Synthesis and Properties of Cross‐Shaped Donor–Acceptor Dyes: Tunable Emission From Visible to Near‐Infrared in Solution and Solid‐State

European Journal of Organic Chemistry, Volume 29, Issue 27, 17 July 2026.
A comprehensive investigation (synthesis, electrochemistry, photophysics, and theory) of seven new cross‐shaped dyes based on N,N,N’,N’‐tetraphenyl‐1,4‐phenylenediamine cores substituted with different electron‐withdrawing groups, reveals tunable emission properties spanning the visible to near‐infrared range, both in solution and in the solid state ...

Stability Analysis and Design of Negative Impedance Converters: application to circuit and small antennas [PDF]

Radioengineering, 2016
Negative impedance converters (NICs) have been proposed as structures to improve the performance of RF circuits and electrically small antennas. However, NICs suffer from stability problems.

A novel non-invasive embryo evaluation method (NICS-Timelapse) with enhanced predictive precision and clinical impact

Heliyon
The selection of the finest possible embryo in in-vitro fertilization (IVF) was crucial and revolutionary, particularly when just one embryo is transplanted to lessen the possibility of multiple pregnancies.

py.Aroma: An Intuitive Graphical User Interface for Diverse Aromaticity Analyses

Chemistry
The nucleus-independent chemical shift (NICS) criterion plays a significant role in evaluating (anti-)aromaticity. While being readily accessible even for non-computational chemists, adding ghost atoms for multi-points NICS evaluations poses a ...
