Nanoscience

Nanoscience is a branch of interdisciplinary that studies materials, structures, and processes at the nanometer scale (between 1 and 100 nanometers). This field, which forms the foundation of nanotechnology, brings together many different scientific disciplines including physics, chemistry, biology, engineering, and materials science. Nanoscience involves research into how materials behave at the atomic and molecular levels, and these studies enable the development of new materials and technologies opportunity.

Historical Development

The concept of nanoscience was first proposed theoretically in 1959 by famous physicist Richard Feynman in his lecture titled "There's Plenty of Room at the Bottom". However, the practical advancement of nanoscience gained momentum with the discovery of the scanning tunneling microscope (STM) and atomic force microscope (AFM) in the 1980s speed.

During the 1990s, with the rise of nanotechnology, scientists discovered new nanomaterials such as nanoparticles, nanotubes and graphite. By the 2000s, nanoscience had expanded to a wide range of applications, from drug delivery systems to electronic devices. Today, nanoscience is used in areas such as artificial intelligence-assisted material design, biomedical research and energy storage.

Pioneers and Contributions in Nanoscience

Scientists who have made significant contributions to the field of nanoscience include:

• Richard Feynman: The scientist who first proposed the concept of nanotechnology theoretically.

• Gerd Binnig and Heinrich Rohrer: They pioneered experimental nanoscience by discovering the scanning tunneling microscope in 1981.

• Sumio Iijima: He initiated a new era in nanomaterials by discovering carbon nanotubes in 1991.

• Andre Geim and Konstantin Novoselov: They made one of the most important discoveries in nanoscience by isolating graphene in 2004.

Basic Principles

Nanoscience is based on fields such as quantum mechanics and surface chemistry. Its fundamental principles include:

• Quantum Effects: At the nanoscale, quantum effects become prominent, causing materials to exhibit properties different from their macroscopic counterparts.

• Surface-to-Volume Ratio: Due to their small size, nanomaterials have a higher surface-to-volume ratio, leading to different reaction mechanisms in catalysts and biological systems.

• Specialized Fabrication Techniques: Top-down and bottom-up methods are used to produce nanomaterials.

• Property Changes at the Nanoscale: Materials can exhibit different chemical and physical properties at the nanoscale. For example, gold can appear in different colors and gain catalytic properties when reduced to nanoscale dimensions.
