Presence of Nanoparticles in Wash Water from Conventional Silver and Nano-silver Textiles

26-06-2014 | Denise M. Mitrano; Elisa Rimmele; Adrian Wichser; Rolf Erni; Murray Height; Bernd Nowack, ACS Nano, 2014

Questions about how to regulate nanoenhanced products regularly arise as researchers determine possible nanoparticle transformation(s). Focusing concern on the incorporation and subsequent release of nano-Ag in fabrics often overshadows the fact that many “conventional silver” antimicrobials such ...

Design and Fabrication of Regenerable Polyelectrolyte Multilayers for Applications in Foulant Removal

24-06-2014 | Joseba Irigoyen, Nikolaos Politakos, Richard Murray, Sergio E. Moya, Macromolecular Chemistry and Physics, 2014

Regenerable polyelectrolyte multilayers (PEMs) are prepared on the basis of a sacrificial block of polyelectrolyte on the top of a non‐removable PEM. Poly(allylamine hydrochloride) (PAH) and polyestyrene sulfonate (PSS) PEMs with a block of poly(diallylmethylammonium chlor­ide) (PDADMAC)/PSS on ...

Bulk Metallic Glass-like Scattering Signal in Small Metallic Nanoparticles

09-06-2014 | Vicky V. T. Doan-Nguyen; Simon A. J. Kimber; Diego Pontoni; Danielle Reifsnyder Hickey; Benjamin T. Diroll; Xiaohao ..., ACS Nano, 2014

The atomic structure of Ni–Pd nanoparticles has been studied using atomic pair distribution function (PDF) analysis of X-ray total scattering data and with transmission electron microscopy (TEM). Larger nanoparticles have PDFs corresponding to the bulk face-centered cubic packing. However, the ...

Substituent Effects on Spin State in a Series of Mononuclear Manganese(III) Complexes with Hexadentate Schiff-Base Ligands

05-06-2014 | Brendan Gildea; Michelle M. Harris; Laurence C. Gavin; Caroline A. Murray; Yannick Ortin; Helge Müller-Bunz; Charles ..., Inorganic Chemistry, 2014

Eleven new mononuclear manganese(III) complexes prepared from two hexadentate ligands, L1 and L2, with different degrees of steric bulk in the substituents are reported. L1 and L2 are Schiff bases resulting from condensation of N,N′-bis(3-aminopropyl)ethylenediamine with ...

Graphene Oxide Attenuates Th2-Type Immune Responses, but Augments Airway Remodeling and Hyperresponsiveness in a Murine Model of Asthma

23-05-2014 | Michael R. Shurin; Naveena Yanamala; Elena R. Kisin; Alexey V. Tkach; Galina V. Shurin; Ashley R. Murray; Howard D. ..., ACS Nano, 2014

Several lines of evidence indicate that exposure to nanoparticles (NPs) is able to modify airway immune responses, thus facilitating the development of respiratory diseases. Graphene oxide (GO) is a promising carbonaceous nanomaterial with unique physicochemical properties, envisioned for a ...

Improved Model to Predict the Free Energy Contribution of Trinucleotide Bulges to RNA Duplex Stability

22-05-2014 | Meghan H. Murray; Jessicah A. Hard; Brent M. Znosko, Biochemistry, 2014

Trinucleotide bulges in RNA commonly occur in nature. Yet, little data exists concerning the thermodynamic parameters of this motif. Algorithms that predict RNA secondary structure from sequence currently attribute a constant free energy value of 3.2 kcal/mol to all trinucleotide bulges, ...

Altered global brain signal in schizophrenia [Psychological and Cognitive Sciences]

20-05-2014 | Genevieve J. Yang; John D. Murray; Grega Repovs; Michael W. Cole; Aleksandar Savic; Matthew F. Glasser; Christopher ..., Proceedings of the National Academy of Sciences current issue, 2014

Neuropsychiatric conditions like schizophrenia display a complex neurobiology, which has long been associated with distributed brain dysfunction. However, no investigation has tested whether schizophrenia shows alterations in global brain signal (GS), a signal derived from functional MRI and ...

High-Temperature Photoluminescence of CdSe/CdS Core/Shell Nanoheterostructures

15-05-2014 | Benjamin T. Diroll; Christopher B. Murray, ACS Nano, 2014

The steady-state and time-resolved photoluminescence properties of CdSe/CdS heterostructures are studied as a function of temperature from 300 to 600 K. The emission properties of samples are found to behave similarly to bulk CdSe, with the samples maintaining high color purity and a slightly ...
