the angular dependent magnetoresistance oscillation (admro) of the stage-2 ibr graphiteintercalation compound (gic) was studied between 1.8 k and 110 k in magnetic fields between 1 and 9t. there was a series of peaks in the c-axis resistance as the field direction was changed from the c axisto the (001) plane. the field independence of the angular positions of the peaks, showing that theoscilla...
TCNQ is a fascinating molecule with potential for optical, electronic and magnetic materials. Our work studies the low energy lattice modes of parent compound to further understand vibrational properties including their temperature dependence.
Boron/carbon/nitrogen (B/C/N) materials and boron/carbon (B/C) having graphite-like layered structures were synthesized by using a chemical vapor deposition (CVD) method. Calcium (Ca) was intercalated into the B/C reaction of Ca with host film to form an intercalation compound second stage structure as main product. also co-intercalated lithium (Li) B/C/N liquid-alloy method compound. These are...
learning english is very popular all over the world nowadays and it is considered a high prestigious language among citizens of different societies. one of the most important materials for learning a new language are textbooks. the debate that whether learning a new language is natural and neutral or ideological and influential on people’s worldviews, has always been of great importance.
Recent advances in theoretical structure prediction methods and high-throughput computational techniques are revolutionizing experimental discovery of the thermodynamically stable inorganic materials. Metastable materials represent a new frontier for these studies, since even simple binary non-ground state compounds of common elements may be awaiting discovery. However, there are significant re...
The ability to computationally predict the properties of new materials, even prior to their synthesis, has been made possible due to the current accuracy of modern ab initio techniques. In some cases, high-throughput computations can be used to create large data sets of potential compounds and their computed properties. However, regardless of the field of application, such a computational high-...
objectives: securinega virosa roxb (ex willd) baill (euphorbaiceae) root bark has been reportedly used in african traditional medicine in the management of mental illnesses. previously, the sleep-inducing potential of the crude methanol root bark of securinega virosa extract and its butanol fraction have been reported. the study aimed to isolate and characterize the bioactive constituent that m...
background and objectives: due to the importance of finding of new antibacterial agents, the antibacterial properties of prosopis cineraria aerial parts were investigated using a bioassay guided fractionation scheme. materials and methods: the organic extract was prepared via maceration in methanol, followed by the fractionation using n-hexane and ethyl acetate. the mics of fractions were deter...
background pain experience makes a serious anxiety for both patient and clinician before and after root canal treatment. pain is a complex psychophysiologic phenomenon. objectives the aim of this randomized control trial study was to evaluate the analgesic effect of odontopaste® and a corticosteroid containing compound medicament between root canal therapy appointments. materials and methods on...
synthesis and characterization of 6-(hydroxymethyl)-14, 16-dimethyl-13, 14, 16, 17-tetrahydro-6h-13, 17-epiminodibenzo [e, l] [1, 4] dioxacyclotridecin-15 (7h)-oneabstractnew 6-(hydroxymethyl)-14, 16-dimethyl-13, 14, 16, 17-tetrahydro-6h-13, 17-epiminodibenzo [e, l] [1, 4] dioxacyclotridecin-15 (7h)-one (2a) was synthesized in good yield by the petrenko–kritchenko reaction of 2, 2'-((3-hydroxyp...
