An alternative to cotton: bulrush Cotton cultivation and production of cotton has a major, negative impact on the environment. This is mainly due to the land and water use, the amount of pesticides that are used and the CO2 emissions released during transport. That may be different, with bulrush (reed cigar).

New technology sees difference between twelve different types of plastic A Danish research project has led to the development of a new camera technology to see the difference between twelve different types of plastic and to sort plastic based on chemical composition.

Super jelly Researchers at Cambridge University (UK) have developed a jelly-like material that, although 80 percent water, can withstand the pressure of an elephant if it were to step on it.

Constructive reliability of biobased building materials Within the framework of the so-called BRIC project (Biobased Renewable Innovative Constructions), Avans University of Applied Sciences is carrying out accelerated aging tests of the circular biobased biocomposite profiles developed by the project partners.

New vegetable composite: tough as bone and hard as aluminum Wooden cell walls are made up of cellulose fibers. Within each fiber are reinforcing cellulose nanocrystals, (cellulose nanocrystals or CNCs): chains of organic polymers arranged in near-perfect crystal patterns. A team of MIT team developed a composite with a high percentage of CNCs, which could also be deformed well.

ADVERTORIAL

Special quartz glass with Sol-Gel technology The Sol-Gel method works by gelling a liquid with SiO2 at room temperature, which is then poured into the desired shape. After drying in the mould, it is removed. The product formed is then further dried in a conditioned drying oven. Finally, the product is sintered at a temperature of approximately 1400 °C. During sintering, the product compacts to the required dimensions. This results in a shrinkage of 50%. In this way both transparent and opaque and black quartz glass can be made. IQS GmbH in Ilmenau has further developed and refined the process with Sol-Gel. They have succeeded in developing three types of quartz glasses with special properties.

Transparent The first type is the transparent Verusil; a synthetic quartz glass with a very high chemical purity. Verusil has an OH content of 300 ppm. Verusil is mainly used in optical, analytical and technical applications.

By applying an extra step in the purification process, the chemical contamination of Verusil can be further improved if desired and the content of OH groups can be reduced to almost zero.

ADVERTORIAL White opaque materials

The opaque Diffusil® is available in three different types, each intended for a specific application.

Diffusil®-UV is an opaque material with the highest chemical purity and the best optical homogeneity of the Diffusil® family. Only synthetic raw materials of the highest purity are used for production. Diffusil®-UV has a monomodal size distribution of small gas bubbles with a diameter of about 4 m in the material.

With their near-perfect spherical shape, these act as ideal optical scattering centers and provide an almost Lambertian scattering characteristic. The amount and size of the gas bubbles in the material can be adjusted according to customer requirements. The material is ideally suited for use as an optical diffuser in a wide wavelength range from UV to IR wavelength.

The extremely homogeneously distributed gas bubbles in the material create the opaque appearanceof Diffuse-UV . They are responsible for an almost Lambertian stray light behaviour of the material. IQS offers four different opaci-

distributed gas bubbles with a diameter of approximately 4 µm. However, the amount and size of the gas bubbles are fixed and cannot be specially adjusted.

Diffusil®-T is mainly used in high temperature applications. It is used, for example, in crucibles. Maximum working temperature (long-term) is 1050 °C.

Diffusil®-S is an opaque material that meets the high purity requirements for use in the semiconductor industry. It contains a higher number but significantly smaller gas bubbles of approximately 4 µm compared to other competing materials. This results in improved thermal and optical properties of this material.

Its high reflectivity to infrared radiation makes it the ideal material for use in furnace processes in the manufacture of semiconductors and solar cells.

Black Quartz Glass The third group is the recently developed Zerosil; black fused silica glass with excellent optical absorption properties.

It is manufactured using synthetic raw materials through a Sol-Gel process.

Zerosil combines the high chemical purity with the excellent optical and thermal properties. Zerosil has a uniform black appearance. This is achieved by the finely divided, light-absorbing carbon nanoparticles of approximately 100 nm diameter in the glass.

Zerosil fused silica is mainly used in optical and thermal applications.

Diffusil®-T is manufactured from a mix of synthetically produced raw materials and raw materials of natural origin using a special Sol-Gel process. Due to the special mix of raw materials, it can be used especially in higher temperature ranges, because the softening point is higher. Diffusil®-T also contains evenly

Innovative Materials, the international version of the Dutch magazine Innovatieve Materialen, is now available in English. Innovative Materials is an interactive, digital magazine about new and/or innovatively applied materials.

Innovative Materials provides information on material innovations, or innovative use of materials. The idea is that the ever increasing demands lead to a constant search for better and safer products as well as material and energy savings. Enabling these innovations is crucial, not only to be competitive but also to meet the challenges of enhancing and protecting the environment, like durability, C2C and carbon footprint.

By opting for smart, sustainable and innovative materials constructors, engineers and designers obtain more opportunities to distinguish themselves.

As a platform Innovative Materials wants to help to achieve this by connecting supply and demand.

Innovative Materials is distributed among its own subscribers/network, but also through the networks of the partners. In 2019 this includes organisations like M2i, MaterialDesign, 4TU (a cooperation between the four Technical Universities in the Netherlands), the Bond voor Materialenkennis (material sciences), SIM Flanders, FLAM3D, RVO and Material District.
