... subjected to heat treatment at different temperatures (400°C–450°C–500°C) and the ellipsometric, structural, morphological, optical, and electrical properties of the films were investigated. The optical parameters of the V₂O₅ films were calculated by different theoretical methods...

... phase and some pearlite structure (21% in the surface), and the rest of the surface was covered by very fine voids in various sizes from 2 to 40 μm. Based on the morphology and sizes of the pores, observable in Figure 2(b) , the voids were related to the casting process. Moreover, the voids were...

... hexagonal nanocrystals were synthesized at a low temperature (70°C). The role of hexamethylenetetramine (HMTA; C₆H₁₂N₄) in engineering pure and doped zinc oxide morphology was examined. The results indicated that the hexagonal plates are transformed into a hexagonal...

... tests were performed on the composite specimens. In addition, morphological investigations were performed on the fractured surfaces of the specimens by using scanning electron microscopy. It is concluded that composites with a small-sized chestnut wood flour as the filler have superior properties...

.... Modulus of elasticity, tensile strength, elongation at break and Izod impact strength values decreased with increasing hornbeam sawdust size. The morphology of composite samples was examined by scanning electron microscopy. The results show that the hornbeam sawdust can be used as a filler in polymer...
