Cu-Co bimetallic oxide quantum dot decorated nitrogen-doped carbon nanotubes: A high-efficiency bifunctional oxygen electrode for Zn-air batteries. Adv. Funct. Mater. 2017, 27, 1701833. [CrossRef]H. Cheng, M.L. Li, C.Y. Su, N. Li, Z.Q. Liu, CuCo bimetallic oxide...
The SiiE protein has been shown to interact with more than 100 calcium ions and to mediate adhesion to polarized epithelial cells23. Based on the crystal structure of one of the BIg domains, it is suggested that the calcium ions provide a cross-link between the LPS molecule of the ...
1a). Briefly, triethynylbenzene was used as the monomer, while copper foil was applied as catalyst and supporter. Large-area HsGDY film was obtained on the surface of copper foil through a cross-coupling reaction. HsGDY film was peeled off from copper foil with hydrochloric acid and rinsed ...
To understand the response of SiC and SiCN thin films to the scratch loading the residual scratch grooves were cross-sectioned using the Focused Ion Beam milling with the FEI Quanta 3D Dual-Beam SEM/FIB system utiliz- ing Ga+ ion source. Various perpendicular and longitudinal cross sections ...
QTL mapping has been the main experimental approximation to fill the gap between genotype and phenotype in yeast [66]. In this approach, a population of individuals derived from a cross is genotyped and phenotyped, allowing the statistical correlation between genotype and phenotype to map genes aff...
Reactive nitrogen (N) plays a pivotal role in supplying N to plants and soil microbes, but it has negative environmental impacts through influencing the quality of water and air, which in turn influences human health. Thus, there is an urgent necessity to maximize N benefits while reducing the...
Phase separations occurred during electrospinning, creating the discontinuous and long rodlike PMMA phase and the continuous PAN phase. After carbonization, many hollow cores are created within the resultant carbon fibers. Fig. 9.19D–F shows SEM images of the cross sections of the as-prepared C...
Electroluminescence efficiency is crucial for the application of quantum-dot light-emitting diodes (QD-LEDs) in practical devices. We demonstrate that nitrogen-doped carbon nanodot (N-CD) interlayer improves electrical and luminescent properties of QD-LEDs. The N-CDs were prepared by solution-based ...
The size of these dots is in the range of 2–3 Å, indicating that each bright dot corresponds to one individual Co atom. The enlarged view of the selected region (Fig. 3c) reveals that each Co atom is centred by the light elements (C, N and/or O). Additional STEM images are...
