Use of carbon nanotubes functionalized via plasma for the preparation of PA6-based nanohybrids
2011
MULTIFUNCTIONAL FIBERS BASED ON POLYAMIDE 6 AND PLASMA FUNCTIONALIZED CARBON NANOTUBES MoDeSt 2012 Conference, Praga, 2-6 Settembre 2012.
2012
Commercial (CNT 1) and ad hoc synthesized carbon nanotubes (CNT 2) were plasma treated under oxygen atmosphere and then added to polyamide 6 (PA 6) in order to prepare multifunctional fibres by melt spinning. For comparison, pristine nanofillers were used too. The effect of functionalization and of filler characteristics on the morphological, rheological, mechanical and electrical properties of the fibers was studied by TEM and SEM, rheological measurements, tensile tests and electrical conductivity tests. The amalysis of Raman spectra put into evidence that the intensity of D-band (correlated with the degree of functionalization by the different vibration mode of carbon atoms in the presen…

Measurement of the lifetime of tau-lepton
1996
The tau lepton lifetime is measured with the L3 detector at LEP using the complete data taken at centre-of-mass energies around the Z pole resulting in tau_tau = 293.2 +/- 2.0 (stat) +/- 1.5 (syst) fs. The comparison of this result with the muon lifetime supports lepton universality of the weak charged current at the level of six per mille. Assuming lepton universality, the value of the strong coupling constant, alpha_s is found to be alpha_s(m_tau^2) = 0.319 +/- 0.015(exp.) +/- 0.014 (theory). The tau lepton lifetime is measured with the L3 detector at LEP using the complete data taken at centre-of-mass energies around the Z pole resulting in τ τ =293.2 ± 2.0 (stat) ± 1.5 (syst) fs .

Cobalt Electrolyte/Dye Interactions in Dye-Sensitized Solar Cells: A Combined Computational and Experimental Study
2012
We report a combined experimental and computational investigation to understand the nature of the interactions between cobalt redox mediators and TiO2 surfaces sensitized by :ruthenium and organic dyes, and their impact on. the performance of the corresponding dye-sensitized solar cells (DSSCs). We : focus: on different ruthenium dyes and fully organic dyes, to understand the dramatic loss of efficiency observed for the prototype Ru(II) N719 dye in conjunction with :Cobalt: electrolytes. Both N719- and Z907-based DSSCs showed an increased lifetime in iodine-based electrolyte compared to the cobalt-based redox-shuttle; While the organic D21L6 and D25L6 cycles endowed.With long alkoxy chains,…

15-years mortality in asthma-COPD overlap syndrome (ACOS) elderly population
2015
Background: The coexistence of asthma and chronic obstructive pulmonary disease (Asthma-COPD Overlap Syndrome: ACOS) is increasingly recognized. Data about the prevalence of ACOS in the elderly and its prognostic implications are unknown. Aim: To evaluate the long-term mortality of ACOS in an elderly population. Methods: 1970 subjects, aged >65 yrs, were enrolled in the population-based SA.R.A. Study. ACOS was defined as: not fully reversible airflow limitation + a) history of asthma or b) very positive bronchodilator test (increase in FEV1 ≥15% and ≥400 ml) + atopy + weezing. The prevalence of ACOS and 15-years mortality rates were assessed in 1063 subjects with complete clinical, lung fun…
Once-daily QVA149 improves dyspnoea and health status compared with tiotropium plus formoterol in patients without ICS use: A post-hoc analysis of th…
2015
Rationale: The QUANTIFY study compared the approved dual bronchodilator QVA149 with the free-dose combination of tiotropium plus formoterol (TIO+FOR) regarding lung function, dyspnoea and health status in patients with moderate-to-severe COPD. This post-hoc analysis reported on the subgroup of pts without ICS background therapy. Methods: This blinded, triple-dummy 26-week study randomised patients to QVA149 110/50 µg OD or TIO 18 µg OD plus FOR 12 µg b.i.d. (1:1). ICS was allowed as background therapy. Endpoints included lung function (trough FEV1), dyspnoea (TDI) and health status (COPD Assessment Test, CAT). Results: Of the 934 pts randomised (QVA149 [N=476] or TIO+FOR [N=458]); 87.9% com…

Wearable electromyography recordings during daily life activities in children with cerebral palsy.
2020
To test whether wearable textile electromyography (EMG) recording systems may detect differences in muscle activity levels during daily activities between children with cerebral palsy (CP) and age-matched typically developing children.Wearable textile EMG recording systems were used to obtain leg muscle activity in 10 children with spastic CP (four females, six males; mean age 9y 6mo, standard deviation [SD] 2y 4mo, range: 6-13y; Gross Motor Function Classification System [GMFCS] level I and II) and 11 typically developing children (four females, seven males; mean age 9y 9mo, SD 1y 11mo, 7-12y) at rest and while performing seven daily activities.Children with CP showed significantly lower a…
