Sheelite-related strontium molybdates: synthesis and characterization

“…Synthesis of Sr [14]. One possible reason was that the dopants influence differently the composition and structure of strontium and calcium molybdates.…”

“…One possible reason was that the dopants influence differently the composition and structure of strontium and calcium molybdates. The simultaneous presence of Bi and V in Ca 1-x Bi x Mo 1-x V x O 4 leads to the expansion of the unit cell of a complex oxide due to the replacement of calcium with bismuth and compression of the unit cell due to the replacement of molybdenum with vanadium; as a result, the unit cell changes slightly [14] (ionic radii r Ca 2+ = 1.12 Å, r V 5+ = 0.54 Å, r Mo 6+ = 0.41 Å [17]). In contrast, in In the Table 1, the unit cell parameters of the single-phase samples are shown.…”

“…x O 4 , respectively [14]. The present research is devoted to the Bi-doped strontium molybdate SrMoO 4 .…”

“…I4 1 / a) and described its good catalytic properties [15]. Sr 1-1.5x Bi x MoO 4 family has not been described yet, while Bi-doped calcium molybdates have been intensively researched as microwave dielectric [16] or pigments [14]. The basic characteristic and structure types of SrMoO 4 are similar to those of CaMoO 4 , so the Bi-doped strontium molybdates should possess similarly promising properties.…”

A Pilot Test to Analyse the Differences of Pedestrian Thermal Comfort Between Locals and Internationals in Malacca Heritage Site

“…Interestingly, clay tiles naturally consist of transparent crystalline particles with directional anisotropic refractive indices. According to Levinson et al (2007) and Sameera et al (2017), bare red clay tile can achieve near-infrared radiation (NIR) for high solar reflectance and high thermal emission to remain cooler under the sun. PET values at sites V and VII were noticeably higher than at any of the other sites for the period of the measurement procedures.…”
