Self-aligned patterning of tantalum oxide on Cu/SiO through redox-coupled inherently selective atomic layer deposition.

Atomic-scale precision alignment is a bottleneck in the fabrication of next-generation nanoelectronics. In this study, a redox-coupled inherently selective atomic layer deposition (ALD) is introduced to tackle this challenge. The 'reduction-adsorption-oxidation' ALD cycles are designed by adding an in-situ reduction step, effectively inhibiting nucleation on copper.

Promotional Effect of H Pretreatment on the CO PROX Performance of Pt/CoO: A First-Principles-Based Microkinetic Analysis.

Atomic Pt studded on cobalt oxide is a promising catalyst for CO preferential oxidation (PROX) dependent on its surface treatment. In this work, the CO PROX reaction mechanism on CoO supported single Pt atom is investigated by a comprehensive first-principles based microkinetic analysis. It is found that as synthesized Pt/CoO interface is poisoned by CO in a wide low temperature window, leading to its low reactivity.

Inherently Area-Selective Atomic Layer Deposition of Manganese Oxide through Electronegativity-Induced Adsorption.

Manganese oxide (MnO) shows great potential in the areas of nano-electronics, magnetic devices and so on. Since the characteristics of precise thickness control at the atomic level and self-align lateral patterning, area-selective deposition (ASD) of the MnO films can be used in some key steps of nanomanufacturing. In this work, MnO films are deposited on Pt, Cu and SiO substrates using Mn(EtCp) and HO over a temperature range of 80-215 °C.

Noninvasive genotyping of 9 Y-chromosome specific STR loci using circulatory fetal DNA in maternal plasma by multiplex PCR.

Background: Human Y-Chromosome specific STR (Y-STR) has now become a useful loci in casework. However, noninvasive genotyping of multiple Y-STR loci and its application in prenatal genetic diagnosis haven't been reported. The purpose of this study is to develop a Y-STR multiplex PCR amplification system that is suitable for the amplification of short-sized templates of circulatory male fetal DNA and use the established multiplex in noninvasive prenatal genetic diagnosis and its further applications in forensic casework.
