrochemical Oxidation of Abietic and Dehydroabietic Acids for Sustainable Access to C‐7 and C‐15 Oxygenated Abietanes

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
Batch and flow electrochemical methods enable direct C‐7 oxidation of abietic and dehydroabietic acids from colophony or their methyl derivatives to the corresponding ketones, while a mediated protocol enables additional C‐15 oxygenation, providing sustainable and selective routes to diversified abietane derivatives.

Using Lignin and Spent Coffee Grounds as Bio‐Additives in 3D‐Printable Poly Lactic Acid/Multi‐Walled Carbon Nanotube Composites for Advanced Electronic Applications

Polymer Composites, Volume 47, Issue 9, Page 8261-8272, 10 May 2026.
Bio‐based additives derived from lignin and spent coffee grounds (SCG) are used to enhance MWCNT dispersion in PLA composites, enabling improved electrical conductivity and reliable in material extruded strain‐gauge sensors. ABSTRACT In this work, three bio‐based additives, lignin, spent coffee grounds (SCG), and oil extracted from SCG (Ox‐SCG) were ...

Electro‐Chemo‐Mechanical Coupling in Hf0.5Zr0.5O2 Ferroionic Heterostructures

Advanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
Schematic of a ferroionic HZO heterostructure where epitaxial interfaces enable dynamic oxygen‐vacancy exchange, coupling ionic and ferroelectric degrees of freedom. Vacancy‐mediated polarization modulation biases HZO polymorphism, suppresses leakage, and enhances piezoelectric response, yielding distinct butterfly‐loop evolution and diode‐like ...
