Alpha-balanced graphs and matrices and GF(3)-representability of matroids

open access: yesJournal of Combinatorial Theory, Series B, 1982
AbstractA graph with {±1} labels on the edges is α-balanced if the sum of the labels on each induced cycle is congruent (mod 4) to the related entry of a given vector α. A {0, ±1} matrix is α-balanced if an associated graph with {±1} labels on the edges is α-balanced.

A Dual‐Functional Electrolyte Additive for Highly Reversible Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces tetrabutylammonium bromide (TBAB) as a dual‐function additive for aqueous zinc‐ion batteries. TBAB disrupts the hydrogen‐bond network of water while TBA+ adsorbs on Zn to improve interfacial wettability and regulate Zn2+ flux, resulting in suppressed dendrite growth and parasitic reactions. This synergy extended the lifespan of Zn|

Interlayer Expansion of Bulk MoS2 via Top‐Down Organic Pillaring Enables Tunable Li+ Intercalation and Controlled Solvent Co‐Intercalation

open access: yesAdvanced Functional Materials, EarlyView.
Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake

Symmetry codes over GF(3) and new five-designs

open access: yesJournal of Combinatorial Theory, Series A, 1972
AbstractFor every odd prime power q where q ≡ −1(3) we define a (2q + 2, q + 1) code over the field of three elements. It is shown that all the codes in this family are self orthogonal.For q = 5, the (12, 6) code is equivalent to the extended Golay code. For q = 11, it can be shown that the minimum weight of the (24, 12) code is 9.

Long‐Term Hydrophilic, Anti‐Clotting, and Anti‐Fibrotic Dynamic Covalent Silicone‐Based Biomaterials

open access: yesAdvanced Healthcare Materials, EarlyView.
Dynamic covalent crosslinking of a Schiff‐base silicone elastomer with hydrazide‐functionalized polymers is demonstrated to improve the long‐term hydrophilicity as well as the anti‐fouling and anti‐clotting properties of PDMS implants. The hydrazone‐functionalized material prevents hydrophobic recovery, resists clotting, and significantly reduces ...

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.
