Laser desorption mass spectrometry was used in the production and analysis of gas phase metal sulfur clusters. Clusters of gas phase aluminum, gallium, and indium sulfur were produced and analyzed using a time-of-flight mass spectrometer. Also, carbon nano-onions produced by an arc between graphite electrodes in water and the annealing of nanodiamonds were analyzed. The sulfur experiments were ...

Development of nano and biotechnologies encouraged us to develop a concept of automated building, which will significantly reduce the many negative impacts of traditional construction on the environment. The paper describes the concept of Nanoto meter-scale building, a new way of building, which unfolds from the nano into the meter range. The concept is based on bionanorobots, producing buildin...

Carbon nanotubes (CNTs) have attracted attention for their remarkable electrical properties and have being explored as one of the best building blocks in nano-electronics. A key challenge to realize such potential is the control of the nanotube growth directions. Even though both vertical growth and controlled horizontal growth of carbon nanotubes have been realized before, the growth of comple...

In this research, Carbon-doped TiO2 nano-photocatalyst is synthesized via sol-gel technique and photo-catalytic degradation of phenol has been studied under ultraviolet and visible light irradiation in a fluidized bed reactor. Various techniques are used to characterize TiO2 nano-photocatalyst such as X-Ray Diffraction, Fourier transform infrared spectroscopy,  Energy Disp...

X-Ray Raman Spectroscopy (XRS) is used to study the electronic properties of bulk lithium borohydride (LiBH(4)) and LiBH(4) in porous carbon nano-composites (LiBH(4)/C) during dehydrogenation. The lithium (Li), boron (B) and carbon (C) K-edges are studied and compared with calculations of the starting material and intermediate compounds. Comparison of the B and C K-edge XRS spectra of the as-pr...
