HYPERFINE 2021 in Brasov will adopt a program similar to those of previous meetings in this series. The program will be built up around presentations from topics including, but not limited to:

• Hyperfine interactions and nuclear quadrupole interactions
• Radioactive ion beams, radioisotope probes and ion-solid interactions
• Nuclear moments, nuclear polarization and nuclear models
• Nuclear magnetic resonance (NMR), Nuclear quadrupole resonance (NQR), Electron spin resonance (ESR) and applications
• Low temperature nuclear orientation, Perturbed angular distribution, Perturbed angular correlations, Mössbauer and muon spin spectroscopies
• Resonance methods
• Synchrotron radiation, X-ray, inelastic and elastic neutron scattering and other complementary techniques
• Metals, insulators and semiconductors
• Magnetism, magnetic materials and superconductivity
• Nanomaterials
• Lattice and defect dynamics
• Surfaces, coatings, interfaces, thin films, hybrid materials and nano-structures
• Theoretical methods for hyperfine field calculations
• Applications in biology, chemistry, medicine, engineering and geoscience
• New developments and future directions
