The stand-alone microbeam, under development at RARAF, presents a novel approach to biological microbeam irradiation studies. Foregoing a conventional accelerator as a source of energetic ions, we propose to use a small, high-specific-activity, alpha

The microbeam facility at Columbia University is expanding current protocols for single-particle, single-cell irradiations, so experimenters can locate and irradiate nuclei and cytoplasm of unstained cells. The ion beamline is located directly under

The Columbia University Microbeam II has been built to provide a focused ion beam for irradiating designated mammalian cells with single particles. With the interest in irradiating non-stained cells and cells in three-dimensional tissue samples, the

A single-cell/single-particle microbeam has been designed in which the radiation source is a high specific-activity alpha-particle emitting radioisotope, rather than a particle accelerator. The source is imaged at the focal point of a compound magnet

A detailed study of the alkaline modification of poly(vinylidene fluoride) (PVdF) by a phase transfer catalyst (PTC) medium has been carried out by X-ray photoelectron spectroscopy, (XPS), secondary ion mass spectrometry (SIMS) and Raman spectroscopi

The alkaline treatment of poly(vinylidene fluoride) (PVdF), in the presence of phase transfer catalysts (PTCs) has been investigated. Rutherford backscattering spectrometry (RBS) has been used to determine the depth of modification achieved and to pr

Microrelief affected the drainage conditions within a sandy podzolic pedon in southeastern Quebec, Canada, which in turn affected soil pH, organic C and extractable Al, Fe and Si within the studied pedon. Imogolite was found in the profiles in the hi
