Microwave-assisted chemistry is becoming very attractive in all areas of synthetic chemistry;
it is fast, easy to operate, efficient in terms of energy consumption and environmentally …

The normal and friction forces between layers of three fatty acids (stearic, oleic, and linoleic
acid) and a rosin acid (dehydroabietic acid) have been measured in n-hexadecane with a …

Tungsten skarns today represent> 40% of the global tungsten reserves although their
processing is usually difficult due to the fine textures, low grade, and complex mineralogical …

Surfactin is a lipopeptide produced by various strains of Bacillus subtilis and is a very
powerful surfactant. Here we present the first report on the interfacial behavior of surfactin …

The adsorption of the unsaturated fatty acids oleic, linoleic, and linolenic acid on steel
