The 2,8-dioxa-5-aza-1-sila-bicyclo[3.3.01.5]octane PhN(CH2CH2O)2SiH2 as reducing reagent: synthesis and molecular structure of PhN(CH2CH2O)2Sn

Main Group Metal Chemistry, 2013
The synthesis of the 2,8-dioxa-5-aza-1-stanna-bicyclo[3.3.01.5]octane [PhN(CH2CH2O)2Sn]n (3) by a combined ligand exchange/redox reaction and independently by the reaction of tin(II)butoxide with N-phenyldiethanolamine is reported.

Electronic Tuning of Mixed Quinoidal‐Aromatic Conjugated Polyelectrolytes: Direct Ionic Substitution on Polymer Main‐Chains [PDF]

, 2019
The synthesis of conjugated polymers with ionic substituents directly bound to their main chain repeat units is a strategy for generating strongly electron-accepting conjugated polyelectrolytes, as demonstrated through the synthesis of a series of ionic ...

Developmental Disorders in Children Recently Diagnosed With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Neurocognitive deficits in adult survivors of childhood cancer are well established, but less is known about developmental disorders (DD) arising shortly after cancer diagnosis. Using 2016–2019 linked Ohio cancer registry and Medicaid data, we compared DD among 324 children with cancer and 606,913 cancer‐free controls.

Spin and exchange coupling for Ti embedded in a surface dipolar network [PDF]

, 2011
We have studied the spin and exchange coupling of Ti atoms on a Cu$_2$N/Cu(100) surface using density functional theory. We find that individual Ti have a spin of 1.0 (i.e., 2 Bohr Magneton) on the Cu$_2$N/Cu(100) surface instead of spin-1/2 as found by ...

Approximation Algorithm for N-distance Minimal Vertex Cover Problem

, 2016
Evolution of large scale networks demand for efficient way of communication in the networks. One way to propagate information in the network is to find vertex cover. In this paper we describe a variant of vertex cover problem naming it N-distance Vertex Minimal Cover(N-MVC) Problem to optimize information propagation throughout the network.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Tetrakis(5,7-dimethylquinolin-8-olato-κ2N,O)hafnium(IV) dimethylformamide disolvate

Acta Crystallographica Section E, 2011
In the title compound, [Hf(C11H10NO)4]·2C3H7NO, the HfIV atom is coordinated by four N,O-donating bidentate 5,7-dimethyl-8-quinolinolate (Ox−) ligands arranged to give a distorted square-antiprismatic coordination polyhedron.
