Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

Advanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Withdrawal capacity of screws in plywood and manufacturer dependencies

Engineering Structures
Within civil engineering and design of load-bearing timber structures, the use of self-tapping screws for connections is common practice. In certain situations, the axial withdrawal capacity of screws in a wooden panel may be required, for instance when utilizing the rope-effect contribution to the lateral resistance.

Reduced wound healing capacity in alcohol abusers – reversibility after withdrawal

Clinical Health Promotion - Research and Best Practice for patients, staff and community, 2012
BackgroundAlcohol abusers have increased risk of wound complications following surgical procedures, however the development of complications is reduced after preoperative withdrawal from alcohol. Therefore the aim of the study was to evaluate wound healing at alcohol abuse and after withdrawal.

Enhancing Optoelectronic Properties in Phthalocyanine‐Based SURMOFs: Synthesis of ABAB Linkers by Avoiding Statistical Condensation with Tailored Building Blocks

Advanced Functional Materials, EarlyView.
A novel phthalocyanine (PC)‐based metal–organic framework (MOFs) is synthesized using ditopic PC linkers obtained through regioselective statistical condensation. The resulting MOF exhibits significant improvements in electronic absorption, thereby enhancing the material's performance in light harvesting and energy conversion.

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

Advanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.
