“…In addition, LDH-2 still retained the original layered structure as seen for structure I in LDH-1. This result confirmed the partial exchange of NO 3 anions by the 2 nm-sized dodecyl sulfate anions as seen in previous reports [43,44]. Very interestingly, the intercalation in the CMC cluster causes a significant The HRTEM image of Mo 6 @LDH-2 shows black areas assigned to the aggregated Mo cluster anion ( Fig.…”

A new layered double hydroxide (LDH)-based nanocomposite functionalized with an octahedral molybdenum atom cluster (MC) exhibiting prominent photoactive and oxidation properties was synthesized. Zn-Al LDH and Zn-Al LDH intercalated dodecyl sulfate compounds (abbreviated as LDH-1 and LDH-2 respectively) were prepared by the co-precipitation method in an aqueous solution. The MCs were simply introduced into the LDH-2 by an anion exchangeable method in dimethylformamide under ambient conditions. The extension of the basal spacing of the LDH-1 from 0.9 nm to about 5 nm by intercalating dodecyl sulfate and Mo 6 cluster was confirmed by several complementary technics. The octahedral structure of the Mo 6 cluster was retained after promising candidate as a heterogenized homogeneous catalyst for removing organic pollutants.

“…It was modeled by the second type of universal power law ( Eq. (10) ) [ 31 , 32 , 33 ]. The dielectric properties of anionic clay (LDH) in both the Nyquist and Bode diagrams will be determined by the relaxation mechanism which can be achieved by either intra-cluster or inter-cluster charge recombination of water molecule, or other routes (NO 3 − ) as result of applied electric field in the frequency range [34] .…”

In this study, Zn3AlCl ionic clay was used to investigate the adsorption mechanism of the nitrate ions in solutions containing nitrate ions at different contact time. The clay was synthesized by coprecipitation method at room temperature, and this sample was characterized by XRD, Fourier transform-infrared (FT-IR) and inductively coupled plasma (ICP). This sample was crystallized in a rhombohedral symmetry (Space group: R-3 m). Impedance spectroscopy was used as a tool to evaluate and monitor the adsorption process at different contact time 5; 10; 20; 30; 60 min and the clay alone. The impedance measurement was well analyzed and fitted with an equivalent circuit containing both (R//CPE) connected in series. Furthermore, the σac conductivity was also investigated as a function of frequency. It was analyzed and fitted using double power law: σac(ω)=σdc+Aωs1+Bωs2,(0≤s1≤1and0≤s2≤1).This study reveals the existence of two relaxation processes with different relaxation times, which could be attributed to the grain and grain boundaries, and exhibit high values of dielectric constant at low frequencies.

“…The first thermal decomposition which lies at 107 °C with a loss of 0.8% normally comes from water adsorption. The second and third thermal events with 23–49% weight loss are referring to the oxidation of the total alkyl chain of dodecyl sulfate anions that are present in SDS [ 16 ]. The last stage, corresponding to 3.58%, may be related to metallic sulfate formation, similar to the SDBS compound.…”

Reports on fungicide-based agronanochemicals in combating disastrous basal stem rot disease in the oil palm industry are scant. Herein, we describe the potential of fungicide nanodelivery agents based on hexaconazole-micelle systems produced using three different surfactants; sodium dodecylbenze sulfonate (SDBS), sodium dodecyl sulfate (SDS) and Tween 80 (T80). The resulting nanodelivery systems were characterized and the results supported the encapsulation of the fungicide into the micelles of the surfactants. We have investigated in detail the size-dependent effects of the as-synthesized micelles towards the inhibition growth of Ganoderma Boninense fungi. All the nanodelivery systems indicate that their size decreased as the surfactant concentration was increased, and it directly affects the fungal inhibition. It was also found that Tween 80, a non-ionic surfactant gave the lowest effective concentration, the EC50 value of 2, on the pathogenic fungus Ganoderma boninense compared to the other anionic surfactants; SDBS and SDS. This study opens up a new generation of agronanofungicide of better efficacy for Ganoderma disease treatment.
