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

2/12/2011· Herein, an on-chip approach to the rapid screening of experimental conditions pivotal to the production of nanostructures with different morphologies is reported. The key component of this approach is an array of reactors containing solutions with a one- or two-dimensional gradient in reagent concentration, pH value, or reaction temperature.

The inset of Figure 2(a)(i, iii, iv) shows the Sn3d 5/2 peaks of as-grown ITO, ITO after one hour hydrogen plasma treatment, and after two hours diamond growth, respectively. After plasma treatment and diamond growth, the sharp Sn 3d 5/2 peak of SnO at 486.10 eV diminishes, accompanied by the appearance and growth of another peak attributed to elemental tin at 484.4 eV with longer treatment …

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 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
12/9/2014· Franklin has joined the Department of Electrical and Computer Engineering in Duke University’s Pratt School of Engineering, with a joint appointment in the Department of Chemistry. Leaving IBM’s research enterprise for academia, Franklin will continue his research into semiconducting nanomaterials and printed electronics.

According to WHO, the main sources of human exposure to arsenic are water and food [].Inorganic arsenic in water is regulated [24, 25]; however, there is no European Union (EU) or United States of America (USA) standard for inorganic arsenic in food products, despite the fact that food products represent the main route of exposure, especially rice and rice-based products [26, 27].
Derivatization Derivatization is a specific chemical reaction, and a reactive functional group in the target compound and the corresponding reaction group(s) of derivatization reagent are the prerequisites for derivatization. From: TrAC Trends in Analytical Chemistry, 2014
Biomolecules including DNA, protein, and enzymes are of prime importance in biomedical field. There are several reports on the technologies for the detection of these biomolecules on various diagnostic platforms. It is important to note that the performance of the biosensor is highly dependent on the substrate material used and its meticulous modifiion for particular appliions. Therefore

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

26/1/2017· Of course, certain factors such as publishing earlier in the year, being featured in a special issue or being made open access may influence which items appeared on this list. To that end, ACS Axial will be publishing monthly updates on the most read chemistry articles of 2017 all year long.
18/9/2018· Carbothermic smelting of ores to produce metals or alloys in alternating current open/semiclosed and closed submerged arc furnaces, or in closed direct current furnaces, results in large volumes of CO-rich off-gas being generated. Most of the CO-rich off-gas is cleaned and flared on stacks, since the storing of large volumes is problematic due to the associated toxic and explosive risks
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand. SiO 2 Molar mass 60.08 g/mol
The approach was to make ion implant standards in sapphire for each element of interest and calibrate them with Rutherford backstering spectrometry (RBS). For those trace elements lighter than or close in mass to aluminum (i.e., Be, Mg, and Si), secondary ion mass spectrometry (SIMS) was used against multiple highly characterized standards kept by Evans Analytical.
