    The volume of the generated H 2 and splitting time show a linear relationship with a slope of mL min-1 at 600 rpm. In addition, when the pure water was selected as electrolyte instead of KOH solution, the TENG-driven system produces four H 2 bubbles in 90 s with a voltage of 10 V that is four times the electrochemical workstation. This indicates that the high voltage of the TENG is capable of prevailing over the high load, which is also the advantage of TENG in pure …

The aspect ratio of drilling depth to input radius is slightly higher but in good agreement with the estimation from Eq. . This shows that the model for percussion drilling can also be applied for circular path drilling and gives good estimates.

    This effect was observed both for CNT and CCNT composites, with about double the surface area in the case of 10 wt% CNT or CCNT content (∼ 80 m 2 g −1 for the two composites vs about 40 m 2 g −1 for BC and 44 m 2 g −1 for regenerated BC). The absorbing capacity of the materials was then studied using four different oils, namely, paraffin, sunflower seed oil, vacuum oil and propanetriol.

    Metallic bonds are not as strong as ionic and covalent bonds. Metallic bonds are responsible for the main properties of metals, such as ductility, where the metal can be easily bent or stretched without breaking, allowing it to be drawn into wire. The free movement of electrons also explains why metals tend to be conductors of electricity and heat.
