Controlling Battery Performance in Sodium–Sulfur Systems

marie-christine — Wed, 08 Apr 2026 09:10:45 +0000

Sodium–sulfur (Na–S) batteries are promising for sustainable energy storage, but their performance is often limited by operational instability. In this study, we investigate sulfurized polyacrylonitrile (SPAN) as a cathode material and show that the depth of discharge plays a critical role in battery stability.
We find that deep discharge below 1.0 V causes structural changes in SPAN, leading to the formation of soluble polysulfides. These species migrate to the sodium anode, triggering side reactions, uneven sodium deposition, and dendrite growth. As a result, the battery experiences a loss of capacity and reduced lifespan.
By limiting the discharge range, these degradation processes can be minimized, preserving both the structure of the cathode and the overall performance of the battery. This work highlights the importance of optimizing operating conditions to achieve stable and efficient Na–S batteries.

Minisymposium on Polymeric Sustainable Materials

marie-christine — Tue, 24 Mar 2026 15:45:03 +0000

The Minisymposium on Polymeric Sustainable Materials took place on 20th March 2026 at the Karlsruhe Institut of Technology.

The symposium was organized within the framework of the EPICUR University Alliance SUSPHOTOPOLY initiative – a day that brought together inspiring scientists and fresh perspectives across polymer chemistry.

The EPICUR project not only supported that all enrolled M1 students join the symposium but also 6 PhD students from IS2M were additionally supported.

Le titre de l’article est : Metal-Free Multicomponent Upcycling of Polybutadiene to Sulfonamide-Functionalized Materials

Abstract

We report a catalyst-free, one-pot method for the upcycling of liquid polybutadiene that enables simultaneous backbone editing and introduction of sulfonamide and bromine functionalities under mild conditions. This sustainable alternative to metal-catalyzed approaches, such as selenium-based methods, offers access to functional polymers with tunable thermal and interfacial properties. The introduced bromine groups enable further orthogonal modifications, exemplified by efficient azidation. Remarkably, the resulting materials display previously unreported non-conventional luminescence behavior, expanding the functional scope of upcycled commodity polymers and opening pathways toward applications in sensing, coatings, and bioimaging.

Janna Jeschke, Ph.D. student at the Institut de Science des Matériaux de Mulhouse (IS2M), Université de Haute-Alsace, has been selected as a Finalist in the 2025 International Organization for Chemical Sciences in Development (IOCD) Essay Competition – Young Voices in the Chemical Sciences for Sustainability.

The 2025 competition invited young scientists worldwide to explore the theme “From waste to wealth : how chemical sciences can sustainably transform waste into valuable products.” Janna’s essay, entitled “Wonderland Reimagined – How Functional Upcycling Unlocks the Door to Value-Added Materials,” draws inspiration from Alice in Wonderland to explore how functional upcycling can transform plastic waste into high-value materials while reducing environmental impact.

Her work emphasizes the role of surface chemistry and Post-Polymerization Modification in converting so-called “unrecyclable” plastics, such as waste tire rubber, into multifunctional adsorbents and advanced materials for sustainable applications. The essay also connects these innovations to the United Nations Sustainable Development Goals (SDGs), highlighting how chemical innovation intersects with health, equality, and environmental protection.

Janna’s essay appears in the IOCD 2025 Compendium, which features essays from 36 global finalists and seven regional winners :

Un effet de proximité plus fort que prévu dans l’impression 3D submicrométrique

marie-christine — Wed, 22 Oct 2025 10:49:26 +0000

L’impression 3D biphotonique permet de fabriquer des fibres cent fois plus fines qu’un cheveu. Des chercheurs et chercheuses ont cependant rencontré un effet de proximité plus fort que prévu, où de grosses structures influencent les plus petites en les rendant plus épaisses que souhaité. Parus dans la revue Additive Manufacturing, ces travaux indiquent que faire des pauses dans la fabrication permet de contrer cet effet, dû à la dissolution de l’oxygène.

We are currently hiring a PhD candidate as part of the Gen-Q call, which is now officially open !

The deadline for applications is Sunday 31 August at 17:00 (Brussels time).

This thesis is part of the current race to explore the properties of graphene at critical points of its band structure, specifically in the region of very high electron doping, where the van Hove singularity and then the Lifshitz transition occur.

Un des défis majeurs d’aujourd’hui ? Le stockage de l’énergie. Et là, toutes ses formes sont convoitées, qu’elle soit calorifique, chimique, électrique ou même… mécanique. Si les batteries chimiques sont bien connues, une autre piste, plus discrète et pleine de promesses, est explorée dans le projet MESAMM.
