Fluoropolymer-based organic memristor with multifunctionality for flexible neural network system

Dynamics of CF growth in the fluoropolymer medium To explore the CF growth in the fluoropolymer medium, we prepared the lateral-structured organic memristor, as shown in Fig. 1b. In the organic memristor, active and inert electrodes were made of gold and silver, respectively, and EGC-1700 was utilized as the hydrophobic fluoropolymer. We first measured the… Continue reading Fluoropolymer-based organic memristor with multifunctionality for flexible neural network system

Synthesis and characterization of ternary chitosan–TiO2–ZnO over graphene for photocatalytic degradation of tetracycline from pharmaceutical wastewater

Characterization of catalysts The XRD patterns of prepared TiO2, T1–Z1/CS, T2–Z1/CS, T1–Z1/CS1–Gr1, and T1–Z1/CS1–Gr2 are shown in Fig. 1a, b. According to these patterns, it could be found that the TiO2 has appeared mainly in the anatase crystalline phase. In other words, some phase transformations from anatase to rutile have been occurred due to the heat… Continue reading Synthesis and characterization of ternary chitosan–TiO2–ZnO over graphene for photocatalytic degradation of tetracycline from pharmaceutical wastewater

Selection of effective manufacturing conditions for directed energy deposition process using machine learning methods

Single-track experiments and evaluation The selection of process parameters is important in the DED process. The process parameters are the input values, and must be set prior to machine operation. The important parameters in the DED process are the laser power, scan speed, and powder feed rate. The accuracy and quality can be changed according… Continue reading Selection of effective manufacturing conditions for directed energy deposition process using machine learning methods
