Aaltonen, T.; Abazov, V. M.; Abbott, B.; Acharya, B. S.; Adams, M.; Adams, T.; Agnew, J. P.; Alexeev, G. D.; Alkhazov, G.; Alton, A.; Amerio, S.Made available in DSpace on 2022-04-28T19:07:28Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-01-24; The CDF and D0 experiments at the Fermilab Tevatron have measured the asymmetry between yields of forward- and backward-produced top and antitop quarks based on their rapidity difference and the asymmetry between their decay leptons. These measurements use the full data sets collected in proton-antiprot...

No. of bitstreams: 0 Previous issue date: 2010-02-12; Science and Technology Facilities Council; We combine searches by the CDF and D0 Collaborations for a Higgs boson decaying to W+W-. The data correspond to an integrated total luminosity of 4.8 (CDF) and 5.4 (D0) fb-1 of pp̄ collisions at √s=1.96TeV at the Fermilab Tevatron collider. No excess is observe...
Influence of laser surface nanotexturing on the friction behaviour of the silic...
Alves-Lopes, I.; Almeida, Amelia; Oliveira, Vítor; Vilar, R.The aim of the present work was to investigate the influence of textures consisting of Laser-Induced Periodic Surface Structures (LIPSS) on the friction coefficient of silicon under unlubricated conditions, using nanoscale friction tests. The tests were performed on <1 1 1> single crystal wafers of p-doped silicon. Surface texturing was performed by a direct writing technique, using 560 fs pulses of 1030 nm wav...

Phase-change magnetic memory: Rewritable ferromagnetism by laser quenching of c...
Polushkin, Nikolay I.; Oliveira, Vitor; Vilar, R.; He, M.; Shugaev, Maxim; Zhigilei, LeonidHigh-intensity laser irradiation can effectively couple to practically all kinds of materials, causing modification of their physical properties due to laser-induced phase transformations. This gives rise to a broad field of laser micro- and nanofabrication with its various technological applications. We demonstrate that, in a 40-nm-thick film of Fe60Al40 alloy, a short laser pulse is capable of (re)writing the...
Influence of femtosecond laser treated surfaces on the mode I fracture toughnes...
Ferreira Moreira, Raul Domingos; Oliveira, Vitor; Silva, Filipe Gonçalo Andrade Da; Vilar, R.; Moura, MarceloThe influence of laser surface treatments on mode I fracture toughness of carbon fibre reinforced composites bonded joints is addressed in this work. Five different surface treatments considering several combinations of laser fluence and scanning speeds were applied prior to bonding of the adherents, aiming to increase the adhesion and, consequently, the fracture resistance of the bonded joint. Mode I fracture ...

Ferreira Moreira, Raul Domingos; Oliveira, Vitor; Silva, Filipe Gonçalo Andrade Da; Vilar, R.; Moura, MarceloMode II fracture toughness of carbon–epoxy bonded joints considering laser treated surfaces was evaluated using the End-Notched Flexure (ENF) test. Four different surface preparations were performed using distinct processing conditions before bonding the specimen arms. The Resistance-curves of the fracture tests were obtained considering an equivalent crack length based procedure. The influence of the different...
