These properties are highly dependent on size, structure, morphology and accordingly on their mechanism of synthesis [1].
This modification allows controlling the properties of the synthesized nanostructured cobalt, such as composition, structure, morphology, and magnetic properties.

The high impact collisions that reduce the microcrystalline materials down to nanocrystalline structure, don’t affect chemically the composition of the fly-ash [15].
Nano-cement particles In order to increase the cement behaviour by decreasing the size of its particles down to nano-scaled dimensions, several approaches are possible [27, 28]: § top-down method that consists in a high energy milling of Portland cement particles, § bottom-up method that is a chemical synthesis of nano-particles, § the nano-binder method that involves an inter-grinding of cement with dry mineral additives in the ball mill [29], § the use as admixtures to cement of nano-clay particles (~1nm size), obtained by exfoliating the base structure of clays that is formed by crystalline layers of aluminium phyllosilicates [30].
A great advantage of this software concept is the logical structure and the „self-learning” ability, all this presented in a simple but precise manner.
Another advantage is the „web-free-acces” posibility, that offers the oportunity to bring togheter researchers from the concrete domain, materials science, chemistry, physics and other researches domains with interest in the nano-materials field.

Introduction The utilization of mineral admixtures, particularly fly ash (FA), in concrete structures has noticeably increased due to the increase in environmental awareness.
Numerous concrete structures and concrete pavements could be exposed to very cold weather and freezing conditions during their life cycle.
Structures made with FA concrete are no exception.
The cement chemistry and the hydration process controlling the rapid strength development have been the topic of several scientific studies [14, 19].

The advantages of lightweight concrete include a reduction in cost, a reduction in handling and production time, and an improvement in the thermal insulation performance of concrete structures[13].
LDPE belongs to the type of polymers that have a branched structure.
This indicates that the granules tested are polymers with a linear structure, as the wave number regions at 1469 cm-1 and 719 cm-1 are not branched.
On the basis of these two peaks and according to the reference of Rajandas et al. it is confirmed that the structure is consistent with LDPE and LLDPE [16,17].

Antibacterial Activity Edible Coating of Jackfruit Seed Starch and Alginate Incorporated with ZnO Nanoparticles Applied to Cherry Tomatoes Lina Mahardiani1,a* and Nila Riyaz Saputri1,b 1Department of Chemistry Education, Faculty of Teacher Training and Education, Universitas Sebelas Maret, Surakarta, Indonesia.
The advantages of alginate as a basic ingredient for edible coatings are safe for consumption, has a unique colloidal structure, stabilizer, binder, suspending agent, gelling agent, and emulsion stability [8].
This is the main characteristic of the starch structure of jackfruit seeds.
There is a difference in the diameter of the resulting inhibition zone due to differences in the structure of the cell wall between the two bacteria.
S. aureus bacteria have a cell wall structure with low lipid content which is more easily penetrated by antibacterial compounds than E. coli bacteria which have a more complex wall structure.

Herewith, the literature data state high toxicity of nanosized aluminum particles (depression of pulmonary function, inflammation of the respiratory tract [16], neuronal cell death [17], distortion of the structure of blood vessels [18] and damage to the structure of the brain [19, 20]).
Product drying in the air does not provide their full dehydration, and gibbsite phase formation aligns with the investigation data [34], according to which low heating of “nanoaluminum-water” system may give rise to porous oxide/hydroxide structures, where aluminum hydroxide of the described morphology is formed.
Though, it can be suggested that the gibbsite formed may have an amorphous structure which requires further investigation.

Introduction The catalytic activity and selectivity of metal supported catalysts are well known to depend strongly upon the dispersion, loading and the local structure of metal additives.
The crystalline structure was examined by X-ray diffraction using a Bruker (Siemens) D5005 apparatus.
The differences in surface area can easily be related to the BN structure.
The hexagonal BN crystallographic structure consists of three BN groups stacked into a hexagonal framework leading to BN layers as described for graphite.

These localized states form not only as a result of interface chemical bonding but also due to the formation of new local structures/polytypes.
Rather this corresponds to a new local structure/polytype with a larger band gap.
Depth-resolved LEEN spectra of oxides on SiC reveal additional states that depend sensitively on the local interface chemistry.
The lowest thickness is most common and corresponds to a single stacking fault in the 4H-SiC lattice structure.
