Metal oxides have advantages over the traditional noble metals to be used as substrate materials for surface‐enhanced Raman spectroscopy (SERS) with low cost, versatility, and biocompatibility, but their enhancement factors are generally quite low with a poor limit of detection. Here, ultrathin molybdenum dioxide (MoO2) nanosheets synthesized by chemical vapor deposition demonstrated in large area...
Transcription factor activator protein-2β (TFAP-2β) was previously reported to constituted promoter activity in endometrial carcinoma (EC). We evaluated the role of TFAP2B in ECs using publicly available data from The Cancer Genome Atlas (TCGA).The relationship between clinical pathologic features and TFAP2B were analyzed with the Wilcoxon signed-rank test and logistic regression. Clinicopathologic...
Background LncRNA Gas5 is known to be a key control element during growth, differentiation and development in mammalian species. However, the role and function of Gas5 in growth plate chondrocytes has not been determined. Methods The overexpression and knockdown models of Gas5 and miR-21 in cells and animals were constructed. Cell survival was determined by MTT assay and flow cytometry. Animal biochemical...
Strain engineering shows promising applications in low‐dimensional materials. It is demonstrated that the bandgap of few‐layered black phosphorus can be effectively reduced by out‐of‐plane compressive strain, resulting in a significant modulation of the vertical electrical performance of black phosphorus and even inducing a nonlinear current–voltage curve to linear current–voltage curve transition...
When material dimensions are reduced to the nanoscale, exceptional physical mechanics properties can be obtained that differ significantly from the corresponding bulk materials. Here we review the physical mechanics of the friction of low-dimensional nanomaterials, including zero-dimensional nanoparticles, one-dimensional multiwalled nanotubes and nanowires, and two-dimensional nanomaterials—such...
