Open AccessTerbium-149 production: a focus on yield and quality improvement towards preclinical application
Terbium-149 (T1/2 = 4.1 h, Eα = 3.98 MeV (16.7%), 28 µm range in tissue) is a radionuclide with potential for targeted alpha therapy. Due to the negligible emission of α-emitting daughter nuclides, toxicity to he...

Open AccessThe effect of mycophenolate mofetil on podocytes in nephrotoxic serum nephritis
Mycophenolate mofetil (MMF) is applied in proteinuric kidney diseases, but the exact mechanism of its effect on podocytes is still unknown. Our previous in vitro experiments suggested that MMF can ameliorate p...

Open AccessVirtual-photon-mediated spin-qubit–transmon coupling
Spin qubits and superconducting qubits are among the promising candidates for realizing a solid state quantum computer. For the implementation of a hybrid architecture which can profit from the advantages of e...

Open AccessMagnetisation switching of FePt nanoparticle recording medium by femtosecond laser pulses
Manipulation of magnetisation with ultrashort laser pulses is promising for information storage device applications. The dynamics of the magnetisation response depends on the energy transfer from the photons t...

Open AccessLiquid-state carbon-13 hyperpolarization generated in an MRI system for fast imaging
Hyperpolarized (HP) tracers dramatically increase the sensitivity of magnetic resonance imaging (MRI) to monitor metabolism non-invasively and in vivo. Their production, however, requires an extra polarizing devi...

Open AccessClimate analogues suggest limited potential for intensification of production on current croplands under climate change
Climate change could pose a major challenge to efforts towards strongly increase food production over the coming decades. However, model simulations of future climate-impacts on crop yields differ substantiall...

A warm layer in Venus' cryosphere and high-altitude measurements of HF, HCl, H2O and HDO
ESA's Venus Express probe has been in orbit since April 2006. Eight research papers in this issue present new results from the mission, covering the atmosphere, polar features, interactions with the solar wind...

Middle atmospheric NO and NO2 observed by the Spacelab grille spectrometer
Almost 20 years after Nicolet1 suggested the presence of nitric oxide in the upper atmosphere as a source of D-region ionization by solar Lyman α-radiation, this trace species was first observed2 by the resonance...

Ocean-wide stagnation episode in the late Cretaceous
In this paper we report that marine sediment locations spread over a wide area contain evidence of an anoxic interval during the mid-Cretaceous, here called the Cenomanian–Turonian Black Shale Horizon (CTBSH)....

Blue sunlight extinction and scattering by dust in the 60-km altitude atmospheric region
Twilight data obtained photographically from a stratospheric balloon platform in the autumns of 1980 and 1981 and in the spring of 1982 are presented for blue and red light. They indicate the presence of a lig...

Stratospheric aerosols properties from Earth limb photography
Balloon-borne observation at three wavelengths of visible sunlight scattered by the Earth limb allows the determination of aerosols abundances and size distributions at various altitudes in the stratosphere. T...

Stratospheric CH4, HCl and ClO and the chlorine–ozone cycle
SINCE it was suggested1 that chlorine may influence stratospheric ozone balance, and that halocarbons can contribute significantly to the stratospheric chlorine content2–4 much attention has been paid to the subj...

Rifting and subsidence on passive continental margins in the North East Atlantic
Deep-sea drilling in the Bay of Biscay and the Rockall Plateau show that passive continental margins are characterised by the absence of seismicity and include continental shelf, continental slope and continen...

Stratospheric Nitric Oxide from Infrared Spectra
AERONOMERS have generally admitted that the abundance of nitric oxide is small in the chemosphere. Its detection and even more its measurement have been regarded as a difficult task. The importance of this spe...

Stratospheric Nitrogen Dioxide from Infrared Absorption Spectra
STRATOSPHERIC absorption due to NO2 has been identified1–3 in infrared spectra of the solar radiation recorded from balloon borne gondolas floating at mid-latitudes in the altitude range of 30 km when the solar z...
