Wide‐Field Bond Quality Evaluation Using Frequency Domain Thermoreflectance with Deep Neural Network Feature Reconstruction

open access: yesAdvanced Materials Interfaces, EarlyView.
In this work, wide‐field (>1 mm2) frequency‐domain thermoreflectance (FDTR) hyperspectral imaging is used to image subsurface indium bump bonds 50 µm below the surface. Thermal analysis with Monte Carlo uncertainty propagation is used to evaluate bump quality, while a trained deep neural network (can rapidly reconstruct bump geometry contact area maps.

Enhancing Plasma Electrolytic Oxidation (PEO) Coatings on Magnesium Alloys: The Critical Role of Surface Pretreatments

open access: yesAdvanced Materials Interfaces, EarlyView.
This review explores how various surface pretreatment methods—such as heat treatment, severe plastic deformation, laser modification, immersion, and cold spray—enhance the performance of PEO coatings on magnesium alloys. The study highlights how these pretreatments influence coating microstructure, adhesion, and corrosion resistance, offering new ...

Water Nanofilms Mediate Adhesion and Heat Transfer at Hematite‐Hydrocarbon Interfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Work of adhesion, Wsl, shown as a function of water coverage for the weak, intermediate and strong solid–liquid interaction strengths. Anhydrous and hydroxylated surfaces are represented by unfilled and filled markers, respectively. The result for the anhydrous surface with the strong solid liquid interactions (Wsl = 405 mJ m−2) is not shown ...

V-V compact group of galaxies [PDF]

open access: yes
A search for X-ray emission from five compact groups of galaxies with the Einstein Observatory revealed detections from three groups. Soft, extended X-ray emission was observed in Stephan's Quintet which is most likely caused by hot intracluster gas ...

Structural Evolution During Repeated Spray Deposition of FeCl₃‐Doped Poly(Styrene)‐b‐Poly(4‐Vinyl Pyridine) Layers

open access: yesAdvanced Materials Interfaces, EarlyView.
The structure formation mechanism of pure poly(styrene)‐b‐poly(4‐vinyl pyridine) (PS‐b‐P4VP) and hybrid PS‐b‐P4VP/FeCl₃ films during and after spray deposition is investigated. The morphological differences result from the interplay among the complexation between FeCl₃ and P4VP segments, the crystallization of the P4VP segment, and the surface ...

Rationalizing the Unexpected Inefficiencies of 3D Porphyrin‐MOFs as Singlet Oxygen Photosensitizers Against Botrytis cinerea

open access: yesAdvanced Materials Interfaces, EarlyView.
Unexpected results show that the singlet‐oxygen based antifungal activity of porphyrin‐based Metal‐Organic Frameworks is far below expectations while the standalone ligand is more efficient. We attribute these behaviours to inefficient exciton migration and gas diffusion leading to low singlet oxgyen concentrations at and beyond the MOF‐gas interface ...

Generality, Specificity And Discovery [PDF]

open access: yes
This paper offers a meta-theory concerning the relation between the general and the specific in science. This issue was recently called back to attention by Hodgson (2001). A heuristic of discovery, developed in earlier work (Nooteboom 1992, 1996, 1999b,
