Organic letters

Yang X, Cao ZH, Zhou Y, Cheng F, Lin ZW, Ou Z, Yuan Y, Huang YY.
PMID: 29652153
Org Lett. 2018 May 04;20(9):2585-2589. doi: 10.1021/acs.orglett.8b00721. Epub 2018 Apr 13.

A three-component Petasis-type gem-difluoroallylation reaction of using pinacol gem-difluoroallylboronates, aldehydes or isatin, and β-amino alcohols enabled by the neighboring hydroxyl group in amine is reported, affording various racemic and chiral gem-difluorohomoallylamine derivatives with good to excellent results. Based on...

Chemical and Bandgap Engineering in Monolayer Hexagonal Boron Nitride.

Scientific reports

Ba K, Jiang W, Cheng J, Bao J, Xuan N, Sun Y, Liu B, Xie A, Wu S, Sun Z.
PMID: 28367992
Sci Rep. 2017 Apr 03;7:45584. doi: 10.1038/srep45584.

Monolayer hexagonal boron nitride (h-BN) possesses a wide bandgap of ~6 eV. Trimming down the bandgap is technically attractive, yet poses remarkable challenges in chemistry. One strategy is to topological reform the h-BN's hexagonal structure, which involves defects or...

Medical image computing and computer-assisted intervention : MICCAI ... International Conference on Medical Image Computing and Computer-Assisted Intervention

Chen GH, Shah D, Golland P.
PMID: 26889499
Med Image Comput Comput Assist Interv. 2015 Oct;9351:140-148. doi: 10.1007/978-3-319-24574-4_17. Epub 2015 Nov 18.

Despite the popularity and empirical success of patch-based nearest-neighbor and weighted majority voting approaches to medical image segmentation, there has been no theoretical development on when, why, and how well these nonparametric methods work. We bridge this gap by...

ACS Nano. 2016 Sep 27;10(9):8289-98. doi: 10.1021/acsnano.6b02315. Epub 2016 Aug 17.

A reversible cathode material in an ether-based electrolyte for high-energy lithium batteries was successfully fabricated by homogeneously confining heteroatomic SenS8-n molecules into nitrogen-doped mesoporous carbons (NMCs) via a facile melt-impregnation route. The resultant SenS8-n/NMC composites exhibit highly reversible electrochemical...
