Experiment and Simulation of Self-excited Torkbuster
The stick-slip vibration is a technical bottleneck restricting for PDC bit in efficient drilling deep hard formation. To reduce the stick-slip vibration of drill bit during drilling deep hard formations, a torkbuster has been introduced.

NiFe‐NO3 Layered Double Hydroxide as a Novel Anode for Sodium Ion Batteries
This study demonstrates, for the first time, the effectiveness of using LDH as an anodic material in SIB. The material is stable and show high specific capacity, the reaction mechanism has been thoroughly investigated and comprehensively described and involves a phase change reaction followed by sodium intercalation.

Bricks, knots, and bodies: Material encounters and the affective making of masculinity
Abstract This paper examines how creative research methods do not just capture boys' experiences of masculinity, but actively materialise them. Drawing on two arts‐based activities used in school‐based fieldwork (a mannequin‐based exercise with one participant and a Lego‐building workshop with a small peer group), the paper analyses how materials ...

The novel ITO protective layer enables ultra‐stable Zn metal anodes. By synergistically accelerating Zn2+ desolvation and Zn2+ transport via its unique structure, the ITO layer suppresses dendrites and side reactions. This results in exceptional stability for over 6000 h at 2 mA cm–2 and stable operation in Zn ||MnO2 full‐cell configurations.

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an
