Mac OS X: How to configure a VPN Connection / establish a connection to a VPN Network under macOS (Virtual Private Network) Structural, optical, and gamma radiation safety properties of 46V 2O 5♴6P 2O 5·(8– x)B 2O 3The default file type to load is the.![]() ![]() The amount of B 2O 3 within this composition was decreased and the same ratio of ZnO was inserted. xZnO ( x = 0, 2, 4, 6, and 8 mol %) abbreviated as VPB/Zn glasses. To achieve these aims, the following items have been carried out:ZnO·V 2O 5·P 2O 5♻ 2O 3 glasses have been synthesized.The structure of the synthesized glasses has been examined.UV–Vis–NIR measurements of the proposed glasses were performed.Optical characteristics such as optical energy bandgap, refractive index, and Urbach’s energy have been determined.The mass attenuation coefficient (MAC) and equivalent atomic number ( Zeq) were determined.The γ-rays buildup factors: energy absorption buildup factor (EABF) and exposure buildup factor (EBF) have been evaluated for the synthesized glasses.Composition of the basic glass structure containing high ratios of vanadium and phosphate were determined as 46V 2O 5♴6P 2O 5·(8– x)B 2O 3 The main objective of this study is to investigate the UV–Vis–NIR spectroscopy and FTIR properties and evaluate the γ-rays shielding competence of ZnO·V 2O 5·P 2O 5♻ 2O 3 to be applied in optoelectronic and medical applications alternative for traditional materials. Formerly, structure, UV–Vis spectroscopy, thermal, electrical, and radiation shielding properties of vanadium–boron glasses with different compositions have been reported. Therefore, ZnO controls the refractive index of the synthesized glasses. Table 1 includes the fractional abundance and density of the synthesized glasses.As clearly seen from this spectrum, the formation of two intense regions was observed. An optical image of the synthesized glasses is shown in Fig. The formation processes of the glasses synthesized with the classic melt quenching method are as follows:Weighing of the chemicals according to the compositions of the glass samples and their mechanical mixing and stirring,Placement of the prepared powdered samples in a high temperature furnace inside a porcelain crucible at room temperature.Increasing the temperature of the high temperature furnace from room temperature to 1100 ☌ and melting period (60 min),Transferring the molten samples into a stainless steel mold and keeping them inside a quenching furnace at 400 ☌ (60 min),Processes of cutting, polishing and powdering for the required measurements.In addition to these processes, when samples were taken out of the high temperature furnace, crucibles were periodically mixed mechanically, and formation of uniform glass structures was achieved. Glass compositions were named as VPB8, VPB6Zn2, VPB4Zn4, VPB2Zn6, and VPZn8. The bands found in the region of 439–452 cm −1 are thought to belong to ZnO 4 vibrations except for VPB8 sample. In the first region, the band located at 376–397 cm −1 was assigned to the vibrations of Zn 2+, Zn–O vibration in the ZnO 4 tetrahedral structures or bending vibrations in VO 5 structural units. Apart from these, in the 500–700 cm −–1500 cm −1 regions, two regions with lower intensity than the two previously mentioned regions were observed. ![]() It was observed that these structural units disappeared with addition of ZnO. In 945 cm −1, only VPB8 glass network had symmetrical stretching vibrations of isolated VO 2 groups within the VO 4 structural units. These modes were B–O stretching vibrations in BO 4 units, stretching vibrations of VO 5, and asymmetric stretching mode of P–O–P. Microsoft internet explorer for mac download 2011It is known from the literature that the band located in the region of 1117–1159 cm −1 corresponds to the P–O – groups and B–O vibrations in penta- and di-borate groups for all synthesized glasses. While the region between 10 cm −1 was related both to asymmetric stretching modes of (PO 3) 2− and to symmetric stretching vibrations of (PO 2), this region might also belongs to the stretching vibrations of P–O–Zn except for VPB8. This may be the evidence that nonbridging oxygen creates bonds with the elements in the glass structure such as V 2O 5 and ZnO. Interestingly, this band disappeared in VPB2Zn6 glass network.
