Single-phased, high-color-rendering index (CRI) white-light phosphors are emerging as potential phosphor-converted white-light-emitting diodes (WLEDs) and as an alternative to blends of tricolor phosphors. However, it is a challenge to create a high CRI white light from a single-doped activator. Here, we present a hig…
Dynamic control of conductivity and optical properties via atomic structure changes is of technological importance in information storage. Energy consumption considerations provide a driving force towards employing thin materials in devices. Monolayer transition metal dichalcogenides are nearly atomically thin materia…
The surface-assisted polymerization and cyclodehydrogenation of specifically designed organic precursors provides a route toward atomically precise graphene nanoribbons, which promises to combine the outstanding electronic properties of graphene with a bandgap that is sufficiently large for room-temperature digital-lo…
Graphene hosts a unique electron system in which electron-phonon scattering is extremely weak but electron-electron collisions are sufficiently frequent to provide local equilibrium above the temperature of liquid nitrogen. Under these conditions, electrons can behave as a viscous liquid and exhibit hydrodynamic pheno…
Integration of electrochemical capacitors with silicon-based electronics is a major challenge, limiting energy storage on a chip. We describe a wafer-scale process for manufacturing strongly adhering carbide-derived carbon films and interdigitated micro-supercapacitors with embedded titanium carbide current collectors…
Heterostructures comprising different monolayer semiconductors provide an attractive setting for fundamental science and device technologies, such as in the emerging field of valleytronics. We realized valley-specific interlayer excitons in monolayer WSe2-MoSe2 vertical heterostructures. We created interlayer exciton…
Η περιβαλλοντική μόλυνση είναι ένα από τα πιο σοβαρά προβλήματα που αντιμετωπίζει ο πλανήτης μας τα τελευταία χρόνια. Η έντονη ανθρώπινη δραστηριότητα έχει οξύνει αυτό το φαινόμενο. Τις τελευταίες δεκαετίες η εντατική χρήση φυτοφαρμάκων είχε ως αποτέλεσμα τη ρύπανση του υπόγειου νερού µε οργανικές ενώσεις. Οι οργανοχλ…
Les superalliages à base nickel des turbines aéronautiques sont susceptibles de subir des phénomènes de corrosion et/ou d’oxydation à haute température par les environnements agressifs rencontrés en service. Aussi, des revêtements d’aluminure sont appliqués par dépôt chimique afin d’assurer la protection des pièces co…
O desenvolvimento dos aços inoxidáveis Super-Martensíticos (SM) nasce da necessidade de implementar novas tecnologias, mais econômicas e amigáveis ao meio ambiente. Os aços inoxidáveis SM são uma derivação dos aços inoxidáveis martensíticos convencionais, diferenciando-se basicamente no menor teor de carbono, na adiçã…
Currently, there is the need for broader implementation in production of powder alloy steels. In the literature there are publications on the properties of these materials, methods of alloying. However, their fragmentation makes it difficult to use these data to develop new powder alloy steels, and their introduction…
The technology of modifying aluminum and nickel alloys nanodispersnymi compositions. Built comparative histogram of the mechanical properties of deformed aluminum alloys before and after modification. Reasonable choice of type and method of nanomodifier tableting. Nanodispersed modifiers were prepared by plasma chemic…
In the metallurgical production such as roasting of pellets and caking of agglomerate on conveyor type machines refer to thermal cyclic recurrence processes. At the same time the working bodies of conveyor machines are experiencing not only the impact of high cyclically varying temperatures, but and abrasion wear part…
Questions which are related to the process of redistribution of hydrogen between the phases during crystallization of aluminium and its alloys are examined in the article.A research result is: development of theoretical bases of process of redistribution of hydrogen between the phases during crystallization of alumini…

Les ultrasons focalisés permettent d’effectuer des traitements thérapeutiques ciblés dans le corps humain. Dans le domaine des applications cardiovasculaires, ils permettent de détruire des caillots sanguins susceptibles de se former dans le système vasculaire. Dans ce cas, les mécanismes de thrombolyse sont largement…
