It has long been under debate whether the electron transport performance of graphene could be enhanced by possible occurrence van Hove singularities in grain boundaries. Here, we provide direct experimental evidence to confirm existence singularity states close Fermi energy certain ordered boundaries using scanning tunneling microscopy. The intrinsic atomic and electronic structures two boundaries, one with alternative pentagon heptagon rings other pair octagon rings, are determined. is...

The doping types of graphene sheets are generally tuned by different dopants with either three or five valence electrons. As a five-valence-electrons element, however, nitrogen in have several substitutional geometries. So far, their distinct effects on electronic properties predicted theoretical calculations not been well identified. Here, we demonstrate that the can be N monoelement under proper growth conditions using chemical vapor deposition (CVD), characterized combining scanning...

Abstract Objectives To investigate the antidepressant effects of Xiaoyaosan (XYS) in a chronic unpredictable mild stress (CUMS) depression model. Methods The changes behaviour and plasma metabolic profiles were investigated after four-week CUMS exposure treatment. Drugs administered during period CUMS, with healthy group serving as negative controls, fluoxetine venlafaxine groups positive controls. Plasma samples collected at 28th day, profiling was measured using NMR, followed by...

Corn stalk lodging is caused by different factors, including severe wind storms, cannibalization, and rots, it leads to yield loss. Determining how rapidly evaluate corn resistance will assist scientists in the field of crop breeding understand contributing factors managing moisture, chemical fertilizer, weather conditions for growing. This study proposes a non-destructive direction-insensitive method, using strain sensor two single axis angle sensors measure field. An equivalent force whose...

The aim of this work is to identify the adulteration edible gelatin using near-infrared (NIR) spectroscopy combined with supervised pattern recognition methods. spectral data obtained from a total 144 samples consisting six kinds adulterated gels different mixture ratios were processed multiplicative scatter correction (MSC), Savitzky–Golay (SG) smoothing, and min-max normalization. Principal component analysis (PCA) was first carried out for analysis, while categories could not be clearly...

The retention of CdS/ZnS QDs on the epidermis has been confirmed to be one core procedures during root uptake process. However, mechanisms woody plant were poorly understood for lacking an appropriate QD quantitative method. In this study, a novel method in situ determination retained was established using synchronous nanosecond time-resolved fluorescence spectroscopy. No correlations between Kf values oleylamine-CdS/ZnS epidermal tissues and surface/bulk composition mangrove observed (p >...
