In the current paper, we report the synthesis of three-dimensional (3D) copper sulfide (CuS) with novel tertiary hierarchical architectures prepared by a one-step solvothermal method through the reaction of sulfur powder and solid copper for the first time. In this work, porous copper foam is ...
23-May-2012 | George L Donati; Renata S Amais; Joaquim A Nobrega, Journal of Analytical Atomic Spectrometry, 2012
Phosphorus and S are challenging elements in inductively coupled plasma quadrupole mass spectrometry (ICP-QMS). Their high ionization energies and severe spectral interferences from polyatomic species abundant in the plasma can compromise sensitivity and accuracy in ICP-QMS determinations. An ...
23-May-2012 | Yaoshun Wen; Gang Wang; Chunming Xu; Jinsen Gao, Energy & Fuels, 2012
On the basis of the cracking desulfurization of naphtha and the subsidiary riser in the fluid catalytic cracking (FCC) process for gasoline reformation, the in situ sulfur removing from naphtha in the FCC unit was investigated and a conceptual process was proposed. The relevant experiments were ...

We show that in contrast to conventional compound photocatalysts, α-sulfur crystals of cyclooctasulfur (S8) are a visible-light-active elemental photocatalyst. The α-S crystals were found to have the ability not only to generate ·OH radicals but also to split water in a photoelectrochemical ...

Caerulomycins (CAEs) and collismycins (COLs), which mainly differ in sulfur decoration, are two groups of structurally similar natural products containing a 2,2′-bipyridine (2,2′-BP) core, derivatives of which have been widely used in chemistry. The biosynthetic pathways of CAEs and COLs remain ...
23-May-2012 | Kyle L. Kimmel; Jimmie D. Weaver; Melissa Lee; Jonathan A. Ellman, Journal of the American Chemical Society, 2012
The highly enantioselective protonation of nitronates formed upon the addition of α-substituted Meldrum’s acids to terminally unsubstituted nitroalkenes is described. This work represents the first enantioselective catalytic addition of any type of nucleophile to this class of nitroalkenes. ...
22-May-2012 | Myung-Joon Jeong, Anne-Laurence Dupont, E. René de la Rie, Cellulose, 2012
The degradation of cellulose in paper due to the formation of a tideline at the wet-dry interface when paper is suspended in water was explored. SEC/MALS was used to assess the molar mass, while ICP/MS, SEM/EDS and CE/UV provided a qualitative and quantitative analysis of the elements and ...
22-May-2012 | Shen, Yuesong; Li, Peiwen; Xu, Xinhai; Liu, Hong, ChemInform, 2012
Abstract Review: 104 refs.

Abstract (E,E)‐2,6‐Bis(chloromethylidene)‐1,4‐dithiane (II) is regio‐ and stereoselectively obtained in an anti‐Markovnikov addition at both triple bonds of compound (I).
22-May-2012 | Niu, Hong‐Ying; Xia, Chao; Qu, Gui‐Rong; Wu, Shan; Jiang, Yi; Jin, Xin; Guo, Hai‐Ming, ChemInform, 2012
Abstract A rapid and operationally simple method for the synthesis of various C‐6 alkylthiosubstituted purine nucleosides is developed which acts under microwave irradiation and without any metal catalyst.
