The fractal dimensions of the pore structures of low permeability oil reservoirs are less than 2.
Fractal geometry has been applied in the fields of geology and chemistry.
In the field of chemistry, the activity of a molecule depends on whether its fractal dimension matches the fractal dimension of the target [6].

In common, carbon nanofibers (CNFs) observed in the early 1980s are prepared by a catalytic method, and CNFs have been recognized as one of very attractive materials due to their nano-structure and particular properties.
Total pore volume was estimated to be the liquid volume of the nitrogen at a relative pressure of about 0.995, and the micropore structures were analyzed by using D-R equations [10].
This result probably means that porous CNFs have various pore structures including high amount of micro- and mesopores.

Introduction The term SiAlON was originally coined to describe materials containing Si, Al, O and N (and other metals), of very wide compositions and crystal structures [1].
Crystal structure of α-Sialons requires an extra cation for stability.
Some larger cations can enter the structure only in combination with other cations.
Improvement of Sialon properties has been obtained by optimization of the chemistry and microstructure.
Improvement of fracture toughness is possible by the microstructure control, when usually equiaxed morphology of grains is changed by proper chemistry to the elongated one [9].

The structure/function relationship for them was discussed.
The study on structure/reactivity relationship of the active sites in oxidoreductases, such as soluble methane monooxygenase (sMMO) and ribonucleotide reductase (RNR) with high-valent Fe2(µ-O)2 species as intermediates in enzymatic reactions, have attracted much attention also from the point of view of organic, catalytic and industrial chemistries [1-4].

Introduction Searching for new antimycobacterial compounds is one of the most challenging tasks in current medicinal chemistry.
Chemistry The synthetic route of N-(pyridin-4-yl) salicylamides was depicted in Fig. 1 N-(pyridin-4-yl) salicylamides 1a-6h were prepared by treatment of the corresponding substituted acetylsalicyloyl chlorides with substituted 4-amino-pyridines in chloroform in the presence of triethylamine.
The structures were fully identified by 1H NMR, 13C NMR and IR spectra.
With respecting to the activities against M. tuberculosis (TB), there are two additional major aspects considered: innate resistance, the unique structure and composition of the highly hydrophobic cell wall that must be traversed.
However, being based on our research, the activities were affected by not only hydrophobicity but also structure and electronic requirements.
