“…This important result confirms that nano sized HAp crystals acts as photo-catalysts and induces photocatalytic processes (generation of OH. and O 2 − radicals on the surface of nano-HAp) under UV irradiation [25][26][27], which are responsible for enhanced dye degradation. However, at higher dye concentration, the percentage of radicals with respect to dye concentration remains low and may be responsible for lower degradation of dye.…”

Nanostructured bio-photocatalyst hydroxyapatite (HAp) was synthesized by a simple and productive wet chemical precipitation method to explore the photocatalytic performance of the material for degradation of Remazol Brilliant Blue R (RBBR) dye. Wet chemically synthesized nano-HAp was characterized through x-ray diffraction, Transmission electron microscope, scanning electron microscope, N 2 -adsorption-desorption, thermo gravimetric analyzer, Fourier transform infrared and UV-vis absorption techniques. Photocatalytic degradation of RBBR under ultraviolet irradiation was examined and ∼80% degradation was achieved in 120 min by using nano-HAp. The photocatalytic degradation followed Parabolic Diffusion kinetics. Fast degradation kinetics and removal of RBBR dye was achieved by nano-HAp due to modification of surface entities leading to suppression of photogenerated electron-hole recombination. This makes nano-HAp a remarkable bio-photocatalyst material for removing dyes from water.

“…With this simple, green and low-cost method, high-yield nanostructures were obtained at room temperature and at a frequency response of 20kHz. The sonochemical method, which is based on high-energy ultrasonic irradiation, creates a temperature of up to 500°C and a pressure of 50MPa within a few microseconds (53)(54)(55)(56)(57). The sonochemical method is preferred in synthesizing nano-sized materials and various colloidal systems (54,(58)(59)(60)(61)(62).…”

This study is a preliminary attempt to present the preparation and the first time a κ-carrageenan/PVA/eggshell nanostructure is used as a novel biodegradable and homogeneous nanostructure in cement composition. In order to clearly understand the effects these additives have on the mechanical properties of cementitious composites, they were synthesized in double and triple combinations and added into mortar mixtures. Three different cement mortar specimens were prepared by integrating the additives in ratios of 0, 0.1, 0.5 and 1% by cement weight and flexural and compressive strengths of the specimens were determined at the ages of 7 and 28 days. The flowability of the presented nanostructures was also discussed. The results revealed a 10–11% increase in both compressive and flexural strengths for the specimens prepared with the triple combination of the proposed additives. Moreover, strain capacity was enhanced as a result of the efficient dispersion of additives in the cement matrix.

“…Among a mass of N‐donor ligands, flexible bis (benzimidazol‐1‐yl)hexane ligands are excellent candidates for the construction of desired CPs, which can bend and rotate freely to accommodate the preferred coordination geometries of the metal centers . The organic multicarboxylate linkers can adopt diversiform coordination modes, which are beneficial for binding with metal centers to construct multidimensional CPs with graceful topologies …”

Two new ternary metal coordination polymers (CPs), namely, {[Co2(BTC)(L)]·0.25H2O}n (1) and [Ag(HIPA)(L)]n (2) (H4BTC = 1,2,3,4‐butanetetracarboxylic acid, H2IPA = isophthalic acid, L = 1,6‐bis(5,6‐dimethylbenzimidazol‐1‐yl)hexane) were hydrothermally synthesized and characterized by elemental analysis, infrared spectroscopy, single‐crystal X‐ray diffraction, and powder X‐ray diffraction (PXRD). 1 exhibits unusual 2D network with point symbol {43.63}2{46.66.73}. 2 possesses 1D chain structure which is further extended into a 3D supramolecular network via O–H···O hydrogen‐bonding and π–π stacking interactions. 1 and 2 can selectively detect benzaldehyde (BZH), Fe3+ (just 1) and Cr2O72− (just 2) ions in water via the luminescence quenching process. Furthermore, the photocatalytic activities of two CPs were evaluated for degradation of methylene blue (MB) and methyl violet (MV) under UV irradiation.
