Because of growing demands for thermal expansion control in a local region, typically inner components electronic devices, there is currently great deal interest negative (NTE) fine particles. The spray-drying method without grinding produced micrometer-scale particles pyrovanadate Cu1.8Zn0.2V2O7 showing large coefficient linear αL ~ –14 ppm/K equivalent to that the bulk body. solid-solution sy...
In the framework of a model, in which a single leptonic photon γl has the same coupling to the doublets μνμ and τ̄ ν̄τ , there is no cosmological bound on the strength of this coupling. A few papers devoted to hypothetical leptonic photons have appeared recently [1, 2, 3, 4] (for the first discussion of leptonic photons see ref. [5] for that of baryonic photons – ref. [6]). In particular in ref. ...
