Abstract One pot synthesis of 2,5‐dimethylfuran (2,5‐DMF) from saccharides under mild conditions is importance for the production biofuel and fine chemicals. However, requires a multitude active sites suffers slow kinetics due to poor diffusion in most composite catalysts. Herein, metal‐acid functionalized 2D metal‐organic framework (MOF; Pd/NUS‐SO 3 H), as an ultrathin nanosheet 3–4 nm with Lewis acid, Brønsted metal sites, was prepared based on diazo method acid modification subsequent...
Bird strikes on aero-engines are a significant factor contributing to aircraft accidents. Airworthiness regulations in various countries impose specific requirements engine resistance bird strikes. Currently, the International Civil Aviation Organization (ICAO), Federal Administration (FAA) of United States, and China (CAAC) categorize severity levels species that pose threats flight safety based their weight within relevant regions. Consequently, this thesis introduces probabilistic risk...
Abstract A palladium‐catalyzed [5+1] annulation of 2‐(1‐arylvinyl) anilines and α‐diazocarbonyl compounds has been developed, affording a series multi‐functionalized quinolines in moderate to good yields. This procedure proceeded with the sequential insertion N−H bond palladium carbene, intramolecular Heck reaction decarboxylation steps. In this reaction, alkyl 2‐diazophenylacetates served as C1 building block, which represents key compliment diazo chemistry. magnified image
Currently, low intimacy between hydrogenation sites and acidic causes unsatisfactory catalytic activity selectivity for the synthesis of 2,5-hexanedione from C6 furan aldehydes (5-methylfurfural, 5-hydroxymethylfurfural). Herein, iodine(I) modification Pd-supported catalysts (such as PdI/Al2 O3 PdI/SiO2 ) was investigated to modulate sites. Unlike Pd that produced 71.4 % yield 2-hydroxymethyl-5-methyl tetrahydrofuran via an overhydrogenation route 5-methylfurfural, PdI showed a high...

The gradual acceleration of the aging population in China has led to an increased demand for mobility aids, and reliability domestic wheeled walking-aid is one their important attributes, but there little research on aids. This paper conducts failure mode, effects criticality analysis walking-aid. By collecting, collating analyzing 26 modes, key modules are chassis lifting system. obtained, data analyzed find out that lifetime distribution model log-normal 0.95 lower confidence limit life product
Negative-pressure artificial muscles based on internal support and flexible skin provide a way to develop high-performance muscles. However, the random disordered wrinkles formed during contraction may lead uncertainty in actuation behavior, but inextensible weakens elasticity passive deformability of these In this work, new type negative-pressure muscle is developed by combining circumferentially pre-stretched soft axial fiber constraints. The design concept has been demonstrated comparison...
