Progress of research on the bonding-strength improvement of two-layer adhesive-free flexible copper-clad laminates.

The arrival of the 5G era has placed high demands on the electronic products. Developing thin, light, and portable electronic products capable of simultaneously improving the transmission rate and reducing the signal delay and transmission loss is necessary to meet such demands. The traditional three-layer, adhesive, flexible copper-clad laminate (3L-FCCL) cannot satisfy these demands because of its adhesive component.

Exploring the potential of a polyvinyl alcohol/chitosan-based nanofibrous matrix for erythromycin delivery: fabrication, and evaluation.

This study aimed to investigate the potential of polyvinyl alcohol/chitosan nanofibers as a drug delivery system for erythromycin. Polyvinyl alcohol/chitosan nanofibers were fabricated using the electrospinning method and characterized using SEM, XRD, AFM, DSC, FTIR, swelling assessment and viscosity analysis. The drug release kinetics, biocompatibility, and cellular attachments of the nanofibers have been evaluated using release studies and cell culture assays.

Formation mechanism of disc-shaped calcite-a case study on sp. MF-2.

Research on the biogenic-specific morphology of carbonate minerals has made progress in the fields of biomineralization and industrial engineering. In this study, mineralization experiments were performed using sp. MF-2, including its biofilms.

Size-controlled synthesis of porous ZnSnO nanocubes for improving formaldehyde gas sensitivity.

During the detection of formaldehyde, sensitivity and selectivity is still a challenging issue for most reported gas sensors. Herein, an alternative formaldehyde chemosensor that is based on porous ZnSnO nanocubes was synthesized. The products are characterized by XRD, SEM, TEM (HRTEM), XPS, PL measurements and N adsorption-desorption.

MXene-regulation polyamide membrane featuring with bubble-like nodule for efficient dye/salt separation and antifouling performance.

Removing salt from dye/salt mixtures using nanofiltration (NF) membranes needs to be improved to ensure high permeability, high selectivity, and antifouling performance. In this study, we used an interfacial polymerization (IP) technique to create a novel thin-film nanocomposite NF membrane by introducing two-dimensional MXene TiCT into the polyamide (PA) layer. Enhanced IP reaction rate facilitated the overflow of residual solvent from the fresh PA layer's edge due to the MXene-mediated IP strategy, resulting considerable bubble-like nodules on the membrane surface.

Different effects of soil bacterial communities affected by biocontrol agent YH-07 on tomato wilt inhibition.

Bio-organic fertilizers based on biocontrol microorganisms have been widely applied to suppress soilborne diseases and improve crop yields. Studies on beneficial biocontrol agents have promoted the development of the bio-organic fertilizers in China. Our previous study demonstrated that a biocontrol agent, sp.

Chemodivergent synthesis of -(pyridin-2-yl)amides and 3-bromoimidazo[1,2-]pyridines from α-bromoketones and 2-aminopyridines.

-(Pyridin-2-yl)amides and 3-bromoimidazo[1,2-]pyridines were synthesized respectively from α-bromoketones and 2-aminopyridine under different reaction conditions. -(Pyridin-2-yl)amides were formed in toluene C-C bond cleavage promoted by I and TBHP and the reaction conditions were mild and metal-free. Whereas 3-bromoimidazopyridines were obtained in ethyl acetate one-pot tandem cyclization/bromination when only TBHP was added, the cyclization to form imidazopyridines was promoted by the further bromination, no base was needed, and the versatile 3-bromoimidazopyridines could be further transferred to other skeletons.
