Influence of pH-control in phosphoric acid treatment of zinc oxide

open access: yesCerâmica
Zinc oxide is often used as a white pigment for cosmetics; however, it shows photocatalytic activity that causes decomposition of sebum on the skin when exposed to the ultraviolet radiation in sunlight.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

open access: yesAdvanced 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 ...

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

Effect of nano zinc oxide on physical and mechanical properties of wood plastic composites [PDF]

open access: yesIranian Journal of Wood and Paper Industries, 2017
In this study, the effects of nano zinc oxide on the physical and mechanical properties of wood-polyethylene composites were investigated. The composites containing 0, 1, 2 and 4 wt% zinc oxide nanoparticles were manufactured using an internal mixer and ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

open access: yesAdvanced Functional Materials, EarlyView.
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.

Antibacterial property of eugenol and eugenol-free zinc oxide cements incorporated with various concentrations of sodium fluoride

open access: yesAdvances in Human Biology, 2018
Background: Restoring tooth by fixed partial dentures involves tooth reduction to reproduce the dental anatomy in the prosthesis. This process brings about the exposure of millions of dentinal tubules which serves as potential passageways for the ...
