“…[28][29][30][31][32][33][34][35][36][37][38] For synthesis of nanostructures, formic acid has been suggested to promote anisotropic formation of Pt deposits, since anisotropic deposits were not obtained using other reducing agents. 38 In some colloidal systems, a delicate interplay exists between the complexed metal ion, reducing agent, and organic additives by which the shape of nanostructures can be controlled.…”

We report room temperature deposition of compact Si films onto 6061 Al alloy from aqueous solutions containing 10 mM HF and 20 mM Na 2 SiF 6 in 80 wt % formic acid (HCO 2 H) by a combination of galvanic and electroless deposition. Deposition for 30 h. yields a 7-10 m thick, dark grey Si thin film that does not change color upon exposure to air. Elemental analysis demonstrates that the as-deposited film contains 2-3 atom % Al, 4-5 atom % Cu, and 92-94 atom % Si. We believe that this is the first report of aqueous, room temperature deposition of thick, compact Si films.

“…The study indicates that the microcrystalline chitosan was used as reducing agent and stabilizer to synthesize the AgNPs at room temperature. Using a noniogenic polymer (PEO), a natural polymer (N-carboxyethylchitosan), and silver nanoparticles, Penchev et al [87] observed a complete killing of the bacteria (Staphylococcus aureus) within an hour of contact at higher concentrations of silver nanoparticles, whereas at low concentrations the nanoparticles only inhibits bacterial growth. They used a one pot system to fabricate the nanofibre in which all the components were added into the spinning solution.…”

Abstract. Over the past decades, electrospinning of biopolymers down to nanoscale garnered much interest to address most of the millennia issues related to water treatment. The fabrication of these nanostructured membranes added a new dimension to the current nanotechnologies where a wide range of materials can be processed to their nanosize. Electrospinning is a simple and versatile technique to fabricate unique nanostructured membranes with fascinating properties for a wide spectrum of applications such as filtration and others. These nanostructured membranes, fabricated by electrospinning, were found to be of a paramount importance because of their advanced inherited properties such as large surface-to-volume ratio, as well as tuneable porosity, stability, and high permeability. The extensive research conducted on these materials extended the success of electrospinning not only to bio-based polymer nanofibres, but to their hybrids and their derivatives. The technique also created avenues for advanced and massive production of nanofibres. This paper reviews the recent developments in the electrospinning technique. Electrospinning of biopolymers, their blends and functionalization using metals/metal oxides, and the potential applications of electrospun nanofibrous membranes in water filtration are discussed.

“…An original approach for preparation of water‐insoluble hybrid nanofibrous materials from chitosan or CECh and AgNPs by electrospinning has been proposed . The ability of concentrated formic acid to dissolve chitosan and CECh and to reduce Ag + to AgNPs, thus making the in situ synthesis of AgNPs possible, has been used.…”

Chitosan is non-toxic, biocompatible, and biodegradable polysaccharide from renewable resources, known to have inherent antibacterial activity, which is mainly due to its polycationic nature. The combining of all assets of chitosan and its derivatives with the unique properties of electrospun nanofibrous materials is a powerful strategy to prepare new materials that can find variety of biomedical applications. In this article the most recent studies on different approaches for preparation of antibacterial fibrous materials from chitosan and its derivatives such as electrospinning, coating, and electrospinning-electrospraying, loading of drugs or bioactive nanoparticles are summarized.
