Biopolymers
The overall objective is to obtain new polymers based on hemicelluloses derived from the Risø bioethanol process. Hemicelluloses are part of the lignocellulosic stream that is fermented in a multi-step process to generate bioethanol. However, the hemicelluloses are not necessarily all utilized in this process and may be available for other high-value uses. One possibility is to chemically modify these carbohydrates to make them more amenable to further processing (e.g., extrusion). |

Development of long superconducting tapes with improved engineering properties, produced by a green processing route
A new, scalable production technology is developed in view of the continuous manufacture of second-generation high-temperature superconducting (HTS) wires with competitive production costs and improved performance. The key point resides in the simultaneous coating of both sides of the substrate, a development that will result in a near doubling of the engineering critical density. A demonstration pre-pilot plant will be built and tested with the goal of producing a 100m long wire.

McStas
The McStas neutron raytracing simulation package is a versatile tool for producing accurate neutron simulations, extensively used for design and optimization of instruments, virtual experiments, data analysis and user training.
McStas is an international software collaboration, funded at Risø DTU in 1997 and later joined by Institut Laue Langevin (ILL), the Niels Bohr Institute (NBI) and the Paul Scherrer Institute (PSI). Since its beginning, McStas has been an important part of major neutron instrumentation projects, including ISIS TS2, J-PARC, SNS and ESS.
In 2009, the sister project McXtrace was founded, allowing the same type of simulation studies with X-rays.
Please consult the official webpage at http://www.mcstas.org for further information.

Demonstration of competitiveness of Ni-reinforced HTS tapes based on bismuth cuprate compounds
The standard manufacturing processes for Bi2223 superconducting tapes (“powder-in-tube” or PIT), in which the superconducting ceramic is surrounded by a silver (Ag) sheath make this type of HTS wires rather expensive and hinder a widespread implementation of the technology. The present project aims at replacing a part of the Ag with nickel (Ni). This could be a breakthrough that has the potential of lowering the manufacturing costs of HTS wires to a level enabling their rapid penetration into the market. Additionally, the higher mechanical strength of Ni would be an important advantage for handling during manufacturing of cables.

Superior HTS coated-conductors via green processing
HTS wires based on different kinds of materials are presently being developed. However, the only class of HTS compounds suited for operation under magnetic fields are the members of the REBa2Cu3O7 family (RE = rare earth) due to their superior flux pinning ability. The so-called “coated conductors”, presently developed in view of such applications using the REBa2Cu3O7 compound, suffer mainly from a slow production rate and high manufacturing costs. Furthermore, the hazard risks inherent to some preparation steps should be avoided.

Superconductivity and magnetism research group
Superconductors have attracted major scientific interest for decades and significant contributions to technology have been foreseen, not least since the discovery of the high-temperature superconductors (HTS) in 1986, which opened for operation in high magnetic fields at temperatures above the boiling point of liquid nitrogen (77 K). |
