The drug delivery across blood brain barrier (BBB) is hampered by the presence of ATP binding cassette transporters, such as P-glycoprotein (Pgp), which effluxes back into the bloodstream several drugs, e.g. anticancer agents like doxorubicin.
Photo-active metal oxide nanomaterials for water splitting
The authors develop the concept of fractal metamaterials which consist of arrays of nano and micron sized rings containing Josephson junctions which play the role of “atoms” in such artificial materials. They show that if some of the junctions have π-shifts in the Josephson phases that the “atoms” become magnetic and their arrays can have tuned positive or negative permeabilty.
Nanoporous Li3V2(PO4)3/C microspheres with enhanced lithium ion diffusion for high-rate and long-life lithium ion batteries
Nanoporous lithium vanadium phosphate/carbon (Li3V2(PO4)3/C) microspheres assembled by well-crystalline nanoparticles in carbon matrix are synthesized by the decomposition of the microflower precursor.
Stochastic processes on networks
The dynamics of emotional chats with Bots: Experiment and agent-based simulations
Quantitative research of emotions in psychology and machine-learning methods for extracting emotion components from text messages open an avenue for physical science to explore the nature of stochastic processes in which emotions play a role, e.g., in human dynamics online.
Precursor competition in focused-ion-beam-induced co-deposition from W(CO)6 and C10H8
A subtle competition between the two precursor gases used plus the sputtering effect produced by Ga-ions are invoked to explain the obtained results. Our results highlight the potential of co-deposits using FIBID but underline the necessity of a better understanding of precursor competition to further development of this approach.
