Laser-induced backward transfer of gold nanodroplets

Laser-induced backward transfer of nanoimprinted polymer elements

Femtosecond laser-induced backward transfer of transparent photopolymers is demonstrated in the solid state, assisted by a digital micromirror spatial light modulator for producing shaped deposits. Through use of an absorbing silicon carrier substrate, we have been able to successfully transfer solid-phase material, with lateral dimensions as small as ~6 μm. In addition, a carrier of silicon in...

Numerical study of thermal dynamics of gold nanoparticles in laser-induced hyperthermia therapy

Damage of the normal tissue is a serious concenrn in cancer treatment. Hyperthermia by laserhas been considered as a safe cancer treatments methods with lower harmful effects on normaltissues. Using nanoparticles in cancer treatment has improved laser therapy, which is based ona selective cell targeting method to localize cell damages. Metallic nanoparticles such as gold,silver, and copper have...

Backward Pragmatic Transfer: The Case of Refusals in Persian

The purpose of this study was to examine Cook’s (2003) ‘multiple competence’ by investigating backward pragmatic transfer (from L2 [English] to L1 [Persian]) in refusals to invitations. It explored participants’ frequency and content of refusal strategies in L1 regarding the status (i.e., power and distance) of interlocutors and the proficiency level of EFL learners. The participants were Persi...

Laser-induced Forward Transfer of Ag Nanopaste

Over the past decade, there has been much development of non-lithographic methods(1-3) for printing metallic inks or other functional materials. Many of these processes such as inkjet(3) and laser-induced forward transfer (LIFT)(4) have become increasingly popular as interest in printable electronics and maskless patterning has grown. These additive manufacturing processes are inexpensive, envi...
