A polymer-based textile thermoelectric generator for wearable energy harvesting KU Leuven

Anja Lund, Yuan Tian, Sozan Darabi, Christian Müller
Conducting polymers offer new opportunities to design soft, conformable and light-weight thermoelectric textile generators that can be unobtrusively integrated into garments or upholstery. Using the widely available conducting polymer:polyelectrolyte complex poly (3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) as the p-type material, we have prepared an electrically conducting sewing thread, which we then embroidered into thick ...

Preclinical effectiveness of an experimental tricalcium silicate cement on pulpal repair. KU Leuven

Xin Li, Mariano N. PEDANO DE PIERO, Shuchen Li, Zheyi Sun, Charlotte Jeanneau, Imad About, Esther Hauben, Zhi Chen, Kirsten Van Landuyt, Bartholomeus Van Meerbeek, et al.
OBJECTIVES: To investigate the pulpal repair potential of an experimental zirconium-oxide containing tricalcium-silicate cement, referred to as 'TCS 50'. MATERIALS AND METHODS: The effect of TCS 50 on viability, proliferation, migration, and odontoblastic differentiation of human dental pulp cells (HDPCs) was assessed using XTT assay, in-vitro wound healing assay and RT-PCR, respectively. Additionally, the pulp-capping potential was evaluated ...

Unravelling stacking order in epitaxial bilayer MX2 using 4D-STEM with unsupervised learning. KU Leuven

Ankit Nalin Mehta, Nicolas Gauquelin, Magnus Nord, Andrey Orekhov, Hugo Bender, Dorin Cerbu, Johan Verbeeck, Wilfried Vandervorst
Following an extensive investigation of various monolayer transition metal dichalcogenides (MX2), research interest has expanded to include multilayer systems. In bilayer MX2, the stacking order strongly impacts the local band structure as it dictates the local confinement and symmetry. Determination of stacking order in multilayer MX2 domains usually relies on prior knowledge of in-plane orientations of constituent layers. This is only feasible ...

Growth of a self-assembled monolayer decoupled from the substrate: nucleation on-command using buffer layers KU Leuven

Robby Reynaerts, Kunal Mali, Steven De Feyter
Structural polymorphism is ubiquitous in physisorbed self-assembled monolayers formed at the solution–solid interface. One of theways to influence network formation at this interface is to physically decouple the self-assembled monolayer from the underlyingsubstrate thereby removing the influence of the substrate lattice, if any. Here we show a systematic exploration of self-assembly ofa typical building block, namely 4-tetradecyloxybenzoic acid ...

Effect of organic additives in fluoacid-based Ti and Zr-treatments for galvanized steel on the stability of a polymer coated interface Vrije Universiteit Brussel

L. I. Fockaert, M. V.E. Ankora, Sven Pletincx, A. Yilmaz, B. Boelen, Tom Hauffman, Y. Garcia-Gonzalez, Herman Terryn, J. M.C. Mol

The bonding properties of zirconium- and titanium-based conversion coatings were evaluated using model conversion solutions of H2ZrF6 and H2TiF6 with addition of various organic additives (PAA, PVA, PVP). Macroscopic testing techniques such as contact angle and pull-off adhesion measurements were performed on galvanized steel sheets. Complementary to this, molecular studies were performed on model zinc substrates using ATR-FTIR in the ...

Near-field Terahertz Sensing of HeLa Cells and Pseudomonas Based on Monolithic Integrated Metamaterials with a Spintronic Terahertz Emitter KU Leuven

Zhongyang Bai, Yongshan Liu, Ruru Kong, Tianxiao Nie, Yun Sun, Helin Li, Tong Sun, Chandan Pandey, Yining Wang, Haoyi Zhang, et al.
Label-free biosensors operating within the terahertz (THz) spectra have helped to unlock a myriad of potential THz applications, ranging from biomaterial detection to point-of-care diagnostics. However, the THz wave diffraction limit and the lack of emitter-integrated THz biosensors hinder the proliferation of high-resolution near-field label-free THz biosensing. Here, a monolithic THz emission biosensor (TEB) is achieved for the first time by ...
