Triboelectrification is reported as a surface phenomenon and is explained by the electron cloud overlap model explained in the Wang transition concept. Therefore. the performance enhancement of Triboelectric Nanogenerators (TENGs) need to be explored through strategies to engineer the surfaces for increased surface contact area and surface roughness. Surface patterning strategies hold... https://www.parisnaturalfoodes.shop/product-category/vitamin-c-serum/
