Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation

open access: yesAdvanced Robotics Research, EarlyView.
This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...

Application of resistive super conductor fault current limiter for protection of grid-connected DGs

open access: yesAlexandria Engineering Journal, 2018
Penetration of Distributed Generation (DG) into the power system causes technical problems and bad effects on the safety of the system due to increasing the short circuit levels in transmission and distribution networks. So, there will be miscoordination

Recyclable All‐in‐One Organo‐Photo‐Auxiliaries Enabling (sp3)C−(sp3)C Coupling Reactions with Diverse Functionalities

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Photochemical C−C coupling reactions can be tailored to industrial chemical processes and preparations of pharmaceuticals. Recent approaches in this area are limited to using precious transition metal coordination complexes that facilitate light absorption and redox processes with benchtop chemicals. Herein, we propose a paradigm that involves

Impact of the Si Electrode Morphology and of the Added Li‐Salt on the SEI Formed Using EMIFSI‐Based Ionic‐Liquid Electrolytes

open access: yesAdvanced Sustainable Systems, EarlyView.
The early‐stage formation and evolution of the solid electrolyte interphase (SEI) on binder‐free silicon electrodes is investigated by advanced spectroscopic techniques and controlled galvanostatic cycling. The influence of electrode crystallinity and morphology on passivation film composition and thickness is demonstrated, offering valuable insights ...

Mechanical Interactions Impact the Functions of Immune Cells and Their Application in Immunoengineering

open access: yesAdvanced Therapeutics, EarlyView.
This review covers the mechanical forces experienced by immune cells through cell–cell and cell–extracellular matrix interactions and how these forces influence their receptors and functions. These relationships between forces and cellular functions can be exploited using engineering techniques to modify the physical properties of materials for novel ...
