Objectives: This study aimed to assess the effect of three commonly consumed beverages on surface roughness of polished and glazed zirconia-reinforced lithium silicate (ZLS) glass ceramics.Materials and Methods: In this experimental study, 104 rectangular... see more

Background. Stroke is among the leading causes of death and disability worldwide with rising incidence among young people today. This is the third most common cause of disability-adjusted life-years worldwideObjective. The present study evaluated the cere... see more

In contrast to alkyl compounds of lithium, which play an important role in organometallic chemistry, the corresponding heavier alkali metal compounds are less investigated. These compounds are mostly insoluble in inert solvents or undergo solvolysis in co... see more

Lithium titanates are used in various applications, such as anode materials for lithium intercalation (Li4Ti5O12) or breeding materials in fusion reactors (Li2TiO3). Here, we report the formation of nano-crystalline lithium titanates by a mechanochemical ... see more

We describe a series of metastable Li2O2 crystal structures involving different orientations and displacements of the O22- peroxy ions based on the known Li2O2 crystal structure. Within the vicinity of the chemical potential ?G ~ 0.20 eV/Li from the therm... see more

In this review article were considered the works of electrochemical sensors modified with molybdenum oxide. The work of sensors based on molybdenum oxide was systematized, a comparison table was developed, the sensors were classified according to the purp... see more

New fused derivatives – 2-(arylsulfanylmethyl)-2,3,5,6-tetrahydroimidazo[2,1-b][1,3]thiazol-7-onium perchlorates have been synthesized by the cyclosulfenylation reaction of 3-allylthiohydantoin in highly polar nitromethane in the presence of an equimolar ... see more

The role of the electrophilic intramolecular cyclization (EIC) reaction of unsaturated carboxylic acid amides has been described for the design of arylthio-containing lactams and lactones. In order to identify the effect of the styryl moiety on ... see more

The reaction between methyl 2-methoxyphenylacetate and 4-methoxy-2-O-methoxymethylbenzaldehyde to form the aldol product methyl 3-hydroxy-2-(2”-methoxyphenyl)-3-(2’-O-methoxymethyl-4’-methoxyphenyl)propanoate is significant in the current study of the syn... see more
