Quantum size effects of Pb overlayers at high coverages.
(Elsevier, 2007-07-18)
We have studied Pb thin films as a function of the thickness up to 60 monolayers (MLs) using ab initio first principles and model calculations. Magic heights corresponding to a modulated oscillatory pattern of the energy ...
Neutrophils of Centenarians Show Function Levels Similar to Those of Young Adults
(Wiley, 2008)
OBJECTIVES: To analyze several functions and antioxidant parameters of peripheral blood neutrophils from healthy centenarians (men and women) and compare them with those of healthy young (aged 25–35) and middle-aged (aged ...

Raman spectroscopy assisted with XRF and chemical simulation to assess the synergic impacts of guardrails and traffic pollutants on urban soils
(Wiley, 2012-11-01)
Urban soils are potential reservoirs of toxic metals as a consequence of traffic emissions. Sources like brake linings, tyres, road pavement, exhaust fumes, guardrail, traffic signals and other galvanised steel structures ...
Electric Arc in Low-Voltage Circuit Breakers: Experiments and Simulation
(IEEE, 2017-01)
The aim of this paper is to present a further
approach for analyzing the air electric arc in low-voltage
circuit breakers (LVCBs). In order to achieve that, a new
simulation model and experimental tests have been carried ...
Electrochemical behavior of metal-supported SOFCs under high fuel utilization and their durability
(ASME, 2012)
The aim of this project was to study whether the oxidation resistance of cells is affected while working under high fuel utilization. A previous study measured the weak oxidation resistance for very porous samples (measured ...
Morphological study and photo-addressing in poly(styrene-b-butadiene-b-styrene) block copolymers with azobenzene groups and polystyrene matrix: influence of chemical bonding
(2011-01-25)
The main goal of this work was the synthesis of new azo-functionalized block copolymers
(BCP) from epoxidized poly(styrene-b-butadiene-b-styrene) modified with azobenzene
groups by one-step facile reaction between the ...
