Opis:
The present studies discuss the 3D-AFM nano-structural features of gramicidine – A trying to link between its nano-structural properties and its applications. The branching of polypeptide linkage of gramicidine needs special stereo – orientation to be applied as therapeutic antibacterial cream or ointment. The present 3D-AFM- investigations introduce important conclusive remarks enhance scientific community to understand why gramicidin family as antibiotic cream or ointment are structurally suitable with special surface topography enhance it to be applied as cream or ointment. Poly-peptide linkage chains have high flexibility factor with maximum degree of freedom to be bend or rotates.

Opis:
The synthesized Ni-alloy was prepared via conventional casting technique under vacuum and highly superheated treatment route. The casting parameters such as solidification cooling rate (SCR) was monitoring by both of AFM and SEM .Micro-structural investigations within different spots in the same sample indicated that γ matrix is the domain phase besides minor phases as MC carbides, σ phase and η phase which was observed to solidify in two forms as plate-like and blocky shape. The volume fraction (Vf) of σ and η phases was increased as the solidification cooling rate decreases. 3D-microstructural imaging map of the Ni-based super-alloy was constructed depending upon AFM-data evaluating that the morphology of the alloy-surface is a function of casting parameters .Furthermore raman spectra of highly superheated casted Ni-based super-alloy was performed to confirm existence of different phases recorded via SEM and EDX-elemental analysis with their corresponding different vibrational modes such as Ni-O vibrating modes in the region 360-510 cm-1 and Mo-O vibrating mode which lies at 1005 cm-1.

Opis:
The present research work involves the study of the 3-D surface microtexture of sputtered indium tin oxide (ITO) prepared on glass substrates by DC magnetron at room temperature. The samples were annealed at 450°C in air and were distributed into five groups, dependent on ambient combinations applied, as follows: I group, using argon (Ar); II group, using argon with oxygen (Ar+O2); III group, using argon with oxygen and nitrogen (Ar+O2+N2); IV group, using argon with oxygen and hydrogen (Ar+O2+H2); and V group, using argon with oxygen, nitrogen, and hydrogen (Ar+O2+N2+H2). The characterization of the ITO thin film surface microtexture was carried out by atomic force microscopy (AFM). The AFM images were stereometrically quantitatively analyzed to obtain statistical parameters, by ISO 25178-2: 2012 and ASME B46.1-2009. The results have shown that the 3-D surface microtexture parameters change in accordance with different fabrication ambient combinations.
