We present a combined experimental and theoretical study of the mineral atacamite ${\mathrm{Cu}}_{2}\mathrm{Cl}(\mathrm{OH}{)}_{3}$. Density-functional theory yields Hamiltonian describing anisotropic sawtooth chains with weak 3D connections. Experimentally, we fully characterize antiferromagnetically ordered state. Magnetic order shows complex evolution magnetic field, while, starting at 31.5 T, observe plateaulike magnetization about ${M}_{\mathrm{sat}}/2$. Based on complementary...
Time-reversal symmetry and magnetoelastic correlations are probed by means of high-resolution volume dilatometry in ${\mathrm{URu}}_{2}{\mathrm{Si}}_{2}$ at cryogenic temperatures, magnetic fields sufficient to suppress the hidden order state ${H}_{\mathrm{HO}}(T=0.66\phantom{\rule{0.28em}{0ex}}\mathrm{K})\ensuremath{\simeq}35$ T. We report a significant expansion above ${H}_{\mathrm{HO}}(T)$, even ${T}_{\mathrm{HO}}$, possibly consequence field-induced $f$-electron localization. investigate...
51Cr and 60Co diffusion along grain boundary (GB) in polycrystalline Zr -Zr-20%Nb were measured by means of the radiotracer technique an overall temperature range [380-1000] K. The use Harrison´s C B kinetics resulted direct data GB diffusivity (Dgb) apparent (Pgb). analyzed temperatures involved those power reactors service. segregation factors s determined or evaluated limit very dilute solute concentration.
Chimaerods represent an enigmatic lineage of cartilaginous fishes and the least studied group within Chondrichthyans. They have a widespread global distribution with high degree endemism. In addition, this has been considered among threatened species Chondrichthyans, but also most data-deficient group, biological information lacking for species. This study represents first microanatomical, histological, ultrastructural description different stages folliculogenesis in Callorhinchus...
Zirconium and its alloys are widely used in nuclear industry (nuclear fuel cladding tubes, structural materials, etc.) for adequate properties under hostile conditions (corrosive environment, radiation damage, the core of reactors. In normal operating conditions, these materials present an important density grain interphase boundaries which act as quick paths movement matter can be contact with Fe based alloys. The fast diffusing elements (Fe, Co, Cr, Ni) short-circuit Zr [1] produce...
