it is oxygen insensitive. As a consequence, O2has a negligible influence on the catalytic process of FAD-GDH in a traditional BFC. Additionally, H2O2which inhibits enzymatic reaction at cathode, is not produced during the anodic enzymatic reaction by FAD-GDH according to the following equations3,...

2.3. Preparation Process and Data Recording Method First, the PI films were cleaned using an ultrasonic machine with distilled water and dried in a constant-temperature drying oven. Then, the laser beam was controlled using a digital oscillator, and the laser parameters were designed using the Mar...
Process parametersDirect Energy Deposition (DED) is a widely used method for rapid prototyping, particularly for making dense metal parts, despite its notable energy requirements. This paper presents a novel mathematical modeling method that links important process variables to energy consumption in ...
