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 ...

Molecular Rotors: From Newtonian Fluids to Functional Materials as Viscosity and Temperature Sensing Tools

Advanced Functional Materials, EarlyView.
Molecular rotors are fluorescent molecules that are sensitive to viscosity and temperature variations in the environment. They exhibit a direct correlation between fluorescence and viscosity within Newtonian fluids. However, this correlation becomes less straightforward in complex systems.

Fiber‐reinforced Liquid Metal Composites With Automated Circuit Fabrication for Structurally‐Integrated Power Transfer

Advanced Functional Materials, EarlyView.
Fiber‐reinforced liquid metal composites (FibRe LMCs) are introduced that combine GPa‐scale structural performance with digitally programmable electrical conductivity. Through automated CNC activation, conductive pathways and wireless power transfer circuits are fabricated directly within load‐bearing composites, enabling structurally integrated ...

Electromagnetic Properties of Unstable Particles [PDF]

Il Nuovo Cimento, 1962
Charge and current distributions are defined for unstable particles in no-recoil theories. They are in general complex, and oscillate with amplitudes increasing exponentially at large distances. Moments can be defined nevertheless. As with stable particles, electric dipole moments are necessarily zero if time reversibility holds.
