Atomic mass:The standard atomic weight of an element is the average mass of the element written in atomic mass units (amu). Even though each atom has roughly a whole number of atomic mass units, you will notice that the atomic mass on the periodic table is a decimal; that's because the...
electron micrograph of that device.) At about the same time, in aCNET interview, Micron’s then-CEO Mark Durcan explained that the company planned to sample 3D NAND in the first quarter of 2014, but indicated that the company’s 3D timing would be determined by strategy, and not technology...
According to the Bohr model, often referred to as a planetary model,the electrons encircle the nucleus of the atom in specific allowable paths called orbits. When the electron is in one of these orbits, its energy is fixed. ... The electron is not allowed to occupy any of the spaces in...
2D and DOSY NMR spectroscopies support the sandwiched binding mode based on 1:1 host-guest interactions. The binding constants (K(S)) of complex 1 for various PAHs were determined by NMR titration studies and the values were found to span up to an order of 10(4) M(-1) for coronene ...
the last centuries. They were determined not to repeat that mistake of the old European colonial powers when it came to decide on the legal status of the moon; at least the possibility of a "land grab" in outer space giving rise to another world war was to be avoided. By that token,...
A Swede who wrote a trilogy about collecting bugs, an Egyptian doctor who put pants on rats to study their sex lives and a British researcher who lived like an animal have been named winners of the Ig Nobels, the annual spoof prizes for quirky scientific

and dissolving in nitric acid. Digestion in Aqua Regia was additionally carried out to detect the presence of rare and refractory elements. Weight loss after ignition at 1000 °C was carefully registered and determined the loss on ignition value. Due to their light weight, 10 samples were analyz...
Many current reports in the scientific literature describe novel fluorescent probes intended to provide information on various structures or properties of live cells by using microscopic imaging. Unfortunately, many such reports fail to provide key infor
