Engineering the adsorption of molecules on active sites is an integral and challenging part for design highly efficient transition-metal-based catalysts methanol dehydrogenation. A Mott-Schottky catalyst composed Ni nanoparticles tailorable nitrogen-doped carbon-foam (Ni/NCF) thus tunable energy presented selective dehydrogenation gas-phase to hydrogen CO even under relatively high weight hourly space velocities (WHSV). Both theoretical experimental results reveal key role rectifying contact...
Abstract Dissipative self-assembly, which requires a continuous supply of fuel to maintain the assembled states far from equilibrium, is foundation biological systems. Among variety fuels, light, original natural dissipative fundamentally important but remains challenge introduce into artificial self-assemblies. Here, we report an self-assembly system that constructed light-induced amphiphiles. Such supramolecular assembly easily performed using protonated sulfonato-merocyanine and chitosan...
Dissipative self-assembly, one of fundamentally important out-of-equilibrium self-assembly systems, can serve as a controllable platform to exhibit temporal processes for various non-stimulus responsive properties. However, construction light-fueled dissipative structures with transformable morphology modulate non-photoresponsive properties remains great challenge. Here, we report light-activated photodeformable system in aqueous solution metastable fluorescent palette. Zwitterionic...
The discharge of Fukushima radioactively contaminated water into the Pacific Ocean started in August 2023, posing comprehensive threats to marine ecosystems and human health globally. This study introduces Contaminated Water Risk Factor (FCWRF), which integrates three components─radionuclide diffusion, bioaccumulation, global seafood trade─to evaluate spatiotemporal distribution risks based on actual practices. Results suggest that exceeding 2 orders magnitude beyond baseline will be...
Polymers with broad infrared emission and negligible solar absorption have been identified as promising radiative cooling materials to offer a sustainable energy-saving venue. Although practical applications desire color for visual appearance, the current coloration strategies of polymer-based are constrained by material, cost, scalability. Here, we demonstrate universally applicable strategy nanoimprinting. By modulating light interference periodic structures on polymer surfaces, specular...
The exploitation of metal-free organic polymers as electrodes for water splitting reactions is limited by their presumably low activity and poor stability, especially the oxygen evolution reaction (OER) under more critical conditions. Now, thickness a cheap robust polymer, poly(p-phenylene pyromellitimide) (PPPI) was rationally engineered an in situ polymerization method to make polymer available first time flexible, tailorable, efficient, ultra-stable oxidation over wide pH range. PPPI...
Used paper was converted on a large scale to multifunctional graphene-tethered carbon fiber composite (GCCP) with novel “carbon tree” subunit structure.
A previously reported cobalt complex featuring a tetraimidazolyl-substituted pyridine chelate is an active water oxidation electrocatalyst with moderate overpotential at pH 7. While this decomposes rapidly to less-active species under electrocatalytic conditions, detailed electrochemical studies support the agency of initial molecular catalyst. Cyclic voltammetry measurements confirm that imidazolyl donors result in more electron-rich Co center when compared previous pyridine-based systems....
Complex structures from nanoparticles are found in rocks, soils, and sea sediments but the mechanisms of their formation poorly understood, which causes controversial conclusions about genesis. Here we show that graphene quantum dots (GQDs) can assemble into complex driven by coordination interactions with metal ions commonly present environment serve a special role Earth's history, such as Fe3+ Al3+ . GQDs self-assemble mesoscale chains, sheets, supraparticles, nanoshells, nanostars....

Abstract This study reports the effect of polydopamine bionic coating and γ‐methacryloxypropyltrimethoxysilane (KH570) composite modified polyacrylonitrile (PAN) fiber as a secondary modifier on performance styrene‐butadiene‐styrene (SBS) asphalt. Dynamic shear rheometer test indicated complex modulu, storage modulus, loss modulus PAN (KD‐PAN) incorporated SBS asphalt was increased by 12.4, 20.5, 11.2%, respectively compared with PAN/SBS The master curve G * fiber/SBS shows that deformation...

Molecular electrocatalysts show promise for energy-relevant multielectron transformations due to their rationally tunable activity and selectivity from systematic ligand modifications. However, surface-immobilized molecular electrocatalytic systems are typically limited by low per geometric surface area compared traditional solid-state analogues because of lower active site coverage. Many existing methods increasing coverage through the formation multilayer films based on radical-coupling or...

We present a new way of understanding the spectral behavior Fabry–Perot-type trilayer stack for subtractive structural color based on temporal coupled mode analysis. This cavity-based analysis is able to fit reflection spectra feature and predict chromaticity well even without taking material dispersion into account. To produce most chromatic color, this reveals that matching absorptive radiative decay rates while both being maximized key, which leads broad highest absorption peak. Inclusion...
In this paper, we propose a generalized Kretschmann configuration that employs metagrating to replace the prism, realizing polarization-controlled efficient and unidirectional surface plasmon polariton (SPP) excitation. This dielectric phase gradient on top of silica substrate is designed deflect incident light, which subsequently launches SPP wave by means momentum matching metal film coated bottom surface. A series metagratings enable excitation circularly or linearly polarized light. The...

Abstract Metal halide perovskites show promise for next-generation light-emitting diodes, particularly in the near-infrared range, where they outperform organic and quantum-dot counterparts. However, still fall short of costly III-V semiconductor devices, which achieve external quantum efficiencies above 30% with high brightness. Among several factors, controlling grain growth nanoscale morphology is crucial further enhancing device performance. This study presents a engineering methodology...
Abstract Iridescent color-shift pigments have been used in some industrial applications, e.g., for cosmetics and packaging. To achieve environmental-friendly lasting color, thin-film interference is to generate structural color. By maximizing the refractive index (RI) difference between thin films (i.e., using an ultralow RI film), super-iridescent color can be produced. While lowest of a naturally occurring solid dielectric close 1.37 MgF 2 ), we synthesized highly porous SiO aerogel...
