“…These observations indicate the participation of the pyrazole ring in coordination with the metal ion through the nitrogen atom [16]. Moreover, all the other function groups in both the ligand and its complex were sited in their expected regions [33], as can be seen in Figure 2.…”

“…The UV-Vis Job's method produced a one-to-one metal-to-ligand stochiometric ratio, which supported the presence of the expected 5 coordination structure since the ligand is considered to be tridentate. Additionally, several publications that have recently succeeded in resolving the XRD structures of similar complexes were used to support our assessment of whether the expected structure could be found [33][34][35][36]. To support the purity of the desired Co(II) complex, energy-dispersive X-ray (EDX) and PXRD analyses were performed, as can be seen in Figure 1.…”

The pyrazole-pyridin-2-amine, as a tridentate pyrazole ligand, and its neutral Co(II)/pyrazole complex were prepared using a direct method with a high yield. The desired pyrazole ligand and its complex were subjected to several physicochemical and thermal analyses; moreover, the DFT-like optimization of MEP, HOMO/LUMO, and TD-DFT correlated well with their experimental relatives. Additionally, the oxidation catalytic activities of the Co(II)/pyrazole complex, such as the catecholase of catechol to o-quinone and the phenoxazinone of 2-aminophenol to 2-aminophenoxazinone, were also evaluated under mild RT conditions and atmospheric oxygen.

“…As shown in Fig. 6 urea before subjecting to any stress has a crystalline structure with two sharp peaks at 22.58 o and 35.5 o , when subjected to stress the sharp peak at 35.5 o has become more broader and shifted to 35.22 o as the particle size has reduced (Table 2) and the crystalline structure has deformed (Hosny 2015). The crystallite sizes of compressed samples are smaller than common urea which will affect on their behavior in the static release experiments.…”

The increasing usage of slow release fertilizers has become an essential demand to save fertilizer consumption and reduce the environmental pollution. In this study, two different techniques were used to prepared slow release urea fertilizers (SRUFX and SRUFY) composed of urea, sawdust and gelatin as a binding material. The two prepared fertilizers were characterized by Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray (EDX) and X-Ray diffraction (XRD). Urea static release was studied and indicated a prolongation of the release pattern of urea with approximately three times by incorporating saw dust and gelatin. The kinetics of the static release showed that SRUFX and SRUFY follow non-fickian release. The effect mechanical stress (1, 1.5 and 2 MPa) on the release time of urea was studied and indicated an increase in time of release as the stress increases.

In this work, the adsorption characteristics of metal-organic frameworks (MOFs: and ZIF-8) with two different types of structure were analyzed. MOF-199 consists of copperbased metal clusters while the ZIF-8 consists of organic molecules interlaced with zinc atoms and these have octahedral morphology and typical rhombic dodecahedron shape, respectively. The results of phenol (Ph) and p-nitro phenol (PNP) adsorption capacity from aqueous solution show that MOF-199 has a higher adsorption capacity: Ph 79.55% and PNP 89.3%, while for ZIF-8 the adsorption capacity was Ph 65.5% and PNP 77.0%. Adsorption of phenols was fit to Langmuir, Sips and Redlich-Peterson models and kinetics by pseudosecond order. Gibbs free energy (ΔG°) shows that adsorption processes studied are spontaneous.
