Article Abstract
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 2.5 × 10(-8) m(2)/V s and hydrodynamic resistance per unit length of 70 × 10(17) Pa s/m(4) with a standard deviation of less than 2% even when varying the amount of water used in the potassium silicate mixture. Furthermore, we demonstrate the simple integration of these pumps into a proof-of-concept PDMS lab-on-a-chip device fabricated from a 3D-printed template.

Hyperkalemia is a common and serious complication in dialysis patients, with increased incidence and severity over time. Newer potassium binders, patiromer and sodium zirconium cyclosilicate (SZC), offer improved tolerability compared to older agents. This meta-analysis aims to evaluate the efficacy and safety of these newer binders in dialysis patients.

Determining the composition, formation mechanisms and stability of the Hadean continental crust is essential for understanding the early geological history of Earth. Detrital zircons, largely from Jack Hills of Western Australia, provide the dominant direct records for the nature of continental crust during the Hadean eon and its formation processes. Although isotope and trace element compositions of these zircons are extensively determined, the major and trace element compositions of their host rocks and corresponding parental magmas remain largely debated, making the nature and evolution of the early Earth's crust ambiguous.

This study was conducted during the 2024 growing season at the Palm Research Station in Al-Zafaraniya, Baghdad, Iraq. A total of 54 uniform date palm trees (Khastawi and Khadhrawi cultivars), approximately 15 years old and planted at 10-m spacing, were selected for experimental treatments. The objective was to evaluate the effects of three concentrations of nano NPK fertilizer (0, 2, and 4 g·L), applied in six foliar doses, and three concentrations of potassium silicate (0, 2, and 4 mL·L), applied in four foliar doses, as well as their interaction, on date yield, and fruit quality.

Eggplant, an important global crop, faces severe threats from Rhizoctonia solani, causing damping-off, root rot, and stem canker. Conventional control methods are often ineffective, necessitating sustainable alternatives. This study investigates the synergistic potential of arbuscular mycorrhizal fungi (AMF) and silicon (Si) to enhance eggplant resistance against R.

Lignite coal is the primary local energy source in Türkiye. The inevitable result of the utilization of lignite coal in thermal power plants for electricity generation is the formation of large amounts of ash (bottom ash and fly ash) as industrial solid waste. These wastes contain technologically enhanced natural radionuclides in the uranium (U) and thorium (Th) decay series and radio-potassium (K).
