Optical trapping is a method for manipulating micro- and nanoscale particles that is widely used in biophysics and colloid science, among other areas. This
Superconducting measurements that help connect the unit of mass, the kilogram, to the Planck constant h are bringing the time when the scale for all units in
Metal amidoboranes, consisting of [NH 2BH 3]- anion and various metal cations, are a new class of compounds that have recently attracted great attentions due to
This chapter reviews calibration techniques relevant to aerosol measurement devices, such as sizing instruments, condensation nuclei counters, and mass monitors
Atomistic simulations, both electronic structure and non-quantum-mechanical methods such as molecular dynamics, are gaining in popularity and utility to treat a
Local oxidation by scanning probe microscopy (SPM) is used extensively for patterning nanostructures on metallic, insulating, and semiconducting thin films and
We review the status of neutron backscattering spectrometers on reactors and spallation sources including the most recent instrument developments. After setting

Light scattering belongs to a class of techniques known as area-integrating methods for measuring surface texture. Rather than being based on coordinate
The hp version of the finite element method (hp-FEM) combined with adaptive mesh refinement is a particularly efficient method for solving partial differential
We describe the use of x-ray induced fluorescence to study metal-halide high-intensity discharge lamps and to measure equilibrium vapor pressures of metal
Particle size characterization is of particular importance to nanomedicine as nano is a dimensional definition, and the size similarity of nanoparticles to
The introduction of rare earth atoms and molecules into lighting discharges led to great advances in efficacy of these lamps. Atoms such as Dy, Ho and Ce
