Numerical Analysis of Sand-Induced Erosion in a Transonic Axial Compressor Rotor Under Varying Particle Sizes

Xiaowen Xuan, Jichao Li, Shuzi Yang, Caifeng Zhang et autres

Abstract During operation in sand-laden environments, aero-engine compressor blades suffer severe localized erosion, leading to progressive degradation of compressor stage performance over the engine service life. This issue is particularly critical for high-speed transonic compressor rotors. In this study, the erosion behavior …

Comparative Study on the Skin-Tactile Performance of UV Excimer-Cured and UV Varnish Coatings on Primer-Treated Inkjet-Printed Melamine-Faced Panels

Ruijuan Sang, Yongchang Pan, Caifeng Zhang

Driven by the high-end furniture industry’s demand for skin-tactile decorative boards, UV inkjet printing shows potential for wood-based surface finishing. Using primer-treated inkjet-printed melamine-faced panels, this study compared traditional UV varnish coatings with different thicknesses and UV curing intensities and 254 nm …

Influence of Aerodynamic Probes for Measuring Distorted Inflow on the Performance in a High-Speed Axial Flow Fan

Caifeng Zhang, Wei Zhang, Boning Fan, C Liang et autres

Abstract Experimental evaluation of aero-engine compressor performance under distorted inflow conditions is clearly specified in airworthiness standards. Generally, to quantify the distortion intensity, six to eight multihole comb pneumatic probes were experimentally used to capture the circumferentially distorted flow field. Although the …

Integrating bulk RNA-seq and ScRNA-seq to identify manganese metabolism-related subtypes and immunoregulatory mechanisms in liver hepatocellular carcinoma

C H Liu, Wenqi Zhang, Wenzi Luo, Caifeng Zhang et autres

Liver hepatocellular carcinoma (LIHC) is an aggressive cancer associated with chronic liver disease, necessitating better biomarkers and therapies. Manganese, an essential trace element, regulates tumor development. Data from TCGA and GEO databases were analyzed to identify manganese metabolism-related genes (MMRGs). LIHC samples …

SEMA5B depletion suppresses cell proliferation and glycolysis by downregulating VDAC2 expression in esophageal squamous cell carcinoma

Caifeng Zhang, Lanfang Zhang, Xiaoling Zhang, Lijun Meng et autres

Although Semaphorin 5B (SEMA5B) has been reported to be involved in tumor progression, the underlying mechanisms in esophageal squamous cell carcinoma (ESCC) are still largely unknown. In this study, we found that SEMA5B gene was significantly upregulated in both ESCC samples and …

Theoretical Elucidation of Manganese(I)–Pincer Catalyzed α-Alkylation of Sulfones with Alcohols

Rui‐Ping Huo, Xiang Zhang, Kai‐Xin Xie, Caifeng Zhang

The manganese(I)-pincer catalyzed α-alkylation of sulfones with alcohols offers an efficient and sustainable C-C coupling strategy, though its mechanistic details and selectivity remain poorly understood. In this study, we employ density functional theory (DFT) to elucidate the full catalytic cycle, which comprises …
