Porous self-protonating spiropyran-based NIPAAm gels with improved reswelling kinetics
(Springer, 2016-02)
[EN] This study focuses on improving the speed ofactuation of poly(N-isopropylacrylamide)-based photoresponsive gels containing copolymerised spiropyran as the photoswitch and acrylic acid as the proton source. The improvement ...
Hydrothermal Synthesis and Study of Inorganic-Organic Hybrid Vanadate of Nickel(II) Coordination Complex with Pyrazine, Ni3(C4H4N2)3(V8O23)
(Elsevier, 2011-02-25)
The three-dimensional hybrid compound Ni3(C4H4N2)3(V8O23) has been synthesized by mild hydrothermal methods under autogenous pressure at 170 ºC, together with another hybrid phase, Ni2(C4H4N2)(V4O12)(H2O)2. The isolation ...
A rational fraction polynomials model to study vertical dynamic wheel-rail interaction
(Elsevier, 2012-04)
This paper presents a model designed to study vertical interactions between wheel and rail when the wheel moves over a rail welding. The model focuses on the spatial domain, and is drawn up in a simple fashion from track ...
Dynamic optimization of track components to minimize rail corrugation
(Elsevier, 2009-01)
In this paper, the influence on corrugation of the most significant track parameters has been examined. After this parametric study, the optimization of the track parameters to minimize the undulatory wear growth has been ...
On the influence of conformity on wheel–rail rolling contact mechanics
(Elsevier, 2016-07)
The aim of this work is to assess the effects of conformity on local contact related quantities at the wheel–rail interface such as traction distributions, subsurface stresses and frictional work distributions.
For this ...
