A detailed study of the polarization and depolarization behavior 7:65:35 8:65:35 lead lathanum zirconate titanate transparent ceramics under dc bias constant heating rates has been carried out. The dielectric permittivity exhibits a new anomaly near 0 °C in freshly thermally depoled samples which is associated with buildup macrodomains development remanent polarization. From continuity dispersive behaviors it suggested that change at so-called α–β transition Td not conventional phase change,...

In materials of all types, hysteresis and toughness are usually correlated. For example, a highly stretchable elastomer or hydrogel single polymer network has low toughness. The is commonly toughened by introducing sacrificial bonds, but breaking possibly reforming the bonds causes pronounced hysteresis. this paper, we describe principle that disrupt toughness-hysteresis correlation, achieving both high We demonstrate fabricating composite two constituents: matrix elastic modulus, fibers...

Inspired by the efficient fog collection on cactus spines, conical copper wires with gradient wettability are fabricated through electrochemical corrosion and subsequent chemical modification. These dual-gradient wires’ fog-collection ability is demonstrated to be higher than that of pure hydrophobic surfaces or hydrophilic surfaces, underlying mechanism also analyzed. As a service our authors readers, this journal provides supporting information supplied authors. Such materials peer...

Significance In the past decades, a vast body of experimental and theoretical work has been undertaken to investigate molecular level mechanism underlying heterogeneous ice nucleation. However, understanding nucleation is still far from satisfactory. Antifreeze proteins (AFPs) are endowed with unique ability control freezing. Our research reveals exact effect AFPs on at level, which correlates surface chemistry topography different faces AFPs. We also emphasize critical role for...

For a hydrogel coating on substrate to be stable, covalent bonds polymerize monomer units into polymer chains, crosslink the chains network, and interlink network substrate. The three processes-polymerization, crosslinking, interlinking-usually concur. This concurrency hinders widespread applications of coatings. Here principle is described create paints that decouple polymerization from crosslinking interlinking. Like common paint, paint divides labor between maker user. formulates by...

Sr‐doped PbZrO 3 antiferroelectric (AFE) thin films have been fabricated on the platinum‐buffered silicon substrates via sol–gel technique. The temperature‐dependent dielectric properties results indicated that AFE phase was stabilized for Sr‐modified with a Curie temperature of 251°C. recoverable energy density and efficiency were enhanced by doping strontium. Compared pure films, performance against fatigue also improved greatly.

Temperature-driven switching of water adhesion is realized on a novel n-paraffinswollen organogel by thermally controlling the transition air/liquid/solid (ALS/ALLS) systems via phasechange process n-paraffin.

With the increasing world population and rapid development of global industry, clean water is becoming scarcer scarcer. Means translating latent in fog to dominant available water, i.e., collection, therefore becomes highly desirable. Previously, it was demonstrated that cactus O. Microdasys has an integrated collection system arising from evenly distributed clusters spines trichomes on stem. Here, reported intersite stem densely covered with cones, which are also capable collecting...

The emergence of stretchable electronics and its potential integration with textiles have highlighted a challenge: Textiles are wearable washable, but electronic devices not. Many conductors been developed to enable active textiles, little has done make them washable. Here we demonstrate new class that can endure wearing washing conditions commonly associated textiles. Such conductor consists hydrogel, dissolved hygroscopic salt, butyl rubber coating. salt enables ionic conduction matches...
