Graphene-based devices for biological sensing Tekijä Kaaripuro, Henri

“…I(D/)I(G) was found to depend somewhat linearly on irradiation parameters, laser pulse energy and irradiation time. The height of the oxidized squares was found to increase nonlinearly as I(D)/I(G) did, as expected, but it was also noted to be affected by the size of the irradiated area. …”

Studies of neutron-rich nuclei by proton induced fission Tekijä Huhta, Mika

“…Also, the beam quality of the IGISOL-mass separator was studied using the collinear laser spectroscopy method. In addition, the independent yields for n-rich nuclei produced in 25 MeV proton-induced fission in ⁿᵃᵗU or ⁿᵃᵗTh in the mass region A ≈ 70 - 145 were studied. …”

New features in systematics of low-spin states in even 106−120Cd Tekijä Kumpulainen, Jaana

“…Low-lying low-spin collective states in even 106,108,110,112,116Cd were investigated by means of in-beam and off-beam γ-ray and conversion-electron spectroscopy. New spin assignments and decay branching ratios for the levels in 106Cd, 108Cd, 110Cd and 112Cd were obtained. …”
