A topological characterization of an almost Boolean algebra

open access: yesExtracta Mathematicae
For any Boolean space X and a discrete almost distributive lattice D, it is proved that the set C(X, D) of all continuous mappings of X into D, when D is equipped with the discrete topology, is an almost Boolean algebra under pointwise operations ...

Discocelia Plataet Sp. n., a Small Incertae Sedis Cercozoan Flagellate

open access: yesJournal of Eukaryotic Microbiology, Volume 72, Issue 5, September/October 2025.
ABSTRACT Cercozoa = Filosa (Rhizaria, SAR) is one of the largest rhizarian subgroups and consists of a diverse assemblage of amoeboid and flagellated protists. They are ecologically significant in microbial food webs, widely diverse, and even abundant in soils and deep marine sediments according to environmental sequencing.

Enhancement of Dynamical Coupling in Artificial Spin‐Ice Systems by Incorporating Perpendicularly Magnetized Ferromagnetic Matrix

open access: yesSmall Structures, Volume 6, Issue 7, July 2025.
A new type of artificial spin ice (ASI) lattices, i.e., in the ASI system embedded in the perpendicular magnetic anisotropy (PMA) matrix, is proposed. The numerical simulations reveal a strong magnon–magnon coupling between the bulk second‐order mode of the ASI and the fundamental mode of the PMA matrix, supported by a pronounced anticrossing frequency

Molecular precursor pathway to Co1−xNixNb2O6 for photocatalytic dye degradation: Optical and charge transport studies

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 7, July 2025.
The (micro)structure, morphology, optical, photocatalytic, electrical and dielectric properties of mixed metal oxides CoNb2O6, NiNb2O6 and Co0.5Ni0.5Nb2O6, prepared through a modified single‐source molecular precursor route, were investigated. Abstract A new approach for the formation of binary and ternary mixed metal oxides, namely, CoNb2O6, NiNb2O6 ...

Towards Sustainable Sulfide‐Based All‐Solid‐State‐Batteries: An Experimental Investigation of the Challenges and Opportunities Using Solid Electrolyte Free Silicon Anodes

open access: yesBatteries &Supercaps, Volume 8, Issue 2, February 2025.
This work includes a comparative evaluation between solid electrolyte blended and solid electrolyte free silicon‐anodes for all–solid–state batteries. Furthermore, we explored the innovative approach of utilizing non‐toxic and environmentally friendly solvents by employing a polyacrylic acid (PAA) binder, which was dissolved in either water or ethanol.

Characterization of Allobodo yubaba sp. nov. and Novijibodo darinka gen. et sp. nov., cultivable free‐living species of the phylogenetically enigmatic kinetoplastid taxon Allobodonidae

open access: yesJournal of Eukaryotic Microbiology, Volume 72, Issue 1, January/February 2025.
Abstract Kinetoplastids are a large and diverse protist group, spanning ecologically important free‐living forms to medically important parasites. The taxon Allobodonidae holds an unresolved position within kinetoplastids, and the sole described species, Allobodo chlorophagus, is uncultivated, being a necrotroph/parasite of macroalgae. Here we describe

Surface‐Engineered Pt‐Ni(111) Nanocatalysts for Boosting Their ORR Performance via Thermal Treatment

open access: yesChemElectroChem, Volume 11, Issue 22, November 18, 2024.
Pt−Ni nano‐octahedra annealed in different gas atmospheres exhibit distinct ORR activity profiles. The catalyst treated with hydrogen (H2/Ar) annealing showed reduced surface Ni species and resulted in superior mass and specific activities for ORR. After 20,000 potential cycles, the catalyst maintained a mass activity of 3.92 A/mgPt, surpassing the ...

Results in lattices, ortholattices, and graphs [PDF]

open access: yes, 2011
This dissertation contains two parts: lattice theory and graph theory. In the lattice theory part, we have two main subjects. First, the class of all distributive lattices is one of the most familiar classes of lattices. We introduce π-versions of five
