Terahertz Raman Optical Activity Reveals Emergent Supramolecular Chirality in Mononucleotide G‐quadruplexes

Chemistry–Methods, EarlyView.
Self‐assembly of guanosine‐5′‐monophosphate into G‐quadruplexes induces a cation‐specific (sodium vs. potassium), intense terahertz Raman optical activity signal. The supramolecular helical arrangement gives rise to a distinct chiral vibrational signature in the low‐frequency region.

Spin‐Crossover in a Dinuclear Iron(II) Complex on Highly Oriented Pyrolytic Graphite: An X‐Ray Absorption Spectroscopy Study

ChemPhysChem, EarlyView.
This study investigates a spin‐crossover dinuclear Fe(II) complex deposited as a thin film under ultrahigh‐vacuum conditions by a pulsed layer injection technique. Its temperature‐dependent switching behavior, light‐induced excited spin‐state trapping, soft‐X‐ray‐induced excited spin‐state trapping, and temperature‐ and light‐induced spin crossover ...

A Critical Overview of Common Foodborne Toxicants and Methods for Their Reliable Detection

Food Frontiers, EarlyView.
ABSTRACT Food is an essential commodity for human health. However, toxicants such as mycotoxins, heavy metals, acrylamide, and pesticides can be present in food either naturally or through processing, packaging, or some anthropogenic activities. A thorough review of carefully selected studies revealed that climate change and pandemics have led to an ...

Coherent Terahertz Hyper‐Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
In this paper, we review our recent discovery of a novel nonlinear effect in the terahertz frequency range, which we have termed terahertz hyper‐Raman (THYR) spectroscopy. This technique shares many characteristics with conventional hyper‐Raman spectroscopy but is applied within the THz spectrum.
