Recent advances of ferro-/piezoelectric polarization effect for dendrite-free metal anodes

Functional dielectric materials for high-performance solid-state batteries

“…The dielectric effect reduces the ion concentration gradient around the lithium metal by adjusting the ion distribution, thereby forming a uniform deposition. 156 As depicted in Fig. 9(a), a high dielectric SEI layer can homogenize the electric field at the interface and reduce high current density in localized areas, thereby reducing the overall interfacial overpotential.…”

Tailored Double Perovskite with Boosted Oxygen Reduction Kinetics and CO2 Durability for Solid Oxide Fuel Cells

“…14,15 However, Srdoped LnBaCo 2 O 5+δ double perovskites still suffer from high thermal expansion coefficients compared with conventional electrolyte materials. 16,17 The substantial thermal expansion coefficient (TEC) mismatch between LnBaCo 2 O 5+δ cathodes and electrolytes could affect the SOFC stability due to the cyclic thermal treatments. The large TECs of LnBaCo 2 O 5+δ are ascribed to the presence of cobalt ions, including their transition of spin states and weak bonds with oxygen.…”

“…LnBaCo 2 O 5+δ (Ln = lanthanide element) double perovskites have been investigated as potential SOFC cathodes . Research findings indicate that substituting Ba with Sr effectively improves the conductivity of LnBaCo 2 O 5+δ . , However, Sr-doped LnBaCo 2 O 5+δ double perovskites still suffer from high thermal expansion coefficients compared with conventional electrolyte materials. , The substantial thermal expansion coefficient (TEC) mismatch between LnBaCo 2 O 5+δ cathodes and electrolytes could affect the SOFC stability due to the cyclic thermal treatments.

Electrochemical detection of kynurenic acid in the presence of tryptophan with the carbon paste electrode modified with the flower-like nanostructures of zinc oxide doped with terbium

“…Researchers mentioned disadvantages such as laborious analysis, costly processes, complications, exposure to diverse interferences, derivatization reactions, and pollution ( Maaref et al, 2018 ; Farvardin et al, 2020 ; Zheng et al, 2020 ; Jahani et al, 2022 ; Tang et al, 2022 ; Zhang et al, 2023 ; Ren et al, 2023 ; Özcan et al, 2023 ). It was demonstrated that electrochemical approaches are efficient analytical procedures with the following characteristics: easy to use, rapid response, inexpensiveness, and portability ( Akbari et al, 2020 ; Iranmanesh et al, 2020 ; Moarefdoust et al, 2021 ; Antherjanam and Saraswathyamma, 2022 ; Zhang et al, 2023 ; Cai et al, 2023 ; Tang et al, 2023 ; Wan et al, 2023 ). In fact, scholars have increased the sensitivity for detecting the electroactive analytes using chemical modifiers and a wide range of nanomaterials have been applied to determine the analytes ( Wu et al, 2023 ; Kambale and Lokhande, 2023 ; Zhao et al, 2023 ; Taherizadeh et al, 2023 ; Guo et al, 2023 ; Ghasemi et al, 2023 ).…”
