Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Selective Determination of Pyridoxal with an Octadecylamine- Modified Carbon-Paste Electrode

Analytical Sciences, 1991
A carbon-paste electrode containing octadecylamine was used for voltammetric determination of pyridoxal in aqueous solutions. After chemical deposition of pyridoxal on the modified electrode through Schiff base formation, differential pulse voltammetry exhibited a well-developed reduction wave at +0.52V vs.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
