Measurement of wood surface roughness in Dinizia excelsa Ducke using an atomic force microscope

Measurement techniques of nanoscale parameters have been vastly explored nowadays. In systems such as wood that possess anisotropic surfaces, these provide reliable data on the surface morphology and related parameters. The atomic force microscope (AFM) optical were used to investigate roughness Dinizia excelsa. Cuts made in different directions generating three distinct surfaces: radial, tangential transverse. samples went through a sanding process reveal original steering. Both show texture is according analysed surface. lowest was observed transverse plane while highest occurred radial. comparison evaluation by two allowed us see AFM technique revealed most sensitive images smaller scales. These results confirmed can satisfactory for excelsa depending cut direction. This type analysis be useful laboratory species identification processes deforestation inspection Amazon
