Binding Peptide

A facile method to prepare a hydrophilic/hydrophobic metal surface by metal-binding peptide was proposed in this article. Metal-binding peptide sequenced NLNPNTASAMHV was taken as the target peptide to interact with stainless steel. The surface morphology, roughness and Fourier-Transform Infrared spectroscopy (FTIR) showed that some changes occurred on the modified stainless steel surface. Not only were the surfaces coarser but also some organic groups appeared on the modified sample surfaces. By comparing the CAs of all the samples, the most suitable concentration of peptide and treating time were determined. A new and facile way to endow some metals surfaces with hydrophobicity or hydrophilicity has been developed, which is useful especially for antibiofouling.

Some industrial applications require the use of self-lubricating materials when fluid lubrication cannot be used. Carbon-based materials and in particular graphites are usually a used solution. However, the application of these materials is limited at high temperature; these materials are exposed to significant degradation and to high friction due to their high sensitivity to the air humidity and to the desorption phenomenon. This study determines the influence of a specific metallic impregnation on the graphite bearing, which is submitted to a severe thermo-vibratory loading by fretting against a stainless steel surface. The stainless steel surface has undergone a nitriding treatment by plasma. During the fretting contact, a strong transfer of the impregnant takes place from the impregnated graphite bearing to the steel conterface by adhesion; this deposit film allows a significant improvement in the tribological properties of the contact surfaces at high temperature.

Abstract Total organic carbon (TOC) analysis can be used in many cases as a nonspecific method of determining trace levels of organic residue on manufacturing equipment before and after cleaning. In this study, a swab sampling method followed by TOC analysis is used to determine organic residue levels associated with alkaline and acidic cleaning agents on a stainless steel surface. The alkaline cleaning agent was nonvolatile, resulting in favorable TOC analysis and validation. The acidic cleaning agent was very volatile, requiring more skilled sample handling and resulting in a more difficult validation. Fourier-transform infrared (FTIR) spectroscopy with a grazing-angle sample attachment can be used for direct surface measurements of cleaning-agent residues on a stainless steel surface. FTIR spectroscopic studies complement and support the TOC studies. One band chosen for each cleaning agent was monitored throughout the leaning process. cidic and alkaline

Sticking Coefficients

ABSTRACTSticking coefficients γ of neutral transient species at ambient temperature were measured using in situ Resonance Enhanced Multiphoton Ionization (REMPI) of the transients in a Knudsen cell. γ for I and CF3I‡ on a stainless steel surface were 0.16 and >0.5, respectively, whereas γ for CF3 on the same surface was measured to <0.01; γof SiH2 on a growing carbon containing amorphous silicon surface was 0.11; this value increased to 0.15 for interaction of SiH2 with a “pure” growing silicon-hydrogen surface, and γ of SiH2‡ on both types of surfaces was found to be >0.5.
