Materials sciences - an interdisciplinary research field

Materials sciences involves the research, development, characterization, manufacture and processing of materials.

Materials sciences- the basis

As an interdisciplinary field, materials sciences encompasseschemistry, physics, mineralogyand many other areas of science. As a result, it is also tied closely to copper, iron and steel.

The transition from natural materials such as stone, wood, ivory or leather to the targeted production of materials such as copper, steel or iron

.

Copper, steel and iron were produced as early as the Neolithic, roughly around 4,300 B.C. Copper and iron were produced as far back as the New Stone Age, roughly 4,300 B.C. This was then followed by the transition to the Bronze Age. It wasn't until the Iron Age that apart from iron, steel and copper, aluminum was also produced using the Hall-Héroult process. For a long time, materials sciences was interested almost exclusively in metals such as iron, copper and steel. However, this has changed with the rediscovery of concrete. While the first, mass-produced plastic materials eventually attracted the interest of the broad public, materials sciences continues to carry out research into iron, copper and steel.

The first metals and the ancient times

Copper, steel and iron were the first metals that mankind became familiar with as it evolved. Copper is very easy to process. As a result, copper was already being used 10,000 years ago by the oldest known cultures 10,000. The era of large-scale copper use (between 3,000 and 5,000 B.C.) is referred to as the Copper Age. The devotees of alchemy associate copper with Venus, the symbol of femininity. The first mirrors were even made from copper. The Roman Empire was the largest producer of copper prior to the Industrial Age. Copper remains an extremely popular material.

Steel - stable and dependable

Mankind has acquired long years of practical experience with steel. Steel is a preferred material in engineering because of its durability, excellent corrosion properties and suitability for welding. It is significantly more stable than copper. The European steel registry lists more than 2,300 types of steel. Coal and steel served as the pillars of heavy industry over a long period of time and were thus the foundations of political power. Steel is defined as an iron-carbon alloy with less than 2.06 percent carbon content. Steel, or iron, has a density of 7.85-7.87 g/cm3. Steel melts at a temperature that can be as high as 1,536°C and therefore withstands much higher temperatures than copper.Steel was first produced around 1,000 B.C., much later than copper. In an ecological sense, steel is a sustainable material because it can be continuously reused with minimal quality loss .

Iron - from decoration to general utility

The use of iron was first recorded around 4,000 B.C. in Egypt. It was a solid iron used for decorations and for making spear tips. It was more suitable for these purposes than steel or copper. Smelted iron appeared later in Mesopotamia and Egypt, but it was only intended for ceremonial purposes. Perhaps iron came about as a byproduct of bronze production. After the Hethiter developed a method to produce iron, cultures became increasingly reliant on iron between 1,600 and 1,200 B.C. Iron is thought to be a major element of the earth's core, along with nickel. Iron is produced by reducing iron ore through a chemical reaction with carbon. In contrast to steel or copper, iron is produced in blast furnaces.

Materials Sciences

Materials management deals with the research, development, manufacturing and processing of raw and industrial materials. Key aspects here are biological and medical issues, which play an increasingly important role in this field.

New mechanical metamaterials can block symmetry of motion, findings suggest

Engineers and scientists at The University of Texas at Austin and the AMOLF institute in the Netherlands have invented the first mechanical metamaterials that easily transfer motion effortlessly in one direction while blocking it in the other, as described in a paper published on Feb. 13 in Nature. The material can be thought of as a mechanical one-way shield that blocks energy from coming in but easily transmits it going out the other side.

The researchers developed the first nonreciprocal mechanical materials using metamaterials, which are synthetic materials with properties that cannot be found...

Research published Wednesday, in Nature Scientific Reports lays out a theoretical map to use ferroelectric material to process information using multivalued logic - a leap beyond the simple ones and zeroes that make up our current computing systems that could let us process information much more efficiently.

The language of computers is written in just two symbols -- ones and zeroes, meaning yes or no. But a world of richer possibilities awaits us if we could...

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
