Advanced Materials Interfaces, EarlyView.Novel p‐type graphene/InAs quantum dot (QD)/n‐type GaAs mixed‐dimensional heterojunction structures are demonstrated for 1.3 µm light‐emitting diodes The p‐graphene serves as an ultrathin hole injection layer and the hybrid device shows 800 × stronger electroluminescence output powers than the reference LEDs without p‐graphene.

Phenomenological Material Model for First-Order Electrocaloric Material
Energies, 2023 Caloric cooling systems are potentially more efficient than systems based on vapour compression. Electrocaloric cooling systems use a phase transformation from the paraelectric to the ferroelectric state by applying or removing an electric field to pump ...

Ultrafast Anisotropic Optical‐Gap Shift in Low‐Symmetry Layered GeS
Advanced Optical Materials, EarlyView.This study reveals ultrafast, anisotropic optical‐gap shift dynamics in GeS. Optical excitation induces a significant redshift in the polarization along the zigzag direction, about three times greater than that along the perpendicular armchair direction.

Dynamic Friction Model for the Investigation of Stick‐Slip Oscillations
Chemical Engineering &Technology, Volume 46, Issue 1, Page 29-36, January 2023., 2023 An efficient dynamic friction model based on the Stribeck curve is presented, which allows to investigate the influencing parameters on the stick‐slip effect through finite element simulations. The simulation of a tribometer test proofs that the model correlates well with the tribometer test results.

A Theoretical Investigation on Coupled Mass‐charge Transport in a Binary Fluid
Advanced Theory and Simulations, EarlyView.This study presents a theoretical framework for coupled mass‐charge transport in binary fluids using molecular dynamics simulations. By deriving governing equations from conservation laws and Onsager's theory, the approach introduces generalized diffusivity and electrostatic friction terms.

Chemical Engineering &Technology, Volume 46, Issue 1, Page 95-101, January 2023., 2023 The bulk shear and wall slip of a confined nonpolar lubricant, a complex branched‐hydrocarbon oil, were studied using molecular dynamics simulation. Different temperatures and molecular masses were investigated for a Couette flow. As the number of branches of the liquid molecule increases, the shear stresses and the wall slip increase.
