Single-Crystal P2-NaMnNiO Cathode Material with Improved Cycling Stability for Sodium-Ion Batteries.

Layered oxides constitute one of the most promising cathode materials classes for large-scale sodium-ion batteries because of their high specific capacity, scalable synthesis, and low cost. However, their practical use is limited by their low energy density, physicochemical instability, and poor cycling stability. Aiming to mitigate these shortcomings, in this work, we synthesized polycrystalline (PC) and single-crystal (SC) P2-type NaMnNiO (NMNO) cathode materials through a solid-state route and evaluated their physicochemical and electrochemical performance.

A Rare Condition of Ameloblastoma Transforming into Ameloblastomic Carcinoma - A Case Report.

Rationale: Ameloblastic carcinoma is defined as an ameloblastoma in which there is histological evidence of malignancy in primary tumour or recurrent tumour regardless if it has metastasised or not. It is aggressive in nature.

Patient Concerns: The patient presented with a painful swelling associated with restricted mouth opening.

Greener, Safer and Better Performing Aqueous Binder for Positive Electrode Manufacturing of Sodium Ion Batteries.

P2-type cobalt-free MnNi-based layered oxides are promising cathode materials for sodium-ion batteries (SIBs) due to their high reversible capacity and well chemical stability. However, the phase transformations during repeated (dis)charge steps lead to rapid capacity decay and deteriorated Na diffusion kinetics. Moreover, the electrode manufacturing based on polyvinylidene difluoride (PVDF) binder system has been reported with severely defluorination issue as well as the energy intensive and expensive process due to the use of toxic and volatile N-methyl-2-pyrrolidone (NMP) solvent.

MnO nano-octahedrons embedded in nitrogen-doped graphene oxide as potent anode material for lithium-ion batteries.

Unlabelled: MnO nano-octahedrons embedded in N-doped graphene oxide (MNGO) nanosheets were synthesized using a simple, energy-efficient, and rapid microwave-digested hydrothermal route in a single step. The structural and morphological aspects of synthesized materials were evaluated by XRD, IR, Raman, FE-SEM, and HR-TEM techniques. Then, the composite MNGO was tested for its Li-ion storage properties and compared with reduced graphene oxide (rGO) and MnO materials.

Management of Alveolar Cleft Defect by Iliac Crest Secondary Bone Grafting: A Case Report.

Aim And Objective: This case report aims to describe the management of alveolar cleft defect by iliac crest secondary bone grafting.

Background: The secondary alveolar bone grafting performed during the mixed dentition period is an essential module of modern-day rehabilitation of cleft lip and palate patients with alveolar defects. Iliac crest bone graft is a frequent secondary graft used and is technique sensitive.
