A heterometallic σ-silane adduct from cooperative reactivity of an iron-aluminium complex. [PDF]

open access: yesChem Commun (Camb)
Protonation of a heterometallic silanide complex with an alcohol led to formation of a σ-silane complex. This reaction does not require a strong acid or a weakly coordinating anion.

Photochemical H2 Activation by an Zn–Fe Heterometallic: A Mechanistic Investigation [PDF]

open access: yes, 2023
Addition of H2 to a Zn–Fe heterometallic complex was observed to occur under photochemical conditions (390 or 428 nm LED) and leads to the formation of the corresponding metal dihydride.

Cryptographic Puzzles and Complex Systems

open access: yes, 2021
A puzzle lies behind password authentication (PA) and blockchain proof of work (PoW). A cryptographic hash function is commonly used to implement them. The potential problem with secure hash functions is their complexity and rigidity.

Do evolutionary algorithm dynamics create complex network structures? [PDF]

open access: yes, 2021
This paper presents a novel method for visualizing the dynamics of evolutionary algorithms in the form of complex networks. We discuss the analogy between individuals in populations in an arbitrary evolutionary algorithm and vertices of a complex network,

Anisotropic Electrical Conductivity of a Single-Crystalline Oxo-Bridged (Cr4Mo2VI)-Mo-III Heterometallic Complex

open access: yes, 2021
A new oxo-bridged chromium-molybdenum heterometallic complex, O-CrMoHC ([Cr-4(MoO4)(2)O-2(OAc)(4)(DMF)(4)]center dot 2DMF), was synthesized by using a simple solvothermal reaction.
