Recently, it is pursued to give cultured cells such complex structures as body tissues contain in themselves. At the first step of this research, we synthesized Thermo-Responsive Cell Culture Membranes (n-TRCCMs) by electron beam graft polymerization. Then, we fabricated Si molds with microstructures (Line & Space) by photolithography process and obtained patterned Thermo-Responsive Cell Culture Membranes (p-TRCCMs) by imprinting the Si molds on n-TRCCMs. In cell culture experiments, it was confirmed that cells adhered to p-TRCCMs and proliferated along the patterns on them.
The μSR spectroscopy is an important method to study the microscopic and dynamic nature of magnetic materials. In this article, after an introduction, several examples of μSR studies carried out on the spin-frustrated magnets are introduced.
Muon is an elementary particle that belongs to the second-generation lepton with spin 1/2. Spin of muon interacts with electro-magnetic fields through dipole moments. A precise prediction on magnetic dipole moment of muon is possible by using the standard model of particle physics. The electric dipole moment is estimated to very small under the standard model. Precision measurements of these dipole moments of muon and its comparison to theory allow us to study new physics phenomena beyond the standard model of particle physics. Measurements of muon dipole moments and underlined physics are reviewed in this paper.
