“…Particularly, a red-shift from 1189 to 1182 cm −1 representing N-H bending was observed. It is possibly induced by the change in N-H vibration mode or the bond length of N-H 46, 47 , in response to the interfered H-bond of ACE2 after recognizing SARS-CoV-2 spike protein. The crystal structure of SARS-CoV-2 spike RBD bound to the ACE2 receptor indicates the networks of hydrophilic interactions at RBD/ACE2 interfaces 33 , which exhibits a conceivable existence of hydrogen bond elucidating the strength change of N-H bond 38 and explains the Raman spectral red-shift from1189 to 1182 cm −1 .…”

In this study, a new optical method is presented to determine the concentrations of NaCl and glucose aqueous solutions by using a thermo-elastic optical indicator microscope. By measuring the microwave near-field distribution intensity, concentration changes of NaCl and glucose aqueous solutions were detected in the 0–100 mg/ml range, when exposed to microwave irradiation at 12 GHz frequency. Microwave near-field distribution intensity decreased as the NaCl or glucose concentration increased due to the changes of the absorption properties of aqueous solution. This method provides a novel approach for monitoring NaCl and glucose in biological liquids by using a CCD sensor capable of visualizing NaCl and glucose concentrations without scanning.

Study of structure and optical properties of magnesium ammonium phosphate hexahydrate crystal known as struvite is presented. Experimentally determined infrared (IR) and ultraviolet–visible (UV–vis) spectra are compared with the theoretical predictions of density functional methods. Examination of the interatomic bond lengths, Mulliken atomic charges, and binding energies of water in the magnesium hexahydrate cation, together with the analysis of the hydrogen bond pattern have allowed us to explain a special feature of the IR spectrum of struvite, a blueshift of the band corresponding to the O–H stretching mode. This mode has been assigned to a “dangling” hydroxyl group in one of the water molecules in magnesium hexahydrate. Using experimentally obtained UV–vis spectrum and performing Tauc plots analysis, optical bandgap of struvite has been narrowed to a range from 5.92 to 6.06 eV.
