Introduction: The elderly population is increasing around the world, and the prevalence of dementia increases with age. Hence, it is expected that the number of people with dementia will increase significantly in the coming ...
Impacts of twenty years of experimental warming on soil carbon, nitrogen, moisture and soil mites across alpine/subarctic tundra communities
(
Nature Publishing Group
, 2017 , Article)
High-altitude and alpine areas are predicted to experience rapid and substantial increases in future temperature, which may have serious impacts on soil carbon, nutrient and soil fauna. Here we report the impact of 20 years ...
Iron and cobalt salicylaldimine complexes as catalysts for epoxide and carbon dioxide coupling: effects of substituents on catalytic activity
(

, 2017 , Article)
The synthesis and characterization of substituted ONNO-donor salen-type Schiff base complexes of general formula [MIII(L)Cl] (L�=�Schiff base ligand, M�=�Fe, Co) is reported. The complexes have been applied as catalysts ...
A Cross-Coupling Approach to Amide Bond Formation from Esters
(
American Chemical Society
, 2017 , Article)
A palladium-catalyzed cross-coupling between aryl esters and anilines is reported, enabling access to diverse amides. The reaction takes place via activation of the C-O bond by oxidative addition with a Pd-NHC complex, ...
Majorana fermions in a box
(
American Physical Society
, 2017 , Article)
Motivated by potential applications to ultracold matter, we perform a theoretical study of Majorana fermions confined to a finite volume, whose boundary conditions are characterized by self-adjoint extension parameters. ...

(
Springer New York LLC
, 2017 , Article)
Poly(aniline-co-3-bromoaniline) copolymers with varying compositions of the monomers have been prepared in this work by copolymerization of aniline and 3-bromoaniline using ammonium persulphate as oxidant. Structure and ...
The theta-complete graph Ramsey number R(θn K5) = 4n - 3 for n = 6 and n≥ 10
(
Charles Babbage Research Centre
, 2017 , Article)
For any two graphs F1 and F2, the graph Ramsey number r(F1, F2) is the smallest positive integer N with the property that every graph of at least N vertices contains F1 or its complement contains F2 as a subgraph. In this ...
