Basic Structure of TiO2
The inner structure of material determines the nature and performance of that material.
Rutile is the stablest structure of TiO2.
Light-catalyzed reaction is composed of a series of complex process of surface chemistry and surface-physics adsorption-desorption.
The development of DFT widens its application field such as physics, chemistry, biology, etc.

These numerical simulations are aimed to study the flow structure, supersonic mixing and combustion for cavity based injection.
The shock structure and combustion phenomenon are not only affected by the geometry but also by the flight Mach number and the trajectory.
Kumaran and Babu [8] worked on “Investigation of the effect of chemistry models on the numerical predictions of the supersonic combustion of Hydrogen,” and it has been found that the multi step chemistry predicts higher and wider spread heat release than what is predicted by single step chemistry.
Single step, finite rate kinetics have been used to model chemistry.

Topography plays a major role on surface-cell interaction beside the surface chemistry.
Even though various research works show improved cell adhesion and proliferation on modified polymer surfaces or stainless steel [7] , treatment of such surfaces leads to a change in the surface chemistry and to an alteration of topography and roughness [8,9].
In such cases, it is difficult to differentiate the effect of topography regardless from the surface chemistry on the cell-surface interaction.
The chaotic morphology reminds of a “spaghetti-like” structure.
This structure is composed of NWs of 20 nm diameter and several micrometers of length.

Effect of Solution Chemistry and Electroplating Conditions on the
Deposition Rate and Wear Resistance of Eco-friendly Trivalent
Chromium Layers
Min Young Choi1,a, Y.
Hence, the objectives of this work are to study the effect of solution chemistry on the deposition behavior and to find an optimum plating condition preparing for industrially applicable and hard trivalent chromium layers.
Emphasis is especially paid on the effect of solution chemistry, plating voltage and wear properties of the thick trivalent chromium layers.
The solution chemistry is based on chromium chloride or chromium sulfate containing various positive ions such as NH4+ and K +, respectively.
As shown in Fig. 4, the chromium layer is fine crystalline structure without any precipitates.

Structures of ZnAHN (R=H) and ZnVHN (R=CH3).
There was no significant change in the low wavelength region (except for slight change around 350-410 nm for Lysozyme + ZnAHN) reflecting the change of secondary structure, suggesting that the association of the zinc(II) complexes has little effect on the three-dimensional structure of lysozyme, in contrast to human serum albumin [11].
When the same zinc(II) complexes are docked with human serum albumin, it differs in that the secondary structure change of the protein is disturbed significantly.
