Corrosion
Two-dimensional (2D) lateral heterojunctions of transition metal\ndichalcogenides (TMDCs) have become a reality in recent years. Semiconducting\nTMDC layers in their common H -structure have a nonzero in-plane electric\npolarization, which is a topological invariant. We show by means of\nfirst-principles calculations…

Вступ. Рентгенівські методи широко використовують для неруйнівних мікроаналітичних досліджень \nструктури та складу матеріалів з високою просторовою роздільною здатністю. Подальше збільшення \nцього показника суттєво залежить від покращення аналітичних характеристик напівпровідникових \nдетекторів, а також від застосу…
In Chapter 2 , we discuss the flaws in the fabric that upset the relationship between mankind and the natural environment. The primary flaws we deal with are one-way traffic, with examples being the use of animal feed, fossil fuels and ore; positive feedback, including the stock markets and the worldwide population gr…
Significance and Use 3.1 Implantable medical devices can be made of dissimilar metals or come into electrical contact with dissimilar metals leading to the potential for galvanic corrosion, which may result in the release of corrosion products with harmfu
Вступ. Внаслідок механічного та хімічного зносу внутрішніх поверхонь трубоподібних виробів існує необхідність створення захисних покриттів останніх, що збільшить ресурс їх використання в різних галузях промисловості. \nПроблематика. При створенні обладнання для отримання якісних захисних покриттів внутрішньої \nповерх…
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.
On page 2159, Jae-Suk Lee and co-workers investigate three kinds of bottlebrush polymethacrylates incorporated as random copolymer blocks for phase separation of polystyrene (PS) and poly(benzyl methacrylate) based-bottlebrush block copolymers (BBCPs) with an extremely low parameter. The final BBCPs displayed ordered…
Brown algae contain the highest biological activities and considered an important source of bioactive natural substances. Two algae (Padina pavonica and Turbinaria decurrens) extracted by two solvent (water and ethanol) used to study their antibacterial activity on development brown rot disease in vitro and under arti…
Chapter 3 examines the flaws in the fabric in the relationship between man and society. The main flaws are an imbalance in the Triple P, as a result of which the economy almost always prevails; the economic necessity of continuous economic – and material – growth, which cannot be sustained in the long term; and the ex…
Вступ. Для оптимізації асортименту та конструювання ковдр із заданими властивостями суттєву \nроль відіграє вибір наповнювача, зокрема його теплофізичні показники, які у різних матеріалів різняться між собою. \nПроблематика. Теплопровідність ковдр з наповнювачами протеїнового походження, зокрема вовни \nовечої, верблю…
Methanol solutions of various concentrations have been developed based on synthesized N, Nʹ- (pirazin-2-il) pyridine - 2,6-diamine ligand (N5-2pz), its linear pentanuclear of nickel string (II) [Ni5(μ5-dpzpda)4Cl2] (Ni5-N5-2pz) and tetracyclic copper complex (II) [Cu4(Hdpzpda)2(CH3COO)6] (Cu4-N5-2pz). Anticorrosion im…
Iran is rich in gas resources, which is the most important source of hydrogen production. Purification of produced hydrogen is required for use in various processes. One of the applications of hydrogen in fuel cells is that the need for hydrogen purification and carbon monoxide concentration is as low as 10ppm. This i…
In this research, copper-reduced graphene oxide (Cu-rGO), graphene-palladium (Pd-rGO) and palladium/copper-graphene (Pd/Cu-rGO) nanohybrids were prepared and used as electrode materials towards electrocatalysis of hydrazine oxidation. For this purpose, firstly, GO was prepared by modified Hummer's method. In the follo…
The Al foams made by space-holder method were physically inserted into carbon fiber reinforced plastic (CFRP) composite thin-wall tubes to obtain the composite structure of Al foam-filled CFRP composite thin-wall tubes. Quasi-static compression tests of CFRP composite tubes, Al foams and Al foam-filled CFRP composite…
Dada a importância da utilização do para-raios como equipamento de proteção no Sistema Elétrico de Potência e a necessidade de inspeções periódicas com o intuito de diagnosticar possíveis falhas e aumentar o tempo de vida útil desse equipamento, utiliza-se a componente resistiva da corrente de fuga como parâmetro de a…
Grounding grids play a fundamental role to provide safety during electromagnetic transients and reliable operation of any electrical system under normal conditions. In this context, when lightning strikes a transmission line, surge currents will propagate to the electrical substations where grounding grids must dissip…
