Zeolites are crystalline microporous aluminosilicate materials with a regular three dimensional pore structure, which is relatively stable at high temperatures (Figure 1-(A)).
These membranes are produced by sol-gel technique and their structure generally consists of three-layer system, i.e. support, intermediate layer and molecular sieve top layer.
Carbon hollow fibre membranes, having an asymmetric structure, showed a large permeability and a high selectivity for some gases and light hydrocarbons.
It was demonstrated that with this new technique it is possible to optimize the hollow fibre support structure with respect to the morphology, mechanical strength and pore size distribution.

Furthermore surface chemistry and topology are both important factors with regard to the biocompatibility and performance of tissue engineering scaffolds.
Large, homogeneous open pores were visible on the top surface of the CS/PLLA scaffolds and a network structure appeared in the large pores.
PLLA film showed a highly regular hexagonal arrangement of pores (honeycomb-patterned structure) and a well-interconnected, uniform pore structure, wherein PLLA formed a 3D patterned surface in the pores of the CS scaffolds.
So this 3D surface pattering porous structure provided new ideas for the future tissue engineering scaffolds.
Structure and characteristic of chitosan Bombyx mori silk fibroin blend films.

Less than half a century ago just an idea of presence of free alkalis in a ceramic matrix was considered by ordinary Portland cement people as an absurd one and this was a basic postulate accepted in chemistry of cements.
And what expressed the scientists who observed ancient structure greatly was a great difference in quality between restored and original parts of structures.
Being formed predominantly in a pore space, they fill it and promote strong crystallization contacts with the primary phases, as well as initiate formation of more homogeneous and dense structure.
High performance properties of the alkali-activated cement matrix can be attributed not only to its more perfect phase composition of its hydration products but more perfect parameters of its structure (Figure 2).

Introduction Nanoparticles are nanosized structures in which at least one of its phases has one or more dimensions (length, width or thickness) in nanometer range i.e. 1-100nm.
Top-down approach involves making smaller and smaller structures or particles through etching from the bulk material while bottom-up approach involves building up nanoscale structures from atoms and molecules [7].
The biggest problem with the top-down approach is the imperfection of surface structure and significant crystallographic damage to the processed patterns, and therefore bottom up approach is preferred.
Conclusion The use of Eucalyptus corymbia leaf extract offers a simple synthetic protocol devoid of toxic chemicals either as reducing, stabilizing or capping agents in line with green chemistry principles.

However, the complete extraction of lignocellulosic structure in EFB is complex and difficult to achieve.
Lignin is the third most abundant organic compound in the lignocellulosic structure.
In addition, lignin bonds with highly branched polymeric structures will further stabilizes the lignocellulosic structure.
Lignocellulosic structure of biomass can be qualitatively identified from thermogravimetric analysis.

This is because the energy added to temperature rise within the sample and the energy within the hydration system rises; therefore, the total energy may increase the degree of irregularity of the C–S–H structure [15,16].

Introduction Studying the local chemistry and the physical structure of materials into the SEM by means of CL assessments is a well established procedure, CL spectra being useful in providing information on point and planar defects (e.g., precipitates, inclusions and grain-boundaries), variations in impurity concentration, states in the energy gap and excess carrier diffusion lengths [1].
In considering CL as a fully quantitative spectroscopy tool, we have recently emphasized that a CL spectrum, in addition to traditionally studied features related to chemistry and crystallographic structure of materials, also contains information about the stress state in the material through the local wavelength variation of selected bands, this phenomenon being referred to as the piezo-spectroscopic (PS) effect.
In standardized fabrication and packaging procedures, residual stress fields cannot easily be avoided, especially in complicated structures comprised of many diverse materials.
At low temperature, three main lines are observed at wavelengths of 357.2 and 357.0 nm (from D 0XA transition), in the wavelength range between 360.42-358.34 nm a rich TES structure is observed, and additional lines in the interval 356.79-354.24 nm arise from D 0XB, D 0XCn=1 and D0X n=2 transitions.
