Orderly polymer nano-fibers (5 to 10 μm in length/100 nm in width) with a certain direction are obtained due to an external macroscopic force 'Fblow,' which is on the same direction as the H2 gas flow.
Polymer chains stretched and elongated freely to form a disordered micro-nano-scale grass/leaf-like morphologies in pure PTFE coating (P1 coating), while orderly polymer nano-fibers (100 nm in length/5 to 10 μm in width) with a certain direction are obtained by the force Fblow along the direction of H2 gas flow.
Orderly thin (100 nm) and long (5 10 μm) polymer nano-fibers with a certain direction are fabricated by external macroscopic force (Fblow) interference introduced by H2 gas flow, leading to superior superhydrophobicity with a water contact angle (WCA) of 170° and a water sliding angle (WSA) of 0-1°.
The paper suggests a qualitative approach to systematically analyzing trends relevant for the future by using the concept of megatrends, as fundamental, long lasting, global or international transformation processes with a certain direction, including the economic and the socio-cultural dimension and affecting multiple aspects of life [5].
The team grew up from pre-season with him and the team went in a certain direction with a style of play.

If you're using your iPhone, for example, and dragging a photo in a certain direction with your finger and then stop, the photo shouldn't just stop moving.
People expect me to go a certain direction with videos, but the rules I gave the director of all the other videos are: no cars, no driving cars, no standing by cars, no sitting at a table with bottles of champagne, no opening mansion doors, no swimming pools with girls in bikinis, no violence and no booty shakin.'.

The way one side is stretched and the other compressed indicates movement in a certain direction and with a certain force.
