Developing CO-tolerant Pt-based catalysts for the hydrogen oxidation reaction (HOR) is critical commercialization of fuel cells and thus receiving increasing interest. Although it known that weakening CO adsorption on Pt can improve tolerance, efficient strategies are still needed. Inspired by theoretical simulations, we propose here a cascade strategy to synergistically mitigate electron back-donation 5d → 2π* introducing single-atomic Fe–N–C substrate alloying, which significantly boosts...
Contact electrification (CE) involves a complex interplay of physical interactions in realistic material systems. For this reason, scientific consensus on the qualitative and quantitative importance different mechanisms CE remains formidable task. The mechanism at water/polymer interface is crucial challenge owing to poor understanding charge transfer atomic level. First-principle density functional theory (DFT), used present work, proposes new paradigm address CE. Our results indicate that...
Abstract Uncontrolled Zn dendrites and undesirable side reactions such as self‐corrosion hydrogen evolution reaction (HER) remain major challenges for the further development of aqueous batteries (AZBs).

Summary Iron (Fe) deficiency is one of the most common micronutrient deficiencies limiting crop production globally, especially in arid regions because decreased availability iron alkaline soils. Sweet potato [ Ipomoea batatas (L.) Lam.] grows well and tolerant to Fe deficiency. Here, we report that transcription type I H + ‐pyrophosphatase (H ‐ PP ase) gene Ib VP 1 sweet plants was strongly induced by auxin hydroponics, improving acquisition via increased rhizosphere acidification...
We use molecular dynamics simulations (MD) to study piezoelectric properties of hexagonal boron nitride nanosheets (BNNS) and reveal how depend on size shape. first analyze the macroscopic shape affects full 2D structure symmetry its tensor. In particular, we demonstrate that a (rectangular)-shaped BNNS belongs 6̄m2 (monoclinic m) point group. Our simulation results show constants strongly shape, in agreement with structure, but are nearly independent size. The present provides detailed...

Due to their low cost, interference resistance, and concealment of vision sensors, vision-based landing systems have received a lot research attention. However, sensors are only used as auxiliary components in visual because limited accuracy. To solve the problem inaccurate position estimation vision-only during landing, novel data closed-loop pose-estimation algorithm with an implicit neural map is proposed. First, we propose method which estimate UAV pose based on runway’s line features,...
Abstract An Early Devonian (Pragian) plant, Hueberia zhichangensis gen. et sp. nov., is described from the Posongchong Formation, Wenshan district of southern Yunnan, China. It characterized by stems < 2 mm wide and closely helically‐arranged enations. A creeping habit suggested due to K‐type branching. No fertile organs are preserved. nov. resembles Drepanophycus Kaulangiophyton, but much smaller has a more regular phyllotaxy. Key words: Plant fossilstaxonomyEarly DevonianPosongchong FormationChina
Dear Editor, This work investigates the issue of facial cartoonlization under condition lacking training data. We propose a domain-guided model (DGM) to realize for different kinds faces.
