Graded Hydroxyapatite Triply Periodic Minimal Surface Structures for Bone Tissue Engineering Applications

open access: yesAdvanced Healthcare Materials, EarlyView.
This study investigates the role of triply periodic minimal structures in load bearing bone tissue engineering applications. Research uses a combination of mechanical testing, material characterization, and in vitro tests to study the impact of TPMS lattice structures (gyroid, lidinoid and split‐P).

Synthesis and Characterization of Strontium Carbonate Nanostructures via Simple Hydrothermal Method

open access: yesHigh Temperature Materials and Processes, 2016
Strontium carbonate (SrCO3) nanostructures were synthesized via simple hydrothermal method by Sr(NO3)2, ethylenediamine and hydrazine as reagents. The products were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), energy ...

Rapid Surface Reconstruction of In2S3 Photoanode via Flame Treatment for Enhanced Photoelectrochemical Performance

open access: yesAdvanced Materials, EarlyView.
A rapid surface reconstruction strategy is proposed to enhance the charge collection efficiency and stability of indium sulfide (In2S3) photoanode via a high‐temperature flame treatment. This method selectively transforms the In2S3 surface into a diffusionless In2O3 and generates bulk sulfur vacancies, resulting in surface‐reconstructed In2S3 (sr‐In2S3)

Strategies for Controlling Emission Anisotropy in Lead Halide Perovskite Emitters for LED Outcoupling Enhancement

open access: yesAdvanced Materials, EarlyView.
The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...

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

open access: yesSolid 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.
