Twenty‐Minute Microwave‐Enabled Dual‐Anion Nickel Sulfoselenide Anodes for High‐Capacity Sodium/Potassium‐Ion Batteries and Durable Pouch Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
A dual‐anion‐assisted strategy is proposed for designing bi‐functional high‐performance anodes. The preparation of NiSSe/N‐C within 20 min demonstrates rapid Na+/K+ reaction kinetics, exceptional rate capability, and remarkable cycling stability. Nickel‐based materials are promising anode candidates for sodium‐ion batteries and potassium‐ion batteries ...

Intersection Numbers of the Natural Embedding of the Twisted Triality Hexagon T ( q 3 , q ) in PG ( 7 , q 3 )

open access: yesJournal of Combinatorial Designs, Volume 34, Issue 7, Page 306-329, July 2026.
ABSTRACT In this paper, we study and characterise the natural embedding of the twisted triality hexagon T ( q 3 , q ) in PG ( 7 , q 3 ). We begin by describing the possible intersections of subspaces of PG ( 7 , q 3 ) with T ( q 3 , q ). Then, we provide conditions on a set of lines ℒ, which ensure that ℒ forms the line set of a naturally embedded ...

Multiaxial Fatigue Behavior of AA6016 and AA6016 to DX54D SPR Joints: Fracture Mechanisms and Data‐Driven Rupp's Model

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2929-2944, July 2026.
ABSTRACT The fatigue and fracture behavior of self‐piercing rivet (SPR) joints between AA6016 aluminum sheets (1–2 mm) and DX54D steel (0.95 mm) was studied under 90°, 45°, and 0° multiaxial loading. Pure shear (90°) loading produced the highest fatigue strength, whereas multiaxial (45°) loading resulted in reduced performance, with pure tension (0 ...

Covers of PG(3,q) and of finite generalized quadrangles

open access: yes, 1998
This article studies covers in PG(3, q) and in generalized quadrangles. The excess of a cover is defined to be the difference between the number of lines in the cover and the number of lines in a spread.

Thermal and Photocatalytic Conversion of CO2 to Ethanol: Advances in Catalyst Design, Challenges, and Opportunities

open access: yesChemSusChem, Volume 19, Issue 12, 26 June 2026.
This review examines thermo‐ and photocatalytic routes for converting CO2 to ethanol and analyzes how metal alloying, promoters, supports, surface structure, and semiconductor design govern catalyst activity, selectivity, and stability. It integrates mechanistic insights from experimental and theoretical studies and identifies the main challenges and ...
