Crystal structure of methyl (E)-2-(1-methyl-2-oxoindolin-3-ylidene)acetate

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2015
The title compound, C12H11NO3, is essentially planar, with the mean plane of the acetate side chain [–C—C(=O)—O—C] being inclined to the mean plane of the indole ring system by 12.49 (7)°.

A Novel Digitalization Approach for Smart Materials – Ontology‐Based Access to Data and Models

open access: yesAdvanced Engineering Materials, Volume 27, Issue 8, April 2025.
In order to access heterogeneous material data and model‐based knowledge, the established ontology‐based data access (OBDA) is extended to include material models. This novel ontology‐based data and model access (OBDMA) enables the computation of new responses beyond stored data.

Supramolecular Assembly of Ag(I) Centers: Diverse Topologies Directed by Anionic Interactions. [PDF]

open access: yes, 2014
Ag(I)-Ag(I) interactions in supramolecular structures have been achieved through the use of structural support from the ligand frames. In structures involving simple ligands like pyridine, strong π-π interaction leads to spatial ordering of the ...

(3Z)-3-Benzylidene-1H-benzimidazo[1,2-a]imidazol-2(3H)-one

open access: yesIUCrData, 2016
In the title compound, C16H11N3O, the molecular conformation is partially determined by an intramolecular C—H...π(ring) interaction. In the crystal, pairwise N—H...N hydrogen bonds form dimers, which associate into stacks through a combination of C—H...O,

Numerical Studies of Influencing Factors on the Homogeneity of the Powder Mixture during the Powder Spreading Process of Powder Bed Fusion–Laser Beam/Metal

open access: yesAdvanced Engineering Materials, EarlyView.
AISI 304L stainless steel powder is mixed with silicon nitride (Si3N4) powder and processed by PBF‐LB/M, allowing partial retention of Si3N4. The numerical approach effectively predicts the Si3N4 powder homogeneity and N content distribution on the powder bed. Recent studies have focused on the alloying of nitrogen (N) in high‐alloy stainless steels by

Cofacially Arrayed Polyfluorenes: Spontaneous Formation of π-Stacked Assemblies in the Gas Phase [PDF]

open access: yes, 2017
Understanding geometrical and size dependencies of through-space charge delocalization in multichromophoric systems is critical to model electron transfer and transport in materials and biomolecules.

Soliton interaction in a fiber ring laser [PDF]

open access: yesarXiv, 2009
We have experimentally investigated the soliton interaction in a passively mode-locked fiber ring laser and revealed the existence of three types of strong soliton interaction: a global type of soliton interaction caused by the existence of unstable CW components; a local type of soliton interaction mediated through the radiative dispersive waves; and ...
