Hydrothermal Synthesis of β-NiS Nanoparticles and Their Applications in High-Performance Hybrid Supercapacitors.

In this work, β-NiS nanoparticles (NPs) were efficiently prepared by a straightforward hydrothermal process. The difference in morphology between these NiS NPs was produced by adding different amounts of thiourea, and the corresponding products were denoted as NiS-15 and NiS-5. Through electrochemical tests, the specific capacity () of NiS-15 was determined to be 638.

High-performance asymmetric supercapacitors assembled with novel disc-like MnCoO microstructures as advanced cathode material.

Herein, porous MnCoO with disc-like (MnCoO-discs) and ring-like (MnCoO-rings) microstructures were respectively synthesized using an initial hydrothermal method at different temperatures and a calcination treatment in air. The electrochemical properties of these MnCoO materials were investigated in three-electrode and two-electrode systems, and as such, MnCoO presented a battery-like electrochemical response. The specific capacity of MnCoO-discs was determined to be 296.

Sonochemical synthesis of CoNi layered double hydroxide as a cathode material for assembling high performance hybrid supercapacitor.

Fabricating battery-type electrode materials with large specific surface area and mesopores is an efficient method for enhancing the electrochemical performance of supercapacitors. This method may provide more active sites for Faradic reactions and shorten the ion-diffusion paths. In this study, the CoNi layered double hydroxides (LDHs) with the morphology of nanoflowers and nanoflakes were prepared in solutions with pH values of 7.

Analysis of Competitive Endogenous Mechanism and Survival Prognosis of Serum Exosomes in Ovarian Cancer Patients Based on Sequencing Technology and Bioinformatics.

We determined the competitive endogenous in serum exosomes of ovarian cancer patients sequencing technology and raw signal analysis. We performed an in-depth study of the potential mechanisms of ovarian cancer, predicted potential therapeutic targets and performed survival analysis of the potential targets. Serum exosomes from three ovarian cancer patients were used as the experimental group, serum exosomes from three patients with uterine fibroids were used as the control group, and whole transcriptome analysis of serum exosomes was performed to identify differentially expressed long noncoding RNAs (lncRNAs) and mRNAs in ovarian cancer.

Nanosheet-assembled porous MnCoO microflowers as electrode material for hybrid supercapacitors and lithium-ion batteries.

Herein, the MnCoO microflowers (MFs) assembled by two-dimensional (2D) porous nanosheets were prepared through an initial solvothermal reaction with a subsequent annealing process. In this architecture, many interconnected 2D thin nanosheets were self-assembled together to form a 3D hierarchical MF with plenty of open channels. Such structure endows these MnCoO MFs with large specific surface area of 156.

Porous MgCoO nanoflakes serve as electrode materials for hybrid supercapacitors with excellent performance.

In this work, MgCoO microspheres (MgCoO MSs) and MgCoO nanoflakes (MgCoO NFs) were prepared by one-step and two-step synthetic method, respectively, and combined with a post annealing treatment. Both MSs and NFs electrode materials possessed porous structure and large specific surface areas. The electrochemical properties were evaluated using three-electrode as well as two-electrode systems.

Uniform MnCoO porous nanowires and quasi-cubes for hybrid supercapacitors with excellent electrochemical performances.

In this work, uniform MnCoO nanowires (NWs) on stainless steel foil (SSF) were prepared through a facile, cost-efficient, and eco-friendly hydrothermal method at 120 °C with a post-calcination process in air. The microstructure of MnCoO samples could be tuned at different hydrothermal temperatures and quasi-cubes (QCs) were obtained in high yield at 150 °C. The MnCoO NW powder peeled off from the SSF delivered an outstanding capacity of 248.

Egg Albumin-Assisted Hydrothermal Synthesis of CoO Quasi-Cubes as Superior Electrode Material for Supercapacitors with Excellent Performances.

Novel CoO quasi-cubes with layered structure were obtained via two-step synthetic procedures. The precursors were initially prepared via hydrothermal reaction in the presence of egg albumin, and then the precursors were directly annealed at 300 °C in air to be converted into pure CoO powders. It was found that the size and morphology of final CoO products were greatly influenced by the amount of egg albumin and hydrothermal durations, respectively.
