"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.
«Стакан апельсинового фреша 250 мл это 100–130 ккал. Облепиховый напиток с медом 300–400 миллиграмм это 150–250 килокалорий. Смузи из банана, ягод, йогурта и меда это 200–350 килокалорий. Модный боул с фруктами, гранолой, орехами и медом легко тянет на 400–700 килокалорий. И все это поверх обычной еды, а не вместо», — сказал эксперт.
