Regulation of the Escherichia coli L10 Operon
1986It is now clear that in Escherichia coli the synthesis of many of the components involved in transcription and translation are carefully regulated. For example, the expression of a number of these genes is under stringent control (Dennis and Nomura, 1974; Furano and Wittel, 1976), the mechanism by which bacteria, when starved for an amino acid, turn ...

Order Parameter in L10 FePt Nanocrystals
Transactions of the Indian Institute of Metals, 2014FePt nanocrystals with L10 chemical order have high magnetic anisotropy. FePt nanocrystals with fcc structure need to be heated to 600 °C to form the hard magnetic L10 phase. The order parameter (S) in nanocrystals changes during annealing. The order parameter in L10 FePt nanocrystals determines the relation between chemical ordering in this structure ...

Crystallographic aspects of L10 magnetic materials
Scripta Materialia, 2005In this paper we present an overview of various features of the structure of L10 magnetic phase. We discuss the various microstructural features which occur in these materials due to the changes in symmetry (translational and orientational domains) as well as the relationship between the crystal symmetry and features such as the thermodynamic order of ...

Journal of Applied Physics, 2006
L 1 0 - Fe Pt (001) and L10-FePt (110) dot arrays with well-defined geometry were fabricated through the use of electron beam lithography and Ar ion etching. The lateral size of dots was varied in the range from 0.2×0.2to5×5μm2. Coercivity (Hc) for the perpendicularly magnetized FePt (001) dots increases with decreasing the dot size. In the case of the

L10 versus Leq—A User's Perspective
1979The Federal Highway Administration (FHWA) regulation tor highway traffic noise analysis, FHPM 7-7-3, allows for the use of either L10 (sound level exceeded 10 percent of the time) or Leq (energy equivalent sound level). Therefore, state highway agencies have the responsibility to empirically determine the preferable descriptor (L10 or Leq) for typical ...

In situ L10 ordering of FePt nanoparticles
2008Assemblies of monodisperse FePt nanoparticles (NPs) are promising candidates for next generation data storage media with recording densities beyond 1 Tbit.inch due to their high uniaxial magnetocrystalline anisotropy, which can reach 107 J.m-3 along the [001] direction of the face-centered tetragonal (fct) L10 ordered phase.2 Triggered by the seminal ...
