An Organic Semiconductor Lasing Crystal Featuring Triplet‐Triplet Annihilation

Aggregate
Organic semiconductor lasers are attractive for low thresholds and cost, but triplet accumulation hampers their electrically pumped development. Compared to existing organic lasing materials, triplet‐triplet annihilation (TTA) systems are capable of ...

Tailored Hierarchical Porous Copper Architectures via Three Dimensional Printing and Pressure‐less Sintering for Next‐Generation Lithium‐Metal Batteries

Advanced Engineering Materials, EarlyView.
A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Investigation of simultaneous 2R regeneration of two 40 Gb/s channels in a single optical fiber [PDF]

, 2008
We experimentally investigate the simultaneous all-optical signal processing of two 40-Gb/s wavelength-division multiplexing optical streams spaced by ~5 nm using self-phase modulation and offset filtering in a single highly nonlinear fiber to achieve a ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...
