Materials science is an interdisciplinary field involving the properties of matter and its applications to various areas of science and engineering. It includes elements of applied physics and chemistry, as well as chemical, mechanical, civil and electrical engineering. With significant media attention to nanoscience and nanotechnology in the recent years, materials science has been propelled to the forefront at many universities, sometimes controversially. In materials science, rather than haphazardly looking for and discovering materials and exploiting their properties, one instead aims to understand materials fundamentally so that new materials with the desired properties can be created. The basis of all materials science involves relating the desired properties and relative performance of a material in a certain application to the structure of the atoms and phases in that material through characterization.

The year 2020 marks 100 years since Hermann Staudinger first published the concept of polymerization in 1920. Polymers have revolutionized the way we live ever since. Therefore, the journals Advanced Materials, Advanced Healthcare Materials, Advanced Energy Materials, and Angewandte Chemie are helping to celebrate this anniversary by looking at past and present achievements published in all of our journals. We cover the subject with four virtual issues, updated throughout the year, that highlight the following facets of polymer science: Technology, HealthCare, Sustainability, and Chemistry.

Nanoengineering is the engineering field focused on the study, development and refinement of materials at a very small scale. It can be thought of as the practical application of nanoscience, similar to how mechanical engineering applies the principles of physics. The word “nano” is derived from a Greek word meaning “dwarf” and denotes one one-billionth (i.e., 10^-9) of the the unit in question. For context, a human is almost one hundred thousand nanometers wide and a strand of DNA is typically less than three nanometers in diameter.

A man-made product that small — tinier even than a bacterium — might not seem like it would be substantial or strong enough to make any difference in the real world. However, like the similarly nanoscale DNA strands noted above, nanomaterials deployed en masse have a profound effect. A vast range of products, from tennis rackets to antibacterial bandages, incorporate nanomaterials. Nanoenginners direct the manufacturing of these nanomaterials via multiple techniques such as electron beam lithography and micromachining.

Material science understanding is a key factor to consider in drug substance and drug product process development. The material properties for the API, excipients, and intermediates can influence the process and product performance. This session focuses on the application of material science to guide drug substance and drug product development. Of particular interest is work related to elucidate key material attributes impacting process and product performance as well as the application of the novel material property tool or data to gain further process understanding.

Sensor technology has advanced exponentially in the past few decades. In this trend, the discovery and development of electroactive polymers can be considered a breaking point in this field. Also, the combination of materials with the development of nanotechnology was able to produce miniaturized devices with superior sensing properties. This chapter is presented in the following order: first, an introductory section seeks to explain the basic vocabulary and the essential concepts for organic-based sensors. After, the main phenomena that involve the use of organic polymers in sensors, especially chemical sensors, are presented. The third part highlights the main characteristics of conducting polymers associated with technological development in chemistry, physics, and engineering and how it enabled many sensors. Next, in the fourth part, examples of organic polymer applications through relevant literature reports are presented. Finally, some challenges from human society are highlighted where sensor and biosensor technology new developments are essential.

Smart materials also called intelligent or responsive materials, are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, moisture, electric or magnetic fields, light, temperature, pH, or chemical compounds. Smart materials technology enables us to adapt to environmental changes by activating its functions. Smart materials for active coating transport the sensing and responding properties to textiles by traditional coating technologies. These bio inspired materials can change their dimensions, solubility, color, and shape, etc., upon a specific trigger.

Smart materials technology enables us to adapt to environmental changes by activating its functions. Multifunctional materials, sort of smart materials, can be activated by electrical stimuli so as to produce its geometry change or property change. There are many multifunctional materials available by the advent of nanotechnology, ranging from carbon nanotubes, graphene, inorganic nanoparticles, conducting polymers, and so on. However, future multifunctional smart materials should be harmonized with our living environment. Thus, it is natural to develop smart materials that can be renewable in the nature. Biopolymers are renewable materials that harmonize with environment.

For the repair or reshape of the mutilated tissue, Nanotechnology can be used as part of Tissue Engineering by the usage of suitable Nanomaterial-based scaffolds and growth factors. If it is victorious then tissue engineering may replace conventional treatments like organ transplants. For bone tissue engineering applications, Nanoparticles such as carbon Nanotubes, graphene, carbon Nano cones and tungsten disulfide are used as reinforcing agents to manufacture mechanically strong biodegradable polymeric Nano composites.

Corrosion is the deterioration of a material as a result of its interaction with its surroundings and can occur at any point or at any time during petroleum and natural gas processing. Although this definition is applicable to any type of material, it is typically reserved for metallic alloys. Furthermore, corrosion processes not only influence the chemical properties of a metal or metal alloys, but also generate changes in their physical properties and mechanical behaviors.

Smart ceramics are the materials fabricated from ultrafine particles. They are hard, brittle, heat-resistant and corrosion-resistant materials made by shaping and then firing an inorganic, non-metallic material, nitride, or carbide material such as clay, at a high temperature. Ceramography is the art and science of preparation, examination, and evaluation of ceramic microstructures.
