“…The interlayer spacing was much larger than the original 1.24 nm of MMT, which gave direct evidence that the SbQ molecules had been intercalated into MMT. From the TGA curves (Figure 4 B), the amount of SbQ in the MMT interlayers was about 7.57% (35.71 meq/100 g) [ 12 ], which is less than the cation exchange capacity of the sodium MMT.…”

“…MMT is one of the smectite group having two silica tetrahedral sheets layered between an alumia octahedral sheet. In nature, the charge imbalance in the structure is neutralized by adsorption of sodium or calcium ions in the interlayer, which makes intercalation possible by cation exchange with metallic/organic cations [ 12 ]. MMT has attracted a great deal of attention in recent years for drug delivery applications due to its good physical and chemical properties [ 10 ].…”

A facile synthesis of a styrylpyridinium salt (SbQ)/montmorillonite (MMT) via cationic exchange interactions between styrylpyridinium species (specifically SbQ) and MMT platelets is reported in this work. The SbQ-MMT solutions were irradiated under ultraviolet (UV) light for a specific time to obtain the cross-linked SbQ-MMT materials. Scanning electron microscopy and atomic force microscopy analyses revealed the structures and morphologies of MMT and modified MMT. X-ray diffraction and transmission electron microscope analyses indicated that the basal spacing increased from 1.24 to 1.53 nm compared with the pristine MMT, which proved that SbQ had interacted with MMT. Thermal gravimetric analysis curves showed that the amount of SbQ in the MMT interlayers was 35.71 meq/100 g. Fourier transform infrared spectroscopy also confirmed the intercalation of SbQ species into MMT interlayers, and UV spectroscopy was used to follow up the cross-linking of SbQ-MMT. This novel material has potential applications in drug delivery, and it can also be used as an additive to improve the mechanical properties of polymers.

In this study, the CuS nanoparticles loaded on activated carbon (CuS-NPs-AC) composite was synthesized and then, characterized by XRD and FE-SEM analyses. The prepared composite was used as a potential adsorbent for the simultaneous ultrasound-assisted removal of Indigo Carmine (IC) and Safranin-O (SO). The CuS-NPs-AC dose (0.01-0.03 g), sonication time (1-5 min), initial SO concentration (5-15 mg L -1 ) and initial IC concentration (5-15 mg L -1 ) as expectable effective parameters were studied by central composite design (CCD) under response surface methodology (RSM) to obtain an useful knowledge about the effect of simultaneous interaction between IC and SO on their removal percentage. The optimum SO and IC removal percentages were determined to be 98.24 and 97.15% at pH = 6, 0.03 g of the CuS-NPs-AC, 3 min sonication time, 12 and 10 mg L -1 of IC and SO. The values of coefficient of determination (R 2 ) for SO and IC were 0.9608 and 0.9796, respectively, indicating the favorable fitness of the experimental data to the second order polynomial regression model. The isotherm data were well correlated with Freundlich model. The maximum monolayer adsorption capacities of 87.5 and 69.90 mg g -1 at room temperature for IC and SO in the investigated binary system expressed the high efficiency of the novel adsorbent for water cleanup within a short time. The investigation of correlation between time and rate of adsorption revealed that IC and SO adsorption onto the CuS-NPs-AC followed pseudo-second-order and intra-particle diffusion simultaneously.

“…Clay minerals have been suggested as suitable inorganic hosts of fluorescent compounds to develop latent fingermarks . They can keep cationic fluorescent species within their interlayer space, and a suitable layer charge density of the clay minerals could provide an isolated environment for each cationic fluorescent species, leading to improved photophysical properties with reduced concentration quenching .…”

Development of Latent Fingermarks on Nonporous and Semiporous Substrates Using Photoluminescent Eu(Phen)₂ Complex Intercalated Clay Hybrids with Enhanced Adhesion

In forensic science, developing latent fingermarks using powders is a critical, general method to identify individuals. Photoluminescent Eu(Phen) complex intercalated clay hybrids have been used to improve the visualization of fingermarks on nonporous (glass and polymer film) and semiporous (euro and dollar banknotes) substrates. An ion exchange reaction has been successfully used to intercalate Eu(Phen) complex ions into the interlayer spacing of two different Na -clays, Na -montmorillonite and Na -hectorite, with different primary particle sizes. To change the surface properties of the obtained hybrid to be more lipophilic, the hydroxyl groups at the edge of the hectorite hybrid were modified with hexadecyltrimethoxysilane via silylation. We investigated the correlation of the size and surface properties of the hybrids with their adhesion to fingermark residues. Fingermarks were successfully visualized using hybrids under UV illumination. In particular, ridge details on semiporous substrates can be more clearly seen using hybrids with smaller primary particles and greater lipophilicity.
