The removal of acetylene impurities remains important yet challenging to the ethylene downstream industry. Current thermocatalytic semihydrogenation processes require high temperature and excess hydrogen guarantee complete conversion. For this reason, renewable electricity-based electrocatalytic over Cu-based catalysts is an attractive route compared energy-intensive processes. However, active Cu electrocatalysts still face competition from side reactions often overpotentials. Here, we...
Abstract Proton exchange membrane water electrolysers promise to usher in a new era of clean energy, but they remain formidable obstacle designing active and durable electrocatalysts for the acidic oxygen evolution reaction (OER). In this study, protonated iridium oxide embedded with single‐atom dispersed ruthenium atoms (H 3.8 Ir 1− x Ru O 4 ) that demonstrates exceptional activity stability oxidation is introduced. The single dopants favorably induce localized vacancies Ir─O lattice,...
We systematically investigated the reaction mechanism and effect of O2 on N2O reduction by NH3 over an Fe–Mordenite (MOR) catalyst. has no inhibitory reduction, selective catalytic (SCR) is superior to oxidation O2. found that SCR involves redox cycle Fe(III)–OH sites, with as first rate-determining step. Then activated at reduced Fe(II)–OH sites into NO/N or N2/O, reoxidizing sites. Next, NO formed in situ reacts adsorbed NH2 form NH2NO, which further decomposes N2 water. In addition, some...
We reveal a mechanism to enhance particle-matter interactions by exploiting the pseudo-Brewster effect of gain materials, presenting an enhancement at least four orders magnitude for light emission. This is enabled emergence unprecedented phase diagram that maps all phenomena free-electron transition radiation into three distinct phases in gain-thickness parameter space, namely, conventional, intermediate, and Brewster phases, when electron penetrates dielectric slab with modest finite...
Cherenkov radiation occurs only when a charged particle moves with velocity exceeding the phase of light in that matter. This mechanism creates directional emission at wide range frequencies and could facilitate development on-chip sources except for hard-to-satisfy requirement high-energy particles. Creating from low-energy electrons has no momentum mismatch free space is still long-standing challenge. Here, we report to overcome this challenge by exploiting combined effect interfacial...
Optical frequency combs have been widely used in spectrum analysis, coherent optical communication, and accurate distance measurement. We propose a straightforward method to improve the flatness of combs. First, we derived output signal for configuration cascaded MZM two PMs. Second, identified parameter value when was optimal after traversing different spaces. The conditions could be automatically determined from an existing sample dataset by using neural networks Bayesian optimization,...
Next-generation techniques for sustainable carboxylate production generate salts as the primary outcome. To circumvent costly conversion of to acids, we demonstrate aqueous (non-)Kolbe electrolysis process an alternative strategy downstream value-added chemicals. Upon revealing irreversible oxidation-induced charge transfer inhibition on graphite anode, propose anion intercalation mitigate stability problem induced by ever-increasing overpotential. In acetate decarboxylation, observe a high...
A series of Co exchanged zeolites with ZSM-5, BEA, MOR and USY structures were prepared investigated for N2O catalytic decomposition under identical reaction conditions. It is found that Co-zeolites different show dramatically activities, which could be attributed to various species formed in them. Co-ZSM-5, Co-BEA Co-MOR exhibit much higher activities than Co-USY catalysts, the predominant formation active isolated Co2+ ions ion exchange positions; while mainly exists as less oxides....
Abstract Transverse electric graphene plasmons are generally weakly confined in the direction perpendicular to plane. They featured by a skin depth δ , namely penetration of their evanescent fields into surrounding environment, much larger than wavelength λ free space (e.g., > 10 ). The weak spatial confinement transverse is now key drawback that limits practical applications. Here we report TE can be largely decreased down subwavelength scale < /10) negative refractive-index...
Abstract Facial expressions and movements, from a subtle ephemeral grimace, to vigorous rapid chewing, offer direct insights into the moment-to-moment change of neural physiological processes. Mice, with discernible facial responses evolutionarily conserved mammalian movement control circuits, provide an ideal model unravel link between underlying states. However, existing frameworks lack spatial or temporal resolution sensitively track all movements mouse face, due its small conical form...
