Geodesic continued fractions and LLL [PDF]

open access: yes, 2013
We discuss a proposal for a continued fraction-like algorithm to determine simultaneous rational approximations to $d$ real numbers $\alpha_1,\ldots,\alpha_d$. It combines an algorithm of Hermite and Lagarias with ideas from LLL-reduction. We dynamically

Electroosmotic Pumps with Frits Synthesized from Potassium Silicate. [PDF]

open access: yesPLoS ONE, 2015
Electroosmotic pumps employing silica frits synthesized from potassium silicate as a stationary phase show strong electroosmotic flow velocity and resistance to pressure-driven flow. We characterize these pumps and measure an electroosmotic mobility of 2.

Utilization of waste glass with natural pozzolan in the production of self-glazed glass-ceramic materials

open access: yesNanotechnology Reviews, 2023
Significant self-glazed glass-ceramic was obtained from a natural pozzolan and external glass cullet. Natural pozzolan with/without glass cullet was fused to glass melt that quenched in water to glass frits. The dried glass frits were pulverized (
