  • Rutherford (also Geiger-Marsden) Experiment (1911): Measured angular dependence of   particles (He ions) scattered from gold foil. The results: • Mostly scattering at small angles. But… • Occasional scatterings at large angles (even 90o)  Something massive in there ! Conclusion: Most of atomic mass is concentrated in a small region of the atom Recall some history:

  • The second edition of Atoms, Radiation, and Radiation Protection has several important new features. SI units are employed throughout, the older units being de-fined but used sparingly. There are two new chapters. One is on statistics for health physics. It starts with the description of radioactive decay as a Bernoulli process and treats sample counting, propagation of error, limits of detection, type-I and type-II errors, instrument response, and Monte Carlo radiation-transport computations.

  • Enzymes are proteins that catalyze chemical reactions. A protein is simply a polypeptide composed of amino acids linked by a peptide bond, and the term generally, but not always, refers to the folded conformation. To understand how an enzyme functions, including its binding and functional properties, it is necessary to know the properties of the amino acids and how the amino acids are linked together, including the torsion angles of the bonds and the space occupied, and the interactions of the atoms leading to the final conformations of the folded protein.

  • This is the first book to cover the history, structure, and application of atomic force microscopy in cell biology. Presented in the clear, well-illustrated style of the Methods in Cell Biology series, it introduces the atomic force microscope (AFM) to its readers and enables them to tap the power and scope of this technology to further their own research. A practical laboratory guide for use of the atomic force and photonic force microscopes, it provides updated technology and methods in force spectroscopy.

  • Carbon nanotubes are rolled up graphene sheets with a quasi-one-dimensional structure of nanometer-scale diameters. More than twenty years have passed since the pioneering work on carbon nanotubes by Prof. Iijima in 1991. During all these years, carbon nanotubes have at‐ tracted a lot of attention from physicists, chemists, material scientists, and electronic device engineers because of their excellent structural, electronic, optical, chemical, and mechanical properties.
