The Role of Cold Atmospheric Plasma in Surface Modification and Adhesion Behavior of Polypropylene/Flax Biocomposites

open access: yesPolymer Composites, EarlyView.
Effects of plasma surface treatment on adhesive bonding of PP/flax biocomposites. ABSTRACT The emphasis on environmental sustainability has accelerated the adoption of biocomposites as alternatives to synthetic composites. However, their low surface energy may limit adhesion in bonding applications.

Process Window Optimization for Roll‐to‐Roll Slot‐Die Coating of High‐Resolution Dry Film Solder Resists for HDI PCB Applications

open access: yesPolymer Engineering &Science, EarlyView.
A hydrodynamic process window for roll‐to‐roll slot‐die coating of photosensitive solder resist (PSR) was established by systematically varying the slot‐die gap and pump flow rate. Under the optimized conditions, a highly uniform 26 μm dry‐film solder resist (DFSR) layer with a thickness variation of ±3.74% was obtained without coating defects.

Control System for the Navigation of the Agricultural Robots: A Review

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

Revealing the Impact of Phase Transition on n = 1 2D Perovskite Photodetectors With Intrinsically Tunable Narrowband Detection

open access: yesSmall, EarlyView.
Spectrally tunable narrowband photoconductors have been achieved based on n = 1 2D perovskite (PEA)2PbBrxI4‐x. Achieved the highest D* of 1011 Jones at 20 V. This research revealed the two different stacking orders in pure compositions and studied phase segregation in mixed halides, which quenched device performance.

Data informed performance assessment and structural health monitoring for existing and historical concrete structures

open access: yesStructural Concrete, EarlyView.
Abstract Our generation inherits this cultural heritage of historic material and historic reinforced concrete structures and thus bears a certain responsibility to preserve these historic buildings with the help of the new technologies of lifetime management, conservation concepts and the new digitalization as well as the emerging safety concepts of ...

Impact of half‐joint failures on RC girder bridges: A robustness quantification study

open access: yesStructural Concrete, EarlyView.
Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...
