Fluorine-programmed nanozipping to tailored nanographenes on rutile TiO2 surfaces
We report that activation of the carbon (C)–fluorine (F) bond is a reliable and versatile tool enabling intramolecular aryl-aryl coupling directly on metal oxide surfaces. A challenging multistep transformation enabled by C–F bond activation led to a dominolike coupling that yielded tailored nanographenes directly on the rutile titania surface. Because of efficient regioselective zipping, we obtained the target nanographenes from flexible precursors. Fluorine positions in the precursor structure unambiguously dictated the running of the "zipping program," resulting in the rolling up of oligophenylene chains. Th...

Effects of in-office bleaching agent combined with different desensitizing agents on enamel
Conclusions:The use of desensitizing agents containing fluoride, CPP-ACP, potassium nitrate or n-HAP after in-office bleaching or mixed in bleaching agent did not inhibit the bleaching effect. However, they all recovered microhardness of enamel 14 days after in-office bleaching. (Source: Dental Technology Blog)

Room-temperature cycling of metal fluoride electrodes: Liquid electrolytes for high-energy fluoride ion cells
We report a liquid fluoride ion–conducting electrolyte with high ionic conductivity, wide operating voltage, and robust chemical stability based on dry tetraalkylammonium fluoride salts in ether solvents. Pairing this liquid electrolyte with a copper–lanthanum trifluoride (Cu@LaF3) core-shell cathode, we demonstrate reversible fluorination and defluorination reactions in a fluoride ion electrochemical cell cycled at room temperature. Fluoride ion–mediated electrochemistry offers a pathway toward developing capacities beyond that of lithium ion technology. (Source: ScienceNOW)

Routine dental care: does the evidence give us something to smile about?
In thisEvidently Cochrane blog, Sarah Chapman looks at the Cochrane evidence for aspects of routine dental care. Something to smile about? Or are there big gaps …?“Are you afraid to laugh?” Goodall’s Dental Institute, 1912.Wellcome Collection.My grandmother used to tell the tale of when she was a schoolgirl, back in about 1920, and a school event to which parents were invited. Nan and her friend enjoyed a carefree afternoon without their mothers there, having avoided inviting them – the friend because her mother had white hair, and Nan because her mother had just had all her teeth taken out. There was trouble, sh...

Hierarchically porous polymer coatings for highly efficient passive daytime radiative cooling
We present a simple, inexpensive, and scalable phase inversion–based method for fabricating hierarchically porous poly(vinylidene fluoride-co-hexafluoropropene) [P(VdF-HFP)HP] coatings with excellent PDRC capability. High, substrate-independent hemispherical solar reflectances (0.96 ± 0.03) and long-wave infrared emittances (0.97 ± 0.02) allow for subambient temperature drops of ~6°C and cooling powers of ~96 watts per square meter (W m–2) under solar intensities of 890 and 750 W m–2, respectively. The performance equals or surpasses those of state-of-the-art PDRC designs, and the techni...
