Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces

Advanced Functional Materials, EarlyView.
Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.

3D‐Printed Hygroscopic Polymer Networks for High‐Humidity Triboelectric Nanogenerators to Wirelessly Power Implantable Electronic Devices‐ A Conceptual Pathway

Advanced Functional Materials, EarlyView.
This work develops 3D‐printable tribopolymer networks that can enhance triboelectric performance under high humidity environments. Polar hydrophilic functional groups and incorporation of zwitterionic monomers promote bound‐water–dominated interfacial polarization thereby increasing electrical outputs.

Tracing Sub‐Monolayer Contamination on Wafer‐Scale 2D Materials

Advanced Functional Materials, EarlyView.
Sub‐monolayer adventitious carbon contamination limits the performance and reproducibility of 2D material‐based devices. This study demonstrates scanning helium microscopy (SHeM) as a non‐destructive, ultra‐sensitive tool for wafer‐scale imaging of surface cleanliness.

The process of web wrinkle formation on a roller and its prevention with a curved axis roller (A web transfer simulation for roller tilt)

Nihon Kikai Gakkai ronbunshu
The process of a trough stepping into a wrinkle during web transfer is simulated by FEM commercial software. Two models are employed. The first one consists of a web and four cylindrical rollers, while the second one has a curved axis roller instead of a

Wrinkle ridges in the floor material of Kasei Valles, Mars: Nature and origin [PDF]

Wrinkle ridges on Mars occur almost exclusively in smooth plains material referred to as ridged plains. One of the largest contiguous units of ridged plains occurs on Lunae Planum on the eastern flank of the Tharsis rise.

Analysis of hybrid woven fabrics with shape memory alloys wires embedded [PDF]

, 2010
Until recently, Shape Memory Alloys (SMAs) were predominantly developed for applications in the biomedical and engineering industry, and only a limited number of applications in textiles are known. Fabrics made of natural fibres (e. g.

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

Advanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Engineering Intelligent Graphene Oxide‐Cellulose Membranes: Suppressing Thermal Runaway for a Safer Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A novel thermos‐responsive hydroxypropyl cellulose/graphene oxide (HPC/GO) composite membrane is fabricated for reversible temperature‐gated ion transport in aqueous zinc‐ion batteries. Enabled by LCST‐driven structural transition, unimpeded ion diffusion at room temperature delivers high capacity, while elevated temperature suppresses transport; full ...
