Facile in situ fabrication of oriented titania submicrorods embedded into a superelastic nickel-titanium alloy fiber substrate and their application in solid-phase microextraction

03.07.2018 | Feifei Wang; Zhuo Wang; Ziyi Wang; Rong Zhang; Junliang Du; Xin-zhen Du, New Journal of Chemistry, 2018

A nickel-titanium oxide (NiO/TiO2) coating was in situ grown on a nickel-titanium alloy (NiTi) fiber substrate by anodic oxidation. After annealing, a uniform and dense Ni-free coating of rutile phase TiO2 submicrorods (TiO2SRs) was formed. In particular, TiO2SRs were embedded into the NiTi fiber ...


Chemiluminescence of black phosphorus quantum dots induced by hypochlorite and peroxide

03.07.2018 | Houjing Liu; Mingxia Sun; Yingying Su; Dongyan Deng; Jianyu Hu; Yi Lv, Chemical Communication, 2018

For the first time, black phosphorus quantum dots (BP QDs) were found to show chemiluminescence (CL) properties in the presence of hydrogen peroxide (H2O2) and hypochlorite (ClO−). Excited phosphorus oxides (HPO) resulting from the oxidation of BP QDs account for CL emission. Taking triacetone ...


A[small beta] under stress: the effects of acidosis, Cu2+-binding, and oxidation on amyloid [small beta]-peptide dimers

03.07.2018 | Qinghua Liao; Michael C. Owen; Sofia Bali; Bogdan Barz; Birgit Strodel, Chemical Communication, 2018

In light of the high affinity of Cu2+ for Alzheimer's Aβ1–42 and its ability to subsequently catalyze the formation of radicals, we examine the effects of Cu2+ binding, Aβ oxidation, and an acidic environment on the conformational dynamics of the smallest Aβ1–42 oligomer, the Aβ1–42 dimer. ...


First-principles calculations of oxidation potentials of electrolytes in lithium–sulfur batteries and their variations with changes in environment

03.07.2018 | Jaebeom Han; Perla B. Balbuena, Physical Chemistry Chemical Physics, 2018

Oxidation potentials of electrolyte molecules in Li–sulfur (Li/S) batteries and their variations in various solvent environments are investigated using first-principles calculations in order to understand oxidative decomposition reactions of electrolytes for cathode passivation. Electrolyte ...


Electrochemical properties and C-H bond oxidation activity of [Ru(tpy)(pyalk)Cl]+ and [Ru(tpy)(pyalk)(OH)]+

03.07.2018 | Christian K Nilles; Hashini Herath; Hanna Fanous; Angel Ugrinov; Alexander Rene Parent, Dalton Transactions, 2018

[Ru(tpy)(pyalk)Cl]Cl (pyalk = 2-(2’-Pyridyl)-2-propanol) was synthesized and characterized crystallographically and electrochemically. Upon dissolution in water and acetonitrile, [Ru(tpy)(pyalk)Cl]Cl was found to form [Ru(tpy)(pyalk)Cl]+ and [Ru(tpy)(pyalk)(OH)]+, respectively. The Ru(II/III) ...


Redox-induced switch between luminescent and magnetic properties in a trinuclear cyanide-bridged compound

03.07.2018 | Xiao-quan Zhu; Shaodong Su; Yuehong Wen; Lintao Zhang; Yu-YIing Yang; Xintao Wu; Tianlu Sheng, Dalton Transactions, 2018

A trinuclear cyanide-bridged luminescent compound trans-RuII(DMAP)4(CN)2[(PY5Me2)Mn]2[PF6]4 (1-R) and its oxidation product, ferromagnetic trans-RuIII(DMAP)4(CN)2[(PY5Me2)Mn]2-[PF6]5 (1-O) have been synthesized and fully characterized. This is the first example of molecular materials about ...


Copper-catalyzed oxidative cross-dehydrogenative coupling of 2H-chromenes and terminal alkynes

03.07.2018 | Fei Yang; Yangshan Li; Paul E. Floreancig; Xiaoyan Li; Lei Liu, Organic & Biomolecular Chemistry, 2018

An efficient copper-catalyzed cross-dehydrogenative coupling of 2H-chromenes and terminal alkynes mediated by DDQ has been established. A protic additive, EtOH, proved to be crucial for harmonizing the oxidation with a subsequent alkynylation step by retaining the oxidation state of an ...


Carbenium ion formation by fragmentation of electrochemically generated oxonium ions

03.07.2018 | Anna Lielpetere; Aigars Jirgensons, Organic & Biomolecular Chemistry, 2018

Fragmentation of electrochemically generated oxonium ions can be exploited to form carbenium ions at low oxidation potential in the presence of a nuclephile. The application of this concept is demonstrated for allylation of carbenium ions generated by anodic oxidation of ...


Synthesis of efficient Co and N co-doped carbon catalysts with high surface areas for selective oxidation of ethylbenzene

03.07.2018 | Yuan Li; Shanshan Jie; Kun Li; Zhigang Liu, New Journal of Chemistry, 2018

In this manuscript, Co and N co-doped carbon catalysts with high surface areas were prepared via the pyrolysis of cobalt nitrate and 1,10-phenanthroline monohydrate, using Mg(OH)2 as a pore former, followed by acid etching. Techniques such as BET analysis, TEM, HRTEM, XPS, and Raman and XRD ...


Nickel nanowires-based composite material applied to the highly enhanced non-enzymatic electro-oxidation of ethanol

01.07.2018 | Author(s): Cecilia S. Tettamanti, María L. Ramírez, Fabiana A. Gutierrez, Paula G. Bercoff, Gustavo A. Riv ..., Microchemical Journal, 2018

Publication date: November 2018 Source:Microchemical Journal, Volume 142 Author(s): Cecilia S. Tettamanti, María L. Ramírez, Fabiana A. Gutierrez, Paula G. Bercoff, Gustavo A. Rivas, Marcela C. Rodríguez In this work, we report the building of a nanostructured platform with ...
