Recently reported results on the behaviour of the tungsten under conditions expected in the Neutrino Factory target have strengthened the case for a solid target option for the Neutrino Factory. This paper gives a description of the measurements of the surface motion of tungsten wires, stressed by a pulsed current, using a Laser Doppler Vibrometer in order to measure tungsten properties at high...

In this work, a novel technique is presented for the graphene fabrication based on the pulsed laser ablation of graphite target inside the cryogenic liquid using the pulsed nanosecond Q-switched Nd:Y3Al5O12 (Nd:YAG) laser at 1064 nm. Single-stage fabrication process is taken into account as a remarkable advantage without need to high vacuum devices and additional chemical components. The synthe...

Cerium-doped Tb(3)Al(5)O(12) (TAG:Ce(3+)) colloidal nanocrystals were synthesized by pulsed laser ablation (PLA) in de-ionized water and lauryl dimethylaminoacetic acid betain (LDA) aqueous solution for luminescent bio-labeling application. The influence of LDA molecules on the crystallinity, crystal morphology, crystallite size, and luminescent properties of the prepared TAG:Ce(3+) colloidal n...

Pulsed laser strategies (i.e. pulsed ablation and fragmentation in liquid) have been reviewed with a focus on the synthesis processing of amorphous metal nanoparticles. The possible formation criteria mechanism discussed.

We report the detailed experimental study on the production of electron-spin-polarized Sr+ ions through one-photon resonant two-photon ionization via laser-excited 5s5p 3P1 (MJ = +1) of Sr atoms produced by laser-ablation. We have experimentally confirmed that the use of laser-ablation for the production of Sr atoms prior to photoionization does not affect the electron-spin polarization. We hav...

Graphene oxide was prepared using modified Hummers method. Stable ethylene-glycol nanofluids containing graphene oxide nanosheets were provided. Nd: YAG pulsed laser was applied to prepare reduced nanofluids. Experimental results revealed that thermal conductivity of the nanofluids is increased with increasing the concentration of graphene oxide (GO) in ethylene glycol. The enhancement ratio of...

Ultrashort pulsed laser ablation of dielectrics has been investigated using ex-situ morphological examinations in combination with in-situ time-of-flight mass spectrometry of the ablated species. Analysis of the energy spectrum of the ablation products provides a wealth of information on the processes occurring during femtosecond laser ablation of materials. The presentation will focus on the c...

The ability to suspend plasmonic metal nanoparticles in apolar environments is an important feat towards harnessing their optical properties for use amphiphilic biological environments. Pulsed laser Ablation Liquids (PLAL) a well-established method the production of gold (AuNPs) aqueous environments; however, ablation organic liquids synthesis hydrophobic AuNPs still has many unknowns, such as ...

Diamond coating of tungsten carbide-cobalt (WC-Co) cemented carbide tools using chemical vapour deposition (CVD) requires removal the cobalt (Co) binder phase from WC-Co surface in order to improve adhesion. Laser ablation is shown be a promising technique for selective Co, which based on difference melting and boiling temperatures between different phases. However, laser with conventional nano...
