Nanomaterials are any type of material of nanosized thickness, i.e. less than 100 nm in thickness. There are various types, many of which exhibit different properties than bulk materials.
By Ibtisam AbbasiReviewed by Lexie CornerUpdated on Oct 15 2024 Nanomaterials are defined as functional substances with at least one dimension between 1 and 100 nm and a specific surface area by volume greater than 60 cm2/cm3.1 They are used in a wide range of fields, including medicine, electronics, environmental remediation, and renewable energy.2 What Is a Nanomaterial? Nanotechnology is no longer a novel concept; it has evolved into a general-purpose technology.
Quantum Dots Quantum dots are less than 10 nm in size and typically consist of a core made from semiconductor material and a shell made from a different material that acts as a surface passivation layer. Fullerenes are excellent conductors of electricity and heat, exhibiting remarkable tensile strength. While chemically stable, they are not entirely inert and can act as electrophiles in chemical reactions.
CNTs can be categorized into two regions: the sidewall and the tip. The tip resembles the structure of a fullerene hemisphere, making it more reactive.9 Depending on the number of concentric tubes in their structure, CNTs are classified as single , double, or multi-walled . Silicon–carbon nanowires, produced through simulation methods, have shown single-crystalline hexagonal structures and high tensile strength. However, synthesizing nanowires in a highly reproducible manner remains a significant challenge.11
How are MXene Nanomaterials Synthesized? MXenes MXenes are two-dimensional materials derived from layered transition metal carbides, nitrides, or carbo-nitrides, created by selectively etching their parent MAX phases. Quantum dots, characterized by higher electron mobility, are ideal for high-performance computing platforms and computer hardware. They are also utilized in photonic applications due to their high efficiency.6
