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 ...

Correlation between drying defects, their parameters and moisture gradient in kiln-dried, south african grown Eucalyptus Grandis poles

open access: yesMaderas: Ciencia y Tecnología, 2014
Non-destructive testing for drying defects in Eucalyptus grandis utility poles would be highly advantageous. These defects can negatively affect creosote preservative treatment and in-service performance.

Drying characteristics of wood of invasive tree species growing in an urban environment

open access: yesLes, 2019
Non-native tree species are increasingly growing in urban environments, where they are exposed to cultivation and pruning measures, and in many cases their growth becomes uncontrolled, even invasive.

Structural Power Composites Based on High Mass Loading Zn‐Ion Hybrid Supercapacitors with Metal Mesh Current Collectors and Aramid Nanofiber/Glass Fiber Composite Electrolytes

open access: yesAdvanced Functional Materials, EarlyView.
A multifunctional structural power composite is developed by integrating high‐mass‐loading Zn‐ion hybrid supercapacitors with metal mesh current collectors and aramid nanofiber‐based composite electrolytes, enabling simultaneous load‐bearing capability and enhanced areal energy storage.

Water Vapor Emission From Rigid Mesoporous Materials during the Constant Drying Rate Period

open access: yes, 2012
It has long been thought that the evaporation rate from mesoporous materials during the constant drying rate period (CDRP) is equal to that of a free-water surface, due to the presence of a liquid film covering the surface of the material.

SIFAT PENGERINGAN ALAMI DAN PENGERINGAN SINAR MATAHARI

open access: yesJurnal Penelitian Hasil Hutan (Journal of Forest Products Research), 2017
The study reported here concerns the drying rate expressed in daily moisture content decrease and the associated defects. Based on moisture content decrease data, the wood species studied were grouped into 3 classes, namely  easy,  moderately  easy  and

Tough and Skin‐Free Porous Polyelectrolyte Complex Hydrogels via Salt‐Induced Aqueous Phase Separation

open access: yesAdvanced Functional Materials, EarlyView.
Controlling counterion exchange rate during aqueous phase separation enables the formation of skin‐free, homogeneously porous polyelectrolyte complex hydrogels by suppressing kinetically trapped skin layers and macrovoids. The resulting hydrogel networks exhibit exceptional toughness (∼15 MJ·m−3) and enable 3D (bio)printing and post‐functionalization ...

Drying of Heat Sensitive Materials of High Moisture Content in Mechanically Spouted Bed of Inert Particles [PDF]

open access: yes, 2008
In drying operation the material characteristics such as heat sensitivity, moisture content and particle size are of great importance, which should be taken into account in selection of proper design and conditions for the process.

Noise‐Limited Bit Precision in Ferroelectric Synaptic Transistors for High‐Resolution Neuromorphic Computing

open access: yesAdvanced Functional Materials, EarlyView.
Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...
