“…The extremely short chain of the ligand and the solvated carboxylic acid dimer facilitated in the engineered aq SA PQDs likely caused this large strain. Peaks due to Pb(OH) 2 (2θ = 22.8°) could not be detected, indicating the absence of this phase , in aqueous medium. The XRD analysis thus supports the retained crystal phase of PQDs after the ligand exchange and phase transfer.…”

Perovskite quantum dots (PQDs) offer high photoluminescence quantum yields; however, due to their limited stability in aqueous media, to date their utilization in biomedical applications has been limited. The present work demonstrates highly fluorescent and stable aqueous PQDs that were synthesized using a facile engineered phase transfer method. Ligands were engineered to have a dual functionality, i.e., they could simultaneously mediate the strong binding of PQDs and the interactions with water molecules. The resultant water-soluble PQDs demonstrated robust structural and optical properties. The extracted aqueous PQDs remained stable in pellet form for 8 months, which was the entire test duration. Notably, 100% of their fluorescence was also retained. As a proof-of-concept experiment, the water-soluble PQDs were successfully tagged to polyclonal antibodies and used to image Escherichia coli cells in aqueous media. No structural or optical disturbance in PQDs was detected throughout the process. This work marks the beginning of the use of nonpolymeric aqueous PQDs and shows their strong potential to be used in biological applications.

“…However, to our knowledge, very few studies concerning their synthesis and analysis of characterization are reported in literature. Indeed, we found that barium hydroxide nanoparticles are obtained by means of a top down process, by following a milling procedure [15], or by two different chemical precipitation processes [16,17]. Similarly scarce literature is found on the synthesis of Sr(OH) 2 nanoparticles, involving a chemical precipitation process from salt solutions [18,19].…”

The objective of this paper is to introduce a patented and eco-friendly method to synthesize aqueous suspension of all types of alkaline-earth metal hydroxides nanoparticles (NPs). This method is based on an ion exchange process; the exchange takes place at ambient temperature/pressure, starts from cheap or renewable reagents and, in one single step, results in the creation of the crystalline desired nanoparticles in only a few minutes. In terms of structural and morphological features, the synthesized nanoparticles are characterized by means of XRD-Rietveld refinement, FTIR, and TEM. In particular, we obtained pure and crystalline magnesium and calcium hydroxide suspensions, showing the typical brucite crystal structure with a hexagonal lamellar morphology and dimensions generally <100 nm. With respect to the strontium and barium hydroxide suspensions, we observed different kinds of hydroxides (either anhydrous and hydrate forms), characterized by orthorhombic or monoclinic crystal lattices with rod-like nanostructured morphologies. Despite the different morphologies, all synthesized nanoparticles appear constituted by a superimposition of primary nanoparticles, of dimensions ranging from a few to 15 nm, correlated to the increase in the atomic number of the alkaline earth metal.

“…It can be used to color ceramics, as a catalyst, as an alternative to the bordeaux mixture, nematicide. Cu(OH)2 is also occasionally used as ceramic colorant, combined with latex paint, making a product designed to control root growth in potted plants [8,9]. Synthesis of Cu(OH)2 nanoparticles attracted increased attention due to reliable low cost, specific size, well-defined morphologies and wide range of potential applications.…”

“…Copper compounds are one of the most normal conductors in modern technologies and could be used widely in nano device. Therefore, the development of uniform copper compound nanoparticles has been intensively pursued [8]. Copper hydroxide [Cu(OH)2] nanoparticle is one of the copper compounds and it has many applications.…”

Silver oxide (Ag2O) and copper(II)hydroxide (Cu(OH)2) nanoparticles were synthesized through a simple solution reduction method using silver nitrate (AgNO3) and copper sulphate pentahydrate (CuSO4.5H2O) in the presence of sodium hydroxide (NaOH) as reducing agent. X-ray diffraction (XRD) analysis, scanning electron microscopic (SEM) analysis, Fourier transform infrared spectroscopic (FT-IR) analysis, UV-absorption and photoluminescence (PL), vibrating sample magnetometer (VSM) studies were performed to confirm the size distribution measurement, surface morphology, optical and magnetic properties of the synthesized samples. Silver nanoparticles synthesized in the form of Ag2O and copper in the form of Cu(OH)2 was confirmed by the XRD study. The UV-Vis absorption analysis indicates that the absorption peak for Ag2O in the lower wavelength region of the optical spectrum. The sharp intensity peaks in the FTIR spectrum of Ag2O and Cu(OH)2 indicate the stretching and bending frequencies of the molecular functional groups in the samples as well as their high crystalline nature. The SEM images show the shape of Ag2O nanoparticles is nearly spheroid. The VSM study of Cu(OH)2 shows ferromagnetic interaction at room temperature. The antibacterial properties of Ag2O and Cu(OH)2 on Staphylococcus aureus and Escherichia coli indicate that both the samples are effective on Staphylococcus aureus, which is concentration dependent.
