Assisted by these developments emerges, concurrently, nanotechnology, an endeavor able to work at the molecular level, atom by atom, to create large structures with fundamentally new molecular organizations.
To be more specific, biomaterial surface features (such as surface, roughness, charge, chemistry, wettability, etc.) and the select properties of each protein will influence its adsorption characteristics and ultimately, will affect implant biocompatibility with host tissue.
Of course, if future research determines that free-floating nanoparticles are not safe inside the body, other techniques to create nanometer surface roughness will need to be utilized (such as anodization, chemical etching, photolithography, coating with nanometer self-assembled chemistries, etc. which are already showing promise towards increasing bone growth [29]).
This is a much easier route to exploiting the beneficial properties of nanostructured materials as nano biomedical implants than creating new chemistries that have not been, yet, recommended for inside-the-body use.

Ionic strength is a important parameter of cement pore solution chemistry which affects ion exchange reactions with solid phases[10].The result of calculation of the ionic strength at different time for each pore solution is shown in Fig. 3.

In such cases, any accurate models of erosion-corrosion must include an algorithm due to flow in addition to the mechanics and chemistry of the tribo-corrosion interactions.
A structured grid is performed in the near walls; for the bulk flow region, an unstructured grid was used.

For these reasons, in view of the green chemistry, reducing nitrophenols, a priority pollutant in the wastewater, to commercially important aminophenols is also very valuable.
This peak was characterized as the electronic transition n-π*, owing to the lone pair of electrons (oxygen and nitrogen atoms) in the DNP structure.

Preliminary Research on the Analysis of Chromium(III) Based on Digital Image Processing Method Utilizing Gold Nanoparticles as Colorimetric Sensor Pratyangga Surya Dyaninggara, Sri Juari Santosab*, Bambang Rusdiarsoc Department of Chemistry, Faculty of Mathematics and Natural Sciences, Universitas Gadjah Mada, Yogyakarta, Indonesia apratyangga.surya@mail.ugm.ac.id, b*sjuari@ugm.ac.id, cbrusdi_mipa@ugm.ac.id Keywords: Gold Nanoparticles, L-Ascorbic Acid, Chromium, Colorimetry, Digital Image Process.
The use of this method is also following the principles of Green Chemistry.
Among other methods, this method is selected because nanoparticle synthesis utilizing an ascorbic acid as a reducing agent can be done quickly and without heating treatment, which is more in line with green chemistry standards.
The reaction process in AuNPs synthesis using L-ascorbic acid as a reducing agent has been reported by Sun and his research group as shown in Eq. 1 [11]. 2 HAuCL4 + 3C6H8O6 2 Au0 + 3C6H6O6 + 8HCl (1) P-aminobenzoic acid was added to stabilize the AuNPs due to their structure.

According to International Union of Pure and Applied Chemistry (IUPAC), photocatalysts are defined as chemical reactions caused by light (photo-absorption) either ultraviolet, visible, or infrared by solid materials namely catalysts that have the ability to absorb photons and are generally owned by materials semiconductor material, the reaction on the semiconductor surface does not change during and after the reaction[7, 8].
The photocatalytic activity test was carried out in a closed container using a 300 W mercury lamp for 1 hour with sampling intervals every 10 minutes, then to get a decrease in concentration carried out by testing with a spectrophotometer at the Basic Chemistry Laboratory of Sultan Ageng Tirtayasa University.
To increase the crystallinity of the catalyst, calcination was carried out in the furnace at a temperature of 500oC to obtain the anatase crystal structure.

Several approaches have been used to separate the contributing effects and to explain their influence on the material properties based on relevant dimensions in rubber-silica interactions: primary particle (the scale 2-20 nm), the string of pearls structure (the scale 100-150 nm) or clusters created due to interparticle hydrogen bonding (the scale 10 3 -10 5nm) [6].
