“…A common technique to improve dispersion and achieve optimum utilization of CNTs is through chemical functionalization, which enables chemical bonding between the CNTs and material of interest. Both covalent6–10 and noncovalent11–15 functionalization methods have been employed to impart solubility and chemical modifications to CNTs. Generally, the linkage of small or large molecules to CNTs by covalent methods is more stable and effective because grafted molecules raise the solubility of CNTs even with a low degree of functionalization 16–19.…”

The nanohybrids composed of silver nanoparticles and aromatic polyamide functionalized multiwalled carbon nanotubes (MWCNTs) is successfully synthesized and tested for their antibacterial activity against different pathogens. Prior to deposition of silver nanoparticles, acid treated MWCNTs (MWCNTs-COOH) were successively reacted with p-phenylenediamine and methylmethacrylate to form series of NH 2 -terminated aromatic polyamide dendrimers on the surface of MWCNTs through Michael addition and amidation. Existence of high abundance of amine groups on the surface of functionalized MWCNTs (f-MWCNTs) provided sites for formation of silver nanoparticles by the reduction of aqueous solution of AgNO 3 . The silver nanoparticles formed in the resulted f-MWCNTs-Ag nanohybrids were determined to be face centered cubic (fcc) symmetry. The structure and nature of f-MWCNTs and f-MWCNTs-Ag nanohybrids were characterized by UV-vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction analysis (XRD), Raman spectroscopy and thermogravimetric analysis (TGA). The dispersion state of f-MWCNTs and immobilization of silver nanoparticles on the surface of f-MWCNTs were investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Elemental composition of f-MWCNTs-Ag nanohybrids was determined by energy dispersive X-ray spectroscopy (EDS). The antimicrobial activity of fMWCNTs-Ag nanohybrids were estimated against E. coli, P. aeruginosa and S. aureu and compared with MWCNTs-COOH and f-MWCNTs. The results indicate that functionalization of MWCNTs with aromatic polyamide dendrimers and successive deposition of Ag nanoparticles could play an important role in the enhancement of antimicrobial activity.

“…QRs are of great interest for fundamental research and are highly promising novel materials for new technology. , However, QR properties will also depend on the quality of their internal crystal structure because may also exhibit decreased Auger recombination rates compared to those of QDs, which makes them potentially useful for advanced optoelectronic devices. Many modern methods have been developed for the synthesis of one-dimensional QRs. , However, these preparation processes often need a relatively high temperature, vacuum, complexity, and so forth; solvothermal synthesis offers great advantages of low cost and maneuverability. − In this research, we demonstrate a simple, fast, and “green” lead-free high-quality perovskite-type CsSnX 3 with a uniform QR-shaped structure for enhancing photovoltaic efficiency. To our knowledge, this is the first example of solvothermal synthesis of high-quality CsSnX 3 QRs with finely tunable photoluminescence (PL) and uniform diameters and high-performance solar cells up to 13%.…”

Herein, the fabrication of a lead-free cesium tin halide perovskite produced via a simple solvothermal process is reported for the first time. The resulting CsSnX (X = Cl, Br, and I) quantum rods show composition-tunable photoluminescence (PL) emissions over the entire visible spectral window (from 625 to 709 nm), as well as significant tunability of the optical properties. In this study, we demonstrate that through hybrid materials (CsSnX) with different halides, the system can be tunable in terms of PL. By replacing the halide of the CsSnX quantum rods, a power conversion efficiency of 12.96% under AM 1.5 G has been achieved. This lead-free quantum rod replacement has demonstrated to be an effective method to create an absorber layer that increases light harvesting and charge collection for photovoltaic applications in its perovskite phase.

“…Similarly homogeneous electrodeposition of Ni nanoparticles on 4-nitroaniline radical monolayer grafted on MWCNT was reported by Jin et al [3]. There have been reports of employing stringent conditions such as microwave irradiation [26], hydrothermal [27], solvothermal [28], chemical vapor deposition [29], electrophoretic deposition [30], etc. for the uniform distribution of metal/metal oxides on CNTs.…”
