There is great interest in lead-free $(\mathrm{B}{\mathrm{a}}_{0.85}\mathrm{C}{\mathrm{a}}_{0.15})(\mathrm{T}{\mathrm{i}}_{0.90}\mathrm{Z}{\mathrm{r}}_{0.10}){\mathrm{O}}_{3}$ (15/10BCTZ) because of its exceptionally large piezoelectric response [Liu and Ren, Phys. Rev. Lett. 103, 257602 (2009)]. In this paper, we have analyzed the nature of: (i) crystallographic phase coexistence at room temperature, (ii) temperature- field-induced transformation to throw light on atomistic mechanisms...
Preparation of Ce–Zn substituted barium hexaferrites and investigation their magnetic behavior in low temperature regime (2–300 K).
Flexible and high-performance batteries are urgently required for powering flexible/wearable electronics. Lithium–sulfur with a very high energy density promising candidate high-energy-density flexible power source. Here, we report lithium–sulfur full cells consisting of ultrastable lithium cloth anodes, polysulfone-functionalized separators, free-standing sulfur/graphene/boron nitride nanosheet cathodes. The carbon decorated lithiophilic three-dimensional MnO2 nanosheets not only provides...
Among the various oxide thermoelectric materials, double perovskites provide more flexibility to maneuver interdependent parameters achieve enhanced figure of merit (ZT), as octahedral ordering, i.e., arrangement ${B}^{\ensuremath{'}}{\mathrm{O}}_{6}$ and ${B}^{\ensuremath{''}}{\mathrm{O}}_{6}$ octahedra, present in ${A}_{2}{B}^{\ensuremath{'}}{B}^{\ensuremath{''}}{\mathrm{O}}_{6}$ structure is impacted by cation doping. In this work, we investigated role distortion on properties...
Metal–organic framework (MOF) nanostructures provide unique opportunities in the fabrication of multifunctional polymer nanocomposites. However, achieving both enhanced mechanical properties and fire safety using labile metal–organic reinforced epoxy composites is usually challenging, calling for post-synthetic modification (PSM) MOFs. In this study, we have synthesized an organophosphorus functionalized zirconium-based MOF, P-UiO-66 NH2 (P-MOF). This as-synthesized modified MOF when with...
Environmental friendly, non-toxic double perovskite BaxSr2-xTiCoO6 compositions with 0 ≤ x 0.2 were synthesized using solid-state reaction route for high temperature thermoelectric (TE) applications. XRD and SEM studies confirmed the presence of single-phase solid solution highly dense microstructure all oxide compositions. Temperature dependent electrical conductivity measurement showed semiconductor to metal (M-S) transition in these perovskites. Incorporation barium Sr2TiCoO6 pushed M-S...

In general, n-type thermoelectric materials are rather difficult to design. This study particularly pivoted on designing potential environmentally benign oxides based material. We synthesized Sr2CoMoO6 (SCMO) polycrystalline ceramics via the solid-state synthesis route. XRD, SEM, and measurements were carried out for phase constitution, microstructure analysis, determine its applications. As-sintered SCMO sample showed an insulator like behavior till 640 °C after which it exhibited...
Interfacial issues and dendritic Li deposition in lithium metal batteries (LMBs) hamper the practical application of liquid or solid-state cells. Here, a hybrid solid electrolyte interphase (SEI), based on hydroxyl-functionalized boron nitride (BN) nanosheets poly(vinyl alcohol), is designed to solve unstable nature anode-electrolyte interface. Rather than acquiring rich halide environment through intense decomposition, SEI effectively regulates decomposition guarantees uniform plating via...
Current Li-ion batteries have a low energy density mainly because of the Li intercalation level in graphite anodes. The high-density packing lithium atoms electrode materials amplifies storage capacity and efficiency devices. use two-dimensional (2D) bilayer structures offers an immediate advantage compared to conventional electrodes. However, 2D homostructures heterostructures is still limited. In present theoretical study, we modified by creating controlled point defects. Using ab initio...
Realizing Von Hove singularity (VHS) and extended flat bands of graphene near the Fermi level ( E F ) to explore many-body interactions with a high tendency towards superconductivity.
Manganites had been proposed as one of the potential n-type oxide materials to develop thermoelectric power generators. In present investigation, we studied structural and properties Gd1-xSrxMnO3 (GSMO) (0.5 ≤ x 0.8) polycrystalline ceramics synthesized by a conventional solid-state route. Rietveld refinement XRD patterns revealed distorted orthorhombic Pbnm crystal structure in all compositions. The decrease J-T distortions, on Gd-rich side GSMO (x 0.6), due favored formation Mn4+ was...
The wearable electronics and nanorobotics demand high energy density devices such as thin-film solid-state lithium-sulfur (Li-S) or lithium-metal polysulfide (Li-MSx) batteries on a small footprint area, which requires the adoption of modern fabrication technologies. efficient sulfur based thin film cathodes for Li-MSx is serious challenge because insulating nature low meting point sulfur. Herein, we have developed highly conductive amorphous SbSxCy+z with chemically bonded by adopting...
