“…In particular, the relative short distance between two copper atoms in diatomic copper makes an easier electron transfer process, which could produce an excited state of electrons, and then lead to a stronger ultraviolet absorption capacity of the diatomic copper catalyst. 40,41 We further examined the photoluminescence spectra of PCN and DAS-Cu@PCN to investigate their optical characteristic change when exposed to visible light. The PL intensity dramatically dropped with the addition of dual Cu sites (Fig.…”

This paper studied favorable low-temperature plasma (LTP) surface treatment modes for Carbon Fiber Reinforced Polymer (CFRP)/Al7075 single-lap joints using complex experimental methods and analyzed the failure modes of the joints. The surface physicochemical properties of CFRP after LTP surface treatment were characterized using scanning electron microscopy (SEM), contact angle tests, and X-ray photoelectron spectroscopy (XPS). The influence mechanism of LTP surface treatment on the bonding properties of CFRP/Al7075 single-lap Joint was studied. The results of the complex experiment and range analysis showed that the favorable LTP surface treatment parameters were a speed of 10 mm/s, a distance of 10 mm, and three repeat scans. At these parameters, the shear strength of the joints reached 30.76 MPa, a 102.8% improvement compared to the untreated group. The failure mode of the joints shifted from interface failure to substrate failure. After low-temperature plasma surface treatment with favorable parameters, the CFRP surface exhibited gully like textures, which enhanced the mechanical interlocking between the CFRP surface and the adhesive. Additionally, the surface free energy of CFRP significantly increased, reaching a maximum of 78.77 mJ/m2. XPS results demonstrated that the low-temperature plasma surface treatment led to a significant increase in the content of oxygen-containing functional groups, such as C-O, C=O, and O-C=O, on the CFRP surface.

Lead is an environmental pollutant that has been present for a long time and has harmful effects on human health. The essential task of protecting public health requires sensitivity and selectivity in monitoring and removing Pb2+ from the environment. NH2‐Al‐MOF was utilized to create a chemical sensor that can quickly detect Pb2+ ions. By combining the Al–metal–organic framework (MOF) with 2‐Acetyl‐4‐methylpyridine, the 2A4MP=N‐Al‐MOF sensor was developed. The NH2‐Al‐MOF and 2A4MP=N‐Al‐MOF sensor were characterized by X‐ray photoelectron spectroscopy (XPS), Brunner–Emmet–Teller (BET), X‐ray diffractometer (XRD), Fourier transform infrared (FT‐IR), and scanning electron microscopy (SEM). Characterization results indicate that 2‐Acetyl‐4‐methylpyridine was effectively incorporated into the Al‐based MOF, and the 2A4MP=N‐Al‐MOF sensor's pore structure is primarily made up of mesopores. To determine the optimal conditions for detecting Pb2+ ions using the 2A4MP=N‐Al‐MOF sensor via fluorescence measurement, several experimental studies have been carried out. A steady spectroscopic signal can be achieved with a sensor that has a response time of below 30 seconds. According to ICH guidelines, the suggested methods underwent validation for LOD, LOQ, linearity, and precision. The results show that the 2A4MP=N‐Al‐MOF chemosensor has a high sensitivity and selectivity toward the Pb2+ analyte, with a detection limit of 0.171 ppm and a linear range of 0.0–2.0 ppm. The 2A4MP=N‐Al‐MOF chemosensor also exhibited good reproducibility, with a relative standard deviation of less than 3%. As a result, the Pb2+ ions were sensitively and selectively identified in various environmental water samples using the 2A4MP=N‐Al‐MOF sensor.
