The first is performed while printing a 3D Ti6Al4V during xray diffraction. It allows to track with a time resolution of 50µs the dynamics of the α and β phases during fast heating and solidification, providing the cooling rates of each phase and the duration the β phase exists [Hocine et al, Mat Today 34(2020)30; Add Manuf 34(2020)101194 ; Add Manuf 37 (2021)101747]. The second is an operando experiment carried out on a thin Ti6AlV wall while remelting the surface. It allows quantification of the thermal cycles experienced by the material along the building direction [Ming et al, submitted].

From prototyping to flight hardware manufacturing and looking into the the future toward out-of earth manufacturing, this talk aim to expose the different aspect of polymer 3D printing (FFF/FDM) for space application. The European Space Agency is looking into the implementation and use of new materials to enable new applications for space. Polymers and polymer composites specially are part of such focus among others. However, the benefit of new functionalities or capabilities brought by materials shall be assessed against their behaviour under the effect of space environment. Effect of space environment (VUV, Thermal Cycling, ATOX) on the functional performance of advanced thermoplastics materials (PolyEtherEtherKetone-PEEK) focusing on electrically conductive PEEK processed by additive manufacturing will be presented. The results obtained on this material mechanical, optical and electrical performances be presented including demonstrator enable by such material and process combination. The effect of the process and its relation with the material on the final part performance will be discussed as well showing the importance of having a standardised approach to enable accurate part qualification. The recent advances on the use of 4D printing concepts suitable for space application will be exposed and discussed with an emphasis on the role of meso-structuration. Last, the results presented and the role of materials in the implementation and development of out-of-earth / In-space manufacturing capabilities will be put in perspective against the current state-of-the-art and available technologies. <span style="background-color:initial">​</span></li></ul> <br /></div> <div><ul><li><b>3D Bioprinted Human Tissue Models for Pharmaceutical and Cosmetic Product Testing<br /></b><a href="https://www.cellink.com/global/faces-bioprinting-meet-cellink-scientific-officer-bite-team-leader-itedale-namro-redwan/"><img src="/en/areas-of-advance/materials/Calendar/PublishingImages/MFT_Itedale_Namro_Redwan.jpg" alt="Itedale Namro Redwan" class="chalmersPosition-FloatRight" style="margin:5px" />I<span style="background-color:initial">t</span><span style="background-color:initial">edale Namro Redwan</span></a><span style="background-color:initial">, PhD.

The monomeric ink is extruded from a print head onto a heated bed triggering the frontal polymerization (FP) reaction. Heat released from the polymerization activates adjacent monomer to further the curing process, thereby forming a self-sustaining propagating reaction wave that polymerizes the printed filament. The stiff polymerized segment of the filament can structurally support the printed part during its fabrication to produce three-dimensional (3D) free form printed structures with excellent fidelity. Fabricated parts exhibit a degree of cure of 99.2% and do not require further post-processing.  The addition of nanoparticles and other reinforcement phases allows access to a range of rheological profiles between low-viscosity liquid and free-standing elastomeric gel – all of which frontally polymerize upon thermal activation. This presentation will summarize the characterization of ink rheology for printing, influence of printing parameters, addition of reinforcing fillers, and the resulting mechanical properties of the printed structures.</span></li></ul></div> <div><br /><br /><a href="https://ui.ungpd.com/Surveys/e19f2bbb-3ee3-4e2f-b259-173b334d614a" style="outline:0px"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Register to the seminar </a><br /></div> <br /><span style="background-color:initial"></span><div><span style="background-color:initial;font-family:inherit;color:rgb(33, 33, 33);font-size:20px">A</span><span style="background-color:initial;font-family:inherit;color:rgb(33, 33, 33);font-size:20px">bout Materials for Tomorrow</span><br /></div> <div> <p style="margin-bottom:10px"><a href="/en/areas-of-advance/materials/news-and-events/Materials-for-Tomorrow/Pages/Materials-for-Tomorrow-2019.aspx">​</a>Materials for Tomorrow is an annual conference - started in 2010 - covering research, education and innovation in materials science.

