The kinetics of elemental inter-diffusion in Ag–Cu nanoalloys of 32–34 atoms around 80:20 composition is theoretically investigated by combining analytic-potential and first-principles calculations. An extremely varied behavior is found, with transformation times ranging from tens of nanoseconds to weeks at room tempe…

본 논문에서는 무한 도체 평판의 슬릿 부근에 도체판을 부가하여 슬릿으로 침투하는 전자파의 저감 특성을 검토하였다. 이론 해석에는 FDTD 법을 사용하였으며, 부가 도체판의 형상 및 길이, 간격, 두께의 변화에 따른 침투 전계의 특성을 계산하여 부가 도체판의 구조 변화가 침투 전자파의 저감 특성 및 차폐 효과 특성에 미치는 영향을 고찰하였다. 그 결과, 부가 도체판의 구조 변화에 따라 차폐 효과, 침투 전계의 특성이 변화하는 것을 관찰할 수 있었고, 침투 전계를 최소로 하는 부가 도체판의 최적 구조가 있음을 확인할 수 있었다. This paper presents th…

Perhaps the best way to illustrate the techniques of the previous chapters is to review a classical lesson learned from a real case encountered in the industry. This will aid in the understanding of the principles set forth and help the reader to assess if he or she has grasped the concepts. This example involves an a…
We present some properties of the groups with the infinite non-quasicentral periodic nodal subgroup. Our main results are formulated in Theorem 1, 2 and Theorem 3, 4. 2000 Mathematics Subject Classification: 20F22, 20F25
采用微弧氧化/溶胶-凝胶工艺,在AZ91D镁合金表面制备羟基磷灰石涂层,并研究了镁基羟基磷灰石涂层的形貌、结构、组成及其电化学性能。结果表明,微弧氧化电流密度为0.5A/cm2时,采用溶胶-凝胶法制备的涂层表面均匀、多孔且紧密;Ca/P摩尔比（1.70）高于溶胶配制的比例（1.67）,是由于CO2-3替代了磷灰石晶格中的PO3-4所致。电化学测试结果表明,微弧氧化电流密度为0.5A/cm2时,羟基磷灰石涂层在Hank’s溶液中具有较低的腐蚀电流密度、较高的总阻抗和腐蚀电阻;浸泡实验表明该涂层有利于诱导磷灰石涂层的形成。

Na formação de interfaces e superfícies, há uma gama imensa de parâmetros que têm influência em seu desenvolvimento e é praticamente impossível que se possa distinguir experimentalmente cada um desses parâmetros. Buscamos, de forma teórica, considerar apenas alguns parâmetros e comparar nossos resultados teóricos com…
The feature sizes of only a few nanometers in modern nanotechnology and next-generation microelectronics continually increase the demand for suitable nanometrology tools. Grazing incidence small-angle X-ray scattering (GISAXS) is a versatile technique to measure lateral and vertical sizes in the nm-range, but the trac…
Pb$_{0.77}$Sn$_{0.23}$Se is a novel alloy of two promising thermoelectric materials PbSe and SnSe that exhibits a temperature dependent band inversion below 300 K. Recent work has shown that this band inversion also coincides with a trivial to nontrivial topological phase transition. To understand how the properties c…
Molecules adsorbed on some metal surfaces such as silver, copper and gold, can exhibit enormous Surface-enhanced Raman Scattering (SERS). The SERS effect has historically been associated with substrate roughness on two characteristic length scales [1,2]. Surface roughness on the 10 to 100 nm length scale supports the…
The number of different types of Surface-enhanced Raman Scattering (SERS) substrates available for experimentation is increasing at high speed. New alternatives are introduced and explored every year in the literature including both novel nano-particles in solution as well as self-assembled or engineered structures wi…
Diamond has been under spotlight in industry since the discovery of its extraordinary mechanical properties, high wear resistance and excellent chemical inertia. These properties enable diamond a competitive candidate for industrial and biomedical applications. In the present research, the tribological properties of t…

Die Muscle-RING-finger (MuRF) Proteine sind E3-Ubiquitin-Ligasen, die im Muskelgewebe den Ubiquitin-Proteasom-System abhängigen Abbau von Proteinen vermitteln. MuRF1 wird in der Muskelatrophie verstärkt synthetisiert, was zu einem gesteigerten Proteinabbau und damit zum Verlust von Muskelmasse führt. Zudem sind Mäuse,…
Secondary ion mass spectrometry (SIMS) with a massive cluster projectile and run in the event-by-event bombardment/detection mode has been applied to perform nanoscale analysis. Massive clusters, specifically Au_(400)^(4+), at hypervelocity feature efficient production of multiple secondary ions (SIs) desorbed from a…
