Isomorphism: `molecular similarity to crystal structure similarity' in multicomponent forms of analgesic drugs tolfenamic and mefenamic acid

open access: yesIUCrJ, 2020
The non-steroidal anti-inflammatory drugs mefenamic acid (MFA) and tolfenamic acid (TFA) have a close resemblance in their molecular scaffold, whereby a methyl group in MFA is substituted by a chloro group in TFA.

Twisted 1‐ and 2‐Azaperopyrenes: Synthesis, Structure, and Properties

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT A synthesis of hitherto unknown 1‐ and 2‐azaperopyrenes, twisted nitrogen‐doped peropyrenes, is reported. The synthesis is based on a Brønsted acid‐mediated benzannulation of alkynes. Key alkyne intermediates are synthesized via two complementary routes, including a Pd/C‐catalyzed, copper‐ and amine‐free Sonogashira‐type coupling of (hetero ...

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Does Institutional Ownership Structure Reduce Greenhouse Gas Emissions? An In‐Depth Study of Corporations Social Responsibility of European‐Listed Firms

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Motivated by the growing attention and concerns surrounding climate change and the potential role of institutional investors' ownership concentration (OC) in reducing corporations' greenhouse gas (GHG) emissions, this article explores the relationship between various forms of institutional ownership and firms' GHG emission intensity. To do so,

A Note On The Series Space |N ̅_p^θ |(μ)

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019
The series space$\left\vert \bar{N}_{p}^{\theta }\right\vert\left( \mu \right) $has recently been introduced and studied by Gökçe and Sarıgöl [1]. Themain purpose of this paper is to determine the $\alpha-$,$\beta-$and$\gamma$_duals of the space and to ...
