Study of Bacterial Cell Colonization on Plasma Induced Bio‐Adoptable Polymer Nanocomposites Membranes

25-Nov-2015 | Narendra Kumar Agrawal, Ravi Agarwal, Gautam Aashish Kumar, Jeevanshu Jain, Yogesh Kumar Vijay, Kanti Chand Swami, Macromolecular Symposia, 2015

Summary Polymers are receiving great interest for synthesis of biomedical devices but to use them for any biomedical application they must show biocompatibility. In this work we have enhanced bio‐compatibility of Poly (methyl methacrylate) (PMMA) using TiO2 nanoparticles (NPs) and plasma ...


Structural and Morphological Study of PS‐ZnO Nanocomposite Membrane

25-Nov-2015 | Lokesh Kumar Jangir, Yogita Kumari, Anil Kumar, Manoj Kumar, Kamlendra Awasthi, Macromolecular Symposia, 2015

Summary Zinc Oxide (ZnO) nanoparticles were synthesized by chemical precipitation method. Particle size as calculated from X‐ray Diffraction (XRD) and Transmission Electron Microscopy (TEM) were found to be 18 ± 2 nm. Polystyrene (PS)‐ZnO nanocomposite membrane of thickness 30 μm were ...


Structural and Morphological Study of PS‐TiO2 Nanocomposite Membranes

25-Nov-2015 | Yogita Kumari, Lokesh Kumar Jangir, Anil Kumar, Manoj Kumar, K. C. Swami, Kamlendra Awasthi, Macromolecular Symposia, 2015

Summary Anatase titanium dioxide (TiO2) nanoparticles (NPs) were synthesized by sol‐gel method. The phase formation and size of NPs were characterized by Transmission electron microscopy (TEM) and X‐ray diffraction (XRD) and average diameter of nanoparticles found to be (17 ± 2) nm. Further, ...


One pot synthesis of environmentally friendly lignin nanoparticles with compressed liquid carbon dioxide as an antisolvent

25-Nov-2015 | Aye Aye Myint; Hun Wook Lee; Bumjoon Seo; Won-Su Son; Junho Yoon; Tae Jun Yoon; Hee Jeong Park; Jihyun Yu; Jeyong Yo ..., Green Chemistry, 2015

Nanoparticles from the commercial kraft lignin were developed using a facile, one pot green technology of compressed CO2 antisolvent. N,N,-dimethylformamide (DMF) was employed as an organic solvent to prepare the lignin solution. The effects of various process parameters: temperature, pressure, ...


Use of Tethered Enzymes as a Platform Technology for Rapid Analyte Detection

25-Nov-2015 | Roy Cohen et al., PLoS ONE, 2015

by Roy Cohen, James P. Lata, Yurim Lee, Jean C. Cruz Hernández, Nozomi Nishimura, Chris B. Schaffer, Chinatsu Mukai, Jacquelyn L. Nelson, Sharon A. Brangman, Yash Agrawal, Alexander J. Travis Background Rapid diagnosis for time-sensitive illnesses such as stroke, cardiac arrest, and septic ...


Multilayer photoactive nanocolloidal PPy:PSS as a novel substitute for Pt free counter electrode in DSSC

24-Nov-2015 | S. Maruthamuthu, J. Chandrasekaran, D. Manoharan, S.N. Karthick, Hee‐Je Kim, Journal of Applied Polymer Science, 2015

ABSTRACT Water dispersible and highly processable, Polypyrrole (PPy) nanocolloidal particles were synthesized by chemical oxidation polymerization with 15 wt % of anionic polyelectrolyte poly (styrene sulfonate) (PSS) at 5°C has been reported in this work. This polymer composite (PPy:PSS) was ...


Electrochemical Insight into the Brust–Schiffrin Synthesis of Au Nanoparticles

24-Nov-2015 | Akihiro Uehara; Samuel G. Booth; Sin Yuen Chang; Sven L. M. Schroeder; Takahito Imai; Teruo Hashimoto; J. Frederick ..., Journal of the American Chemical Society, 2015

The mechanism of the Brust–Schiffrin gold nanoparticle synthesis has been investigated through the use of ion transfer voltammetry at the water/1,2-dichloroethane (DCE) solution interface, combined with X-ray absorption fine structure (XAFS) of the reaction between [AuCl4]− and thiol (RSH) in ...

Hollow ZSM‐5 with Silicon‐Rich Surface, Double Shells, and Functionalized Interior with Metallic Nanoparticles and Carbon Nanotubes

20-Nov-2015 | Chengyi Dai, Anfeng Zhang, Min Liu, Xinwen Guo, Chunshan Song, Advanced Functional Materials, 2015

Hollow ZSM‐5 single crystals with silicon‐rich exterior surface are prepared by a “dissolution–recrystallization” strategy in tetrapropylammonium hydroxide solution. Selective dissolution and exterior recrystallization cause the silicon components to migrate from the inside to outside, resulting ...


Quantifying “Softness” of Organic Coatings on Gold Nanoparticles Using Correlated Small-Angle X-ray and Neutron Scattering

20-Nov-2015 | Benjamin T. Diroll; Katie M. Weigandt; Davit Jishkariani; Matteo Cargnello; Ryan J. Murphy; Lawrence A. Hough; Chris ..., Nano Letters, 2015

Small-angle X-ray and neutron scattering provide powerful tools to selectively characterize the inorganic and organic components of hybrid nanomaterials. Using hydrophobic gold nanoparticles coated with several commercial and dendritic thiols, the size of the organic layer on the gold particles ...
