Superhydrophobic surfaces have already been applied in anti-fouling, water-oil separation, liquid transportation, etc. Surfaces can be defined as superhydrophobic once they support a water droplet with its spherical shape maintained and accompanied by an apparent contact angle larger than 150° rolling-off below 10°. Such repellent property is achieved the synergetic action of hierarchical struc...

Self-healing is an ideal mechanism for concrete to achieve self-repair of microcracks . While extensive efforts have been invested in capsule-based autonomous self-healing, the dilemma between capsules’ survivability during mixing and their rapture upon cracking release healing agents remains unsolved. This study aims address this challenge by investigating a lignin-based capsule system with tu...

Quasi-brittle materials such as concrete suffer from cracks during their life cycle, requiring great cost for conventional maintenance or replacement. In the last decades, self-healing materials are developed which are capable of filling and healing the cracks and regaining part of the stiffness and strength automatically after getting damaged, bringing the possibility of maintenance-free mater...

Self-healing technology offers an autonomic route to repairing damage in advanced polymers to extend their lifetime. A variety of self-healing systems have been developed for mechanical self-healing, protective coatings, and electronic self-healing. These self-healing systems rely on functional groups within the polymer, microvascular networks, or compartmentalization in capsules and particles....

Anomaly-based Intrusion Prevention Systems (IPSs) currently protect systems from zero-day attacks. However, since they either only inform administrators about the intrusions and/or just stop services or systems, they cannot stably continue services until the vulnerabilities are fixed by security patches. So self-healing systems (SHSs) are needed because they continue to safely execute services ...
