Blocking effect of crystal–glass interface in lanthanum doped barium strontium titanate glass–ceramics

Effects of silica coating on the microstructures and energy storage properties of BaTiO 3 ceramics

“…In order to improve the dielectric breakdown strength, many methods have been adopted, such as controlling grain size [3,9,10], coating/mixing with low-melting point glass to remove the porosity [11][12][13][14][15][16], and forming new solid solutions with other compounds to reduce the polarization loss [17]. Among these, coating is a simple but effective method and can be operated at ambient temperature.…”

Boosting Energy Storage Performance of Glass Ceramics via Modulating Defect Formation During Crystallization

“…In this case, the peak frequencies of the ‐Z′′ and M′′ versus frequency plots should be close. [ 50 , 51 ] The plots of ‐Z′′ and M′′ versus frequency of the BTAS glass ceramic samples are given in Figure S6b–g (Supporting Information). Although in the all BTAS glass ceramic samples the differences in the peak frequencies between the ‐Z′′ and M′′ versus frequency plots does not show an apparent trend, the mismatch of the peak frequency found in the BTAS‐3 glass ceramic is still the smallest, which indicates that the BTAS‐3 glass ceramic has the minimum dielectric mismatch.…”

“…One root cause can be attributed to the strong interfacial polarization between glass and crystal grains which will deteriorates the DBS and the energy conversion efficiency (𝜂). [18][19][20] It should be noted that the superparaelectric relaxor ferroelectric strategy in dielectric film enlighten the important effect of paraelectric phase on improving dielectric energy storage performance. [3] Our previous work demonstrated a new strategy of precipitating paraelectric (cubic) BaTiO 3 phase from parent glass by traditional thermal treatment to achieve a high DBS in BaTiO 3 glass ceramic due to similar polarization natures between the paraelectric phase (crystal phase) and the linear dielectric (glass phase).…”

Influence of Anodic Oxidation Parameters of TiO2 Nanotube Arrays on Morphology and Photocatalytic Performance

“…Ever since carbon nanotubes were discovered by Iijima, nanomaterials with tube structure have attracted widespread attention from different research area due to its unique geometric structure and advanced physicochemical properties. As one of those nanotube materials, titanium dioxide nanotube arrays (TNTAs) have been applied to many fields, such as photocatalytic hydrogen generation, photovoltaic cells, degradation of organic contaminants, and gas sensor, because of their excellent specific surface area, high adsorption capacity, and less agglomeration [1][2][3][4][5][6][7][8][9][10][11][12][13]. Recently, multiple methods of preparation on TNTAs have been proposed: hydrothermal synthesis method, template method, and electrochemical anodic oxidation [14][15][16].…”
