The monolayer AlN is one of graphene-like 2D material. On the basis of density functional theory (DFT) calculations, the adsorption of CO2, CO, H2, N2, CH4, O2 and NO on the monolayer AlN was investigated. Due to the dipole moment of the Al-N bond, the gas molecules can be adsorbed directly on the AlN sheet. This avoids the problem about formation of metal clusters using metal decorated carbon nanostructures...
To investigate the value of ultrasound for the assessment of endometrial receptivity during in vitro fertilization (IVF) and embryo transfer (ET).Only those patients in their first IVF cycle, followed a standard long gonadotropin releasing hormone (GnRH) agonist long ovarian stimulation regimen, and had 2 highest scoring embryos transferred on day 3 were included in the study. A 3D ultrasound examination...
Surface-enhanced Raman scattering (SERS) can provide vibrational information with molecular specificity and potential single-molecule sensitivity. SERS studies on pure transition metals, however, remain challenging due to the weak SERS activity of transition metals compared to coinage metals. Here we fabricated alumina-supported Pd island films by depositing laser-ablated Pd colloids onto an Al substrate...
