Abstract Rational design and synthesis of superior electrocatalysts for ethanol oxidation is crucial to practical applications direct fuel cells. Here, we report that the construction Pd-Zn dual sites with well exposure uniformity can significantly improve efficiency electro-oxidation. Through synthetic method control, on intermetallic PdZn nanoparticles, Pd-Pd Pd nanoparticles individual are respectively obtained same N-doped carbon coated ZnO support. Compared sites, display much higher...
Single-image super-resolution restores the lost structures and textures from low-resolved images, which has achieved extensive attention research community. The top performers in this field include deep or wide convolutional neural networks, recurrent networks. However, methods enforce a single model to process all kinds of structures. A typical operation is that certain layer based on ones recovered by preceding layers, ignoring characteristics image textures. In paper, we believe...
This paper reviewed the 3rd NTIRE challenge on single-image super-resolution (restoration of rich details in a low-resolution image) with focus proposed solutions and results. The had 1 track, which was aimed at real-world single image problem an unknown scaling factor. Participants were mapping images captured by DSLR camera shorter focal length to their high-resolution longer length. With this challenge, we introduced novel dataset (RealSR). track 403 registered participants, 36 teams...
Utilizing heterogeneous catalysts to overcome obstacles for homogeneous reactions is fascinating but very challenging owing the difficult fabrication of such based on character target reactions. Herein, we report a Al3+ doping strategy construct single-atom Cu MgO nanosheets (Cu1/MgO(Al)) boosting free-radical hydrophosphinylation alkenes. dopants in bring about abundant Mg2+ vacancies stabilizing dense independent atoms (6.3 wt %), while aggregated nanoparticles are formed without (Cu/MgO)....
This paper reviews the NTIRE 2023 challenge on image super-resolution (×4), focusing proposed solutions and results. The task of (SR) is to generate a high-resolution (HR) output from corresponding low-resolution (LR) input by leveraging prior information paired LR-HR images. aim obtain network design/solution capable produce high-quality results with best performance (e.g., PSNR). We want explore how high we can achieve regardless computational cost model size FLOPs) data. track was measure...
Single-atom (SA) catalysts have attracted broad attention due to their distinctive catalytic properties in diverse reactions. Increasing the unsaturated coordination sites of active centers is a valid and challenging approach improve performance such catalysts. Herein, we report an oxide compounding strategy decrease N number SA Cu catalyst by reducing thickness N-doped carbon carrier with lower density atoms. The more structure can achieve transfer hydrogenation alkynes good activity...
Tuning electronic characteristics of metal–ligand bonds based on reaction pathways to achieve efficient catalytic processes has been widely studied and proven be feasible in homogeneous catalysis, but it is scarcely investigated heterogeneous catalysis. Herein, we demonstrate the regulation configuration Ir–O an Ir single-atom catalyst according borane activation mechanism. Ir1/Ni(OH)x are found more electron-poor than those Ir1/NiOx. Despite mild solvent-free conditions ambient temperature,...
Hydrodeoxygenation is the key technology for realizing conversion of biomass into high value-added chemicals, but usually encounters low efficiency and harsh conditions due to rich electron density strong C-O bonds O-containing groups. Herein, an efficient catalyst precisely constructed with abundant acidic O dopants well-exposed oxidized Pd centers hydrodeoxygenation vanillin. Through a tannic acid-assisted strategy, it on alumina that electron-deficient species doped as ether types in...
Blind image super-resolution (BISR) aims to construct high-resolution from low-resolution (LR) that contains unknown degradation. Although the previous methods demonstrated impressive performance by introducing degradation representation in BISR task, there still exist two problems most of them. First, they ignore characteristics different regions when generating representation. Second, lack effective supervision on generation both and result. To solve these problems, we propose dual circle...
Abstract In this study, a computational fluid dynamics mathematical model has been developed for catalytic fast pyrolysis (CFP) of biomass based on multiphase flow, transfer process, and reactions in bubbling fluidized bed reactor. The the inter‐phase momentum energy processes are modeled with Eulerian formulas, representing flows gases solids (catalyst biomass) within CFP described by using two‐stage, semi‐global model. Specified secondary tar cracking which considers both intrinsic...
Precisely controlling the selectivity of nanocatalysts has always been a hot topic in heterogeneous catalysis but remains difficult owing to their complex and inhomogeneous catalytic sites. Herein, an effective strategy regulate chemoselectivity Pd for selective hydrogenation reactions by inserting single-atom Zn into nanoparticles is reported. Taking advantage tannic acid coating-confinement strategy, small-sized with inserted are obtained on O-doped carbon-coated alumina. Compared pure...
In this paper, we propose a temporal group alignment and fusion network to enhance the quality of compressed videos by using long-short term correlations between frames. The proposed model consists intra-group feature (IntraGFA) module, inter-group (InterGFF) enhancement (FE) module. We form pictures (GoP) selecting frames from video according their distances target enhanced frame. With grouping, composed GoP can contain either long- or short-term correlated information neighboring design...
