Oxygen Evolution Electrocatalysts with Trinuclear, Mixed‐Valence Iron Motifs on Electronically Aligned Carbon Dots

open access: yesAdvanced Functional Materials, EarlyView.
Trinuclear iron oxo‐bridged catalytic ensembles stabilized by aspartic‐acid‐derived carbon dots provide an effective platform for alkaline oxygen evolution. Mixed‐valence charge balancing, inner‐sphere charge transport, and work‐function alignment within the N/O‐rich carbon framework promote cooperative Fe‐site chemistry and efficient OER ...

Manipulability Analysis of Redundant Robotic Manipulator

Proceedings of the 21st International Conference on Computer Systems and Technologies, 2020
The increased number of applications of the robotic systems in the human life leads to the need of assigning more complex tasks to such systems. The redundancy of the robotic configuration increases performance and precision of the execution of the assigned tasks.

Cheope: A New Reconfigurable Redundant Manipulator

open access: yesMechanism and Machine Theory, 2010
This work presents a new reconfigurable parallel-serial hybrid manipulator that can reach 7 degrees of freedom as a whole. The architecture of the parallel part is modular and it can be configured to obtain for the mobile base 3 or 4 degrees of freedom ...
