In this study, triboelectric nanogenerators are fabricated using a variety of polymers, including PET, PMMA, and OHP sheets. Packaging aluminum foil functions as conducting electrode, while the PET, OHP, and PMMA act as triboelectric layers in the design. A flexible TENG with a 5 x 5 cm2 surface area produced …

This study examines supercapacitors using machine learning. Each model is tested using Random Forest, Support Vector Machine, Regression, and ANN. This article examines data selection and collection procedures to assure accuracy. It also shows how doping materials, surface area, and hole size affect supercapacitor efficiency. Case examples show how machine …

The use of Artificial Intelligence (AI) algorithms for analyzing practical data has increased with the advent of AI models. Combining physics and engineering has garnered a lot of interest so much, so that the triboelectric Nano-generators (TENG) industry may also use AI technologies. In this work, the classifiers suitable for …

Herein, we report the effect of ZnO thin film morphology on triboelectric nanogenerator (TENG) performance. The ZnO nanostructures were synthesized by a hot-plate method, which is an easy, inexpensive, low-temperature, and fast- process. We used ZnO film and PET as frictional layers to fabricate the TENG device. ZnO films that …

Silver surface is prone for tarnish when exposed to sulfide and sulfate environments. Present work reports protection of silver surfaces with sol-gel derived mixed oxides of titanium-silicon (TiO2-SiO2) thin films prepared at room temperature (300K) by dip coating technique without any post annealing. 0.1M and 0.3M titania and silica individual …
