copper indium gallium selenide (cigs) is one of only a few materials currently used commercially for the production of thin-film photovoltaic devices. additionally, many indium semiconductors are being investigated for potential use in novel nanoengineered forms such as quantum dots and nanowires ....
extraordinary mechanical, chemical, thermal and optical properties. with a relative transparency of over %, ceramtec perlucor® opens up new fields of application everywhere glass reaches its limits. the latest perlucor® news: - - reliable transparency with perlucor® - - document scans in the highest...
pure metallic gold are as follows: it is the most malleable and ductile of metals and an unusual color for elementsof that class, is mostly non-reactive, conducts electricity well, and is extremely dense. the density of gold helped to drive its relative rarity, as gold present when the earth was formed...
california, from which it takes its name. though it was the sixth transuranic element to be artifically produced in a lab, it does occur naturally in extremely small amounts via the decay cycles of other elements and in fact is the heaviest element for which this is the case; all elements the follow...
the advent of new green chemistry and hazardous materials legislation such as the reach program in the european union.for example, bromides are now being used in many catalytic, electronic , coating and biomedical applications in replacement of other soluble forms for this reason. recent research &...
except for helium and hydrogen ; it is one of three elements that can float on water (fellow alkali metals sodium and potassium being the other two). lithium also has the highest specific heat and electrochemical potential of all elements and is the only stable light element that can produce net energy...
of a white light into components of different wavelengths prism is also a dispersive medium, used to break up light into its constituent spectral colors. light is a source of energy plastic is not a threat to glass since glass has several advantages in terms of physical and chemical properties and abundant...
nitric acid; copper sulfate is a common algicide . recent research & development for sulfates the effects of nonredox metal ions on the activation of peroxymonosulfate for organic pollutants degradation in aqueous solution with cobalt based catalysts: a new mechanism investigation. , xu, aihua, wei...
rare earth oxides. he isolated two new oxides, which eventually led to the identification and naming of the elements holmium and thulium. thulium is named after thule, scandinavia. despite being very rare and expensive, thulium has several commercial uses. notably, it is used as a dopant for garnets...
