Core drill's bit is replaceable without withdrawal of drill stem - A concept [PDF]
, 1970 Drill bit is divided into several sectors. When collapsed, the outside diameter is forced down the drill stem, when it reaches bottom the sectors are forced outward and form a cutting bit.

A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?
Advanced Engineering Materials, EarlyView.Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Advanced Engineering Materials, EarlyView.The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Proceedings of the National Academy of Sciences, 2013 For scientists who study subseafloor sediment, it’s not unusual to spend a lot of time at sea aboard a ship with a gaping hole in its hull. Known as a moon pool, the hole serves as a portal for the ship’s weighty drilling equipment to retrieve core samples of seafloor sediment thousands of meters below. Aboard …
