Article Abstract
Here, lamellar confinement strategy is introduced for "sheet-to-nanocrystals (NCs)" conversion within a 2D-SiO envelope, which constructs a catalytic nanocartridge holding a platoon of isolated and in-plane-aligned ultrasmall Ni-NCs, performing as a robust and coking-resistant catalytic system for dry reforming of methane. Overcoming the problem of unavoidable bulk crystal growth from multiple sheets-stack or sheet-on-open-support, silica bilayer-encasing tightly clamps the atomic-thin Ni(OH) -nanosheet during thermal conversion and further hinders the migratory fusion of the resultant Ni-NCs. Upon heating-cooling cycle, the flapping silica envelope clutches the Ni-NCs like "eggs in a carton," subsequently, ensuring their thermal stability. Owing to the unique 2D-enveloped rigid architecture, Ni-NCs can circumvent sintering and coke deposition while tolerating the high temperatures (>700 °C) for long operation (>100 h), affording high conversions to syngas.

Chemical absorption of carbon dioxide using monoethanolamine (MEA) is a well-established method for postcombustion CO capture. In this study, we aimed to integrate (1) the MEA-based CO capture with the regeneration of MEA using calcium-based mineralization, followed by (2) direct utilization of captured CO to form syngas via a calcium looping-based dry reforming of methane (CaL-DRM), an interfacial catalytic process. The results show that room-temperature CO capture-MEA regeneration was achievable by using calcium-based mineralization.

This study aims to investigate the regulatory effect of exogenous melatonin (MT) on the growth and development of cucumbers subjected to salt stress. Using the XinTaiMiCi material and indoor pot culture method, seven treatments were set up: control group (CK), T0 (salt treatment group, 150 mM S + 0 μM MT), T1 (150 mM S + 25 μM MT), T2 (150 mM S + 50 μM MT), T3 (150 mM S + 100 μM MT), T4 (150 mM S + 150 μM MT), and T5 (150 mM S + 200 μM MT). Changes in plant height, stem diameter, leaf area, relative chlorophyll content, antioxidant enzyme activity, reactive oxygen species content, and osmotic adjustment substance content in cucumber seeds and seedlings under different treatments were studied, and a correlation analysis of these indicators was conducted.

In neural biointerfacing technologies, mitigating the mismatch in mechanical and impedance attributes between neural tissues and bioelectronics remains a central challenge for achieving high-efficacy neuromodulation. Here, full-hydrogel bioelectronics that demonstrate superior mechanical compliance and impedance matching with 3D peripheral nerves, allowing for low-voltage vagus nerve stimulation, are reported. By precisely tuning the dimensional parameters through 3D printing, the hydrogel bioelectronics, initially in a 2D planar form in a dehydrated state, can curl spontaneously around nerves and form a seamless interface.

Dry reforming of methane (DRM, CH+CO→2CO+2H) involves production of CO and H using two kinds of greenhouse gases, CH and CO, without requiring an expensive and complicated gas separation process. Using a developed specimen holder, we observed the Ni nanoparticles on AlO supports during DRM catalysis through in situ transmission electron microscopy and electron energy loss spectroscopy by tracking each individual nanoparticle to elucidate the structural and chemical features of the working catalyst under practical conditions. The average value of the Ni L/L intensity ratio, which relates to the valence state (i.

The paper deals with thermodynamic analysis of CH reforming with different oxidants (CO, HO, and O) in DRM and TRM processes. Both processes producing syngas use simultaneously two components of greenhouse gases as feedstock: CO and CH. Statistical methods (Response Surface Methodology, Ridge Analysis) were used to analyze the effects of temperature, pressure, and molar ratio of oxidants to methane on feedstock conversion, yield and selectivity of products, H and CO, and the H/CO ratio characterizing the suitability of syngas for various syntheses.
