A density-temperature description of the outer electron radiation belt during geomagnetic storms [PDF]

open access: yes, 2009
Bi-Maxwellian fits are made to energetic-electron flux measurements from seven satellites in geosynchronous orbit, yielding a number density (n) and temperature (T) description of the outer electron radiation belt.

First simultaneous observations of flux transfer events at the high-latitude magnetopause by the cluster spacecraft and pulsed radar signatures in the conjugate ionosphere by the CUTLASS and EISCAT radars [PDF]

open access: yes, 2001
Cluster magnetic field data are studied during an outbound pass through the post-noon high-latitude magnetopause region on 14 February 2001. The onset of several minute perturbations in the magnetospheric field was observed in conjunction with a ...

Sacrificial strategy towards the formation of vascular‐like networks in volumetric tissue constructs

open access: yesBMEMat, EarlyView.
This mini‐review highlights the latest progress in the sacrificial template‐enabled creation of patent vascular‐like networks, which can be incorporated into volumetric tissue constructs. Such microchannel networks can provide an immediate supply of nutrition and O2 to those cells residing next to the channels.

Influence of Protonation and Iron(II) Complexation on Magnetic Interactions in Spin‐Labeled Mechanically Interlocked Molecules

open access: yesChemistry – A European Journal, EarlyView.
The study investigates the influence of protonation and Fe(II) complexation on exchange coupling and magnetic properties in a [2]‐rotaxane and its free‐axle biradicals. Mechanical bonding markedly modifies magnetic interactions, highlighting its potential for enabling the design of interlocked molecules with tunable spin states for advanced ...

Solvent Effect on Antimicrobial Hydrophilic Xerogel Coating of Medicinal Leathers in Simulated Industrial Finishing Process

open access: yesChemPlusChem, EarlyView.
Silica‐hyperbranched poly(ethylene imine) (PEI) xerogels incorporating silver nanoparticles coated titanium dioxide particles. Dual solvent dispersions of these composites enhance medical leathers′ hydrophilicity and antimicrobial properties. The nucleation of the metal ions into the dendritic polymer‘s cavities and the gel formation were inspired by ...
