“…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.…”

“…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.…”

Sheelite-related strontium molybdates: synthesis and characterizationThe present research is devoted to the cationic-deficient SrMoO 4 -based sheelite-related complex oxides. The doping with bismuth to A sublattice and codoping with bismuth and vanadium (to A and B sublattices, respectively) were discussed. The X-Ray powder diffraction and infrared spectroscopy were used to investigate structural characteristics of the complex oxides. In Sr 1-1.5x Bi x MoO 4 , a superstructural ordering was observed. Conductivity and dielectric loss of ceramic samples are measured using alternating current.

“…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.…”

The present study aims to establish a correlation between the physiological equivalent temperature (PET) and subjective thermal sensation in the Tropics, assessing their impact on local as well as international pedestrians. The pilot test was conducted in six scenarios in the Malacca region of Malaysia. The RayMan model calculated the PET, which is further used to synthetically evaluate the thermal environment for six scenarios, each with a different river width and pavement material. The independent t-test and regression analysis determined the correlation between human thermal comfort acceptability and the thermal environment indices of outdoor spaces. Most of the outdoor thermal comfort assessments have been carried out focusing on local urban residents, while the same assessments on tourists are limited. This research provides necessary insight into the perception of outdoor microclimatic conditions in the Malacca heritage area and also identifies the perception on a few important psychological factors of these two demographic groups. An awareness of such issues would be fruitful for architects, planners and urban designers engaged in the process of designing and planning tourist destinations.

In this study, we provided a designed TiO 2 coating and hydrothermal treatment to synthesize nano-sized TiO 2 /SiO 2 cenospheres (TSCSs) with a rough surface for the application in the solar thermal reflective coating. Various functions of the TSCSs are present, the chemical composition causing significant UVA absorption, hollow interiors have high reflectance of the visible-IR radiation, and strong scattering of incident light. In addition, the low thermal conductivity of TiO 2 , SiO 2 , and the hollow interiors makes the coatings of TSCSs achieve a good thermal insulation. The average infrared reflectance of this coating is 89.61%, and the UVA transmission is only about 22.81%.In addition, the coatings of TSCSs also demonstrate good water resistance on the glass slide due to the closure shell and rough surface to prevent water from entering the pore and cavity.
