Chirality plays a significant role in the physical properties and biological functions of many materials, e.g., climbing tendrils twisted leaves, which exhibit chiral growth. However, mechanisms underlying growth materials remain unclear. In this paper, we investigate how Towel Gourd achieve their Our experiments reveal that have hierarchy chirality, transfers from lower levels to higher. The change helical angle cellulose fibrils at subcellular level induces an intrinsic torsion tendrils,...
Bulk metallic glasses exhibit high strength and large elastic strain limit but have no tensile ductility. However, bulk glass composites reinforced by in-situ dendrites possess significantly improved toughness at the expense of limit. Here, we report a composite with strong strain-hardening capability It was found that, plastic predeformation, can both under tension. These unique mechanical properties are attributed to reversible B2↔B19' phase transformation plastic-predeformation-induced...
Abstract Recent progress on the signatures of pressure-induced high-temperature superconductivity in Ruddlesden–Popper (RP) nickelates (La n +1 Ni O 3 ) has attracted growing interest both theoretical calculations and experimental efforts. The fabrication high-quality single-crystalline RP nickelate thin films is critical for possible reducing superconducting transition pressure advancing applications microelectronics future. In this study, we report observations an active phase induced by...
Cereal storage proteins are major nitrogen sources for humans and livestock. Prolamins the most abundant protein in cereals. They deposited into bodies (PBs) seed endosperm. The inner structure mechanism prolamin PBs is poorly understood. Maize opaque10 (o10) a classic opaque endosperm mutant with misshapen PBs. Through positional cloning, we found that O10 encodes novel cereal-specific PB protein. Its middle domain contains seven-repeat sequence responsible its dimerization. C terminus...
Abstract The design of ductile heterogeneous metallic glasses (MGs) with enhanced deformability by purposely controlling the shear-band dynamics via modulation atomic-scale structures and local stress states remains a significant challenge. Here, we correlate changes in atomic structure when cooling to cryogenic temperature observed improved shear stability. atomic-level structural elastic heterogeneities related nonaffine thermal contraction short-range order (SRO) medium-range (MRO) change...

We synthesized polycrystalline La3Ni2O7 samples by using the sol-gel method without post-annealing under high oxygen pressure, and then measured temperature-dependent resistivity various hydrostatic pressures up to 14.5 GPa in a cubic anvil cell apparatus. find that density-wave-like anomaly is progressively suppressed with increasing pressure drop corresponding onset of superconductivity emerges at as low 7 GPa.

A survey of published literature reveals a difference in the density amorphous and crystalline solids (organic inorganic) on order 10%–15%, whereas for metallic alloys, it is found to be typically less than 5%. Standard geometric models atomic packing can account polymeric inorganic glasses without requiring changes interatomic separations (bond lengths). By contrast, relatively small between glassy metals (and alloys) implies variations due merging orbitals giving rise reduced volumes. To...
The recent discovery of superconductivity in La$_3$Ni$_2$O$_{7-\delta}$ with a transition temperature $T_c$ close to 80 K at high pressures has attracted significant attention, due particularly possible density wave (DW) occurring near the superconducting dome. Identifying type DW order is crucial for understanding origin this system. However, owing presence La$_4$Ni$_3$O$_{10}$ and other intergrowth phases samples, extracting intrinsic information from La$_3$Ni$_2$O$_7$ phase challenging....
