36. Polyiodide of dimethylglycine (DMG-½H···½H-DMG)(I3)(I2)

Polyiodides have emerged as compounds of interest both for their practical application and in the context of supramolecular chemistry. In the synthesis of halogenometallates the incorporation of polyiodide anions leads to an increase of absorption in the visible region and helps to achieve a narrower bandgap which was additional motivation to investigate polyiodides independently. We have...

37. Halogenostannates of glycine, sarcosine, dimethylglycine, betaine and -alanine

Halide organic-inorganic materials were classified as attractive semiconducting materials [1]. Such hybrid materials with amino acids are proposed for this aim [2]. Among these, halogenostannates demonstrated an unprecedented level of tunability in bandgaps across the entire visible spectrum [3]. We hereby present seven new halogenostannates with amino acids glycine (Gly), sarcosine (Sar),...

39. Sonochemical Synthesis of Copper Nanomaterials from 3D Printing Waste

Additive manufacturing (AM) waste high in copper was employed as an eco-friendly precursor in this study for the formation of luminescent copper-containing nanomaterials. The sonochemical process using a bath-type ultrasonic reactor (40 minutes, 99% power) was applied to convert 3D-printing metallic waste into nanostructures based on oxides using acoustic cavitation. Three different additive...

51. Vibrational spectroscopy of chlorinated and dechlorinated graphene layers

Hovhannes Badalyan (A.I. Alikhanyan National Science Laboratory (Yerevan Physics Institute), 2 Alikhanyan Brothers, Yerevan, Armenia, 0036)

19/06/2025, 16:00

Graphene, a two-dimensional material composed of a single layer of carbon atoms in a honeycomb lattice, has garnered immense interest for its exceptional mechanical strength, electrical conductivity, and thermal transport properties [1, 2]. In this work, we introduce a novel chlorination protocol—using a specialized liquid-phase treatment—to covalently attach chlorine atoms to graphene, and...

30. The Effect of Ultrasound Radiation on Potassium Iodide Solutions

Aram Davtyan (Nalbandyan Institute of Chemical Physics of the NAS RA)

19/06/2025, 16:20

The introduction of ultrasonic vibrations into aqueous solutions can, under certain conditions, lead to the emergence of cavitation, which is expressed in the emergence and collapse of vapor-gas bubbles. In this case, the relatively low average energy of ultrasonic vibrations is concentrated in a small volume of vapor-gas bubbles, reaching high values. As a result, high temperatures (on the...
