Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

Advanced Robotics Research, Volume 2, Issue 4, August 2026.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Nutritional Composition of African Catfish (Clarias gariepinus) in Ghana: Effects of Culture Conditions, Feed and Processing

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
This review synthesizes current evidence on the nutritional composition of African catfish (Clarias gariepinus), with emphasis on Ghanaian aquaculture. The species is a valuable source of high‐quality protein, essential amino acids, minerals and vitamins, although lipid composition varies widely.

Bright and Durable Copper‐Iodide‐Based Nanowire Scintillators

Aggregate, Volume 7, Issue 8, August 2026.
A surface‐protective‐agent (SPA)‐coordinated low‐temperature crystallization strategy regulates the surface microenvironment of CsCu2I3 nanowires at the atomic level. The SPA simultaneously suppresses iodine‐vacancy‐related defects and nonradiative recombination while eliminating Cu2+ species and surface oxide formation, offering a coherent pathway to ...
