Poly(iminoborane)s with Aromatic Side Groups: Insights into the Microstructure from Monodisperse Model Oligomers

ChemistryEurope
While certain inorganic main‐group polymers such as silicones (polysiloxanes) are ubiquitous in our everyday life, poly(iminoborane)s have been elusive for a long time.

A Thermodynamic 3D Model for the Simulation of Diffusion‐Controlled Alloying Processes in Heterogeneous Material Structures

Advanced Engineering Materials, EarlyView.
A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

Nickel(0)‐Catalyzed [2+2+2] Cycloadditions of Linked Bisdiynes with Diaryl Alkynes Generates D‐π‐A‐π‐D Bis(arylethynyl)indane‐Based Organic Frameworks as Noncytotoxic Probes for Ds‐DNA/Ds‐RNA

ChemistryEurope
Nickel(0)‐catalyzed [2 + 2 + 2] cycloadditions of linked bisdiynes with diarylacetylenes were performed using the Ni(II) precursor complex [(TMEDA)Ni(o‐tolyl)Cl] in the presence of PPh3 ligands to generate the active Ni(0) species. Optimal reactivity was

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

Advanced Engineering Materials, EarlyView.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Investigation of Oxygen‐Free Wetting Behavior of Aluminum on Copper via Molecular Dynamics Simulations and Experiments

Advanced Engineering Materials, EarlyView.
The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

Decarboxylation of β-boryl NHPI esters enables radical 1,2-boron shift for the assembly of versatile organoborons

Nature Communications, 2023
In recent years, numerous 1,2-R shift (R = aliphatic or aryl) based on tetracoordinate boron species have been well investigated. In the contrary, the corresponding radical migrations, especially 1,2-boryl radical shift for the construction of ...
