High-Power-Density Rechargeable Hybrid Alkali/Acid Zn-Air Battery Performance Through Value-Added Conversion Charging.

Rechargeable Zn-air batteries (ZABs) are considered highly competitive technologies for meeting the energy demands of the next generation, whether for energy storage or portable power. However, their practical application is hindered by critical challenges such as low voltage, CO poisoning at the cathode, low power density, and poor charging efficiency Herein, a rechargeable hybrid alkali/acid Zn-air battery (h-RZAB) that effectively separates the discharge process in an acidic environment from the charging process in an alkaline environment, utilizing oxygen reduction reaction (ORR) and glycerol oxidation reaction (GOR) respectively is reported. Compared to previously reported ZABs, this proof-of-concept device demonstrates impressive performance, exhibiting a high power density of 562.

Development of high-efficiency alkaline OER electrodes for hybrid acid-alkali electrolytic H generation.

The development of high-efficiency oxygen evolution reaction (OER) electrocatalysts is of great importance for electrolytic H generation. In this work, we report in-situ growth of MnCoO nanoneedles and NiFeRu layered double hydroxide (LDH) nanosheets on nickel foam (NF) (MnCoO@NiFeRu-LDH/NF) that can function a highly efficient electrode toward electrocatalysis of OER. Such electrode demands an overpotential of as low as 205 mV to reach 10 mA cm in alkaline electrolyte and can run stably over 120-hours continuous operation.

CircHIPK3 alleviates inflammatory response and neuronal apoptosis via regulating miR-382-5p/DUSP1 axis in spinal cord injury.

Background: Spinal cord injury (SCI) is one of the serious neurological diseases with high morbidity which may be treated with hematopoietic stem cell (HSC) transplants. Circular RNAs (circRNAs) play vital roles in SCI. The study aimed to reveal the function and mechanism of circRNA homeodomain interacting protein kinase 3 (HIPK3) in SCI.

Lentiviral delivery of biglycan promotes proliferation and increases osteogenic potential of bone marrow-derived mesenchymal stem cells in vitro.

Mesenchymal stem cells (MSCs) are multipotent progenitor nonhematopoietic cells that have emerged as an attractive cell source for tissue engineering. Biglycan (BGN), an extracellular matrix component, has been reported to play a crucial role in bone formation. However, the role of BGN in MSCs remains unknown.

The culture of temporary tumor-like bone marrow mesenchymal stem cells (TT-BMSC) and the detection of cell biology property.

Background: Bone marrow mesenchymal stem cells (BMSC) are common seed cells for transplantation. However, there are some limitations in their use that have not yet been resolved. Our research modified tumor-related genes temporarily on BMSC which simulated tumorigenesis temporarily in vitro.
