UTact: Underwater Vision‐Based Tactile Sensor with Geometry Reconstruction and Contact Force Estimation

open access: yesAdvanced Robotics Research, EarlyView.
Embedded flexible sensing technologies advance underwater soft robotics, yet most systems still suffer from hysteresis and limited perceptiveness. Instead, vision‐based tactile sensors provide reliable and rapid feedback essential for complex underwater tasks.

Improved boundary lubrication with formulated C-ethers [PDF]

open access: yes
A comparison of five recently developed C-ether-formulated fluids with an advanced formulated MIL-L-27502 candidate ester is described. Steady state wear and friction measurements were made with a sliding pin on disk friction apparatus.

Health Hazard Manual For Cutting Oils, Coolants, and Metalworking Fluids [PDF]

open access: yes, 1991
[Excerpt] The metalworker can be exposed to cutting oils during application by two basic routes of entry: skin contact and inhalation. The higher risk jobs tend to be those with high cutting speeds, heavy oil flow, and continuous contact, which may ...

Dual‐Functional Ingestible Passive Capsules for High‐Throughput Intestinal Sampling with Sealed Containment and Targeted Drug Delivery

open access: yesAdvanced Robotics Research, EarlyView.
To address challenges in high‐throughput intestinal sampling with sealed containment and target drug delivery, we developed a dual‐functional ingestible passive capsule with a dual‐triggered control system based on pH‐response and mechanical actuation.

Self-lubricating polymer composites and polymer transfer film lubrication for space applications [PDF]

open access: yes
The use of self-lubricating polymers and polymer composites in space is somewhat limited today. In general, they are only used when other methods are inadequate.

Tribological behavior of lubricants with and without nanoadditives: a compartive study [PDF]

open access: yes, 2011
Nano particle based additives have become a main focal point in the design of new lubricants, in order to better achieve reduction in both friction and wear.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

open access: yesAdvanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Applications of Phyllosilicates Mineral Powder as Anti-Wear Lubricating Materials in Lubricating Oil and Grease: A Review

open access: yesLubricants
Wear caused by friction is one of the main causes of most mechanical component failures. The application of powders as anti-wear lubricating materials has achieved great advances, which are of great significance in reducing friction and wear. This review

Shearing stability of lubricants [PDF]

open access: yes
Shearing stabilities of lubricating oils containing a high mol. wt. polymer as a viscosity index improver were studied by use of ultrasound. The oils were degraded by cavitation and the degradation generally followed first order kinetics with the rate of
