Materials | Free Full-Text | Design of Friction Stir Spot …

A simple thermal-mechanical model for friction stir spot welding (FSSW) was developed to obtain similar weld performance for different weld tools. Use of the thermal-mechanical model and a coined approach enabled the design of weld tools for various sizes but similar qualities. Three weld tools for weld radii of 4, 5, and 6 mm were made to join 6061-T6 aluminum sheets. Performance

Siloxane - an overview | ScienceDirect Topics

Siloxane polymers have been widely used in antimicrobial and nonfouling surfaces, but their use as solution-based antimicrobials is far more limited. Sauvet et al. 105 developed a postfunctionalizaton method to create quaternary ammonium-containing siloxane polymers (C14) (Figure 20).).

Gravimetric analysis - Wikipedia

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion''s mass has been determined as a unique compound, that known measurement can then be used to determine the same

CONTROLLED MOLECULAR ADSORPTION ON SILICON: …

This review is about understanding and controlling organic molecular adsorption on silicon. The goal is to provide a microscopic picture of structure and bonding in covalently attached molecule-silicon surface systems. The bias here is that an unprecedented, detailed understanding of adsorbate-surface structures is required in order to gain the control necessary to incorporate organic function
