Journal of the Science of Food and Agriculture, EarlyView.Abstract The papaya tree (Carica papaya L.), native to the Americas, is cultivated in tropical regions and holds substantial economic importance, with an estimated export volume of 365 000 t in 2023. However, diseases caused by viruses, fungi, bacteria, and nematodes can lead to severe losses.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies

AFM study of oxygen reduction products on HOPG in the LiPF6–DMSO electrolyte [PDF]
, 2013 Ex situ atomic force microscopy (AFM) has been used to study the morphology of oxygen reduction products in the LiPF6–dimethyl sulfoxide (DMSO) electrolyte, i.e. Li2O2 on a highly oriented pyrolytic graphite (HOPG) surface.

Defect Passivation via Plasma Modification of Lead Halide Perovskite Thin Films
Progress in Photovoltaics: Research and Applications, EarlyView.We demonstrate that exposure of perovskite thin films to diffuse coplanar surface barrier discharge nitrogen plasma leads to an increase in photoluminescence, attributed to reduced defect densities. This results in implied open‐circuit voltage improvement of up to 80 mV and finalized solar cell open‐circuit gains up to 60 mV.
