Design and Characterization of Mixed Ligand Mn (II) Complex With 4‐Iodo‐Pyridine‐2‐Carboxylic Acid for Enhanced Nonlinear Optical Applications: A Theoretical and Experimental Approach

Applied Organometallic Chemistry, Volume 39, Issue 7, July 2025.
Mn (II) complex with 4‐iodo‐pyridine‐2‐carboxylic acid and 5,5′‐dimethyl‐2,2′‐bipyridine has shown significant potential for nonlinear optical (NLO) applications, as evidenced by both static and frequency‐dependent NLO analyses. This is attributed to the interaction between Mn (II) ion and the coordinated ligands, which facilitates intramolecular ...

Current‐Mirror Based Filters With Reduced Circuit Complexity

International Journal of Circuit Theory and Applications, Volume 53, Issue 7, Page 3993-3999, July 2025.
A novel current‐mirror‐based lossless integration stage, derived from the corresponding lossy integration stage, just by adding an extra DC current source, is introduced in this letter. The unique contribution that it offers is the reduction of the circuit complexity in the resulting current‐mode systems, where the introduced integrator is utilized.

Simulated Infrared and Raman Spectra of Phosphorus Allotropes

Journal of Raman Spectroscopy, Volume 56, Issue 7, Page 567-576, July 2025.
In this computational work, we have systematically investigated the vibrational properties of white γ, white β, fibrous red, violet and black phosphorus allotropes by simulating their infrared (IR) and Raman spectra by means the density functional theory (DFT) level.

Assessing the Aromaticity of Fluorinated Benzene Derivatives Using New Descriptors Based on the Distributed Multipole Analysis (DMA) Partition of the Electron Density

Journal of Physical Organic Chemistry, Volume 38, Issue 7, July 2025.
The effect of fluorination on the aromaticity of 12 compounds using a new set of descriptors based on the distributed multipole analysis (DMA) partition of the electron density was investigated. The decrease in the aromaticity of the investigated systems, depending on the number and position of the substituents, could be quantified.

Irradiated Coherent States in Magnetoresistance of 2D Electron Systems

physica status solidi (b), Volume 262, Issue 7, July 2025.
A theoretical approach on the microwave‐induced resistance oscillations based on the coherent states of the quantum harmonic oscillator is reported. The coherent state expression for the quantum oscillator under a time‐dependent force is calculated. It is found that the principle of minimum uncertainty of coherent states, involving time and energy, is ...
