Soft Microrobots Employing Nonequilibrium Actuation …

Mechanical actuation also in nature is frequently caused by swelling and unswelling of hydrogels. In cases like the hydraulic opening and closing of a pine cone this is not tied to mechanisms of living matter. Still the motion can be fast and complex. 14 Intrigued by these examples, an increasing interest has develped in artificial hydrogel actuator systems that exploit swelling/unswelling in

Changes in soil organic carbon and microbial community …

1. Introduction Soil organic carbon (SOC) accounts for about 60 % of soil organic matter, and it plays an important role in improving soil fertility and sustaining soil productivity (Chen et al., 2017).Studies have suggested that with an increase in SOC by 1 g kg −1, crop yield in summer maize and winter wheat rotation can increase by about 500 kg ha −1 in the North China (Qiu et al., 2009).
