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...

Using finite-temperature phonon calculations and machine-learning methods, we assess the mechanical stability of about 400 semiconducting oxides and fluorides with cubic perovskite structures at 0, 300, and 1000 K. We find 92 mechanically stable compounds at high temperatures—including 36 not mentioned in the literature so far—for which we calculate the thermal conductivity. We show that the th...

Dental caries is a public health issue that affects people all over the world. Untreated causes progressive tooth destruction, which frequently accompanied by considerable pain, lowering one's quality of life. Fluoride use so as to reduce causation dental has been widespread since long time involves nearly six eight decades. Especially in those who have got specific type involve their smooth su...

Fluorine, the most reactive and electro-negative halogen on the earth, is an element that virtually never occurs naturally in its free, gaseous form In the form of fluorides, however, it is one of the most plentiful and wide spread of elements, standing seventeenth in order of abundance in the earth's crust. Fluorides occur in water, soil, rocks, dusts and the atmosphere. It is also present in ...

Air and moisture stable homoleptic bis(diimidazolylidine)nickel(II) complexes, ([(diNHC)(2)Ni](2+)) 3a,b and their corresponding silver(I) 4a,b and palladium(II) 5a,b complexes were synthesized and characterized by NMR and single crystal X-ray analysis. The catalytic potential of complex 3a was assessed in Mizoroki-Heck and Suzuki-Miyaura coupling reactions. In the Suzuki-Miyaura coupling react...

1. The delayed neurotoxic effects of some organophosphorus compounds are associated with phosphorylation of the active site of a nervous-tissue enzyme capable of hydrolysing phenyl phenylacetate. 2. Neurotoxic organophosphorus compounds and some carbamates and sulphonyl fluorides progressively inhibit the enzyme, attaching a substituent covalently at the active site. 3. Prolonged inhibition of ...

(Hetero)arylsulfur compounds where the S atom is in oxidation state VI represent a large percentage of molecular functionalities present organic chemistry. More specifically, (hetero)aryl-SVI fluorides have recently received enormous attention because their potential as chemical biology probes, result reactivity simple, modular, and efficient manner. Whereas synthesis application level 1 fluori...

This paper reviews the synthesis, structure and applications of metal fluoride nanoparticles, with particular focus on rare earth (RE) doped fluoride nanoparticles obtained by our research group. Nanoparticles were produced by precipitation methods using the ligand ammonium di-n-octadecyldithiophosphate (ADDP) that allows the growth of shells around a core particle while simultaneously avoiding...
