Development of a mussel-inspired conductive graphene coated cotton yarn for wearable sensors by Guanliang He, Chuang Zhu, Yuze Shi, Yingjia Yu, Yi Wu, Constantinos Soutis, Le Cao, Xuqing Liu

“…Herein, we produce a flexible polydopamine (PDA)-modified cotton yarn via a simple dip-coating process using a self-made sodium deoxycholate (SDC)-modified graphene dispersion, avoiding non-biodegradable, corrosion-prone metallic coatings. The resulting sensor exhibits low electrical resistance (as low as 21.1Ω ± 0.2/cm), high bending sensitivity (resistance change rate of 3.557 ± 0.002 for bending ranges from 40% to 100%), and outstanding durability over 2,000 flexural bending cycles. …”

Activation of diffusion during the formation of boride layers on the surface of steel parts by S. M. Usherenko, V. G. Dashkevich, Yu. S. Usherenko

“…In both cases, a change in morphology was noted, consisting in the formation of a more compact diffusion layer and rounding of boride needles in the zone adjacent to the base metal. An increase in the layer thickness by 20–50 % and an increase in the proportion of the high-boron FeB phase relative to the variant of borating without preliminary activation were established.…”
