– We show detailed magnetic absorption spectroscopy results of an in situ cleaved high quality single crystal of magnetite. In addition the experimental setup was carefully optimized to reduce drift, self absorption, and offset phenomena as far as possible. In strong contradiction to recently published data, our observed orbital moments are nearly vanishing and the spin moments are quite close ...

Electron transfer from zerovalent iron (Fe0) to targeted contaminants is affected by initial Fe0 composition, the oxides formed during corrosion, and surrounding electrolytes. We previously observed enhanced metolachlor destruction by Fe0 when iron or aluminum salts were present in the aqueous matrix and Eh/pH conditions favored formation of green rusts. To understand these enhanced destruction...

Ethanol / Water Separation Technology is a long-term research. LTA molecular sieve, which an industrially important desiccant as kind of zeolite sieve. It always used in the reverse osmosis method, one seawater ddesalination, and extraction industrial ethanol method world. Membrane separation technology widely cell science, human microbial military industry, battery so on. With 2 years inventio...

The Zeolite Y as a support was modified by the incorporating of Fe and TiO2 in one single step using impregnation method. The synergistic effects between those components enhance the catalytic activity for the degradation of amaranth dye under ultrasonic irradiation with output power of 50 W and 40 kHz frequency. Different characterization techniques were used to elucidate the physical and chem...

The applicability of low-pressure membranes systems in distributed (point of use) water treatment is hindered by, among other things, their inability to remove potentially harmful viruses and ions via size exclusion. According to the USEPA and the Safe Drinking Water Act, drinking water treatment processes must be designed for 4-log virus removal. Batch experiments using magnetite nanoparticle ...

Hierarchical zeolites are regarded as promising catalysts due to their well-developed porosity, increased accessible surface area, and minimal diffusion constraints. Thus far, the focus has been on creation of mesopores in zeolites, however, little is known about a microporosity upgrading its effect catalytic performance. Here authors show that “birth” mesopore formation faujasite (FAU) type ze...

Zeolite faujasite (FAU), Linde type A (LTA) and FAU/LTA composite have been synthesized using tetramethylammonium cation (TMA+) as template, by adjusting only the concentration of Na+ ions in the initial solution (1.00 Al2O3 4.36 SiO2 : 2.39 (TMA)2 O : β Na2 O : 249.00H2 O). Na+ ions alter the phase composition of the product more than TMA+ or OH- ions. When Na2 O concentration [Na2 O] increase...

Multifunctional nanomaterials showed graet advantages in drug delivery. Folic acid (FA) binding protein, a glycosyl phosphatidyl inositol anchored cell surface receptor for folate, is overexpressed in several human tumors, whereas it is highly restricted in normal tissues. Therefore, in this study, FA, polyethylene glycol (PEG), and Fe3O4 nanoparticles multifunctionalized short multiwall carbon...

We report a facile method to produce a magnetically separable graphene oxide–magnetite nanocomposite (GO–Fe3O4) and its adsorption performance in methylene blue (MB) removal from aqueous solution. The GO–Fe3O4 nanocomposite was synthesized by a solution-phase self-assembly method including the incorporation of monodisperse Fe3O4 nanoparticles (NPs) and GO in a dimethylformamide/chloroform mixtu...

We report on the fabrication of thin coatings based on polylactic acid-chitosan-magnetite-eugenol (PLA-CS-Fe3O4@EUG) nanospheres by matrix assisted pulsed laser evaporation (MAPLE). Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) investigation proved that the homogenous Fe3O4@EUG nanoparticles have an average diameter of about 7 nm, while the PLA-CS-Fe3O4@EUG nanos...
