A green solvent processable, self‐doped N‐annulated perylene butyl tetraester applied as a solar cell cathode interlayer

Polymer International, EarlyView.
A new organic molecular cathode interlayer is presented built upon the perylene butyl tetraester scaffold. The new molecule incorporates N‐annulation and a functional amine group to control optical, electrochemical and physical properties and delivers excellent solar cell performance. Abstract We report a new amino‐bay‐substituted, N‐annulated perylene

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling

Small, EarlyView.
Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...

Silver‐Modulated Copper Dynamics Under Pulsed Tandem Electrochemical CO2 Reduction

Small, EarlyView.
Under pulsed CO2 reduction, Ag does more than provide CO for tandem catalysis. It redirects how Cu dissolves, redeposits, and remains catalytically relevant, generating an Ag‐rich yet Cu‐active working state. Correlative surface and solution analysis reveal that tandem performance emerges from dynamic material redistribution rather than from a static ...

Beyond Integer Charge Transfer: A New Design Rule Linking Dopant Strength and Counterion Separation to Efficient Carrier Transport in Conjugated Polymers

Small, EarlyView.
In this Research Article, the authors introduce a new design principle for doped conjugated polymers, showing that dopant energy depth relative to the host polymer (ΔE) can be leveraged to minimize Coulomb interactions and boost conductivity. This discovery offers a new and simple strategy to optimize the performance of organic electronics for everyday

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Effect of Different Surface Treatments on Resistance to Abrasive Wear of AISI 4140 Steel

steel research international, EarlyView.
This study investigates how different surface treatments affect resistance to abrasive wear of AISI 4140 Steel. The wear rate was significantly higher in samples subjected to conventional treatments than in samples coated using the HVOF process, demonstrating the superior efficiency of coatings applied by thermal spraying in mitigating abrasive wear ...

Exploring Use‐Wear Texture Quantification Through Confocal Microscopy on Tools Made From Volcanic Rocks (Basalt and Phonolite)

Archaeometry, EarlyView.
ABSTRACT Functional analysis is essential for reconstructing lithic tool use. Recent approaches combining confocal microscopy and surface texture analysis provide quantitative alternatives to traditional visual use‐wear analysis, although their application to coarse‐grained, heterogeneous rocks remains challenging because of their complex surface ...
