Solution Grown Nanostructured Ceramic Coatings for Photocatalytic and Antibacterial Surface

Tao T., Cho J., Binghamton University, US

Ceramics coatings have received great attention for use as a functional surface, as well as a protective and barrier coating. We report a low-temperature hydrothermal processing of nanostructured ceramic coatings that enable their surface to [...]

Formulation, characterization and applications of titanium dioxide, polyoxometalates and silver nanocomposites

Kumar Daima H., Amity University Rajasthan, IN

In the recent past, Titanium dioxide (TiO2), polyoxometalates (POMs) and silver (Ag) based nanomaterials have been employed for various biological and industrial applications. TiO2 possesses excellent photocatalytic activity; POMs are keggin ions with exceptional biomedical [...]

Bio-inspired Polydopamine Treatment and Nanosilver Formation for Antibacterial Uses

Chiu Y.-H., Li M.-C., Wu K.-M., Chung Y-C, National University of Kaohsiung, TW

In the study, we employed the mussels’ glue component—dopamine and its excellent reducing ability toward silver ions, to create a novel antibacterial effect on a facial mask surface so as not to add harmful antiseptics [...]

Synthesis and Characterisation of Nano-Sized Triphenylphosphine Capped bis(4-methylpiperazine-1-carbodithioato) zinc(ll)

Kalia S.B., Sharma M., Himachal Pradesh University, Shimla, IN

Present study involves the synthesis of and studies on a nanosized coordinate complex of 4-methylpiperazine-1-carbodithioate (4-MPipzcdt) ligand with zinc(II), i.e. Zn(4-MPipzcdt)2, using triphenylphosphine (PPh3) as capping agent. TEM study revealed nanosized particles with size range [...]

Characterization of silver-coated carbon nanotubes dispersed in a specifically formulated dispersant – NanoSperse AQ®

Chaudhari A.A., Singh S.R., Pillai S.R., Alabama State University, US

Silver-coated carbon nanotubes (AgCNTs) are well documented for their antibacterial properties. However, aqueous dispersions of AgCNTs could be less effective against bacteria due to their tendency to agglomerate when re-suspended in water. In this study [...]

Antibacterial activity on Polyamide and Natural fabrics using Low Temperature Plasma

Shahidi S., Rashidi A., Wiener J., Ghoranneviss M., I.A. University, IR

Polyamide (PA) synthetic textiles are among the most used fibers in the biomedical textile field [1]. Wounds often provide a favorable environment for the colonization of microorganisms. In order to improve the opportunity for wound [...]

Antibacterial activity of flame-made Ag/SiO2 nanoparticles

Sotiriou G.A., Camenzind A., Meyer A., Panke S., Pratsinis S.E., ETH Zürich, CH

The synthesis of flame made Ag/SiO2 nanoparticles was achieved by flame spray pyrolysis. The precursor selection influence on the final product was studied. The produced powders were characterized by TEM/STEM, XRD, BET, UV/vis. Additionally, the [...]

Evaluation of Antibacterial Activities of Zinc Oxide-Titanium Dioxide Nanocomposites Prepared by Sol-Gel Method

Chang H., Leung H., Nanyang Polytechnic, SG

Antibacterial activity of ceramic powders has attracted attention as a new technique that can substitute for conventional methods using organic agents. Ceramic powders of zinc oxide (ZnO), calcium oxide (CaO) and magnesium oxide (MgO) were [...]

Silver nanoparticles synthesized on titanium dioxide fine particles

Niño-Martínez N., Martínez-Castañón G.A., González-Hernadez J., Ruiz F., Universidad Autonoma de San Luis Potosi, MX

Silver nanoparticles with a narrow size distribution (20 nm mean size) were synthesized over the surface of two different commercial TiO2 particles using a simple aqueous reduction method. The reducing agent used was NaBH4; different [...]
