The cleavage of C–O bonds presents the crucial step for realizing depolymerization lignin. Herein, we report that Ni nanoparticles (NiNPs) supported on CeO2 with oxygen vacancies (Ov) show high activity and selectivity in hydrogenolysis diphenyl ether (DPE, a lignin model compound), while single-site (SSNi) is nearly inactive reaction. Temperature-programmed desorption (TPD) demonstrates both DPE H2 can be adsorbed activated NiNPs. Density functional theory (DFT) calculation further...
Abstract Upgrading of polyethylene terephthalate (PET) waste into valuable oxygenated molecules is a fascinating process, yet it remains challenging. Herein, we developed two‐step strategy involving methanolysis PET to dimethyl (DMT), followed by hydrogenation DMT produce the high‐valued chemical methyl p‐methyl benzoate (MMB) using fixed‐bed reactor and Cu/ZrO 2 catalyst. Interestingly, discovered phase structure ZrO significantly regulates selectivity products. Cu supported on monoclinic...
Masked image modeling (MIM) has attracted much research attention due to its promising potential for learning scalable visual representations. In typical approaches, models usually focus on predicting specific contents of masked patches, and their performances are highly related pre-defined mask strategies. Intuitively, this procedure can be considered as training a student (the model) solving given problems (predict patches). However, we argue that the model should not only problems, but...
Self-supervised learning (SSL) has made remarkable progress in visual representation learning. Some studies combine SSL with knowledge distillation (SSL-KD) to boost the performance of small models. In this study, we propose a Multi-mode Online Knowledge Distillation method (MOKD) self-supervised Different from existing SSL-KD methods that transfer static pre-trained teacher student, MOKD, two different models learn collaboratively manner. Specifically, MOKD consists modes: self-distillation...
Farmland changes have a profound impact on agricultural ecosystems and global food security, making the timely accurate detection of these crucial. Remote sensing image change provides an effective tool for monitoring farmland dynamics, but existing methods often struggle with high-resolution images due to complex scenes insufficient multi-scale information capture, particularly in terms missed detections. Missed detections can lead underestimating land changes, which affects key areas such...
Abstract We propose an effective surface plasmon resonance system designed to achieve both negative and positive Goos-Hanchen shifts in reflected light. This comprises a metal film underlying medium, where the real part of permittivity medium must be less than unity. Surface polaritons can excited at lower when light is incident from air onto upper metal. The excitation leads exploration shift (G-HS). Control over (G-HS) investigated via wavelength magnitude G-HS strongly dependent on...

Mobile IP is a solution for mobility support in the global Internet. However, it suffers from long handoff delay. Many solutions have been proposed to reduce delay of IP. Among these solutions, Fast Handovers IPv6 (FMIPv6) and Hierarchical (HMIPv6) are actively developed by Internet Engineering Task Force future networks. A majority research on performance analysis latency either adopts simulation approach or based experimental testbeds. This paper focuses analytical modeling two fast...
Wireless mesh networks (WMNs) have recently emerged to be a cost-effective solution support large-scale wireless Internet access. One important component of realizing WMNs is mobility management. Although management has been extensively studied in cellular and Mobile IP networks, these schemes can cause significant performance degradation when directly applied WMNs. In this paper, study handoffs IEEE 802.11-based hybrid conducted. Since no existing handoff are specifically designed for...
