Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

open access: yesAdvanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Synthesis of Large‐ and Medium‐Sized Heterobiaryl Atropisomeric Rings and Atropopeptides by Catalytic Intramolecular SNAr

open access: yesAngewandte Chemie, EarlyView.
Catalytic, intramolecular N‐heterocycle arylation by nucleophilic aromatic substitution (SNAr) is now available for synthesis of highly strained macrocycles and medium‐sized heterobiaryl atropisomeric rings, including atropopeptides. Key to the approach is the ability to generate a strong base catalytically, taking advantage of base‐embedding ...

Laser‐Induced Rashba Spin‐Orbit Torques in Multiferroic Semiconductor (Ge,Mn)Te

open access: yesAdvanced Science, EarlyView.
Femtosecond optical excitation generates two distinct effective spin–orbit torques in the multiferroic semiconductor (Ge,Mn)Te. Photoinduced holes drive coherent magnetization precession through a subpicosecond shift of the easy axis, while changes in ferroelectric sublattice displacements modify magnetic ordering via the Rashba interaction.

Fluids under High Pressure Insighted by Operando Neutron Imaging and Molecular Dynamics Simulations

open access: yesAdvanced Physics Research, EarlyView.
There is limited research on how fluids behave under the extreme conditions found in fuel gas systems (high pressure) and catalytic reactors (high temperature and pressure). Neutron Imaging provides experimental data on interfacial tension, and Henry's law volatility constant, apparent molar volume, and diffusion coefficient for systems from toluene ...

Unlocking Circular Economy Potentials: Testing the Moderating and Mediating Roles of Cultural Diversity, Technological Innovation, and Digitalization

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Green finance (GF) has emerged as a key policy instrument for advancing the circular economy (CE), yet its impact varies considerably across OECD countries. Existing research has not sufficiently examined how institutional, technological, and cultural contexts shape this relationship.
