It has long been demonstrated the gecko‐inspired micropillar array with T‐shape tips possesses the best adhesion performance of a given material. The further enhancement of the adhesion performances of T‐shape micropillars can offer redundant adhesion to compensate for the inevitable improper contacts. Here, the array of T‐shape polydimethylsiloxane (PDMS) micropillars is incorporated with gradient dispersed calcium carbonate nanoparticles in the micropillar stalk, termed as T‐shape gradient micropillars (TG), possessing the modulus gradient with stiff tip and soft root. The gradient modulus in TG facilitates the contact formation and regulates the stress at the detaching interface, resulting in a 4.6 times adhesion and 2.4 times friction as compared with the pure PDMS T‐shape micropillar arrays. The study here provides a new design strategy for the super‐strong structured dry adhesives.

As profound net develops at a fast pace, there has been swollen enthusiasm for ways that assist proficiently with finding profound net interfaces. yet, thanks to the in depth volume of net assets and therefore the dynamic method of profound net, accomplishing wide scope and high productivity may be a testing issue. we have a tendency to propose a two-stage structure, above all SmartCrawler, for effective gathering profound net interfaces. within the initial stage, SmartCrawler performs site-based looking down focus pages with the help of net indexes, abstaining from going by incalculable. To accomplish a lot of precise results for AN engaged slide, SmartCrawler positions sites to prepare deeply pertinent ones for a given purpose. within the second stage, SmartCrawler accomplishes fast in-site excavating therefore on see most important affiliations with a flexible connection positioning. To dispense with inclination on going by some passing vital connections in shrouded net indexes, we have a tendency to define a affiliation tree info structure to accomplish a lot of in depth scope for a web site. Our check results on a meeting of delegate areas demonstrate the readiness and exactness of our planned crawler structure, that effectively recovers profound net interfaces from Brobdingnagian scale destinations and accomplishes higher harvest rates than completely different crawlers.

A cobalt-doping induced heterogeneous structure of MoS2-CoS2 grown on one-dimensional tubular carbon (ODTC) has been synthesized. The CoS2 nanoparticles can inhibit the free growth of MoS2 nanosheets and obtain MoS2-CoS2...

SnTe, emerging as an environment‐friendly alternative to conventional PbTe thermoelectrics, has drawn significant attention for clean energy conversion. Here, a high peak figure of merit (ZT) of 1.45 at 873 K in Ge/Bi codoped SnTe–AgBiTe2 alloys is reported. It is demonstrated that the existence of Ge, Bi, and Ag facilitate band convergence in SnTe, resulting in remarkable enhancement of Seebeck coefficient and power factor. Simultaneously, localized lattice imperfections including dislocations, point defects, and micro/nanopore structures are caused by incorporation of Ge, Bi, and Ag, which can effectively scatter heat carrying phonons with different wavelengths and contribute to an extremely low κL of 0.61 W m−1 K−1 in Sn0.92Ge0.04Bi0.04Te–10%AgBiTe2. Such high peak ZT is achieved by decouples electron and phonon transport through band modification and localized lattice engineering, highlighting promising solutions for advancing thermoelectrics.
