Mortality and disability associated with TBM are high in China. Limb weakness, GCS scores, cranial-nerve palsy and hydrocephalus were independent predictors of poor outcomes, and AGR, NLR, D-dimer, and EEG abnormalities may be prognostic factors of TBM.

Developing a simple and direct approach for interfacing a sensor and a target analyte is of great interest for fields such as medical diagnosis, threat detection, food quality control, and environmental monitoring. Gloves provide a unique interface for sensing applications. Here, we show for the first time the development of wearable carbon nanotube (CNT)-based amperometric biosensors painted onto gloves as a new sensing platform, used here for the determination of lactate. Three sensor types were studied, configured as: two CNT electrodes; one CNT electrode, and an Ag/AgCl electrode, and two CNT electrodes and an Ag/AgCl electrode. The sensors are constructed by painting the electrodes using CNT or Ag/AgCl inks. By immobilizing lactate oxidase onto the CNT-based working electrodes, the sensors show sensitive detections of lactate. Comparison of sensor performance shows that a combination of CNT and Ag/AgCl is necessary for highly sensitive detection. We anticipate that these findings could open exciting avenues for fundamental studies of wearable bioelectronics, as well as practical applications in fields such as healthcare and defense.

With a rapid charge/discharge feature, vanadium redox flow batteries (VRBs) are green, large-scale energy storage devices useful for power smoothing in unstable renewable power generation facilities, such as those involving solar and wind energy. This study developed a VRB model to establish a relationship between electrolyte concentration, equilibrium potential, and state of charge (SOC), to simulate the dynamic responses in charge/discharge cycles of the electrolyte concentration, terminal voltage, and SOC, and to evaluate the internal loss and battery efficiency. The proposed model not only serves as the basis of a dynamic analysis tool for future studies for designing a large-scale VRB but also reveals the time-varying electrolyte status for a long-term VRB operation.
