Dye degradation and antibacterial activity of green synthesized silver nanoparticles using Ipomoea digitata Linn. flower extract

Abstract: A new greener approach for the synthesis and stabilization of silver nanoparticles using aqueous flower extract of Ipomoea digitata Linn. is reported in this study. The nature of silver nanoparticles was analyzed by various techniques. The silver nanoparticles produced a peak centered near 412 nm which confirmed the synthesis. Scanning electron microscopy portrayed the polydispersed nature of the nanoparticles, and a distinct peak at 3 keV in energy-dispersive X-ray spectrum confirmed the elemental silver. X-ray diffraction studies showed the presence of 111 reflection plane of a face-centered cubic structure. The zeta potential value was − 25.1 mV which substantiated the stability of the nanoparticles. The antibacterial potential of silver nanoparticles was verified using well diffusion method. The silver nanoparticles appreciably inhibited growth of multi-drug resistant bacteria like Escherichia coli and Staphylococcus epidermidis. The nanoparticles also exhibited a good catalytic reduction for methylene blue dye in the presence of NaBH4. It followed a pseudo-first order kinetics with a rate constant of 0.1714 min−1.

Exploring the Brønsted acidity of UiO-66 (Zr, Ce, Hf) metal–organic frameworks for efficient solketal synthesis from glycerol acetalization

Abstract: Zr, Ce, Hf-based isostructural UIO-66 MOFs exhibited varying degree of Bronsted acidity (UiO-66(Hf) > UiO-66(Ce) > UiO-66(Zr)) on their secondary building units owing to the differences in their oxophilicities. UIO-66(Hf) showed remarkable catalytic activity for solketal synthesis with a turnover frequency as high as 13 886 h−1, which is 90 times higher than that of UiO-66(Zr) and several orders of magnitude higher than that of H2SO4 or Zeolites.

Awareness of palliative care among diploma nursing students

Abstract: Background: The goal of palliative care is not to cure, but to provide comfort and maintain the highest possible quality of life for as long as life remains. The knowledge of nurses influences the quality of care provided to these patients. The present study aimed at identifying the level of knowledge and attitude of nursing students who are the future caretakers of patients, which helps to make recommendations in incorporating palliative care concepts in the nursing curriculum. Objectives: (1) To assess the level of knowledge of nursing students on palliative care; (2) To identify the attitude of nursing students towards palliative care; (3) To find the correlation between the knowledge and attitude of nursing students; (4) To find the association between nursing students' knowledge, attitude and selected demographic variables. Materials and Methods: A correlative survey was carried out among 83 third-year Diploma Nursing students by using cluster sampling method from selected nursing schools of Udupi district. Results: The data analyzed showed that the majority (51%) of them was in the age group of 21years and 92% of them were females. Only 43.4% of them were aware of the term palliative care and it was during their training period. The data showed that 79.5% of students had poor knowledge (6.4± 1.64) on palliative care and 92.8% of them had favorable attitude (56.7± 8.5) towards palliative care. The chi-square showed a significant association between knowledge and age (χ 2 =18.52, P Conclusion: Palliative care aspects should be incorporated in the diploma nursing curriculum.
