The family of crystals known as Tutton's salts plays a significant role in physics and chemistry; because they are used phase transition studies to define models applied materials. importance material engineering is recent, applications adiabatic degaussing refrigerators solid-state anodes. Studies the (NH4)2Ni(SO4)2∙6H2O (NH4)2Co(SO4)2·6H2O widely found literature but do not occur for mixture ...

We have shown that urea-extracted cell wall of entomopathogenic Bacillus sphaericus 2297 and some other strains is a potent larvicide against Culex pipiens mosquitoes, with 50% lethal concentrations comparable to that of the well-known B. sphaericus binary toxin, with which it acts synergistically. The wall toxicity develops in B. sphaericus 2297 cultures during the late logarithmic stage, earl...

The peculiarities of K2Gd(PO4)(MoO4) single crystal growth from combined phosphate-molybdate melts have been investigated. formation regions GdPO4, KGd(MoO4)2 and their cocrystallization fields with the mixed anionic compound potassium – gadolinium established. IR spect­roscopy showed that in all compounds molybdenum phosphorus are a tetrahedral environment, phase composition was confirmed by X...

The L-alanine family crystals such as pure L-Alanine, hydrochloride (HCl) mixed Lalanine, potassiumchloride (kcl) mixed l-alanine and potassium dihydrogen phosphate (kdp) mixed l-alanine have been successfully grown from the aqueous solution by slow evaporation method at room temperature. The grown crystals FT-IR spectral studies were recorded for each sample and the molecular vibrational frequ...

conclusions: it can be concluded that most of a. baumannii isolates can form biofilm in microtiter plate and tube. the results also verified that most of these isolates were resistant to ciprofloxacin and imipenem. results: results showed that in tube method under shaking, 22% of clinical isolates were strong biofilm producers while 23% of them were not able to form biofilms. in this experiment...

We report on the experimental observation of speckle formation from a transparent crystal formed by a random distribution of nonlinear domains. The angular distribution of second-harmonic light generated by a transparent strontium barium niobate crystal is measured for different diameters of the fundamental beam and crystal thicknesses. Distinct manifestations of speckle pattern formation are f...
