Electroosmotic pumps with potassium silicate frits

open access: yes, 2015
Electroosmotic pumps employing potassium silicate as a stationary phase show strong electroosmotic flow velocity and resistance to pressure-driven   flow. We characterize these pumps and demonstrate their simple integration into proof-of-concept PDMS lab-

NMR studies of silicate & aluminosilicate solutions [PDF]

open access: yes, 2001
The work described in this thesis deals with the use of (^29)Si and (^27)Al NMR to obtain information about the chemical structure of aqueous silicate and aluminosilicate solutions. This has extended the knowledge gained in previous studies. A wide range

Multichannel wavelength conversion of 40 Gbit/s NRZ DPSK signals in a highly nonlinear dispersion flattened lead silicate fibre

open access: yes
We experimentally demonstrate the wavelength conversion of three wavelength multiplexed 40 Gbit/s Differential Phase Shift Keyed (DPSK) signals in a 2.2m length of highly nonlinear, dispersion tailored W-type lead-silicate optical ...

The structure of a voltage gated potassium channel

open access: yes, 2010
Voltage gated potassium channels (Kv channels) are tetrameric ion channels, responsible for regulating the potassium component of the membrane potential in a large range of cell types ranging from mammalian excitable cells to bacteria. Attempts have been

Influence of Tapered‐End and Round‐End Bristle Designs on the Abrasive Enamel Wear Using Toothpastes With High Discrepancies in Abrasiveness

open access: yesInternational Journal of Dental Hygiene, Volume 24, Issue 4, Page 744-752, November 2026.
ABSTRACT Purpose The aim of this in vitro study was to investigate the influence of bristle end design of toothbrushes and the relative enamel abrasivity (REA) of used toothpaste on the resulting abrasive enamel wear. Materials and Methods A total of 160 bovine enamel samples were allocated into eight groups (n = 20) and surface topography was recorded

Screening of Ceramic Filler Materials for a Packed‐Bed Thermal Energy Storage System With Lead as Heat Transfer Fluid

open access: yesEnergy Storage, Volume 8, Issue 7, October 2026.
ABSTRACT Liquid lead (Pb) is an attractive heat transfer fluid (HTF) for packed‐bed thermal energy storage (TES) systems aimed for high temperatures. However, liquid Pb is corrosive and its corrosivity increases with rising temperature. Therefore, compatibility tests of possible filler materials with Pb are mandatory.
