π-Extended Ladder-Type Conjugated Polymers via BN-Annulation

open access: yesOrganic Materials, 2021
Two kinds of ladder-type conjugated polymers were concisely synthesized by the formation of single-stranded conjugated polymers via Stille cross-couplings, followed by nitrogen-directed electrophilic borylations at electron-rich aromatic rings.

Toward Hydrogen‐Free and Dendrite‐Free Aqueous Zinc Batteries: Formation of Zincophilic Protective Layer on Zn Anodes

open access: yesAdvanced Science, 2022
Rechargeable aqueous Zn‐ion batteries (ZIBs) are regarded as one of the most promising devices for the next‐generation energy storage system. However, the uncontrolled dendrite growth on Zn metal anodes and the side hydrogen evolution reaction, which has

The (Greatest) Fragment of Classical Logic that Respects the Variable-Sharing Principle (in the FMLA-FMLA Framework)

open access: yesBulletin of the Section of Logic, 2021
We examine the set of formula-to-formula valid inferences of Classical Logic, where the premise and the conclusion share at least a propositional variable in common. We review the fact, already proved in the literature, that such a system is identical to

Aniline dimers serving as stable and efficient transfer units for intermolecular charge-carrier transmission

open access: yesiScience, 2023
Summary: Because any perturbation in the number of oxidation sites associated with the polymeric backbone can cause changes in the electrical properties, the stability of electrical properties has strongly prevented the wide adoption of most conducting ...

M-matrix and inverse M-matrix extensions

open access: yesSpecial Matrices, 2020
A class of matrices that simultaneously generalizes the M-matrices and the inverse M-matrices is brought forward and its properties are reviewed. It is interesting to see how this class bridges the properties of the matrices it generalizes and provides a

The almost semimonotone matrices

open access: yesSpecial Matrices, 2019
A (strictly) semimonotone matrix A ∈ ℝn×n is such that for every nonzero vector x ∈ ℝn with nonnegative entries, there is an index k such that xk > 0 and (Ax)k is nonnegative (positive).

Investigation of the friction weldability of an AlSi10MnMg-alloy reinforced with 30 Vol.-% silicon carbide particles with the adequate monolithic material

open access: yesJournal of Advanced Joining Processes, 2022
Due to their positive properties, AMC materials represent a current trend in industrial applications and thus a major research focus. But currently their difficult machinability limits a full establishment.
