Materials Chemistry Literature Review

Introduction

Materials chemistry is a branch of chemistry that deals with the synthesis, characterization, and application of materials. It is a relatively new field, but it has already had a major impact on our lives. Materials chemists have developed new materials that are used in everything from electronics to medicine to energy storage. This literature review will explore key advancements and trends in the field.

Key Concepts

Some of the key concepts in materials chemistry include:

  • Synthesis: The process of creating new materials, including techniques like sol-gel processing, chemical vapor deposition (CVD), and hydrothermal synthesis. Different synthesis methods lead to materials with varying properties and morphologies.
  • Characterization: The process of determining the properties of a material using techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), nuclear magnetic resonance (NMR) spectroscopy, and various other spectroscopic and microscopic methods. These techniques provide information about the material's structure, composition, and morphology.
  • Application: The use of a material for a specific purpose, ranging from structural materials in construction to advanced functional materials in electronics and medicine. The application often dictates the desired properties of the material and the synthesis methods employed.

Recent Advances and Trends

Recent years have witnessed significant advancements in materials chemistry, particularly in the areas of:
