Effect of print orientation and bronze existence on tribological and mechanical properties of 3D-printed bronze/PLA composite

open access: yesThe International Journal of Advanced Manufacturing Technology, 2020
In this work, fused deposition modeling (FDM) technology is employed for manufacturing tribological and tensile testing specimens. The test pieces are fabricated in diverse directions to examine the influence of print orientation.

Superconducting Properties of the K$_{x}$WO$_{3}$ Tetragonal Tungsten Bronze and the Superconducting Phase Diagram of the Tungsten Bronze Family [PDF]

open access: yesPhysRevB, 89 104520 (2014), 2014
We report the superconducting properties of the K$_{x}$WO$_{3}$ tetragonal tungsten bronze. The highest superconducting transition temperature ($T_{c}=2.1$K) was obtained for K$_{0.38}$WO$_{3}$. $T_{c}$ decreases linearly with increasing K content. Using the measured values for the upper critical field $H_{c2}$, and the specific heat $C$, we estimate ...
