Untethered Autonomous Holonomic Mobile Micromanipulator for Operations in Isolated Confined Spaces

open access: yesAdvanced Intelligent Systems, EarlyView.
Herein, a lightweight (515 g), compact (10 cm3), untethered holonomic mobile micromanipulator powered by piezoelectric actuators is presented. It autonomously manipulates mm to sub‐mm objects and droplets in narrow, hazardous spaces, achieving 0.18 ± 0.51 mm positioning accuracy and −0.4° ± 1.2° angular deviation.

Consequences on Acidity and Reactivity of Inhomogeneous Sodium Exchange in the Shaping of ZSM‐5 with Silica Binders

open access: yesChemCatChem, EarlyView.
The shaping of proton exchanged ZSM‐5 zeolites with silica is shown to strongly impact the properties of the samples, with strong variations depending on the silica source. The Brønsted acidity is measured thanks to pyridine thermodesorption monitored by FTIR and the catalytic activity in m‐xylene isomerization is quantified, which leads to an ...
