We report a detailed study of electrical and thermal transport properties in 2H-M$_x$TaS$_2$ (M = Mn, Co) magnets where M atoms are intercalated the van der Waals gap. The intercalation induces ferromagentism with an easy-plane anisotropy 2H-Mn$_x$TaS$_2$, but ferromagnetism strong uniaxial 2H-Co$_{0.22}$TaS$_2$, which finally evolves into three-dimensional antiferromagnetism 2H-Co$_{0.34}$TaS$...

The purpose of the present article is to show the multilinearity for symbols in Goodwillie-Lichtenbaum motivic complex in two cases. The first case shown is where the degree is equal to the weight. In this case, the motivic cohomology groups of a field are isomorphic to the Milnor’s K-groups as shown by Nesterenko-Suslin, Totaro and Suslin-Voevodsky for various motivic complexes, but we give an...

Bone exhibits positive form birefringence dominated by and dependent upon the orientation of its collagen. The biomechanical efficacy of bone as a tissue is largely determined by collagen fibers of preferred orientation and distribution (and corresponding orientation of mineral crystallites), and evidence is accumulating to demonstrate that this efficacy extends to function at the organ level. ...

This study used density functional theory and the quantum transport method to investigate interfacial coupling spin of transition metals (TMs) with a Fe, Co, Ni/2H-VSe2 hybrid nanostructure. Because indirect TM-Se-V led an obvious reduction magnetic moment disappearance half-metal characteristics 2H-VSe2, expected spin-filtering effect individual TMs 2H-VSe2 deteriorated at contact region. Neve...

A ruthenium-catalyzed intermolecular [3 + 2] cycloaddition of 2H-azirines and activated alkynes is reported, which provides polysubstituted pyrroles in moderate to good yields. This approach features a C-N bond cleavage of 2H-azirines by a ruthenium catalyst. The results of this study would provide a complementary method to synthesize polysubstituted pyrroles from the known 2H-azirine approache...

(a) Define a linear mapping R2h h : R 5 → R3 according to the full weighting scheme (see Lecture slides). Setup the respective matrix R2h h . (b) Define a linear mapping Ph 2h : R 3 → R5 which prolongates a solution vector from the coarse to the fine grid using linear interpolation (see Lecture slides). Setup the respective matrix Ph 2h. (c) Based on the matrices R2h h , P h 2h and Ah, compute ...

A two-step sequence for the synthesis of various 3,4-dihydro-2H-1,3-thiazines is presented. In the first step, 2H-1,3-thiazines were prepared by a new multicomponent reaction (MCR). Starting from β-chlorovinyl aldehydes, this MCR offers an efficient and facile access to 2,2-dialkyl- and 2-alkyl-2-aralkyl-5,6-diaryl-2H-1,3-thiazines. The potential of these products in subsequent reactions was ve...

New coumarin derivatives, namely 7-[(5-amino-1,3,4-thiadiazol-2-yl)methoxy]-2H-chromen-2-one, 5-[(2-oxo-2H-chromen-7-yloxy)methyl]-1,3,4-thiadiazol-2(3H)-one, 2-[2-(2-oxo-2H-chromen-7-yloxy)acetyl]-N-phenylhydrazinecarbothioamide, 7-[(5-(phenylamino)-1,3,4-thiadiazol-2-yl)methoxy]-2H-chromen-2-one and 7-[(5-mercapto-4-phenyl-4H-1,2,4-triazol-3-yl)methoxy]-2H-chromen-2-one were prepared starting...

Deuterium-labeled nicotinamide cofactors such as [4-2H]-NADH can be used mechanistic probes in biological redox processes and offer a route to the synthesis of selectively [2H] labeled chemicals via biocatalytic reductive deuteration. Atom-efficient routes formation recycling are therefore highly desirable but require careful design order alleviate requirement for [2H]-labeled reducing agents. ...
