Reddish Au condensates, predominant atom clusters and minor amount of multiply twinned particles and fcc nanoparticles with internal compressive stress, were produced by pulsed laser ablation on gold target in de-ionized water under a very high power density. Such condensates were self-assembled as lamellae and then nano- to micro-diameter tubes with multiple walls when aged at room temperature...

The 1-, 2-, and 3-dimensional structures obtained from conjugated rings of carbon atoms are reviewed. They include finite small and large molecules (benzenoids, collarenes, beltenes, cyclacenes, cyclophenacenes, Möbius analogs, nanotori) and infinite macromolecules, nets and tilings (graphene, defected graphene, fractal benzenoids, nano-tubes, nano-cones, etc.). A few challenges for future expe...

To understand the pathogenic processes for infectious bacteria, appropriate research tools are required for replicating and characterizing infections. Fluorescence and bioluminescence imaging have primarily been used to image infections in animal models, but optical scattering in tissue significantly limits imaging depth and resolution. Photoacoustic imaging, which has improved depth-to-resolut...

This paper shows the research work on heat exchanger using nano fluid. In this paper we are using compact heat exchanger as heat transferring device while Al2O3 as a nano fluid. The effect of the nano fluids on compact heat exchanger is analyzed by using ε –NTU rating numerical method on turbo-charged diesel engine of type TBD 232V-12 cross flow compact heat exchanger radiator with unmixed flui...

I magine a three-dimensional city that is twelve times higher that the Great Pyramid of Giza in Egypt. It is the largest structure on the world and it floats over Tokyo Bay while being build largely by robots. It ...

the free vibration of the lattice cylindrical composite shell reinforced with carbon nano-tubes (cnts) was studied in this study. the theoretical formulations are based on the first-order shear deformation theory (fsdt) and then by enforcing the galerkin method, natural frequencies are obtained. in order to estimate the material properties of the reinforced polymer with nano-tubes, the modified...

nano fillers are part of new studies to enhance various properties of fluids and solids. for example, adding nanoparticles as an enforcement in nanocomposites or as an additive to improve thermal or electrical properties in nano-fluids are of extreme importance in science and industry. there are numerous methods to uniformly disperse nanoparticles in fluid and solid phase. one of the well-used ...
