Research ArticleOpen accessIn the keywordsReprocess of Copper from Worn Printed Circuit BoardsSwarnambiga A.K., M. Vidya Kalaivani, Sarah Sathyawathi, T.S. Ramyaa LakshmiThe objective of the study is to reuse printed circuit boards which are mainly made of copper. Most top down and bottom up approaches for the synthesis of Copper nanoparticles (CuNPs) needs pure copper (II) sulfate or any other copper salts as a raw material. For the expensive non-ecofriendly reasons, here we used wasted Printed Circuit Boards (PCBs) as an … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 12 Feb 2019 · 7,486 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynthesis and Characterization of Au@TiO2 NWs and their Catalytic Activity by Water Splitting: A Comparative Study with Degussa P25Abniel Machín, María Cotto, José Ducongé et al.Different amount of gold nanoparticles (1, 3, 5, 10 wt%) were deposited on the surface of synthesized titanium oxide nanowires (TiO2 NWs) and Degussa P25 (TiO2-P25). The results evidenced the presence of small and dispersed gold particles on the surface of TiO2 NWs and TiO2-P25 and an increase in the specific surface area of all the composites. The photocatalytic activity … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 6 Jun 2017 · 8,431 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAbout Nano Fusion and Dynamic FusionFlorian Ion T. Petrescu, John Kaiser CalautitHot fusion is currently a difficult goal to accomplish due to the high temperatures required, which are difficult to achieve and also to be maintained. For these reason, it is much easier to try to achieve cold fusion, or a combined method. In this paper, the author will briefly present some original relationships for setting up a theoretical model for … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 12 Mar 2016 · 11,311 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNatural Sensitizer for Dye-Sensitized Solar Cells Using Three Layers of Photoelectrode Thin Films with a Schottky BarrierHo Chang, Mu-Jung Kao, Tien-Li Chen et al.Problem statement: This study combines Au nanoparticles with TiO2 nanoparticles to form a Schottky barrier and applies it to the photoelectrode thin film of Dye-Sensitized Solar cells (DSSCs). Approach: First, commercial TiO2 powder (Degussa P25) was put into the alkaline solution to prepare TiO nanotubes (Tnt) by a hydrothermal process. Tnt were sintered at 550° to obtain TntC550 particles and … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 7,990 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Optical Nonlinearity of Au and Ag Nanoparticle Prepared by the γ-Radiation MethodEsmaeil Shahriari, W. M.M. Yunus, Kazem Naghavi, Elias SaionProblem statement: The third order nonlinear optical properties of metal nanoparticles have been of interest in physical chemistry, medical diagnostics and optical devices. Gold colloidal nanoparticles are responsible for the brilliant reds seen in stained glass windows and silver particles are typically yellow. The purpose of the study was to determine the nonlinear refraction and absorption coefficient of the Au … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 9,545 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynthesis and Characterization of Silver/Clay/Chitosan Bionanocomposites by UV-Irradiation MethodMansor Bin Ahmad, Kamyar Shameli, Majid Darroudi et al.Problem statement: Silver/Montmorillonite/Chitosan Bionanocomposites (Ag/MMT/Cts BNCs) have been synthesized by UV-irradiation reduction method in the absence of any reducing agent or heat treatment which is used to antibacterial application and medical devices. Approach: MMT, Chitosan and AgNO3 were used as a solid support, stabilizer and silver precursor, respectively. The properties of Ag/MMT/Cts BNCs were studied as a function of UV-irradiation … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,819 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynthesis and Characterization of Silver/Clay Nanocomposites by Chemical Reduction MethodMansor Bin Ahmad, Kamyar Shameli, Majid Darroudi et al.Problem statement: Silver Nanoparticles (Ag-NPs) have been synthesized by using chemical reduction method into the interlayer space of a Montmorillonite (MMT) as a solid support which is used to antibacterial application and polymer nanocomposites for fabrication of medical devices. Approach: AgNO3 and NaBH4 were used as a silver precursor and reducing agent, respectively. The properties of Ag/MMT nanocomposites were studied … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 8,175 accessesView PDFCite
Review ArticleOpen accessIn the keywordsMultidrug Resistant Microorganisms (MDR) and Biofilm Producers: A Challenge for Hospital Infectious ControlDaniel Lucio, Elizabeth Proaño, Alberto Bustillos et al.Antimicrobial Resistance (AMR) now represents a major threat to contemporary health care, especially in hospitals, where repeated antimicrobial exposure selects for and facilitates the dissemination of Multidrug-Resistant (MDR) microorganisms. Biofilm growth adds another layer of persistence by increasing microbial tolerance, supporting long-term colonization of medical devices, and worsening clinical and economic outcomes. This narrative review synthesizes evidence on MDR biofilm-forming … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 12 Sep 2026 · 791 accessesView PDFCite
