Flexible white thermally activated delayed fluorescence polymer with alkyl spacer and side‐chain encapsulation for efficient solution‐processed white organic light‐emitting diodes

FlexMat, EarlyView.
A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).

Fretting Wear and Fatigue Life Analysis of Fuel Bundles Subjected to Turbulent Axial Flow in CEFR

Science and Technology of Nuclear Installations, 2019
In a fast spectrum reactor, the fuel rod bundle is mainly positioned radially by the wire which can make contact with the adjacent fuel rods, and then it is inevitable that flow-induced vibration (FIV) will cause fretting wear and vibration fatigue of ...

Knee arthroplasty failure is associated with significant systemic multimetal exposure

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study investigated whether patients scheduled for revision total knee arthroplasty (TKA) are systemically exposed to arthroplasty metals, and whether systemic metal levels in these patients differ depending on the implants' levels of constraint.

The Influences of Wear Debris on the Fretting Wear Behavior of Inconel718 Laser Cladding Alloy Layer [PDF]

Cailiao Baohu
Fretting wear is a material damage phenomenon caused by small vibrations between tightly contacting surfaces.Studying the role of debris in fretting wear is of great significance for revealing the damage evolution of materials during fretting wear.In ...

An energy description of wear mechanisms and its applications to oscillating sliding contacts [PDF]

, 2003
To quantify wear rates, the Archard approach is classically applied. It relates the wear volume to the product of the sliding distance and the normal load.

‘I, Me, Myself’: Selfhood and Melancholy in the Journals of Gertrude Savile (1697–1758)

Journal for Eighteenth-Century Studies, EarlyView.
Abstract This article examines the journals of Gertrude Savile from 1727 in light of recent scholarship on early modern and eighteenth‐century melancholy. The concept had myriad associations with medicine, physiology, the imagination, and feeling, but questions remain about how melancholy during this period was considered by those outside the narrow ...

Multiaxial Fatigue Behavior of AA6016 and AA6016 to DX54D SPR Joints: Fracture Mechanisms and Data‐Driven Rupp's Model

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The fatigue and fracture behavior of self‐piercing rivet (SPR) joints between AA6016 aluminum sheets (1–2 mm) and DX54D steel (0.95 mm) was studied under 90°, 45°, and 0° multiaxial loading. Pure shear (90°) loading produced the highest fatigue strength, whereas multiaxial (45°) loading resulted in reduced performance, with pure tension (0 ...
