The viability of slim-hole drilling onshore Trinidad
Journal of Petroleum Exploration and Production Technology, 2018 Slim-hole drilling refers to the drilling of a well with a wellbore typically less than 7 in. in diameter. Slim-hole drilling is beneficial to the low-budget operator as there are considerable savings on rig time and costs and the rig size is ideal for ...

Pressure‐Induced Structural and Magnetic Evolution in Layered Antiferromagnet YbMn2Sb2
Advanced Electronic Materials, EarlyView.Pressure tunes the delicate balance between structure, magnetism, and electronic states in quantum materials. In YbMn2Sb2, high‐pressure X‐ray and neutron diffraction reveal a trigonal‐to‐monoclinic transition near 3.5 GPa, accompanied by unconventional magnetic ordering.

Self‐Sensing Artificial‐Muscle‐Empowered Humanlike Perception, Interaction, and Positioning
Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.The proposed self‐sensorized artificial muscle (SSAM) can sense its length change as small as 0.01 mm via a seamlessly integrated multi‐segment induction coil. The SSAM provides accurate length information regardless of its loadings, driving pressure, or muscle design, adequate for robust data‐driven feedback control.

Modeling and Characterization of a Self‐Sensing Soft Hydraulic Muscle
Advanced Intelligent Systems, EarlyView.This article presents the self‐sensing soft hydraulic muscle (SSHM), a novel soft actuator capable of simultaneously sensing force and length without external sensors. A comprehensive model accurately predicts SSHM behavior, validated experimentally with minimal errors. Using propylene glycol enhances durability and reduces hysteresis.

Scalable High‐Force Zipping Electrostatic Actuators
Advanced Intelligent Systems, EarlyView.An electrostatic actuator architecture is presented that combines high energy density with forces and strokes suited for wearable soft robotics. By folding patterned thin films into a scalable honeycomb of zipping units, performance becomes tunable through series–parallel design, achieving over 40 N and 28 J/kg.
