Summary: Due to the use of toxic, flammable, and unstable organic liquid electrolytes, commercial lithium-ion batteries fail to provide sufficient protection for the safety and long-term life of portable devices. A double cross-linking ionogel electrolyte (DC-Ionogel) was successfully created by sealing EMIm(TFSI) in a double cross-linked network using a thiolate click reaction and ion interaction. The interlaced ion cross-linking network and covalent cross-linking network significantly increased the flexibility, stability, flame retardancy, and thermal dimensional stability of the ionogel electrolyte. DC-Ionogel also exhibited superior electrochemical performance with higher room ionic conductivity (1.79 x 10- 3S cm-1) and a broader electrochemical window (5 V), making it highly suitable for flexible energy-storage devices.

Summary: In this study, an oligomer stamping technique for selective bonding of normally closed valves is optimized for PDMS devices on glass substrates. The process is quantitatively characterized using contact angle and blister bursting testing measurements, and recommendations are made for plasma treatment conditions, microstamping technique, and valve construction. The glass-PDMS devices demonstrate electrical isolation and sealing capability under a pulsed actuation scheme.

Summary: The study found that EDC pretreatment and aging significantly influenced bond strength and endogenous enzymatic activity. After 5 years of aging in artificial saliva, the EDC-treated groups exhibited higher bond strength and lower gelatinolytic activity, especially in the etch-and-rinse groups. Raman spectra showed less defined amide III peaks in control specimens at T5.

Summary: The cross-linking of silicone rubber can be achieved through reactions such as cross-linking with radicals and cross-linking by addition. Kinetic analysis with the Vyazovkin method can predict crosslinking rate and estimate experimental lag in moving die rheometry experiments. Conducting measurements for platinum catalyzed addition cure silicone rubber as soon as possible is important based on the results of the differential scanning calorimetry.
