All‐Aqueous Pullulan Fibers Enabling Visible‐to‐Near‐Infrared Waveguiding with Mechanical and Thermal Resilience

open access: yesAdvanced Functional Materials, EarlyView.
Pullulan, a biomass‐derived polysaccharide, is transformed into transparent optical fibers using a solvent‐free borax hydrogel‐spinning method. The fibers outperform PMMA with ≈200 MPa tensile strength and 200 °C stability, while uniquely guiding visible‐to‐NIR light and enabling additive‐free humidity sensing.

From Mechanics to Electronics: Influence of ALD Interlayers on the Multiaxial Electro‐Mechanical Behavior of Metal–Oxide Bilayers

open access: yesAdvanced Functional Materials, EarlyView.
Ultrathin AlOxHy interlayers between aluminum films and polymer substrates significantly improve electro‐mechanical properties of flexible thin film systems. By precisely controlling interlayer thickness using atomic layer deposition, this study identifies an optimal interlayer thickness of 5–10 nm that enhances ductility and delays cracking.

Processing of advanced Al/SiC particulate metal matrix composites under intensive shearing – A novel rheo process [PDF]

open access: yes, 2008
Particulate Metal Matrix Composites (PMMCs) have attracted interest for application in numerous fields. The current processing methods often produce agglomerated particles in the ductile matrix and as a result these composites exhibit extremely low ...

PREDICTION OF STRAND FEEDSTOCK MECHANICAL PROPERTIES WITH NEAR INFRARED SPECTROSCOPY

open access: yesBioResources, 2012
Wood strands either prepared in the laboratory or from a manufacturing plant were assessed for their ultimate tensile strength, tensile MOE, bending strength, and bending stiffness, and then near infrared spectroscopy was utilized for prediction.

Analysis of Tensile Strength’s Influence on Limit Height and Active Earth Pressure of Slope Based on Ultimate Strain Method

open access: yesAdvances in Materials Science and Engineering, 2017
In the geotechnical engineering, the tensile failure of soil is disregarded for a long time. Actually, the tensile strength of soil is very low and the tensile failure really occurs, especially in the slope engineering.
