Feline‐Inspired Robot Enabled by Combustion‐Driven Actuators for Agile Motion and High‐Payload Obstacle Traversal

open access: yesAdvanced Science, Volume 13, Issue 18, 27 March 2026.
Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Computational Analysis of Spray Angle Effects on Combustion and Emissions in Methane‐Diesel Dual‐Fuel Engine

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1100-1112, March 2026.
This study concluded that wider spray angles produce wall impingement and greater unburned hydrocarbons in methane‐diesel dual‐fuel engines, whereas 110° balances efficiency and emissions. ABSTRACT A diesel methane dual fuel engine appears as a potential means for lowering emissions while retaining useful thermal efficiency.
