Glycerol is a byproduct of biodiesel production and, as such, it limited economic value. By means electrooxidation, glycerol can be used feedstock for scalable hydrogen production, in addition to conversion value-added products. The development novel and efficient catalytic electrode materials the anodic side reaction key towards hydrogen-based energy economy. In present study, computational sc...

The solid state reactions and structural evolution in nanocrystalline FePt powders during mechanical ball milling at 77 K and subsequent annealing have been investigated. Above 310 °C the formation of L10 FePt is observed. As the milling time increases, the enthalpy evolved during the transformations is reduced, whereas the corresponding activation energy increases. For accelerating the orderin...

In situ X-ray diffraction measurements reveal that the transformation of a AuCu nanoalloy from a face-centered-cubic to an L10 structure is accelerated under a hydrogen atmosphere. The structural transformation rate for the AuCu nanoalloy under hydrogen above 433 K was found to be 100 times faster than that in a vacuum, which is the first quantitative observation of hydrogen-induced ordering of...

Level fluctuating vibration has been evaluated by the cumulative index L10, but some investigators suggest that the L10 cannot represent an adverse comment on vibration. In order to clarify the compliant, various factors involving vibration need to be analysed together by statistical methods, for instance factor analysis or quantum theory. The authors investigated the relationship between an ev...

We cloned the genes encoding the ribosomal proteins Ph (Pyrococcus horikoshii)-P0, Ph-L12 and Ph-L11, which constitute the GTPase-associated centre of the archaebacterium Pyrococcus horikoshii. These proteins are homologues of the eukaryotic P0, P1/P2 and eL12 proteins, and correspond to Escherichia coli L10, L7/L12 and L11 proteins respectively. The proteins and the truncation mutants of Ph-P0...

The onset of chemical order L10 phase and perpendicular magnetic anisotropy in FePd 001 thin films sputtered on MgO 001 at temperatures from room temperature to 700 °C and thickness between 1.4 and 22 nm are investigated. It is found that the formation of the FePd ordered phase exhibiting high perpendicular magnetic anisotropy L10 phase with the c axis in the growth direction is affected by a t...

We present a study of the magnetic properties of arrays of nanostructures produced in a focussed ion beam–scanning electron microscope dual beam system. The single magnetic units have been isolated either by direct removal of parts of the metallic film or by local modification of the film magnetic properties. The final quality of the shape and the residual damage strictly depend on beam paramet...

Utilizing first-principles atomistic simulations we present a twin nucleation model based on the Peierls–Nabarro formulation. We investigated twinning in several important shape memory alloys, starting with Ni2FeGa (14M modulated monoclinic and L10 crystals) to illustrate the methodology, and predicted the twin stress in Ni2MnGa, NiTi, Co2NiGa, and Co2NiAl martensites, all of which were in exce...

In this work, we studied the effects of Sn addition on the ordering temperature of FePt thin film. The coercivity of FePtSn film was about 1000 Oe greater than the coercivity of FePt film for an annealing temperature of 600C. Therefore, Sn addition was effective in promoting the L10 ordering and in reducing the ordering temperature of the FePt film. From our X-ray diffraction results, we found ...
