When two or more atoms combine, they form a molecule, and if the atoms aren't the same element, the molecule is called a compound. Atoms combine to form molecules by sharing electrons. If one atom donates an electron, it's called an ionic bond, and if th
Physical perturbation of model membranes mimicking bacterial or mammalian cells was investigated using atomic force microscopy, polarized total internal reflection fluorescence microscopy, and NMR spectroscopy. Disruption of anionic membranes proceeds through a carpet or detergent model as proposed for other ...
Recently a new class of semiconductors has emerged, whose fundamental properties are dramatically modified through the substitution of a relatively small fraction of host atoms with an element of very different electronegativity, the so called highly mismatched alloys (HMAs). III-V alloys in which gro...
