Abstract A new mineral species, mikenewite (IMA2022-102), ideally Mn 2+ (S 4+ O 3 )⋅3H 2 O, has been discovered from the San Judas Chimney, Ojuela mine, Mapimí, Durango, Mexico. It occurs as spheres of platy crystals. Associated minerals include goethite, cryptomelane, adamite and lotharmeyerite. Mikenewite is yellowish in transmitted light, transparent with a white streak vitreous lustre. brit...

Based upon comprehensive theoretical investigations and known experimental observations, we predict the existence of the double-chain planar D(2h) B(4)H(2)(1), C(2h) B(8)H(2)(3), and C(2h) B(12)H(2)(5) which appear to be the lowest-lying isomers of the systems at the density functional theory level. These conjugated aromatic borenes turn out to be the boron hydride analogues of the conjugated e...

We present a feasible scheme to produce a polarization-entangled photon states 1 √ 2 (|H > |V > +|V > |H >) in a controllable way. This scheme requires single-photon sources, linear optical elements and photon detectors. It generates the entanglement of spatially separated photons. The interaction takes place in the photon detectors. We also show that the same idea can be used to produce the en...

The dynamic spheroidization mechanism and its orientation dependence in Ti-6Al-2Mo-2V-1Fe alloys during subtransus hot deformation were studied this work. For purpose, compression tests carried out at temperatures of 780–880 °C, with strain rates 0.001–0.1 s−1. Based on SEM, EBSD TEM characterization, the results showed that aspect ratio α phase decreased increasing decreasing rates. At 880 °C/...
