Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract
Advanced Robotics Research, EarlyView.We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Study of lubricant jet flow phenomena in spur gears: Out of mesh condition [PDF]
, 1983 The penetration depth onto the tooth flank of a jet of oil at different velocities pointed at the pitch line on the outgoing side of mesh was determined. The analysis determines the impingement depth for both the gear and the pinion.

Capillary pinching in a pinched microchannel [PDF]
, 2007 We report a study of the capillary pinching of a gas bubble by a wetting liquid inside a pinched channel. The capillary pinching induces very reproducible bubbling, at a very well-defined frequency.

Large-bore tapered-roller bearing performance and endurance to 2.4 million DN [PDF]
, 1983 The operating characteristics and experimental life estimates for 120.65 mm bore tapered roller bearings of two designs under combined radial and thrust loads were determined. A modified standard bearing design was tested at speeds up to 15,000 rpm.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Water pollution by oil and organic substances causes serious problems that threaten the ecosystem. Superhydrophobic materials represent an effective solution for removing oil from water. The present paper investigates the development of a low‐cost, superhydrophobic composite for oil–water separation.
