Magnetic precession – the rotation of the magnetisation around an applied torque — seems an unavoidable obstacle to faster magnetic devices. Now, researchers at the LPS have shown that magnetic …
What is the fate of polymer debris in the ocean? Aging of polyethylene packaging after prolonged marine exposure as been tracked at the nanoscale. A recent work demonstrates that the …
The most common technology used nowadays in displays and screens is based on the properties of « nematic » liquid crystals. The existence of two new types of nematic liquid crystals was …
Catherine Even, associate professor at LPS, has just published a book with Nicolas Vernier that presents thermodynamics visually and applied to everyday life. In color and very illustrated, this book …
Solar cells based on mixed-halide hybrid perovskites show efficiencies that have already surpassed the best polycrystalline silicon-based cells, in just a few years since their discovery 1Y. Fu, H. Zhu, …
Frozen water can take on up to three forms at the same time when it melts: liquid, ice and gas. This principle, which states that many substances can occur in …
An LPS team has just observed the shear of a charge density wave under an applied electric current by scanning X-ray diffraction. A charge density wave is a state which …
Researchers from the LPS and their collaborators have experimentally identified a new regime in Josephson junctions illuminated by microwave radiation. They found that high-frequency and high-power microwaves change the transport …
Macroscopic assembly of nanomaterials in fibers can improve their mechanical characteristics and add new functions. One-dimensional nanomaterials are particularly suited to the uniaxial geometry of fibers. Researchers at Imperial College …
Spontaneous electric polarization, a phenomenon called ferroelectricity, occurs in a material when the spatial distributions of positive and negative charges differ. It is therefore intimately related to the symmetry of …
