Knoop micro-hardness studies on (110) surface of gel grown strontium tartrate di-hydrate crystal [PDF]
The wedge shape or elongated pyramid Knoop indenter is preferred for micro-hardness anisotropy study. In the Knoop indenter, the width, volume or projected area of the indentation mark can be used as a measure of hardness by aligning the indenter ...

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.
