Miyaguchi et al.[6] analyzed friction torque of single-nut and double-nut ball-screw by the use of theoretical method and experiment.
Wei et.al. [7-9] established a transmission analytical model in disscussing variation of contact geometry and kinetical motion in a preloaded high rotational speed ball-screw.
The type of thermal radiation optical measurement is “Thermo-EL“.

The growth direction of the nanowire is [301], which is consistent with the results reported by Wang et al. [14] and Chen et al. [15].

Alloy 718 is a widely used Ni-base superalloy that is strengthened by γ'' (bct, Ni3Nb) precipitates. 718Plus is a new Ni-base superalloy recently introduced by ATI Allvac. 718Plus is strengthened primarily by γ' (fcc, Ni3(Al,Ti)) precipitates, but also contains some γ'' precipitates.

Zhang, et al. [5] reported that the incorporation of 50 wt.% of MCC as a reinforcement agent in polylactic acid (PLA) improved the flexural strength, flexural modulus and impact strength compared to the neat biopolymer.
Indarti, et al. [24] stated that although MCC is a material with many desirable properties, utilizing it is challenging because hydrogen bonding between its intermolecular chains may result in agglomeration when MCC particles are close to one another.
