It is a mononuclear discrete structure.
With three free water molecules, the present structure has a network of hydrogen bonds.
Similar structures with the same ligand have appeared in the literature [9,10].
The crystal structure of the title compound Fig.2.

Preface This special topic volume 'Advances in Electronic Materials' covers different fields of materials such as silicon, silicon-germanium hetero-structures, high-k materials, III-V semiconductor alloys and organic materials as well as nano-structures for spintronics and photovoltaics.
Progress in classical scientific fields such as physics, biology, chemistry, mechanics and software are often based on new developments within the area of electronic materials.
New hetero-structure device concepts will be the basis for further improvements in micro- and optoelectronics and are described in detail in the subsequent chapter.

Quite often, the matching of the mechanical properties is the major consideration, and therefore the weld-metal chemistry may vary to some reasonable extent from the base-metal chemistry.
The structure also contains in certain locations some of the quantities of upper and lower bainite.
The structure is such which renders the material with low ductility and poor toughness.
The ferrite grains are usually fine and the structure mainly comprises of ferrite, pearlite and carbide.
The structure also shows the presence of small quantities of retained austenite.

The periodic structure of GNPs on flat gold surface has large impact for plasmonic sensing applications.
A finger print signal was observed at 2850.65, 2867.99, 2930.97 cm-1, which is an indication of self assembled structures and capping around GNPs (Fig.6).
On the surface of the GNPs, a self assembly structure was observed and the phenolic groups in the extract cause this self-assembly.

For biosensorics, photonics, chemistry, etc. there is a need for nanoelements supporting strong plasmonic response over a wide spectral range.
In addition, the superbroadband plasmon-mediated enhancement is confirmed by numerical calculations of the electromagnetic near-fields as well as by substantially enhanced photoluminescence from the Rhodamine 6G (R6G) and the lanthanide-based (Eu:TTA) emitters capping the bimetallic structures.
For the production of large arrays of structures, the sample was arranged on PC-controlled micropositioning platform and scanned with a laser beam with a 1 kHz repetition rate.
Even more pronounced nanotexture can be obtained by using the magnetron deposition of the thin metal film above the laser-printed spallative structures as it is illustrated by the series of the highly magnified SEM images (Fig.1(b e)).
Finally, the possibility of using such structures for SEPL was demonstrated by enhancing the photoluminescence of R6G and Eu:TTA dyes.

We aimed to investigate the morphology and structure change of 75% ethanol vapor-induced silk fibroin nanofibers.
In this study, we aimed to investigate 75% ethanol vapor-induced morphology and structure change of SF nanofibers.
The fine structure on the surface of nanofibers had been quantified using AFM.
However, after inducement of 75% ethanol vapor, the SF nanofibrous membranes took silk II structure.

EuCo2X2 crystallize in the ThCr2Si2 structure (space group I4/mmm) [1, 2] and EuM5 crystallize in the CaCu5 structure (space group P6/mmm) [3, 4].
However, band structure calculations with the LAPW method [9] showed that Eu is mixed valent (v~2.5) in EuCo2X2 [10].
Theoretical XPS valence band spectra were calculated from our band structure results.