With LEDs and lasers based on the ultra-wide bandgap semiconductor AlGaN a new age of UV technology and applications is dawning. However, developing semiconductor-based UV light-emitters requires a holistic approach. Therefore, we have joined forces between material physicists at TU Berlin and device physicists at Chalmers, creating energy efficient UV light-emitting diodes (LEDs) and the world’s shortest emission wavelength from a vertical-cavity surface-emitting laser (VCSEL). <br /><br /><strong>Why should we care about UV light-emitters?</strong><br />With the ongoing pandemic the need for disinfection is now even more important than ever. UV illumination has proven efficient in sterilizing SARS-CoV-2, but also other virus and bacteria, making it an important tool to combat future pandemics, but also to provide clean drinking water. UV illumination is also of great use for other applications such as promoting healthy substances in plants, dermatological phototherapy, curing of materials, gas sensing etc. <div><br /></div> <div><strong>Why UV LEDs and lasers? What are the challenges?</strong><br />Today, UV illumination is often provided by mercury-based UV lamps. By replacing them with semiconductor-based UV LEDs and lasers the light source will become environmentally friendly, have a small form factor (µm-sized instead of cm-m sized) and be tailorable in wavelength. However, the development of semiconductor-based UV light sources has been limited by material challenges such as high defect densities, low electrical conductivity, and low optical transparency. On top of this, device concepts used for high-performing visible and infrared emitters are not that easily implemented for UV devices. Therefore, UV LEDs suffer from a poor power conversion efficiency that is typically below 10% and VCSELs with an emission wavelength shorter than UVA did not existed a short while ago. <br /><br /><strong>What has been achieved? What does the future hold?</strong><br />Low defect density and highly conductive UV-transparent device structures have been demonstrated using short-period superlattices, and more recently tunnel junctions. To boost the light extraction efficiency in LEDs and enable VCSELs with highly reflective mirrors, we have developed a substrate removal technique based upon selective lateral electrochemical etching. When the substrate has been removed, the LED surface can be roughened, which increases the light extraction efficiency by about 25%. Instead of roughening the surface, we can form a laser cavity by depositing high-reflectivity dielectric mirrors on both sides. This resulted in the world’s shortest emission wavelength from a VCSEL at 310 nm. By combining advanced material growth and innovative device fabrication we have pushed these devices forward, but this is only the beginning. If you join this seminar, we will also reveal what at we think the future holds.   </div> <div><br /></div> <div><div><br /></div> <div></div></div> <div><br /></div></div>https://www.chalmers.se/en/areas-of-advance/materials/Calendar/Pages/Materials-for-futures-batteries.aspxhttps://www.chalmers.se/en/areas-of-advance/materials/Calendar/Pages/Materials-for-futures-batteries.aspxTandem Webinar – Materials for future batteries<p></p><p>​​Welcome to our Tandem Webinar hosted by Chalmers Area of Advance Materials Science.  When: 25 November 2021, at 11 am.

For 1D nanomaterials their natural embodiment is as aligned fibres or fabrics that efficiently exploit the axial properties of their constituents. We work with a method to produce macroscopic solids made of 1D nanostructured directly collected as they grow floating in the gas phase. The resulting ensembles are “macromolecular” networks with many superior properties compared to monolithic materials: fibers of carbon nanotubes have tensile mechanical properties above many high-performance polymer fibers; fabrics of CNTs are ideal built-in porous current collectors to eliminate electron resistance limitations in composite battery electrodes, sheets of silicon nanowires are flexible and have high cyclability as lithium-ion battery anodes. </div> <div style="font-size:14px"><br /></div> <div style="font-size:14px"><span style="font-weight:700">Juan J.

Multifunctionality, for instance integrating energy storage capabilities to structural components, is a key enabling technology in realizing substantial weight savings on the system level. Carbon fibres are widely used as reinforcements in polymer composites, while graphite powders are widely used as negative electrodes in batteries. Thus, using carbon fibres as negative electrodes, together with solid electrolyte and other components, one can build the so-called structural composite batteries. Imaging the doors and hoods of an electric car also store energy! However, almost all carbon fibres were developed from the mechanical point of view; a fundamental understanding on the behaviour of carbon fibres under the dynamic electrochemical and mechanical processes in structural composite batteries, and on the relationship between their performance and microstructure are still largely lacking. We aim to gain a fundamental understanding of carbon fibres in the multifunctional composites.</div> <div style="font-size:14px"><br /></div> <div style="font-size:14px"><span style="font-weight:700">Fang Liu</span> is Associate Professor at the Department of Industrial and Materials Science.
