Broad Overview

This volume gathers the lectures notes of Session CVII of the Les Houches summer school of Physics, entitled “Current trends in Atomic Physics”. The school took place in July 2016 and had the goal to give the participants a broad overview of Atomic Physics as a whole, and in particular its connections to other areas of physics, such as condensed-matter and high-energy physics. The book comprises twelve chapters corresponding to lectures delivered at the school.

AbstractPulsed Laser Deposition (PLD) allows the ablation of nonconductive and high melting point target materials and the preparation of films with complex composition. High energy impact leads to melting and evaporation of the target material in a single step. In case of mullite ablation, the flux of the metal components is stoichiometric. Under reduced pressure the oxygen content in the layers decreases. However, after a short oxidation treatment, the formation of mullite in the coating is completed, as confirmed by IR spectroscopy and XRD investigations. For a commercial Si-SiC precoated C/C material, the effectiveness of additional PLD mullite layers as outer oxidation protection is tested in the temperature range 773 K < T < 1873 K. Mullite coatings with a thickness of 2.5 pm improve the oxidation behaviour significantly. Because of SiO2 formation at the mullite-SiC interface, all samples exhibited a mass increase upon oxidation. For oxidation durations of three days, only amorphous SiO2 is formed at the mullite-SiC interface. The inward diffusion of oxygen across the outer mullite-containing layer controls the kinetics of the reaction, as was deduced from 18O diffusivity measurements in PLD mullite layers. At temperatures close to the eutectic temperature (1860 K), mullite can seal defects. The calculated oxidation rates resulting from the diffusion parameters in SiO2 and mullite are close to the thermogravimetric data.

The droplet-based microfluidic technology has a potent high throughput platform for biomedical research and applications [1]. Recently, Link et al. showed that an electric field can be very useful to control water droplet in carrier oil [2]. In this research, simultaneous droplet formation and sorting has been demonstrated using an electric field, allowing very precise droplet sorting to different outlets depending on the electrical actuation.

Проведено исследование фазовых равновесий в тройной системе Sn–As–P в области высокой концентрации летучих компонентов. Методами рентгенофазового и дифференциального термического анализа изучены сплавы политермического разреза SnAs–P. Показано, что растворимость фосфора в моноарсениде олова в направлении этого разреза менее 0.05 мол.д. фосфора. Построена Т-х диаграмма политермического сечения SnAs–Р. Наличие на Т-х диаграмме горизонтали при температуре 827±2 К соответствует реализации в системе Sn–As–P нонвариантного перитектического равновесия L + (d) ↔ b + g , где (d), b и g – трехкомпонентные твердые растворы на основе As1-xPx, SnAs и SnP3 соответственно     REFERENCES Zhang W., Mao J., Li S., Chen Z., Guo Z.
