5-(Trifluoromethoxy)isatin

Acta Crystallographica Section E, 2012
The title compound [systematic name: 5-(trifluoromethoxy)-1H-indole-2,3-dione], C9H4F3NO3, crystallized with two molecules in the asymmetric unit. Intermolecular N—H...O hydrogen bonds link the molecules to form layers parallel to the ab plane.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Crossing Minimization for 1-page and 2-page Drawings of Graphs with Bounded Treewidth

Journal of Graph Algorithms and Applications, 2018
We investigate crossing minimization for $1$-page and $2$-page book drawings. We show that computing the $1$-page crossing number is fixed-parameter tractable with respect to the number of crossings, that testing $2$-page planarity is fixed-parameter ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Toward a Theoretical Understanding of the Corrosion Inhibitive Performance on Iron Surface by Some Macrocyclic Polyether Compounds Containing 1, 3, 4-thiadiazole Entity

International Journal of Electrochemical Science, 2018
The corrosion inhibitive performance, in acidic medium, of macrocyclic polyether compounds: 1-MCTH, 2-MCTH and their protonated forms, was studied on the basis of their degree of planarity, global and local electronic proprieties as well as their ...

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

5,6-Dibromo-1H-indole-2,3-dione

IUCrData, 2017
The title compound, C8H3Br2NO2, crystallizes with two near planar molecules in the asymmetric unit, with non-H atoms possessing mean deviations from planarity of 0.012 and 0.014 Å. The two molecules are connected by an N—H...O and a C—H...O hydrogen bond.
