A group of scientists from the University of Oviedo and ALBA has been able to identify and measure for the first time the magnitudes of topological charges inside a thin ferromagnetic film, the most commonly used morphology in nanomagnetic devices. To achieve this result, the 3D magnetization inside the film was determined with magnetic tomography at MISTRAL beamline at ALBA.
The new study, published in Science Advances, identifies the role of the CCT protein, a cytosolic chaperonin, in the reorganization of the cellular skeleton involved in the immune synapse. This interaction process between lymphocytes and antigen-presenting cells is necessary for the activation of lymphocytes and determines the immune response intensity. The inner changes of the cells have been imaged thanks to the MISTRAL beamline of the ALBA Synchrotron.
A new study fruit of a collaboration between Spanish research institutions shows that cylindrical nanowires have at the center a magnetization aligned with the axis of the wire and at the surface a magnetization that describes helical lines as the barber poles. The helicity provides chirality to the magnetic configuration, and they found out that two adjacent magnetic domains having opposite chirality are more difficult to move that two adjacent domains with the same chirality. This result evidences the role of the chirality on the dynamics of the domain walls that might be used as a practical variable for magnetic data storage.
A study published in ACS Nano demonstrated the imprinting of complex 3D chirality at the nanoscale using state-of-the-art fabrication techniques and magnetic microscopy at MISTRAL beamline of the ALBA Synchrotron. The results prove the possible control of the magnetic configuration with geometrical morphologies displaying 3D chirality and open a new avenue on applied nanomagnetism. The research was the result of a multiple collaboration of scientists from Cambridge, Glasgow and Zaragoza Universities, the ALBA Synchrotron and the Lawrence Berkeley Laboratory.
A study led by researchers at Institut d'Investigació i Innovació Parc Taulí in Sabadell (Barcelona), in close collaboration with the ALBA Synchrotron, has demonstrated that the use of tricine as an adjuvant for cisplatin chemotherapy enhances drug effectiveness against cutaneous squamous cell carcinoma. This study published in PLOS ONE assesses the effectiveness of several treatments by looking at the changes in the internal structures of the cells using the MISTRAL beamline of ALBA.
