WebJun 1, 2024 · One-dimensional diamond nanothread (DNT) has drawn intensive research interests and become a promising candidate for reinforcement. This paper explores the … WebAug 15, 1991 · Introduction The mechanical properties of natural diamond have been extensively researched over the past five decades [ l 3] but, whilst a considerable amount … Diamond is extremely strong owing to its crystal structure, known as diamond cubic, in which each carbon atom has four neighbors covalently bonded to it. Bulk cubic boron nitride (c-BN) is nearly as hard as diamond. Diamond reacts with some materials, such as steel, and c-BN wears less when cutting or … See more Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. It is a crystal that is transparent to opaque and which is generally isotropic (no or very weak See more Unlike hardness, which denotes only resistance to scratching, diamond's toughness or tenacity is only fair to good. Toughness relates to the ability to resist breakage from falls or impacts. Because of diamond's perfect and easy cleavage, it is vulnerable to … See more Diamond is a good electrical insulator, having a resistivity of 100 GΩ⋅m to 1 EΩ⋅m (1.0×10 – 1.0×10 Ω⋅m), and is famous for its wide See more Being a form of carbon, diamond oxidizes in air if heated over 700 °C.
