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 ...

What Can the Concept of a Perfect Chemoelastic Solid Tell us about the Mechanical and Thermodynamic Behaviour of a Solid ?

Le Journal de Physique IV, 1996
The elastic energy stored in a solid is typically small compared to the energy involved in a phase change. As a consequence, it is relatively easy to generate elastic stresses by a modification of the composition andor a phase transformation. Conversely, the influence of stresses on phase changes is only of importance in special situations.

Simple thermodynamic model of the extension of solid solution of Cu–Mo alloys processed by mechanical alloying

Materials Chemistry and Physics, 2011
Abstract The objective of this work is proposing a simple thermodynamic model to explain the increase in the solubility limit of the powders of the Cu–Mo systems or other binary systems processed by mechanical alloying. In the regular solution model, the effects of crystalline defects, such as; dislocations and grain boundary produced during milling ...

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Electrostatic Superlattices Beyond 1:1 Stoichiometry

Advanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Thermodynamic explanation of solid-state reactions in synthesis process of CoSb3 via mechanical alloying

Acta Physica Sinica, 2006
CoSb3 powders were synthesized by mechanical alloying (MA) with Co and Sb powders as starting materials. The influence of milling speed and duration on the solid reaction were systematically studied. The XRD results indicated that the CoSb3 phase increased with prolonged MA-time, but extensive MA resulted in the appearance of CoSb2 and the ...

The laws of thermodynamics deduced from statistical mechanics

, 2004
Since the advent of statistical mechanics, the laws of thermodynamics are consequences of more fundamental postulates. Nevertheless, the logical link between statistical mechanics and thermodynamics is far from being precisely described in the literature,

Chitin‐Derived Carbon‐Metal Functional Materials

Advanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.
