This study investigated the one-pot hydrothermal synthesis of mixed-phase ion-exchangers from waste amber container glass and three different aluminium sources (Si/Al = 2) in 4.5 M NaOH(aq) at 100 °C. Reaction products were characterised by X-ray diffraction analysis, Fourier transform infrared spectroscopy, 27Al 29Si magic angle spinning nuclear magnetic resonance spectroscopy scanning electro...
The development of new active optical fibre devices requires materials with « augmented » intrinsic properties, though using luminescent ion (LI) –doped silica as host glass. Optical fibers containing Dielectric Nanoparticles (DNP) grown by phase separation are proposed. DNP would optimally fully encapsulate LI to produce « engineered » spectroscopic properties. To determine the composition of ...
When an ion beam is injected into a tapered insulating capillary, the induced self-organized radial Coulomb potential in capillary able to focus like electrostatic lens. However, because of continued accumulation charge equilibrium rarely attained and eventually blocked by capillary's potential. We propose original add-on setup, which can be tested experimentally expected hinder blocking. inves...
The characteristics of inorganic particles generated in glass vials filled with phosphate buffer solutions were investigated. During storage, particles were visually detected in the phosphate buffer solution in particular glass vials which pass compendial tests of containers for injectable drugs. These particles were considered to be different from ordinal glass delamination, which has been rep...

We present evidence of the focusing effects of fine glass capillary optics for MeV He ion beams. The glass capillary optics are formed by a puller as to have inlet diameters of about 1 mm and outlet diameters of submicrons. The total length of the optics is about 50 mm. Impingent MeV ions to such optics are reflected by the inner wall several times, in a very similar process to the so-called su...
Previously observed non-Arrhenius behavior in fast ion conducting glasses [J. Kincs and S. W. Martin, Phys. Rev. Lett. 76, 70 (1996)] occurs at temperatures near the glass transition temperature, T(g), and is attributed to changes in the ion mobility due to ion trapping mechanisms that diminish the conductivity and result in a decreasing conductivity with increasing temperature. It is intuitive...
A new family of polymer-based ion exchangers was tested for the purification of acidic and basic proteins on both the analytical and preparative scales. Protein-Pak HR series packings are available as strong cation (SP) and weak anion (DEAE) exchangers, allowing the development of a purification method regardless of the isoelectric point of protein. Three particle sizes, 8, 15 and 40 microns, a...
We developed a new glass-tube-pair type Doppler probe array for 1D ion velocity vector and temperature measurement. It needs just two parallel glass-tube insertion, realizing low plasma perturbation flow measurement on single discharge. Using four mirrors optical fibers one point, this system can measure local light emissions of each volume from different directions, enabling us to temperature....
