Macroscopic Graphene Oxide Corrugated Structures

open access: yesAdvanced Materials Interfaces, EarlyView.
Various macroscopic 3D corrugated structures, including triangular corrugations, sinusoidal corrugations, and corrugated boards, are constructed from graphene oxide paper. These structures have smooth and compact surfaces and high geometrical precision.

3D Nanorod‐Shaped Binder‐Free Ni1−xFexCo2O4 Anodes Demonstrate High Performance and Stable Operation Under Accelerated Stress Tests in Anion Exchange Membrane Water Electrolysis

open access: yesAdvanced Materials Interfaces, EarlyView.
3D shaping of Ni1‐xFexCo2O4 spinel electrocatalyst to form high aspect ratio nanorods, made of 25 nm grain size particles and directly grown on Nickel felt, is proposed to improve the performance of industrial catalysts based on group‐VIII transition‐metal oxides.

Dental Microwear Texture Analysis on Radular Teeth

open access: yesAdvanced Materials Interfaces, EarlyView.
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.

Quantifying retinal blood vessels' tortuosity: review

open access: yes, 2017
Tortuosity of retinal blood vessels has been identified as one of earliest indicators to a number of vascular and nonvascular diseases; therefore, early detection and grading blood vessel tortuosity could help for early diseases prevention of further ...

Deep Eutectic Solvent‐Enhanced PEDOT: PSS/NR Foam Piezoresistive Sensor for High‐Sensitivity Wearable Devices and Sleep Monitoring Applications

open access: yesAdvanced Materials Interfaces, EarlyView.
A high‐performance piezoresistive foam sensor is developed by integrating natural rubber, PEDOT: PSS, and a deep eutectic solvent (DES). DES effectively detaches insulating PSS from PEDOT, dramatically amplifying electrical conductivity and sensitivity.

Smart Electrospun Nanofibers for Controlled Oil‐Water Separation

open access: yesAdvanced Materials Interfaces, EarlyView.
Stimuli‐responsive electrospun nanofibers are reviewed as advanced platforms for controlled oil/water separation. The effects of surface wettability, porous structure, and external stimuli, including pH, temperature, gas, and light, on separation performance are discussed.

A Geometry Model for Tortuosity of Streamtubes in Porous Media with Spherical

open access: yes, 2005
A geometry model for tortuosity of tortuous streamtubes in porous media with spherical particles is proposed based on the assumption that some particles in a porous medium are unrestrictedly overlapped and hence of different configurations.

An Informal Approach to Measuring Tortuosity

open access: yes, 2017
Tortuosity is an intuitive term used to describe paths on the plane that exhibit multiple twists and turns. It is used in a variety of applications as a measure of how much a path deviates from a straight line, especially to analyze images.

Eutectic Gallium‐Indium as a Potential Non‐Toxic Replacement in Mercury Intrusion Porosimetry

open access: yesAdvanced Materials Technologies, EarlyView.
A practical alternative to mercury intrusion porosimetry is presented using non‐oxidized eutectic gallium‐indium. An eGaIn Filling Station enables oxygen‐free preparation of standard penetrometers, and the resulting measurements faithfully reproduce pore‐size distributions and intrusion volumes measured with mercury across several standard reference ...
