“…Since feed iodine concentrations in the groups with potassium iodide were not consistently lower than in the iodate groups no considerable iodine losses occurred at the storage time of maximal 4 weeks and the existing storage conditions. In contrast to studies with salt describing losses of up to 30% at application of potassium iodide (Waszkowiak and Szymandera-Buszka, 2007) the reductive medium of the concentrate or low humidity, temperatures and oxygen access may have avoided iodide losses in the present study. For that reason possible effects of the iodine species may just occur due to differences in metabolism.…”

“…In the EU sodium iodide, potassium iodide, calcium iodate hexahydrate and calcium iodate anhydrous are accredited for application to animal feed (EU, 2005). Furthermore the utilization of iodide may also cause lower iodine contents of blood, urine and faeces due to higher storage losses compared to iodate (Waszkowiak and Szymandera-Buszka, 2007).…”

“…This might be due to the effect of heat on the iodine content. Or it might be due to the halogen nature of iodine and its exposure to excess oxygen and carbon dioxide slowly oxidizes it to metal carbonate and elemental iodine which then evaporates [29]. …”

“…Out of the total households with the trend of buying iodized salt, 26.8% of the households had inadequately iodized salt. The explanation for this might be due to loss of iodine because of exposure to heat, sunlight, and moisture during storage at home or elsewhere in the supply chain [28, 29]. But also people may not get the appropriate product for the payment they make.…”

Background Universal use of iodized salt is a simple and inexpensive method to prevent and eliminate iodine deficiency disorders like mental retardation. However, little is known about the level of adequately iodized salt consumption in the study area. Therefore, the study was aimed at assessing the proportion of households having adequately iodized salt and associated factors in Wolaita Sodo town and its peripheries, Southern Ethiopia. Methods A cross-sectional study was conducted from May 10 to 20, 2016, in 441 households in Sodo town and its peripheries. Samples were selected using the systematic sampling technique. An iodometric titration method (AOAC, 2000) was used to analyze the iodine content of the salt samples. Data entry and analysis were done using Epi Info version 3.5.1 and SPSS version 16, respectively. Result The female to male ratio of the respondents was 219. The mean age of the respondents was 30.2 (±7.3 SD). The proportion of households having adequately iodized salt was 37.7%, with 95% CI of 33.2% to 42.2%. Not exposing salt to sunlight with [OR: 3.75; 95% CI: 2.14, 6.57], higher monthly income [OR: 3.71; 95% CI: 1.97–7.01], and formal education of respondents with [OR: 1.75; 95% CI: 1.14, 2.70] were found associated with the presence of adequately iodized salt at home. Conclusion This study revealed low levels of households having adequately iodized salt in Wolaita Sodo town and its peripheries. The evidence here shows that there is a need to increase the supply of adequately iodized salt to meet the goal for monitoring progress towards sustainable elimination of IDD.

“…As the reaction proceeded, we found that the size of the truncated octahedra would grow with reaction time. [24][25][26] As the energy of the facets is E {100} > E {111} , [14,27] I À will preferentially etch the {100} facets of the NCs. After 15 min, the size of the nanoparticles reached approximately 50 nm.…”

Growth of Concave Polyhedral Pd Nanocrystals with 32 Facets Through In Situ Facet‐Selective Etching

The control over crystal-plane exposure of nanoparticles in a variety of shapes and material types (such as metals and metal oxides) has attracted much attention because fascinating properties might be accomplished. [1][2][3] In the case of metallic nanocrystals (NCs), it has been demonstrated that the exposed crystal facets of metallic NCs have a large influence on their catalytic reactivity and selectivity. [4][5][6][7] Recent studies indicate that high-index facets of a face-centered cubic (fcc) metal (e.g., Pd, Pt, and Au) generally exhibit significantly enhanced catalytic activity toward specific reactions compared to low-index facets because of a high density of low-coordinated surface atoms. [8][9][10][11][12][13] However, up to date, studies on the design and synthesis of metallic nanostructures enclosed by high-index facets are still insufficient. High-index facets usually disappear during the growth of NCs due to their high surface energies. [14] However, recent studies have shown that the exposure of high-index facets could be realized by tuning the growth kinetics, [15,16] the selective adsorption of specific chemical species, [17][18][19][20] and their epitaxial growth from seeds terminating in high-index facets. [21,22] Herein, we report a synthetic strategy that allows the highyield fabrication of concave polyhedral Pd NCs with 32 facets that are rich in atomic steps and defects on the surface. This nanostructure was successfully prepared through an in situ facet-selective etching growth route. The vital role that iodide ions (I À ) together with ethanolamine as the surface controller play in the formation of concave polyhedral Pd NCs having catalytic active sites is demonstrated. The concave polyhedral Pd NCs exhibit significantly enhanced specific and mass activities towards the electrooxidation of ethanol in comparison to truncated octahedral Pd NCs and commercial Pd black catalysts with low-index facets.In a typical synthesis of concave polyhedral Pd NCs, poly-(vinyl pyrrolidone) (PVP, M W = 30 000), NaI, and an aqueous Na 2 PdCl 4 solution were mixed together with ethanolamine. The resulting homogeneous solution was transferred to a Teflon-lined stainless-steel autoclave with a capacity of 12 mL. The sealed vessel was then heated at 200 8C for 6 h before it was cooled to room temperature (see the Experimental Section for synthesis details). The resulting products were collected by centrifugation and washed several times with water and ethanol.The representative electron microscopic images of the asobtained Pd NCs are shown in Figure 1. As depicted by transmission electron microscopic (TEM) images in Figure 1 a and Figure S1 c and d in the Supporting Information, the product consists of well-shaped NCs with a yield above 90 % and an average apex-to-apex distance of 50 nm. The nanoparticles display a darker contrast in the center compared to the edges, indicating the possible presence of concave features in the NCs. The scanning electron microscopic (SEM) images shown in Figure 1 b and Figure S1...
