High-purity copper(Cu) with excellent thermal and electrical conductivity, is crucial in modern technological applications, including heat exchangers, integrated circuits, and superconducting magnets. The current purification process is mainly based on the zone/electrolytic refining or anion exchange, however, which excessively relies on specific integrated equipment with ultra-high vacuum or chemical solution environment, and is also bothered by external contaminants and energy consumption. Here we report a simple approach to purify the Cu foils from 99.9%(3N) to 99.99%(4N) by a temperature-gradient thermal annealing technique, accompanied by the kinetic evolution of single crystallization of *** success of purification mainly relies on(i) the segregation of elements with low effective distribution coefficient driven by grain-boundary movements and(ii) the high-temperature evaporation of elements with high saturated vapor *** purified Cu foils display higher flexibility(elongation of 70%) and electrical conductivity(104% IACS) than that of the original commercial rolled Cu foils(elongation of 10%, electrical conductivity of ~ 100% IACS). Our results provide an effective strategy to optimize the as-produced metal medium, and therefore will facilitate the potential applications of Cu foils in precision electronic products and high-frequency printed circuit boards.

Time reversal asymmetry and spatial anisotropy are considered two prerequisites for Brownian ratchet. An intriguing realization can be achieved by placing an asymmetric gear in the suspension of motile rod-like bacteria. Usually,alignment interactions caused by anisotropic collisions or hydrodynamics would boost the ratchet effect. Here, we are concerned with a perfectly isotropic system, i.e., symmetric gear immersed in a bath of spherical active Brownian particles. We find that, under certain conditions, kinetic symmetry-breaking arises spontaneously, i.e., the symmetric gear keeps rotating in one direction. Unexpectedly, such ratchet phenomenon does not rely on the direct many-particle interactions and moreover the introduction of alignment interaction would counterintuitively prevent it from happening! Further investigation reveals that such spontaneous symmetry-breaking phenomenon shares similarities with the equilibrium phase transition of the Ising *** results provide new insights and enhance our understanding of the fundamental aspects of active ratchet phenomena.

The classic cartoon “Calabash Brothers” describes a story of seven brothers born from a magic gourd uniting to defeat powerful enemies. In order to explore the secret of the magic gourd, several transition metals were used to synthesize metal silicates（CMSi） by planted gourd leaves（GLs） and then the C-MSi materials were used to fabricate supercapacitor electrodes and devices with superior electrochemical performance. By integrating theoretical calculations and experimental results, the supercapacitor electrodes and devices obtained from the combination of transition metals with amorphous carbon exhibit superior electrochemical performance. In detail, in the three-electrode system, the NaOH etched materials（C-MSi） exhibited better electrochemical performance(for instance, as for C-CdSi, 607 F g-1at 0.5 A g-1and the capacitance retention of 98.2% after 10,000cycles) than the unetched ones（i-C-MSi）. Hybrid supercapacitor（HSC） devices also achieve very excellent electrochemical properties. Take C-CdSi//AC as an example, the areal specific capacitance with 691 m F cm-2at 2 mA cm-2, the energy density with 5.04 Wh m-2at the power density of 22.2 W m-2and the cycle stability with 87.3% after 6,000 cycles. This approach is very versatile and was also applied to produce many hierarchically structured metal-silicate materials of other biomass precursors,including roots, vines, flowers, fruits and seeds of the planted gourds. Thus, it is a potential way to prepare transition metal silicates using biomaterials for the enhancement of electrochemical performance and improvement of energy storage and conversion. Also, this paper preliminarily reveals the secret of the magic gourd.
