Induction heating has been employed to rapidly raise the temperature of ferrous specimens prior to testing at strain-rates > 10 s". The results show a general tendency for the ductility of a specially-processed pure iron to decrease with temperature over the range tested (20400 C). Based on the experimental data and the results of numerical simulations of the experiment, an empirical fracture m...

Ternary Pt-Au-M (M = 3d transition metal) nanoparticles show reduced OH adsorption energies and improved activity for the oxygen reduction reaction (ORR) compared to pure Pt nanoparticles, as obtained by density functional theory. The strain and ligand effects in nanoparticles are decoupled and correlated with the extended Pt(111) surface for benchmarking. The ternary metal in the core allows f...

The band width control through external stress has been demonstrated as a useful knob to modulate metal-insulator transition (MIT) in RNiO3 as a prototype correlated materials. In particular, lattice mismatch strain using different substrates have been widely utilized to investigate the effect of strain on transition temperature so far but the results were inconsistent in the previous literatur...

With the increasing focus on developing environmentally benign electronic packages, Pb-free alloys have received a great deal of attention. Mishandling of packages during manufacture, assembly or by the user may cause failure of the solder joint. A fundamental understanding of the behavior of Pb-free solders under mechanical shock conditions is lacking. Reliable experimental stress–strain data ...

INTRODUCTION Transcatheter aortic valve implantation is the option of choice for high surgical risk patients suffering from symptomatic aortic stenosis. We aimed to evaluate the influence of baseline global longitudinal strain on left ventricular mass regression after the procedure. METHODS We enrolled 23 patients with pure symptomatic severe aortic stenosis who underwent CoreValve prosthesis...

Sphingomonas sp. SRS2 was the first described pure strain that is capable of mineralizing the phenylurea herbicide isoproturon and some of its related compounds. This strain has been studied thoroughly and shows potential for bioremediation purposes. We present the draft genome sequence of this bacterium, which will aid future studies.
