In the title compound, C(16)H(14)Br(2)S(2) [systematic name: 1(2),5(2)-dibromo-2,7-dithia-1,5(1,4)-dibenzenaocta-phane], the cen-troids of the two benzene rings are separated by 3.313 (5) Å. The crystal packing exhibits weak inter-molecular S⋯S contacts of 3.538 (2) Å.

Separation and structural characterization of lignin are essential for valueadded utilization of hemicelluloses and lignin in the prehydrolysis liquor (PHL) of a kraft-based Whangee (a genus of bamboo) dissolving pulp production. In this work, lignin in the PHL was separated by acidification treatment (AT) and rotary vacuum evaporation treatment (RVET), and the separated crude lignin was then c...

Introduction Let S be a Noetherian separated scheme of finite dimension, and let SH(S) denote the motivic stable homotopy category of Morel and Voevodsky. In order to get a motivic version of the Postnikov tower, Voevodsky [23] constructs a filtered family of triangulated subcategories of SH(S):

Let X be an Artin stack (always assumed to have quasi-compact and separated diagonal over SpecZ; cf. [2, §1.3]). A coarse moduli space for X is a map π : X → X to an algebraic space such that (i) π is initial among maps from X to algebraic spaces (note that the category of maps from X to an algebraic space is discrete), and (ii) for every algebraically closed field k the map [X (k)]→ X(k) is bi...

The analysis of drop formation and the transition between separated non-separated oil–water flows enables us to better regulate flow parameters pipe inclination angle, which is great significance for improving efficiency oil transportation. Previous studies mainly carried out qualitative through experiments studied flows, very few are conducted on dual continuous or intermittent flow. In additi...
