Anharmonic DFT Study of Near-Infrared Spectra of Caffeine: Vibrational Analysis of the Second Overtones and Ternary Combinations

Molecules, 2021
Anharmonic quantum chemical calculations were employed to simulate and interpret a near-infrared (NIR) spectrum of caffeine. First and second overtones, as well as binary and ternary combination bands, were obtained, accurately reproducing the lineshape ...

Electrophilic Functionalization of Donor‐Stabilized Phosphanylboranes: A New Pathway toward Heavy 13/14/15 Parent Hydride‐Containing Compounds

ChemistryEurope, Volume 4, Issue 4, April 2026.
A new way of obtaining mixed 13/14/15 hydride containing compounds stabilized only by a Lewis base is presented. The functionalization of IDipp·BH2PH2 (IDipp = 1,3‐Bis‐(2,6‐diisopropylphenyl)‐imidazolin‐2‐ylidene) by main group electrophiles leads to the formation of the compounds [IDipp·BH2PH2E]+ [E = H, CH3 SiEt3, Ge(SiMe3)3, SnMe3) which represent a

Shedding Light on Dark Romance: Light Personalities' Reduced Rejection of Machiavellian and Sadistic Partners

Personal Relationships, Volume 33, Issue 1, March 2026.
ABSTRACT Drawing on the complementarity perspective of romantic attraction, we examined dyadic initial attraction in a speed‐dating context among individuals characterized by light and dark personality traits. As hypothesized, analyses of dating success, involving over 1.400 heterosexual dates with 128 participants, showed that Machiavellianism was ...

Bioenergetic profiles and respiratory control in mitochondrial physiology: Precision analysis of oxidative phosphorylation

Experimental Physiology, Volume 111, Issue 1, Page 179-211, 1 January 2026.
Abstract Oxidative phosphorylation (OXPHOS) is fundamental to mitochondrial function. Respirometry with living cells provides limited information compared to precision OXPHOS analysis with mitochondrial preparations, including isolated mitochondria, tissue homogenates, permeabilized tissues, and permeabilized cells.

Anharmonicity and Spectra–Structure Correlations in MIR and NIR Spectra of Crystalline Menadione (Vitamin K₃)

Molecules, 2021
Mid-infrared (MIR) and near-infrared (NIR) spectra of crystalline menadione (vitamin K3) were measured and analyzed with aid of quantum chemical calculations. The calculations were carried out using the harmonic approach for the periodic model of crystal

Scanner‐Independent Calibrations of Handheld Near‐Infrared Spectra for Robust Quality Assessment of Vanilla Pods

Journal of Food Quality, Volume 2026, Issue 1, 2026.
Vanillin is a high‐value flavor compound derived from Vanilla planifolia, whose grading in commercial supply chains remains challenging due to compositional heterogeneity of the pods and variability among handheld near‐infrared (NIR) scanners. In this study, scanner‐independent calibration models were developed for the rapid prediction of vanillin ...

Yawning as Therapy? The Potential of the Conditioned Yawn Reflex as a Novel Treatment for Insomnia Disorder

Journal of Sleep Research, Volume 34, Issue 5, October 2025.
ABSTRACT In 1986, Provine, the pioneer of yawning research wrote that ‘Yawning may have the dubious distinction of being the least understood, common human behaviour’ (p. 120); and so yawning remains some 40 years later, as something of a biological and social curiosity.
