  • Title of Project: Investigating The Physical Properties and Application of Quantum Dots

  • PREPARED BY: Chiaxan Adnan Haji

  • SUPERVISED BY: Prof. Dr. Azeez A. Barzinjy

  • ABSTRACT
    Nanomaterials refer to materials with dimensions ranging between 1 and 100
    nanometers. They have transformed numerous research domains owing to their
    distinctive optical, electronic, and other characteristics. Among these nanostructured
    materials. the materials that range from 2 to 10 nanometers are known as quantum
    dots. Quantum dots are notable due to their high surface area-to-volume ratio, surface
    plasmon resonance, and quantum confinement effects. The term “quantum dot” stems
    from their extremely diminutive size, resembling a single point or dot, hence termed as
    zero-dimensional material. Usually, a few dozen to a few thousand atoms make up a
    quantum dots. Consequently, they hold significant promise for a wide array of
    applications across various fields. This study is structured into three sections. Firstly, it
    covers the fundamental principles of quantum dots. The subsequent section delves into
    diverse synthesis methods for quantum dots, encompassing techniques such as
    hydrothermal, sol-gel, coprecipitation, laser ablation, biogenic, microwave-assisted, and
    sonochemical. In the last section, many uses for quantum dots are discussed, including
    photocatalysis, solar energy, light-emitting diodes, sensors, water photo-splitting,
    targeted medication delivery, cancer treatment, and more. It is foreseeable that quantum
    dots will soon establish themselves as transformative particle, heralding remarkable
    advancements in the years ahead.

  • ABSTRACT
    Self-healing materials have attracted a lot of attention recently because they offer
    the potential to increase product dependability and safety while also extending product
    lifespans and reducing replacement costs. The development of self-healing materials has
    revolutionized material science and engineering by providing answers for durability and
    structural integrity. Self-healing alloys stand out among these as great choices for a variety
    of applications. Systems that can heal themselves can be made from a variety of polymers,
    ceramics, and metallic materials. This page examines the various aspects of self-healing
    alloys, including their kinds, compositions, workings, and uses. We start by giving a brief
    overview of self-healing materials and stressing their importance in reducing structural
    damage and lengthening material life. Next, we classify self-healing alloys according to
    their composition (from metal matrix composites to shape memory alloys), and we talk
    about their special qualities and their uses.
    Keywords: smart materials, self-healing alloys, and self-healing effect.
