Nanofillers to Improve the Barrier Properties of Biobased Substrates of Flexible Printed Electronics

Advanced Energy and Sustainability Research, Volume 7, Issue 8, August 2026.
Replacing the fossil‐based substrates of supercapacitors containing liquid electrolytes with biopolymers requires an improvement in their barrier properties. Here, the abilities of three different nanofillers to lower the permeabilities of biopolymers are investigated. 20 w‐% of nanoclay Nanomer I.28E mixed into polyhydroxybutyrate has the best barrier

Validation of ultrasonic velocity estimates of wood properties in discs of radiata pine

New Zealand Journal of Forestry Science, 2017
Background Measurement of microfibril angle (MFA) in the S2 layer of the cell walls of wood using speed of sound in wood has become a common way to estimate wood stiffness and stability. Measurements across the radius of a disc can be critical, but sonic

Relationships between microfibril angle, modulus of elasticity and compressive strength in Eucalyptus wood

Maderas: Ciencia y Tecnología, 2014
Many traits are known to be important in determining the value of Eucalyptus wood as sawn tim-ber. The commercial importance of the microfi bril angle (MFA) for wood quality is well established for a range of softwoods, but is less clear for hardwood ...

Lodging Variability in Sorghum Stalks Is Dependent on the Biomechanical and Chemical Composition of the Stalk Rinds

Crops
Stalk lodging contributes to significant crop yield losses. Therefore, understanding the biomechanical strength and structural rigidity of grain stalks can contribute to improving stalk lodging resistance in crops. From the structural constituents of the
