Facile synthesis of ultrafine and high purity spherical strontium carbonate via gas-liquid reaction

Materials Research Express, 2020
In this work, a simple gas-liquid precipitation reaction was developed to fabricate spherical strontium carbonate (SrCO _3 ) particles using strontium hydroxide (Sr(OH) _2 ), carbon dioxide (CO _2 ) and ethylene diaminetetraacetic acid strontium salt ...

Resolving Nanoscale Heterogeneities in Lead Halide Perovskites Through Low‐Dose Concurrent 4D‐STEM‐EDX Mapping

Advanced Materials, EarlyView.
Mixed‐cation lead mixed‐halide perovskites suffer from structural instabilities linked to nanoscale heterogeneity. To probe this non‐destructively, a low‐dose, concurrent 4D‐STEM and EDX methodology has been developed. Examining a (FA0.83Cs0.17)Pb(I0.8Br0.2)3 film revealed a complex mosaic of coexisting crystal structures. Crucially, local deficiencies

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

Advanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Synthesis of strontium and barium cerate and their reaction with carbon dioxide

Solid State Ionics, 1993
Abstract The log pCO2 versus 1/T relationships of the equilibria (1) ACO3+CeO2⇆ACeO3+CO2 and ACO3⇆+CO2 in whi ch A = Sr or Ba, were investigated. The methods which have been used are: thermodynamic equilibrium calculations, simultaneous thermogravimetry-differential thermal analysis and high-temperature X-ray diffraction.

Directional Latent Hybridization: Beyond Random Noise in Physics‐Informed Generative Inverse Design of Nonlinear Metamaterials

Advanced Materials Technologies, EarlyView.
A physics‐informed generative framework introduces Directional Latent Hybridization (DLH) for the deterministic inverse design of nonlinear metamaterials. By hybridizing dominant traits from parent geometries in the latent space, DLH overcomes the instabilities of stochastic models to ensure high structural precision at high densities.

Energy‐Transfer‐Driven Programmable Luminescence in Bi3+‐Eu3+ Co‐Doped Na3Ca2TaO6 Phosphors Toward Multifunctional Optical Applications

Advanced Optical Materials, EarlyView.
Energy transfer from broadband Bi3+ sensitizers to Eu3+ emitters enables composition‐, excitation‐, and temperature‐dependent luminescence in Na3Ca2TaO6. These controllable optical states support ratiometric thermometry and excitation‐selective, filter‐assisted information decoding in flexible phosphor–polydimethylsiloxane films, demonstrating how ...
