The ability to control the particle size and morphology of nanoparticles is of crucial importance nowadays both from a fundamental and industrial point of view considering the tremendous amount of high-tech applications. Controlling the crystallographic structure and the arrangement of atoms along the surface of nanostructured material will determine most of its physical properties. In general, electronic structure ultimately determines the properties of matter. Soft X-ray spectroscopy has some basic features that are important to consider. X-ray is originating from an electronic transition between a localized core state and a valence state. As a core state is involved, elemental selectivity is obtained because the core levels of different elements are well separated in energy, meaning that the involvement of the inner level makes this probe localized to one specific atomic site around which the electronic structure is reflected as a partial density-ofstates contribution. The participation of valence electrons gives the method chemical state sensitivity and further, the dipole nature of the transitions gives particular symmetry information. The new generation synchrotron radiation sources producing intensive tunable monochromatized soft X-ray beams have opened up new possibilities for soft X-ray spectroscopy. The introduction of selectively excited soft X-ray emission has opened a new field of study by disclosing many new possibilities of soft X-ray resonant inelastic scattering. In this paper, some recent findings regarding soft Xray absorption and emission studies of various nanostructured systems are presented.

“…Foster Center for Irradiation of Material at the Alabama A&M University has accumulated significant experience in ion beam analysis techniques [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Innovative methods have been developed to detect impurities in light elements [8], notably in glassy polymeric carbon [9,10,11], a material whose development has been pioneered by researchers at AAMU, and in stainless steel alloys [12].…”

“…The detection methods include nuclear detection techniques, such as Rutherford Backscattering Spectrometry (RBS), Nuclear Reaction Analysis (NRA) and Elastic Recoil Detection (ERD), as well as other surface specific analytical techniques. Many of these techniques are unique in allowing analysis of elemental content and crystalline states as a function of depth near the surface of solids and are often the only techniques that allow accurate measurements of those properties of hard coatings as well as in producing modifications of the properties of optical [16][17][18][19]21,22], polymeric [16,20] and materials for sensors [24] and medical [23] applications by ion bombardment. Adjacent laboratories at AAMU contain all the equipment necessary to accomplish conventional engineering analysis, such as hardness, tensile strength and thermal properties and to accomplish infrared optical spectroscopy.…”
