Self‐Doped Perylene Diimide‐Based Polymers for Simultaneous Improvements in Efficiency and Thermal Stability of Organic Solar Cells

open access: yesSmall, EarlyView.
PPV‐M, an amorphous electron transporting polymer with a high Tg of 118°C, suppresses thermally induced molecular diffusion in organic solar cells. Unlike crystalline PDINN (Tg = 61°C) with a T80 of only 8 h, PPV‐M maintains efficient electron extraction and extends T80 to 637 h, representing an 80‐fold enhancement in thermal stability.

HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

open access: yessteel research international, EarlyView.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...
