The impetus for the increasing interest in studying surface active ionic liquids (SAILs; ionic liquids with long-chain "tails") is the enormous potential for their applications, e.g., in nanotechnology and biomedicine. The progress in these fields rests on understanding the relationship between surfactant structure and solution properties, hence applications. This need has prompted us to extend our previous study on 1-(1-hexadecyl)-3-methylimidazolium chloride to 1-(1-alkyl)-3-methylimidazolium chlorides, with alkyl chains containing 10, 12, and 14 carbons. In addition to investigating relevant micellar properties, we have compared the solution properties of the imidazolium-based surfactants with: 1-(1-alkyl)pyridinium chlorides, and benzyl (2-acylaminoethyl)dimethylammonium chlorides. The former series carries a heterocyclic ring head-group, but does not possess a hydrogen that is as acidic as H2 of the imidazolium ring. The latter series carries an aromatic ring, a quaternary nitrogen and (a hydrogen-bond forming) amide group. The properties of the imidazolium and pyridinium surfactants were determined in the temperature range from 15 to 75°C. The techniques employed were conductivity, isothermal titration calorimetry, and static light scattering. The results showed the important effects of the interactions in the interfacial region on the micellar properties over the temperature range studied.

Ionic liquids, ILs, carrying long-chain alkyl groups are surface active, SAILs. We investigated the micellar properties of the SAIL 1-hexadecyl-3-methylimidazolium chloride, C(16)MeImCl, and compared the data with 1-hexadecylpyridinium chloride, C(16)PyCl, and benzyl (3-hexadecanoylaminoethyl)dimethylammonium chloride, C(15)AEtBzMe(2)Cl. The properties compared include critical micelle concentration, cmc; thermodynamic parameters of micellization; empirical polarity and water concentrations in the interfacial regions. In the temperature range from 15 to 75 degrees C, the order of cmc in H(2)O and in D(2)O is C(16)PyCl > C(16)MeImCl > C(15)AEtBzMe(2)Cl. The enthalpies of micellization, DeltaH(mic) degrees, were calculated indirectly from by use of the van't Hoff treatment; directly by isothermal titration calorimetry, ITC. Calculation of the degree of counter-ion dissociation, alpha(mic), from conductivity measurements, by use of Evans equation requires knowledge of the aggregation numbers, N(agg), at different temperatures. We have introduced a reliable method for carrying out this calculation, based on the volume and length of the monomer, and the dependence of N(agg) on temperature. The N(agg) calculated for C(16)PyCl and C(16)MeImCl were corroborated by light scattering measurements. Conductivity- and ITC-based DeltaH(mic) degrees do not agree; reasons for this discrepancy are discussed. Micelle formation is entropy driven: at all studied temperatures for C(16)MeImCl; only up to 65 degrees C for C(16)PyCl; and up to 55 degrees C for C(15)AEtBzMe(2)Cl. All these data can be rationalized by considering hydrogen-bonding between the head-ions of the monomers in the micellar aggregate. The empirical polarities and concentrations of interfacial water were found to be independent of the nature of the head-group.

Unintentional injuries are one of the leading causes of ill health, disability & death among the children and young adults worldwide. As these injuries are strongly related to social determinants, the burden falls mainly upon the Low- and Middle-Income Countries (LMICs) like Nepal. Thus, the main objective was to explore the epidemiology of unintentional childhood injuries in urban and rural areas of Kavrepalanchok district. A cross sectional analytical study was done in Bethanchok rural municipality and Dhulikhel municipality of Kavrepalanchok district. The respondents were interviewed using a pretested semi-structured questionnaire. The details of injuries sustained within the past 12 months were included. A total of 667 children aged 1–16 years were surveyed, among which 26% from rural and 17.2% from urban areas had unintentional injuries in the past 12 months. Falls were the most common mode of injury in both the areas. Similarly, the proportion of burn was more in rural area (16.1%) whereas, Road Traffic Injuries were more in urban area (12.5%). Majority of the injuries occurred at home (54.5%) while the child was playing (64.1%). Factors like child’s gender and place of residence affected the occurrence of unintentional injuries (p<0.05). Out of total injured children, 18 of them had not recovered and 11 were left with some form of permanent disability. As the rate and pattern of unintentional childhood injuries in the rural and urban area differ, the prevention strategies should focus on risk factors that apply to both the areas and awareness should be created among the parents and primary caregivers about the fact that childhood injuries are predictable and preventable.
