A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

Advanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

Hydrothermal preparation of highly tetragonal BaTiO3 nanopowders for ultra-thin multilayer ceramic capacitors

Journal of Advanced Dielectrics
BaTiO3 nanopowders with high tetragonality ([Formula: see text] are essential for fabricating ultra-thin multilayer ceramic capacitors (MLCCs). The hydrothermal method commonly employed in the industry presents challenges in synthesizing BaTiO3 ...

Morphology and Dielectric Properties of Boron-doped BaTiO3

High Temperature Materials and Processes, 2013
Boron-doped BaTiO3 precurors (BaTi1−xB2xO3+X) were prepared via the glycol-glycerol complexes of boron, titanium (IV), and barium. With optimum composition, ceramics with dielectric properties comparable to those of pristine BaTiO3 ceramic sintered at ...

Dispersion of nano-sized BaTiO3 powders in nonaqueous suspension with phosphate ester and their applications for MLCC

, 2010
The stability of nano-sized BaTiO3 nonaqueous suspension with different phosphate ester surfactants was investigated. Among the three phosphate esters (mono-alkyl, di-alkyl and ethoxy types), the 2-ethoxy ethyl dihydrogen (1EO-) phosphate esters show not

Dual‐Physical‐Field Nanocatalysis: Injectable Hydrogel Enables Piezo‐Photothermal Synergy for Breast Cancer Therapy

Advanced Science, EarlyView.
ABSTRACT Piezocatalytic therapy (PCT) harnesses mechanical energy to generate tumor‐lethal reactive oxygen species (ROS), but its efficacy is limited by rapid electron‐hole recombination and poor intratumoral retention. To overcome these limitations, we engineered heterostructured BiOCl@CuO nanosheets embedded in an injectable, conductive ...

Origin of thermally stable ferroelectricity in a porous barium titanate thin film synthesized through block copolymer templating

APL Materials, 2017
A porous barium titanate (BaTiO3) thin film was chemically synthesized using a surfactant-assisted sol-gel method in which micelles of amphipathic diblock copolymers served as structure-directing agents.

Electrical Properties of Un-doped and Doped EuTiO3-based Perovskites [PDF]

, 2013
Un-doped and doped EuTiO3 (ET) ceramics were prepared in 5%H2/95%N2 and N2 atmospheres at various temperatures (1350, 1450 and 1500 oC). For un-doped ET, higher pellet density (above 90%) and larger grain sized ceramics were obtained from the higher ...
