Based on these results it could be suggest that the phase forming during leaching process has a Al2O3 structure, where part of the Al atoms was replaced by Fe and Cu.
The ring diffraction pattern (Fig. 3b) obtained for the area presented in Fig. 3a correspond to structure of Fe3O4 spinel with space group of Fd-3m (a=0.839 nm).
The Fast Fourier transform FFT obtained from the area of the particle (Fig. 3d) confirms the structure of Fe3O4.
The oxide is enriched in Fe for the NaBH4 treated powder with the structure of Fe3O4 spinel, while the NaOH treated powder contained mainly Al with the structure close to Al2O3.

Introduction The occurrence and quantity of groundwater resource are affected by integrated factors, such as construction, lithologic character of stratas, structure, thickness, and so on.
These structures control the overall landscape of the research zone.
Fig.1 Faults, anticlines structure distribution in research area 1.3 General situation of hydrogeololgy The loosening stratas in study zone contain four series.
All the faults are high-angle thrust fault, thus Aquifer structure on both sides are changed, affecting the groundwater’s distribution.

Generally, the AuNPs displayed a spherical-like structure and dominantly separated each other.
In the NMP/Chi sample appeared a vibration at 1395 cm-1 that was assigned as CN stretching vibration in the chitosan structure.
This result also indicates that the NMP has a cubic-structured crystal.
The Fe3O4 crystal structures still exist and are similar to JCPDS #01-085-1436.
The resulting AuNPs were a spherical-like structure with an average of 14.99 nm particle size.

A Franklinite structure of these films turned out from XRD measurements.
Basic characterization of the films sprayed. a) XRD spectrum that illustrates both the polycrystalline structure of the films and the excellent matching with the franklinite reference. b) FTIR result, evidencing the absorption peaks of Fe-O and Zn-O bondings besides Si-O. c) Large area (80 x 80 µm 2) AFM image exhibiting a rough surface with ∼3 µm peaks protruding from the film surface. d) UV-Vis transmittance pattern as a function of photon energy.

It is hoped that the understanding of the transport processes thereby gained might ultimately be useful in the design and synthesis of nanochemical devices that can move small molecules and ions between sites within an artificial structure.
The two structures define the constituent rings of channels of differing rigidities.
A is the rigid channel of Fig. 1, while in B there are fewer inter-ring links and the conformational structure is looser.

Half a Century of Nanoantiferromagnetism: Richardson’s Phenomenon and Néel’s Models Marek Petrik1, a and Bernd Harbrecht1, b 1Department of Chemistry and Center of Materials Science, Philipps-Universität Marburg, Hans-Meerwein-Straße, 35032 Marburg, Germany apetrik@chemie.uni-marburg.de, bharbrecht@chemie.uni-marburg.de Keywords: Richardson, Néel, antiferromagnetism, nanoparticles, NiO.
The simple structure (distorted rock-salt type) and the strong exchange interaction (Néel temperature TN = 523 K) invite to a dedicated study of the spin dynamics in NiO nanoparticles over a wide temperature range.

Effect of crosslinker/monomer molar ratio on water content Water absorption of PAHG depends mainly on the content of hydrophilic groups contained in the structure of acrylamide and the crosslink degree of three-dimensional network of hydro-gel.

All aforementioned nanoobjects possess unique physical and chemical properties that differ from properties of bulk materials of the same chemical content and structure.
