Abstract Ionic liquids as anticorrosion agents have a wide spectrum of unique properties, which make them less harmful than the majority of typical organic corrosion inhibitors in antifreeze. The synthesis of ionic liquids enables them to be provided with the desired physicochemical and thermodynamical properties by the appropriate selection of cations, anions, and alkyl substituents on the cations. The aim of this paper is the synthesis of the gemini ionic salt (ionic liquid) made up of two imidazole rings with a linear alkyl substituent with 10 carbon atoms, bonded by a 1,4-dimethylphenyl moiety. Such compounds are studied in view of steel protection against oxidizing and corrosive effects. The compound was obtained in a satisfactory yield.

Abstract Epitaxial growth is of significant importance over the past decades, given it has been the key process of modern technology for delivering high-quality thin films. For conventional heteroepitaxy, the selection of proper single crystal substrates not only facilitates the integration of different materials but also fulfills interface and strain engineering upon a wide spectrum of functionalities. Nevertheless, the lattice structures, regularity and crystalline orientation are determined once a specific substrate is chosen. In this work, we reveal the growth of twisted oxide lateral homostructures with multiple conjunction degree of freedom. The twisted lateral homostructures with atomically sharp interfaces can be composed of epitaxial “blocks” with different crystalline orientations, ferroic orders and phases. We further demonstrate that this approach is universal for fabricating various complex systems. Our results establish an efficient pathway towards twisted lateral homostructures, allowing epitaxial films to be arbitrarily tailored at designated positions with unbounded in-plane conjunction tunability.

Separate Class

Deep eutectic solvents (DESs) are a class of mixtures with melting points notably lower than those of their raw constituent components. These liquids have found a tremendously wide spectrum of applications in the last two decades of their research, so their contact and interaction with technical metals and alloys are inevitable. Therefore, the corrosivity of DESs towards metals is an extremely important topic. This review summarizes research efforts collected in the last two decades related to the corrosion rate of various metals in different DESs. Since the DESs are mainly composed of organic raw compounds, and by their physicochemical properties they may be regarded as a separate class of ionic liquids, the literature data about DESs corrosivity has been compared to the data related to the corrosivity of various organic solvents and ionic liquids as well. All the results gained until now show significantly low corrosivity of DESs. This observation is discussed in relation to the chemical composition of DESs. The absence of the oxidizing agents, the inhibitory action of organic ions and molecules, high viscosity and low electrical conductivity have been recognized as the main factors contributing to the low metal corrosion rate in DESs.

<p>Polycystic ovary syndrome (PCOS) is the most frequent endocrine disorder existing in women in their reproductive years and it is one of the most evaluated and discussed subjects of reproductive medicine with regard to its diagnosis and treatment.<br />Patients with PCOS constitute the most difficult population in the management of infertility. The factors that increase the success rates in the treatment of PCOS infertility are: pretreatment changes in life style, dietetic and psychological support, a detailed evaluation of the couple and the appropriate selection of the treatment protocol, a wide-spectrum approach to maintaining ovarian and endometrial synchronization in the management of the cycle, and well-developed laboratory conditions to support embryonic quality. However, even if these conditions are provided, OHSS, cancellations of the cycle, poor oocyte, and embryo qualities, unsuccessful fertilization and implantation, chromosomal abnormalities and early losses may still be experienced.</p>
