Kinetics and reaction mechanism of biothiols involved in SNAr reactions: an experimental study
(Frontiers Media, 2022)
Few kinetic parameters, or reaction rates, are known up to date in detail about 1-chloro and 1-fluoro-2,4-dinitrobenzene (ClDNB and FDNB, respectively) with a series of biothiols in aqueous media. These biological nucleophiles ...
Determination of fracture toughness of propylene polymers at different operating temperatures
(Pergamon-elsevier Science Ltd, 2014-05-17)
The influence of the temperature on the fracture parameters of three types of polypropylenes under static loading conditions has been analyzed. Single-phase polypropylene homopolymer and random ethylene?propylene copolymer ...
Analog parameters of solid source Zn diffusion in X Ga1-XAs nTFETs down to 10 K
(2016-10-28)
The analog parameters of In0.53Ga0.47As and In0.7Ga0.3As nTFETs with solid state Zn diffused source are investigated from room temperature down to 10 K. The In0.7Ga0.3As devices are shown to yield a higher on-state current ...
Mechanical properties of BiP protein determined by nano-rheology
(Blackwell Publishing Ltd, 2018)
© 2018 The Protein Society Immunoglobulin Binding Protein (BiP) is a chaperone and molecular motor belonging to the Hsp70 family, involved in the regulation of important biological processes such as synthesis, folding and ...
Effective parameters for conductive contributions to radial heat transfer in fixed beds under stagnant conditions
(Inst Chemical Engineers, 2017-03)
New expressions to evaluate the thermal conduction parameters in fixed beds of monosized spheres are presented in this paper. The parameters are those introduced by the 2R2D model proposed by Asensio et al. (2014): the ...
Symmetrical Observability of Kinematic Parameters in Symmetrical Parallel Mechanisms
(Editora Edgard Blücher Ltda., 2014-05)
This article presents an application of symmetry group theory in kinematic identification of parallel mechanisms of nlegs legs -- Kinematic Identification implies the estimation of the actual geometrical parameters (as ...
