“…The inorganic material is based on layered double hydroxide (LDH) due to its efficiency in controlling drug release at the molecular level in a sustained manner. LDH, anionic clay, has a positively charged hydroxide lattice, with the brucite structure and replaceable hydrated anions and H 2 O molecules in the interlayer [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. The LDH drug delivery system has been attracting the scientific community owing to its ease of preparation, improved drug bioavailability, stability, better pharmacological performance with no toxicity and, most importantly, good controllability on drug release in a sustained fashion [ 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 ].…”

Although nicotinic acid (NA) has several clinical benefits, its potency cannot be fully utilized due to several undesirable side effects, including cutaneous flushing, GIT-associated symptoms, etc. To overcome such issues and improve the NA efficacy, a new inorganic–organic nanohybrids system was rationally designed. For making such a hybrid system, NA was intercalated into LDH through a coprecipitation technique and then coated with Eudragit® S100 to make the final drug delivery system called Eudragit® S100-coated NA-LDH. The as-made drug delivery system not only improved the NA release profile but also exhibited good bio-compatibility as tested on L929 cells. Such an inorganic–organic nanohybrid drug delivery agent is expected to reduce the undesirable side effects associated with NA and hopefully improve the pharmacological effects without inducing any undesirable toxicity.

A novel adsorbent (ZA/SiO2) was prepared by blending urea mixture of ZnSO4 and Al2(SO4)3 while using SiO2 as a support form. The adsorption properties of ZA/SiO2 for the removal of toxic metal ions (Cu(II) and Cr(VI))from water were evaluated. By batch experiment method to investigate the ZA/SiO2 adsorption of Cu(II) and Cr(VI) solution treatment effect. The sorption kinetics curves of Cu(II) and Cr(VI) on ZA/SiO2 were L-shaped. What's more, the solid concentration effect was found in the process of sorption kinetics. Langmuir and Freundlich sorption isotherm models were used to analyze the adsorption data. The results showed that the adsorption conforms to Langmuir and Freundlich adsorption isotherm models. However, the adsorption capacity of ZA/SiO2 compounds for Cu(II) and Cr(VI) is greatly improved. The adsorption capacity of Cu(II) is 158 mg·g− 1 and of Cr(VI) is 176 mg·g− 1, which were 3.6 and 1.8 times of ZA, respectively. Density functional theory (DFT) was utilized for the analysis of intrinsic mechanism and specific pathways. It primarily involved isomorphic substitution of Cr(VI) and Zn(II) and the intercalation of Cr2O72−, with the exception of Cr(OH)3 precipitation. Conversely, Cu(II) removal's primary mechanism in water was isomorphic substitution, except for Cu(OH)2 precipitation.
