Designing Crystalline/Amorphous NVNPF/NCK Cathode Toward High-Performance Fully-Printed Flexible Aqueous Rechargeable Sodium-Ion Batteries (ARSIBs).

The flexible ARSIBs have great potential in portable and wearable electronics due to their high cost-effectiveness, safety, and amazing flexibility. Nevertheless, achieving both outstanding flexibility and high energy density remains a challenge. Herein, a battery-supercapacitor composite material NaVNi(PO)F/10%NC-KOH (NVNPF/NCK) with coexistence of crystalline and amorphous phases is fabricated by loading nitrogenous carbon (NC) onto NaVNi(PO)F (NVNPF) and etching with KOH.

Fully Printable Manufacturing of Miniaturized, Highly Integrated, Flexible Evaporation-Driven Electricity Generator Arrays.

Harvesting sustainable clean energy from natural water evaporation holds great promise to provide continuous power for portable and wearable electronics. However, poor portability and complex fabrication processes hinder the low-cost and large-scale integration of flexible evaporation-driven electricity generators (FEEGs). Herein, a fully-printed flexible evaporation-driven generator (PFEEG) is developed.

Fully-Printed Flexible Aqueous Rechargeable Sodium-Ion Batteries.

The flexible aqueous rechargeable sodium-ion batteries (ARSIBs) are a promising portable energy storage system that can meet the flexibility and safety requirements of wearable electronic devices. However, it faces huge challenges in mechanical stability and facile manufacturing processes. Herein, the first fully-printed flexible ARSIBs with appealing mechanical performance by screen-printing technique is prepared, which utilizes NaV(PO)F/C (NVPF/C) as the cathode and 2% nitrogenous carbon-loaded NaMnTi(PO)/C (NMTP/C/NC) as the anode.

Ovarian toxicity of e-cigarette liquids: Effects of components and high and low nicotine concentration e-cigarette liquid .

Introduction: Electronic cigarette use has become increasingly popular, with potential consequences for reproductive health. We aimed to investigate the effects of different components of e-liquid on the ovary and compare the impact of low nicotine concentration e-liquids (LN e-liquids) and high nicotine concentration e-liquids (HN e-liquids) on ovarian toxicity.

Methods: A total of 378 rat ovaries were divided into seven groups, including control (no intervention), nicotine (0.

Oocyte Arrested at Metaphase II Stage were Derived from Human Pluripotent Stem Cells in vitro.

Initiation of meiosis is the most difficult aspect of inducing competent oocytes differentiation from human stem cells in vitro. Human induced pluripotent stem cells (hiPSCs) and embryonic stem cells (hESCs) were cultured with follicle fluid, cytokines and small molecule to induced oocyte-like cells (OLCs) formation through a three-step induction procedure. Expression of surface markers and differentiation potential of germ cells were analyzed in vitro by flow cytometry, gene expression, immunocytochemistry, western blotting and RNA Sequencing.

Optimized study of an 3D culture of preantral follicles in mice.

Background: culture of preantral follicles is a promising technology for fertility preservation.

Objectives: This study aims to investigate an optimized three-dimensional (3D) fetal bovine serum (FBS)-free preantral follicle culture system having a simple and easy operation.

Methods: The isolated follicles from mouse ovaries were randomly divided in an ultra-low attachment 96-well plates supplement with FBS or bovine serum albumin (BSA) culture or encapsulated with an alginate supplement with FBS or BSA culture.

Cistanche deserticola polysaccharides extracted from Cistanche deserticola Y.C. Ma promote the differentiation of mouse female germline stem cells in vitro.

Ethnopharmacological Relevance: Traditional Chinese herbal medicine Cistanche deserticola Y.C. Ma has been recorded and treatment for infertility and impotence since ancient times, which is widely distributed in northwest China, and is mainly composed of phenylethanol glycosides, iridoids, lignans, polysaccharides, alkaloids, etc.
