“…With increasing concerns of bacterial infections, there is a growing need to develop new and powerful antibacterial agents. In this direction, already nanoparticles have been applied in food preservation [4], burn dressings [5], safe cosmetics [6], medical devices [7], water treatment [8] and other range of products [9][10][11][12][13], due to its excellent antibacterial activity on several gram positive and negative bacteria [14]. There are various parameters that can affect the bactericidal property of the nanoparticles, namely size, shape, morphology, stability and surface functionalization.…”

Asian Ceram. Soc. (2015), http://dx. a b s t r a c tIn this work, we report a novel, economical, low temperature solution combustion synthesis (SCS) method to prepare ␣-Al 2 O 3 (Corundum) nanoparticles. Powder X-ray diffraction (PXRD), field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HR-TEM), Fourier transform infrared spectroscopy (FT-IR), BET surface area and ultraviolet visible spectroscopy (UV-vis) measurements were used to characterize the product. Antibacterial studies were examined against gram −ve Klebsiella aerogenes, Escherichia coli, Pseudomonas desmolyticum and gram +ve Staphylococcus aureus bacteria by agar well diffusion method. The ␣-Al 2 O 3 nanoparticles showed substantial effect on all the four bacterial strains. Photoluminescence (PL) measurements under excitation at about 255 nm show that the alumina nanoparticles have emission peaks at 394 and 392 nm.

“…It was reported that the TiO 2 nanoparticles can form spider-net like electrospun nylon-6 fiber mats, which can lead to a remarkable increase in the number of reactive sites with a corresponding improvement in hydrophilicity, photocatalytic and antimicrobial activity [112,113]. It was also reported that the preparation of a novel nylon-6/TiO 2 organic-inorganic nanocomposite material in the form of an electrospun mat, containing two distinct types of fibers (nano and sub nanosized) loaded with TiO 2 nanoparticles, with superior mechanical strength, high hydrophilicity, and good antimicrobial as well as UV blocking ability.…”

Abstract:Electrospinning is a highly versatile technique to prepare continuous fibers with diameters of the order of nanometers. The remarkable high aspect ratio and high porosity bring electrospun nanofibers highly attractive to various nanotechnological applications such as filtration membranes, protective clothing, drug delivery, tissue-engineering, biosensors, catalysis, fuel cells and so on. In this review, we collectively summarized the recent progress in developments of the electrospun ultrafine polyamide-6 based nanofibers preparation, characterization and their applications. Information of this polyamide-6 and composites together with their processing conditions for electrospinning of ultrafine nanofibers has been summarized in this review. The recent developments made during last few years on these materials are addressed in this review. We are anticipating that this review certainly drive the researchers for developing more intensive investigation for exploring in many technological areas.

“…Ag/titanium materials have particular attention for their low cost and the superior properties of silver [9]. On the other hand, the main advantage of TiO 2 nanotubes is their high surface area that enhances the photocatalytic/adsorption processes; at the same time, the silver presence inhibits the hole/electron recombination that enhances the photoactivity regarding the well-known P25-Degussa.…”

The photocatalytic degradation/adsorption process of the -blocker atenolol (ATL) under UV irradiation is described using two types of silver decorated catalysts: silver/titania and silver/titanates. The silver ions were reduced on the surface of TiO 2 -P25-Degussa using gallic acid. Silver/titanates were prepared by a microwave-assisted hydrothermal method using the silver/titania as the starting material to obtain the hydrogen titanate (H 2 Ti 3 O 7 ) structure with tubular morphology. These materials were characterized by X-ray diffraction, UV-Vis spectroscopy, N 2 physisorption, temperature programmed reduction, TEM, and FTIR spectroscopy. During the photocatalytic process, the ATL molecules were completely converted to amino-diol byproducts. It is the first time that these materials have been applied during the photocatalytic process in the degradation of pharmaceuticals products. The success of the silver nanoparticles (2 nm) consists of the homogeneous distribution over the surface of titanate nanotubes inhibiting the hole/electron recombination promoting the oxidation process. The Ag@H 2 Ti 3 O 7 with a concentration of silver as 1.0% shows the highest adsorption/degradation of ATL than the Ag@TiO 2 and the P25-Degussa. The great performance in the reuse test consists in the strong attachment of the silver nanoparticles on the titanium surface that inhibits the silver lixiviation during the photocatalytic tests.
