Titanium dioxide (TiO) nanotubes have been explored for applications in various fields, and their performance is influenced by their length. To investigate the factors affecting the length of anodic TiO nanotubes, samples were fabricated under different applied voltages and in electrolytes with varying poly(ethylene glycol) (PEG) concentrations. The study found that the steady-state current density in the current density-time curve exhibits a strong linear relationship with nanotube length.

Background: Female reproductive diseases-including endometriosis (EMs), uterine fibroids (UFs), polycystic ovary syndrome (PCOS), gestational diabetes mellitus (GDM), eclampsia, ectopic pregnancy (EP), infertility, miscarriage, and ovarian aging-pose significant global health challenges. Metabolic syndrome (MetS) is characterized by a series of metabolic irregularities and has been linked to distinct plasma metabolomic profiles. Investigating the etiological connections among MetS, plasma metabolites, and female reproductive diseases is essential for devising effective prevention and treatment strategies.

  • This study compares the microstructure and dielectric properties of anodic aluminum oxide films created via micro-arc oxidation (MAO) and conventional anodic oxidation (CAO).
  • MAO produces a film with more and larger pores due to the release of oxygen bubbles during plasma sparking, influencing its structure.
  • Post-MAO treatment, the dielectric properties show a significant decrease in leakage current, with reductions ranging from 56% to 74% across different tested electrolytes.

In this study, a hydrothermal process was utilized to grow mixed-valence CuFeO/Cu nanosheets on carbon fiber paper, forming a three-dimensional hierarchical electrode (CuFeO/Cu@CFP). The ordered array structure, coupled with the porous bowl-like structure, enhances the exposure of more electrode active sites and facilitates analyte penetration, thus enhancing the electrode sensing performance. As a binder-free sensor, the CuFeO/Cu@CFP sensor exhibited remarkable sensitivity in detecting Malachite Green (MG), Sunset Yellow (SY) and Tartrazine (TA) over wide concentration ranges: 0.

With the increasing application of lithium-ion batteries, the demand for high energy density, high-rate performance and high stability lithium-ion batteries is becoming more and more urgent. TiCO MXene, as a two-dimensional material with multilayer atomic structure and multiple active sites, has great advantages in lithium-ion battery electrode materials. However, the original TiCO MXene has been unable to meet the requirements of lithium-ion batteries due to its semiconductor properties.

Dynamic polyimines are a class of fascinating dynamic polymers with recyclability and reparability owing to their reversible Schiff-base reactions. However, balancing the dynamic properties and mechanical strength of dynamic polyimines presents a major challenge due to the dissociative and associative nature of the imine bonds. Herein, we introduced bulky fluorene groups and polyether amine into the skeleton of polyimine networks to achieve a tradeoff in comprehensive properties.

Article Synopsis
  • Flower bud formation is crucial for fruit yield and quality, influenced by a balance between the proteins FT (FLOWERING LOCUS T) and TFL1 (TERMINAL FLOWER1).
  • In apples, the protein MdFT1 promotes flowering while MdTFL1 acts to repress it, with both being regulated by the transcription factor MdbHLH48.
  • MdbHLH48 enhances MdFT1 and inhibits MdTFL1, interacting with MdWRKY6 to ultimately control flower bud formation in apples.
