Alloying is an important strategy for the design of catalytic materials beyond pure metals. The conventional alloy catalysts however lack precise control over local atomic structures active sites. Here we report on investigation active-site ensemble effect in bimetallic Pd-Au electrocatalysts CO2 reduction. A series Pd@Au are synthesized by decorating Au nanoparticles with Pd controlled doses, giving rise to surfaces containing ensembles various sizes. Their activity electroreduction CO...
Modern functional adhesives have attracted considerable attention due to their reversible adhesion capacities and stimuli-responsive behavior. However, for modern adhesives, polymeric structures were highly necessary realize behaviors. Supramolecular from low-molecular-weight monomers rarely recognized. Compared with adhesive materials, it remains challenging supramolecualr materials tough on wet surfaces or even under water. In this study, a new supramolecular consisting of was successfully...
Active and highly stable electrocatalysts for oxygen evolution reaction (OER) in acidic media are currently high demand as a cleaner alternative to the combustion of fossil fuels. Herein, we report Co-doped nanorod-like RuO2 electrocatalyst with an abundance vacancies achieved through facile, one-step annealing Ru-exchanged ZIF-67 derivative. The compound exhibits ultra-high OER performance media, low overpotential 169 mV at 10 mA cm−2 while maintaining excellent activity, even when exposed...
Development of platinum group metal (PGM)-free and iron-free catalysts for the kinetically sluggish oxygen reduction reaction (ORR) is crucial proton-exchange membrane fuel cells. A major challenge their insufficient performance durability in electrode assembly (MEA) under practical hydrogen-air conditions. Herein, we report an effective strategy to synthesize atomically dispersed Mn–N–C from environmentally benign aqueous solution, instead traditional organic solvents. This innovative...
Ethanol is a green, sustainable, and high-energy-density liquid fuel that holds great promise for direct cells (DLFCs). However, it remains highly challenging to develop electrocatalysts selectively promote the C–C bond scission ethanol oxidation reaction (EOR). Here, we report facile synthesis of PtIr alloy core–shell nanocubes (NCs) with Ir-rich shells as effective EOR electrocatalysts. We find (100)-exposed Pt38Ir NCs one-atom-thick skin exhibit unprecedented activity, high CO2...
Adhesive materials that are resistant to low temperatures have wide applications in daily life, scientific research, and industry. Currently, the overwhelming majority of low-temperature-resistant adhesives traditional polymer systems. In this study, a new strategy was developed obtain strong long-lasting adhesion effects from low-molecular-weight at temperatures. The introduction water molecules formation hydrogen bonds not only triggered supramolecular polymerization but also endowed...
Although the gelation process and lower critical solution temperature (LCST) behavior are well acknowledged in polymer systems, low-molecular-weight gelators (LMWGs) rarely display LCST during supramolecular gelation. Herein, we report an LMWG system with LCST-type thermoresponsiveness LCST-triggered process. Temperature plays a crucial role this system, not only affecting phase separation but also triggering The backbones (three-dimensional structures) of resulting hydrogel hierarchical...
The catalytic performance of Molybdenum disulfide (MoS 2 ) has been still far from that Pt‐based catalysts for inadequate active sites and sluggish electron transfer kinetics. Through engineering the interface between MoS ‐based materials supported substrates, hybrid Ru‐doped on carbonized lignin (CL) is designed prepared as efficient catalyst hydrogen evolution reaction (HER). CL substrate not only facilitates growth nanoflowers, but also promotes transfer. Ru doping increases greatly HER....
This paper compares two estimators—the Border Approach and an Instrumental Variable (IV) estimator—using a unified framework where identifying variation arises from “preference externalities,” following the intuition in Waldfogel (2003) . We highlight dimensions favor of IV approach. First, econometric model data-generating process reveals that border approach requires set identification assumptions are not easily satisfied practice: ignorance some payoff-relevant information conflicting...
Abstract By integrating Fresnel zone plate (FZP) with Pancharatnam–Berry (PB) phase, spin-controlled compact metalenses for multidimensional focusing are demonstrated. The position of the focal point can be modulated transversally and longitudinally by changing PB phase profiles encoded into FZP adjusting spin state incident circularly polarized (CP) waves. Concretely, combining an amplitude-type (AFZP) linear or spherical creates two points orthogonal states in transversal longitudinal...
Rechargeable aqueous zinc metal-based batteries present a promising alternative to conventional lithium-ion due their lower operating potentials, higher capacities, intrinsic safety, cost-effectiveness, and environmental sustainability. However, the use...
The electrochemical production of hydrogen peroxide is enjoying increasing attention by endowing a promising alternative to the traditional complex and energy-intensive anthraquinone process. Engineering efficient electrocatalysts with desirable activity, selectivity, stability toward H2O2 electrocatalysis have achieved great progress yet are still challenging. Currently, atomically dispersed Pt atoms on metal been evidenced as one most candidates for their remarkable catalytic activity...
Crystalline Si nanowire (SiNW) springs, produced via a low temperature (<350 °C) thin film technology, are ideal building blocks for stretchable electronics. Herein, novel cyclic crystallographic‐index‐lowering self‐turning and twin dynamics is reported, during tin‐catalyzed in‐plane growth of SiNWs, which results in periodic zigzag SiNW without any external parametric intervention. More interestingly, unique twin‐reflected interlaced crystal‐domain structure has been identified the first...
We found that TC7 not only self-assembles into one-dimensional supramolecular aggregates in chloroform, but also forms cross-linked polymers via host-guest complexation between benzo-21-crown-7 and secondary ammonium salts. Compared with linear polymers, soft long viscous fibers were pulled out from a concentrated solution of as result higher viscosity lower diffusion coefficients.
