The direct coupling of aldehydes with petrochemical feedstock alkenes and alkynes would represent a practical streamlined approach for allylation allenylation chemistry. However, conventional approaches commonly require preactivated substrates or strong bases to generate allylic propargylic carbanions only afford branched propargylation products. Developing mild selective access synthetically useful linear products is highly desirable, albeit formidable challenges. We report strategy using...

In the field of condition monitoring, main measures for classification recognition are one‐dimensional (1D) signal analyses from time, frequency, or time—frequency domains. However, raw signals, unclear dominance features, weakness and sparsity characteristic frequencies, noise interference increase difficulty feature extraction 1D data. Therefore, to address these issues fully utilize phase information status a bispectral technology deep learning‐network‐based method image proposed in this...

Photocatalysis based on chromophores such as porphyrin, coumarin, anthraquinone, and pyrene is a promising technology to achieve green synthesis of various high-value chemicals, but the robust non-covalent immobilization onto light-inert scaffolds for industrialization-oriented heterogeneous photocatalysis remains challenging. In this work, simple universal strategy presented preparing highly efficient recyclable photocatalysts from chromophores, which achieved via biotinylation chromophore...

We proposed and experimentally demonstrated paralleled Mach-Zehnder interferometers (MZIs) in few-mode multicore fiber (FM-MCF) for temperature strain discriminative sensing. A section of FM-MCF is sandwich-spliced between two single-mode (SM-MCF) with a rotational offset. The arbitrarily controlled angular misalignment generates intentional intermodal interferences outer cores the thus multiple MZI structures are implemented. Experimental results show that sensitivities 105.8 pm/°C 223.6...

An eight-member series of CF3-substituted difluorophosphorus corroles was prepared for establishing a structure–activity profile these high-potential photosensitizers. It consisted preparing all four possible isomers the monosubstituted corrole and complexes with 2-, 3-, 4-, 5-CF3 groups on macrocycle's periphery. The synthetic pathway to derivatives, beginning (tpfc)PF2, involves two different initial routes: (i) direct electrophilic CF3 incorporation using FSO2CF2CO2Me copper iodide, or...

Abstract There have been few reports on the substituent effect of main‐group‐element corrole complexes as ligand‐centered homogeneous electrocatalysts for hydrogen evolution reaction (HER). The key to comprehend catalytic mechanism and develop efficient catalysts is elucidation effects electronic structure performance energy‐related small molecules. In this work, “push‐pull” substituents electrocatalytic HER phosphorus corroles was investigated by using 5,10,15‐tris(phenyl) (1P),...

Abstract The economical consideration of using an electrocatalyst in energy‐related field, composed non‐precious/sustainable elements is quite noteworthy. In this work, the phosphorus(V) complex tris‐(pentafluorophenyl)corrole [(TPFC)P V (OH) 2 ] was reported as for hydrogen evolution reaction (HER). electrochemical studies revealed that HER experienced a ECEC pathway (E: electron transfer step, C: chemical step), and possible intermediate [P ]−H species suggested. (TPFC)P displayed...

Abstract Owing to the merits of automatic feature extraction and depth structure, intelligent fault diagnosis based on deep neural networks has become a great concern. However, non-fault state monitoring data volume actual industrial machinery is rich, whereas insufficient weak. Furthermore, achieving multiple mixed-fault diagnoses using skewed distributions extremely difficult. A reconstruction sparse auto-encoder (AE) model-based method for mixed faults proposed in this study bridge these...

A set of gold corrole complexes containing four different β-substituent groups (Br/I/CF3), namely, 4Br–Au, 4I–Au, and 4CF3–Au, were investigated; all showed room temperature phosphorescence. The phosphorescence quantum yields the corroles determined using tetraphenylporphyrin as a reference: Φph (4I–Au, 0.75%) > (4Br–Au, 0.64%) (4CF3-Au, 0.38%). 4CF3–Au exhibited near-IR emission (858 nm, aerobic); absorbance intensity for Q-band was higher than that Soret band. Complex 4I–Au longer lifetime...
