Palladium (Pd) nanostructures are highly active non-platinum anodic electrocatalysts in alkaline direct methanol fuel cells (DMFCs), and their electrocatalytic performance relies highly on their morphology and composition.This study reports the preparation, characterizations, C Cell Ni-Cd and Ni-Mh Batteries and Battery Packs and electrocatalytic p
Microbial pesticides: challenges and future perspectives for non-target organism testing
Abstract Biopesticides have received increasing global attention as environmentally friendly alternatives, allowing for more sustainable pest and disease control.In order to be registered or authorized for use, safety studies need to be submitted for Clipper regulatory risk assessments.However, it has been frequently reported that, in particular, m
Dynamic modeling and motion characteristics analysis of variable-length aerial refueling hose-drogue system
During the aerial refueling process, the hose-drogue is disturbed by the complex airflow to occur irregular shaking motion, while the hose-drogue in the impact of the receiver often lead to whipping phenomenon, C Cell Ni-Cd and Ni-Mh Batteries and Battery Packs limiting the success rate and safety of refueling.In order to study the motion character
Empirical research on the evolution trend of heat and sentiment for emergencies
Emergencies inflict heavy casualties, economic losses, ecological damage, and significant social harm to society.By segmenting information topics and analysing emotional shifts, we can identify corresponding real-world events and their impacts, thereby providing guidance for timely responses to emergencies.In the past, public opinion monitoring of
