Identification of mitophagy-related genes and analysis of immune infil
Introduction Atherosclerosis is a complex and chronic inflammatory disease of the arteries, characterized by the formation of atherosclerotic plaques.1 Its pathogenesis involves a combination of endothelial injury, lipid accumulation, and dysregulated immune responses that promote plaque development within the arterial wall.
Diurnal asymmetry of surface albedo in a semi‐arid grassland over the China's Loess Plateau
1 INTRODUCTION Surface albedo (α) is defined as the ratio of ground-reflected solar radiation to incident global shortwave (SW) radiation (0.3–3.0 μm), which is a key physical quantity for regulating the surface energy budget in Earth–atmospheric system and affecting regional and global climate (Betts & Ball, 1997; Dickinson, 1983; Fan et al., 2015; Zheng et al., 2017).

CO2 chemisorption and activation on carbon nitride with less amino groups boost CO2 photoreduction
CO2 chemisorption and activation on carbon nitride with less amino groups boost CO2 photoreduction† CO2 chemisorption and activation are two crucial factors that can significantly impact the overall CO2 conversion efficiency. However, achieving effective modulation of these processes in metal-free photocatalysts has proven to be challenging. In this study, we present a novel approach for activating CO2 molecules by selectively removing some amino groups at the boundary of carbon nitride (CN).

Zeolite encapsulated copper(II) complexes with NNO-tridentate Schiff base ligands: catalytic activity towards methylene blue (MB) degradation in a near neutral condition
Zeolite encapsulated copper(II) complexes with NNO-tridentate Schiff base ligands: catalytic activity towards methylene blue (MB) degradation in a near neutral condition Three novel copper Schiff base complexes L1Cu(OAc)-L3Cu(OAc) bearing NNO tridentate ligands have been synthesized and were successfully entrapped into the zeolite.
Research on Hydrogen-Fueled Turbojet Engine Control Method Based on Model-Based Design
1. Introduction With the growing global demand for sustainable aviation, hydrogen-fueled turbojet engines are gaining attention in the aviation industry due to their low-carbon, efficient, and environmentally friendly characteristics [1]. This is mainly due to the fact that the main products of hydrogen fuel combustion are stream and trace amounts of nitrogen oxides (NOx), which have a significantly lower impact on the environment compared to conventional fuels [2,3].

Transient Modeling and Performance Analysis of Hydrogen-Fueled Aero Engines
Abstract : With the combustor burning hydrogen, as well as the strongly coupled fuel and cooling system, the configuration of a hydrogen-fueled aero engine is more complex than that of a conventional aero engine. The performance, and especially the dynamic behavior of a hydrogen-fueled aero engine, need to be fully understood for engine system design and optimization. In this paper, both the transient modeling and performance analysis of hydrogen-fueled engines are presented.
