Hexagonal boron nitride (h-BN) is a layered material analogous to graphite that exhibits a hexagonal crystal structure with the lattice parameters of a = 2.50 Å, c = 6.66 Å. In such an h-BN crystal, the hexagonal layers stack each other, and the B3N3 hexagons overlap and alternate with N3B3 hexagons (Figure 4.1). h-BN…
Two-dimensional (2D) nanosheets, because of their ultrasmall thickness in atomic or molecular range and innite lateral dimensions, have been widely considered as the thinnest functional materials [1]. e original work of this 2D materials can be dated back to the 1950s, when some clay minerals dispersed well in water,…
This specification covers the requirements for silver deposited on metal parts with a copper strike between the basis metal and the silver deposit.
У статті розглянуто комплексний підхід до розроблення засобів експрес-діагностики технічного стану лінійної частини магістральних трубопроводів, який включає застосування експериментальних і розрахункових методів визначення напружено-деформованого стану трубопроводів на небезпечних ділянках, у тому числі за наявності…

Living machines are not intelligently designed and will often be redundant and overly complex – Sir Paul Nurse A reconstructed network can have many functional states even in the same environment. Constraint-based optimization problems can have multiple equivalent solutions that yield the same numerical value of the o…
This specification covers the engineering requirements for electrodeposition of cadmium-titanium on metal parts and the properties of the deposit.
X (where Me = Cu, Ag and X = S, Se, Te) display a wide variety of physical and physical and chemical properties, that makes them promising for electronic equipment [1, 2]. A wide range of electrical and thermal properties, the ability to control these properties via controlled deviation from stoichiometry and high par…
Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.

We have experimentally investigated the control of Marangoni flow around a micro bubble using photothermal conversion. Using a focused laser spot acting as a highly localized heat source on Au nanoparticles/dielectric/Ag mirror thin film enables us to create a micro bubble and to control the temperature gradient aroun…
Similarities between carbon and boron nitride (BN) are striking. Indeed, BN is isoelectronic to carbon. It exhibits dierent polymorphs, including a wurtzite structure (w-BN), a sphalerite (cubic) structure (c-BN), and a hexagonal structure (h-BN). e two latter forms are strongly related to the two common carbon allotr…

Les matériaux tellurites possèdent des propriétés optiques non linéaires exceptionnelles, avec des valeurs de la susceptibilité optique non linéaire d’ordre trois de l’ordre de 10 à 50 fois supérieures à celle de la silice pure, favorisant alors l’efficacité des effets non linéaires. L’origine de ces propriétés optiqu…
Long BNNTs were synthesized using an optimized ball milling and annealing process. In a typical process, amorphous boron (B) powder was rst loaded into a stainless steel milling jar with steel balls (25.4 mm in diameter AISI 420) under NH3 atmosphere at 300 kPa. e weight ratio of the steel balls to B powder is 50:1. e…
