Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

The Greek monetary system and its derivations over other ancient Mediterranean systems.

open access: yesDocumenta & Instrumenta, 2016
One of the main features of the Greek currency are the big differences between emissions of the polis, which did not match either in their iconographic message types, not even in the met-rical pattern of their values.

Functions to map photoelectron distributions in a variety of setups in angle-resolved photoemission spectroscopy

open access: yes, 2018
The distribution of photoelectrons acquired in angle-resolved photoemission spectroscopy can be mapped onto energy-momentum space of the Bloch electrons in the crystal.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Erken Dönem Hadis Münekkitlerinden Ebû İshak el-Cûzecânî’nin Nâsıbîlikle İtham Edilmesinin Tenkidi

open access: yesTrabzon İlahiyat Dergisi, 2021
Hz. Peygamber’in vefatından sonra görülen siyasî ve mezhebî olaylar İslam tarihinde muhtelif düşünce ve fırkaların oluşumuna neden olmuştur. Bidʻat görüşlerin yayılması hadis ilminde isnadın sorulmasına ve böylece cerh ve taʻdîl ilminin gelişimine sebep ...

Search for Cosmic-Ray Antideuterons

open access: yes, 2005
We performed a search for cosmic-ray antideuterons using data collected during four BESS balloon flights from 1997 to 2000. No candidate was found. We derived, for the first time, an upper limit of 1.9E-4 (m^2 s sr GeV/nucleon)^(-1) for the differential ...

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

open access: yesAdvanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...
