Superconductivity in rubidium - substituted
We report on the synthesis and the physical properties of Ba1−xRbxTi2Sb2O (x ≤ 0.4) by x-ray diffraction, superconducting quantum interference device magnetometry, resistivity, and specificheat measurements. Upon hole doping by substituting Ba with Rb, we find superconductivity with a maximum Tc=5.4 K. Simultaneously, the charge-density-wave transition temperature is strongly reduced from TCDW�...

متن کاملPotassium and Rubidium Uptake in Freshwater Bivalves
Potassium transport characteristics were investigated in three species of freshwater bivalves: a corbiculid, Corbiculafluminea, and two unionids, Carunculina texasensis and Ligumia subrostrata. Using K, all three were found to take up potassium from dilute artificial pondwater ([K] about O.OSmmolP). The influx (7i) was 0.72/iequivg"drytissueh^ in the corbiculid, significantly higher than the va...
متن کاملHigh-temperature Superconductivity in compressed Solid Silane
Crystal structures of silane have been extensively investigated using ab initio evolutionary simulation methods at high pressures. Two metallic structures with P2₁/c and C2/m symmetries are found stable above 383 GPa. The superconductivities of metallic phases are fully explored under BCS theory, including the reported C2/c one. Perturbative linear-response calculations for C2/m silane at 610 G...

above. For example, does each carbon atom of the ring in phenol lack one electron of filling its eight "possible electron positions" or do three of the carbon atoms lack two electrons each while the remaining three carbon atoms have all their "possible electron positions" filled, or is there some other combination? In conclusion, the main purpose of presenting this detailed scale model of the b...
