Trace alcohol ether electrolytes with dual-site hydrogen bonds and modulated solvation structures for ultralong-life zinc-ion batteries.

Aqueous zinc-ion batteries (AZIBs) are highly regarded for their affordability, stability, safety, and eco-friendliness. Nevertheless, their practical application is hindered by severe side reactions and the formation of zinc (Zn) dendrites on the Zn metal anode surface. In this study, we employ tetrahydrofuran alcohol (THFA), an efficient and cost-effective alcohol ether electrolyte, to mitigate these issues and achieve ultralong-life AZIBs.

Regulating Functional Groups Enhances the Performance of Flexible Microporous MXene/Bacterial Cellulose Electrodes in Supercapacitors.

Ultrathin MXene-based films exhibit superior conductivity and high capacitance, showing promise as electrodes for flexible supercapacitors. This work describes a simple method to enhance the performance of MXene-based supercapacitors by expanding and stabilizing the interlayer space between MXene flakes while controlling the functional groups to improve the conductivity. TiCT MXene flakes are treated with bacterial cellulose (BC) and NaOH to form a composite MXene/BC (A-M/BC) electrode with a microporous interlayer and high surface area (62.

Citric Acid Confers Broad Antibiotic Tolerance through Alteration of Bacterial Metabolism and Oxidative Stress.

Antibiotic tolerance has become an increasingly serious crisis that has seriously threatened global public health. However, little is known about the exogenous factors that can trigger the development of antibiotic tolerance, both in vivo and in vitro. Herein, we found that the addition of citric acid, which is used in many fields, obviously weakened the bactericidal activity of antibiotics against various bacterial pathogens.

Rational design of flower-like MnO/TiCTcomposite electrode for high performance supercapacitors.

Combining the new two-dimensional conductive MXene with transition metal oxide to build composite structure is a promising path to improve the conductivity of metal oxide. However, a critical challenge still remains in how to achieve a good combination of MXene and metal oxide. Herein, we develop a facile hydrothermal route to synthesize the MnO/TiCTcomposite electrode for supercapacitors by synergistically coupling MnOnanowires with TiCTMXene nanoflakes.

3D Porous Compact 1D/2D Fe O /MXene Composite Aerogel Film Electrodes for All-Solid-State Supercapacitors.

2D MXene nanoflakes usually undergo serious restacking, that easily aggravates during the traditional vacuum-assisted filtration process; and thus, hinders the electrochemical performance of the corresponding film electrodes. Herein, 3D porous compact 1D/2D Fe O /MXene aerogel film electrode with an enhanced electrochemical performance is fabricated by freeze-drying assisted mechanical pressing. An introduction of 1D α-Fe O nanorods can not only alleviate the restacking of 2D MXene but also provide additional pseudocapacitance for the composite film system.

Renal papillary necrosis with urinary tract obstruction: A case report.

Background: Renal papillary necrosis (RPN) is a rare disease. It is difficult to distinguish RPN with urinary tract obstruction from upper urinary tract occupying lesions. We reported a case of RPN and made a definite diagnosis largely based upon its endoscopic characteristics.

Flexible MXene-Based Composite Films: Synthesis, Modification, and Applications as Electrodes of Supercapacitors.

MXenes, as a 2D planar structure nanomaterial, were first reported in 2011. Due to their large specific surface area, high ductility, high electrical conductivity, strong hydrophilic surface, and high mechanical flexibility, MXenes have been extensively explored in the development of various functional materials with desired performances. This review is aimed to summarize the current progress in synthesis, modification, and applications of MXene-based composite films as electrode materials of flexible energy storage devices.

Comparing two-dimensional ultrasonography with three-dimensional ultrasonography and MRI for the levator ani defects grading.

Levator ani defect (LAD) closely correlates with pelvic floor disorders (PFD). In general, LAD was graded by three-dimensional ultrasonography (3D-US) and MRI, which could be used hardly in some developing area. Our objective was to determine whether two-dimensional ultrasonography (2D-US), a method that is almost universally accessible, could be used to diagnose the LAD.

Comparison of translabial three-dimensional ultrasonography and magnetic resonance imaging for the grading of levator ani defects.

Levator ani defect (LAD) closely correlates with pelvic organ prolapse. This study aimed to compare the LAD grading between 3-dimensional ultrasonography (3D-US) and magnetic resonance imaging (MRI) and investigate the reasons for the difference using 3-dimensional pelvic models.Seventy-two Chinese women who were to undergo repair surgery were assessed by the prolapse staging, 3D-US and MRI.

Breakthrough Therapy, PRIME and Sakigake: A Comparison Between Neuroscience and Oncology in Obtaining Preferred Regulatory Status.

Background: Because of the increasing demand for drugs addressing life-threatening and rare diseases, regulatory agencies have developed a variety of accelerated regulatory pathways.

Translabial Ultrasound Combined With Magnetic Resonance Imaging Assessing the Distensibility of Levator Ani Muscle With Unilateral High-Grade Tears.
