The kinetics of mixed Ni-Al layered double hydroxide (LDH) precipitate formation on a soil clay fraction was monitored using X-ray absorption fine structure (XAFS) spectroscopy. The kinetic behavior was monitored at pH 6.0, 6.8, and 7.5 in order to determine the effect of reaction pH on precipitate formation. XAFS analyses were performed on a Ni-reacted whole soil at pH 7.5 to determine the eff...

NiAl layered double hydroxides (LDHs) are promising bifunctional catalysts comprising tunable redox and Lewis acidic sites. However, most studies of LDH employ alkali hydroxide carbonate precipitants which may contaminate the final catalyst leach into reaction media. Here, we report an alkali-free route to prepare NixAl LDHs with a composition range x = 1.7 4.1 using (NH4)2CO3 NH4OH as precipit...

Imaging complex vascular structures by X-ray microcomputed tomography (μ-CT) is becoming vital for research purposes in pathology of diseases. Acrylic-based polymerizable resins are widely adopted the contrast agent to prepare pathological specimens imaging structures. For at higher resolution, it promising develop inorganic-type agents with attenuation coefficient as well low viscosity, homoge...

This work focuses on studying the removal of Titan Yellow (TY) dye, which is a water pollutant using three matrices layered double hydroxide (LDHs; M+2Al-HT), with M+2 = Ni, Co, or NiCo were synthesized co-precipitation technique in solution constant pH. The X-ray diffraction (XRD) pattern formed solids shows that phase LDH type average interlamellar distance (dspacing ≈ 7.595 Å). Fourier-trans...

In article 1600229, Shilong Wang, Rongrong Zhu, Yechang Qian, and co-workers investigate the anti-metastatic and anti-angiogenic effects of SiO2@LDH (LDH: layered double hydroxide) loaded with etoposide (VP16). SiO2@LDH has very suitable qualities as drug delivery agent and enhances the anti-metastatic action of VP16 both in vitro and in vivo. Enhanced anti-angiogenic efficacy is also proven wh...

Hollow nanoshells of layered double hydroxide (LDH) have been fabricated using exfoliated LDH nanosheets as a shell building block and polystyrene beads as a sacrificial template.
