Fabrication of a planar micro Penning trap and numerical investigations of versatile ion positioning protocols

, 2010
We describe a versatile planar Penning trap structure, which allows to dynamically modify the trapping conguration almost arbitrarily. The trap consists of 37 hexagonal electrodes, each with a circumcirle-diameter of 300 m, fabricated in a gold-on ...

Removal of Inorganic Contaminants Using Sodalite Synthesized From Alum Sludge

Particle &Particle Systems Characterization, Volume 43, Issue 5, May 2026.
Alum sludge was successfully converted into sodalite adsorbent through a mild hydrothermal for contaminants adsorption in wastewater. ABSTRACT The growing concern over water contamination by potentially toxic metals underscores the need for sustainable and cost‐effective remediation strategies. In this study, sodalite (SOD‐Na) was synthesized from alum

Sub‐100 Nanometer Focusing of Hard X‐rays Using SU‐8 Compound Kinoform Focusing Lenses

Advanced Photonics Research, Volume 7, Issue 4, April 2026.
A novel aberration‐free X‐ray compound refractive lens design based on Cartesian oval curve is presented. Achieving a vertical focal spot size of 70.8 nm using knife‐edge scanning with a 200 μm incident aperture. Wavefront reconstruction via knife‐edge imaging further resolves a refined focal spot of 56 nm.
