Abstract

In this study Mg/Al layered double hydroxides (LDHs) and organo-modified chiral LDHs were synthesized in one step under green conditions. Co-precipitation reaction of the Al(NO3)3·9H2O, Mg(NO3)2·6H2O and different biocompatible N,N-(pyromellitoyl)-bis-L-amino acids was carried out in aqueous solution in a short time by an ultrasonic technique. Field emission scanning electron microscopy and transmission electron microscopy techniques showed that the resulting products have good crystallinity and uniform morphology. The presence of the bioactive surfactants in the interlayer space of LDH was confirmed by Fourier transform infrared spectroscopy, X-ray diffraction (XRD) and thermogravimetry analysis techniques. As expected, the positions of the basal reflections in the XRD patterns of modified samples are shifted to higher d value indicating the expansion of the interlayer distance. Thermal properties were investigated by the thermogravimetric analysis technique.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
