Hyperbolic octonionic Proca-Maxwell equations
(Verlag Z Naturforsch, 2008)
In this study, after introducing the hyperbolic octonionic (counteroctonion) algebra, which is also expressed in the sub-algebra of sedenions, and differential operator, Proca-Maxwell equations and relevant field equations ...
Synthesis, characterization, electrochemistry and VOC sensing properties of novel ball-type dinuclear metallophthalocyanines
(Elsevier Science Sa, 2014)
New homodinuclear ball-type Cu(II)-Cu(II) 4, Zn(II)-Zn(II) 5, and Co(II)-Co(II) 6 phthalocyanines were synthesized from 4,4'-(9H-fluorene-9-yl-dimethoxy)diphthalonitrile 3, which was obtained by the reaction of ...
Benzotriazole-mediated amidoalkylations of nitroalkanes, nitriles, alkynes and esters
(Arkat Usa Inc, 2007)
Reactions of readily available and stable N-(alpha-amidoalkyl)benzotriazoles 1 ( derived from a variety of aliphatic, aromatic or heterocyclic aldehydes) with diverse nitroalkanes, nitriles, alkynes and esters afforded ...
A naturally occuring triterpene saponin ardisiacrispin B displayed cytotoxic effects in multi-factorial drug resistant cancer cells via ferroptotic and apoptotic cell death
(Elsevier GMBH, Urban & Fischer Verlag, 2018)
Introduction: Multidrug resistance of cancer cells constitutes a serious problem in chemotherapy and a challenging issue in the discovery of new cytotoxic drugs. Many saponins are known to display anti-cancer effects. In ...
Atomic Layer Deposition of Ultrathin Nickel Sulfide Films and Preliminary Assessment of Their Performance as Hydrogen Evolution Catalysts
(American Chemical Society, 2016)
Transition metal sulfides show great promise for applications ranging from catalysis to electrocatalysis to photovoltaics due to their high stability and conductivity. Nickel sulfide, particularly known for its ability to ...
Oxidation of 2,3,6-trimethylphenol with potassium peroxymonosulfate catalyzed by iron and cobalt phthalocyanine tetrasulfonates in a methanol-water mixture
(Elsevier Science BV, 2008)
Oxidation of 2,3,6-trimethylphenol (TMP) with potassium peroxymonosulfate (KHSO5) catalyzed by iron phthalocyanine tetrasulfonate ([FePcTS]) in an 8-to-1 methanol-water mixture resulted in 43.2-100.0% conversion of TMP and ...
Facile, efficient, and environmentally friendly alpha- and aromatic regioselective chlorination of toluene using KHSO5 and KCl under catalyst-free conditions
(Royal Soc Chemistry, 2015)
Toluene was subjected to room-temperature chlorination with the KHSO5-KCl system in organic solvent-water mixtures. In a typical reaction, the amounts of toluene, KHSO5, and KCl were 1.0, 5.0 and 7.5 millimoles, respectively. ...
Voltammetric and amperometric determination of metoclopramide on boron-doped diamond film electrode
(Versita, 2012)
New methods for the determination of metoclopramide, antiemetic and gastroprokinetic pharmaceutical, were developed, using differential pulse voltammetry (DPV) and flow injection analysis (FIA) with amperometric detection ...
Determination of the LO phonon energy by using electronic and optical methods in AlGaN/GaN
(De Gruyter Open LTD, 2012)
The longitudinal optical (LO) phonon energy in AlGaN/GaN heterostructures is determined from temperature-dependent Hall effect measurements and also from Infrared (IR) spectroscopy and Raman spectroscopy. The Hall effect ...
