Scientific reports 11 1, 8869 (2021)
Juxtacellular interactions play an essential but still not fully understood role in both normal tissue development and tumour invasion. Using proliferating cell fronts as a model system, we explore the effects of cell–cell interactions on the geometry and dynamics of these one-dimensional…

Electrochemical phenomena in ferroelectrics are of particular interest for catalysis and sensing applications, with recent studies highlighting the combined role of the ferroelectric polarisation, applied surface voltage and overall switching history. Here, we present a systematic Kelvin probe…

La physique des systèmes élastiques désordonnés permet d’étudier des systèmes très variés, tel que les côtes des îles anglo-saxonnes érodées par le temps, des fissures se propageant dans le granite, les parois de domaine dans les matériaux ferroïcs, et les fronts cellulaires en…

Physical Review Letters 126 117606 (2021)
Ferroelectric materials provide a useful model system to explore the jerky, highly nonlinear dynamics of elastic interfaces in disordered media. The distribution of nanoscale switching event sizes is studied in two Pb(Zr0.2Ti0.8)O3 thin films with different disorder landscapes using piezoresponse…

Understanding and controlling the motion, stability, and equilibrium configuration of ferroelectric domain walls is key for their integration into potential nanoelectronic applications, such as ferroelectric racetrack memories. Using piezoresponse force microscopy, we analyze the growth and…

Ultramicroscopy 228 113345 (2021)
Research in materials science increasingly depends on the correlation of information from multiple characterisation techniques, acquired in ever larger datasets. Efficient methods of processing and storing these complexdatasets are therefore crucial. Reliably keeping track of data processing is…
