AbstractSodium ion batteries and capacitors have demonstrated their potential applications for next-generation low-cost energy storage devices. These devices's rate ability is determined by the fast sodium ion storage behavior in electrode materials. Herein, a defective TiO2@reduced graphene oxide (M-TiO2@rGO) self-supporting foam electrode is constructed via a facile MXene decomposition and graphene oxide self-assembling process. The employment of the MXene parent phase exhibits distinctive advantages, enabling defect engineering, nanoengineering, and fluorine-doped metal oxides. As a result, the M-TiO2@rGO electrode shows a pseudocapacitance-dominated hybrid sodium storage mechanism. The pseudocapacitance-dominated process leads to high capacity, remarkable rate ability, and superior cycling performance. Significantly, an M-TiO2@rGO//Na3V2(PO4)3 sodium full cell and an M-TiO2@rGO//HPAC sodium ion capacitor are fabricated to demonstrate the promising application of M-TiO2@rGO. The sodium ion battery presents a capacity of 177.1 mAh g−1 at 500 mA g−1 and capacity retention of 74% after 200 cycles. The sodium ion capacitor delivers a maximum energy density of 101.2 Wh kg−1 and a maximum power density of 10,103.7 W kg−1. At 1.0 A g−1, it displays an energy retention of 84.7% after 10,000 cycles.

Recently, multivalent aqueous calcium-ion batteries (CIBs) have attracted considerable attention as a possible alternative to Li-ion batteries. However, traditional Ca-ion storage materials show either limited rate capabilities and poor cycle life or insufficient specific capacity. Here, we tackle these limitations by exploring materials having a large interlayer distance to achieve decent specific capacities and one-dimensional architecture with adequate Ca-ion passages that enable rapid reversible (de)intercalation processes. In this work, we report the high-yield, rapid, and low-cost synthesis of 1D metal oxides MV3O8 (M=Li, K), CaV2O6, and CaV6O16·7H2O (CVO) via a molten salt method. Firstly, using 1D CVO as electrode materials, we show high capacity 205 mA h g-1, long cycle life (>97% capacity retention after 200 cycles at 3.0 C), and high-rate performance (117 mA h g-1 at 12 C) for Ca-ion (de)intercalation. This work represents a step forward for the development of the molten salt method to synthesize nanomaterials and to help pave the way for the future growth of Ca-ion batteries.

Introduction: Helicobacter pylori eradication remains a problematic issue. We are in an urgent need for finding a treatment regimen that achieves eradication at a low cost and less side effect. Recent published results showing a high rate of resistance and with clarithromycin-based treatment regimens. The aim of the study was to compare moxifloxacin therapy and classic clarithromycin triple therapy in H. pylori eradication. Methods: This was a pilot study that enrolled 60 patients with helicobacter pylori associated gastritis. Diagnosis was done by assessment of H. pylori Ag in the stool. The patients were randomly assigned to receive either moxifloxacin based therapy (Group A), or clarithromycin based therapy (Group B) for two weeks. We stopped the treatment for another two weeks then reevaluation for cure was done. Results: 90 % of patients had negative H. pylori Ag in the stool after 2 weeks of stoppage of the treatment in group A versus 66.7 % in Group B. None of the patients in both groups had major side effects. Conclusion: Moxifloxacin-based therapy showed higher eradication power and less resistance when compared to clarithromycin triple therapy.
