Graphene-wrapped FeF3 nanocrystals (FeF3/G) have been successfully fabricated for the first time by a vapour-solid method, which can be generalized to synthesize other metal fluorides. The as-synthesized FeF3/G delivers a charge capacity of 155, 113, and 73 mA h g(-1) at 104, 502, and 1040 mA g(-1) in turn, displaying superior rate capability to bare FeF3. Moreover, it exhibits stable cyclabili...

In recent years, Lanthanide (Ln3+)-doped nanocrystals have become promising alternatives to organic fluorophore because Ln3+ ions can exhibit unique luminescent properties, such as large anti-Stokes shifts, low auto fluorescence background, low toxicity and high penetration depth [1]. In terms of the mechanism of luminescence, luminescence of Ln3+ ions can be divided into down-conversion and up...

AIM The aim of our study was to chronologically analyse various public health measures of fluoride use in caries prevention. METHODS We systematically searched the PubMed database on the preventive role of fluorides in public health, published from 1984 to 2014. The search process was divided into four steps, where inclusion and exclusion criteria were defined. Qualitative methodology was use...

The use of fluorides in dental public health programs has a long history. With the availability of fluoridation and other forms of fluorides, dental caries have declined dramatically in the United States. This article reviews some of the ways fluorides are used in public health programs and discusses issues related to their effectiveness, cost, and policy.

This communication describes a facile and mild chemical etching method for resizing of CdTe nanocrystals, which provides a possible approach for tailoring the size-dependent properties of the nanocrystals.

ZnO and ZnO: Mn nanocrystals were synthesized via reverse micelle method. The structural properties of nanocrystals were investigated by XRD. The XRD results indicated that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. Resistive gas sensors were fabricated by providing ohmic contacts on the tablet obtained from compressed nanocrystals powder and the installation ...

Effects of 5 kinds of fluorides on the twitch of the sartorius muscle of the bull frog were investigated. All of the fluorides (0.1-2.0 mM) enhanced the twitch evoked by nerve stimulation. The extents of enhancement at 2.0 mM were in the order: stannous fluoride much greater than potassium fluoride greater than sodium silico fluoride greater than sodium fluoride greater than diammine silver flu...

the aim of this study was to investigate the barrier properties of cellulose nanocrystals-pvananocomposites. nanocomposite films with different filler loading levels (3, 6, 9 and 12% by wt) weredeveloped by solvent casting method. the effect of cellulose nanocrystals on the barrier properties ofthe nanocomposites was studied. to this end, moisture absorption, water vapor permeability (wvp),oxyg...
