Self-Assembled Monolayers of Alkanesulfonic and -phosphonic Acids on Amorphous Iron Oxide Nanoparticles

TL;DR: In this article, a functionalized amorphous Fe2O3 nanoparticles with alkanesulfonic and octadecanephosphonic acids was analyzed and it was suggested that free Fe−OH groups can serve as proton donors to assist in the sulfonic acid desorption process and that because of the diprotic nature of the phosphonic acid these free surface Fe−H groups may no longer be available.
Journal ArticleDOI
High velocity interparticle collisions driven by ultrasound.
TL;DR: A simple kinematic model of the ultrasound-driven interparticle fusion predicts a melting criterion that is nonmonotonically dependent on particle size and is shown to be in agreement with experiment.
Journal ArticleDOI
A Cultured Greigite-Producing Magnetotactic Bacterium in a Novel Group of Sulfate-Reducing Bacteria
Christopher T. Lefèvre,Christopher T. Lefèvre,Christopher T. Lefèvre,Nicholas Menguy,Fernanda Abreu,Ulysses Lins,Mihály Pósfai,Tanya Prozorov,David Pignol,David Pignol,David Pignol,Richard B. Frankel,Dennis A. Bazylinski +12 more
TL;DR: Genomic analysis of strain BW-1 reveals the presence of two different magnetosome gene clusters, suggesting that one may be responsible for greigite biomineralization and the other for magnetite, a previously unknown group of sulfate-reducing bacteria in the Deltaproteobacteria.
Journal ArticleDOI
Protein-Mediated Synthesis of Uniform Superparamagnetic Magnetite Nanocrystals**
Tanya Prozorov,Surya K. Mallapragada,Balaji Narasimhan,Lijun Wang,Pierre E. Palo,Marit Nilsen-Hamilton,Timothy J. Williams,Dennis A. Bazylinski,Ruslan Prozorov,Paul C. Canfield +9 more
TL;DR: Magnetite nanocrystals are synthesized in the presence of a recombinant Mms6 protein thought to be involved in the biomineralization of bacterial magnetite magnetosomes, the mammalian iron-storage protein, ferritin, and two proteins not known to bind iron, lipocalin (Lcn2) and bovine serum albumin (BSA) as mentioned in this paper.
Journal ArticleDOI
Sonochemistry and Sonoluminescence of Room-Temperature Ionic Liquids
TL;DR: Multibubble sonoluminescence spectra and headgas analysis reveal a variety of decomposition products from the sonolysis of N,N'-dialkylimidazolium ionic liquids.
