The solvent effect, preferential solvation of metformin hydrochloride in binary mixed solvents of methanol/ethanol + water mixtures from 278.15 K to 323.15 K by Adel Noubigh, Abdalazeem A. Omar, Manef Abderrabba

“…This enhanced solvation by water may be attributed to the disordered structure of the alcohol molecules surrounding the polar regions of MET-HCl. The influence of solvent composition on the molar fraction solubility of MET-HCl was investigated using the Kamlet-Taft linear solvation energy relationship model. …”

Curvature Determination Method for Diverging Acoustic Lens of Underwater Acoustic Transducer by Minze Li, Mingzhen Xin, Fanlin Yang, Yu Luo, Jinpeng Liu, Niuniu Wu

“…Underwater acoustic transducers need to expand the coverage of acoustic signals as much as possible in most ocean explorations, and the directivity indicators of transducers are difficult to change after the device is packaged, which makes the emergence angle of the underwater acoustic transducer limited in special operating environments, such as polar regions, submarine volcanoes, and cold springs. …”

A dataset on bathymetry and hydrology of an emerging periglacial lagoon in Svalbard, ArcticMendeley Data by Andrius Šiaulys, Aleksej Šaškov, Greta Kilmonaitė, Dzmitry Lukashanets, Tobia Politi, Aurelija Samuilovienė, Anastasija Zaiko, Sergej Olenin

“…There is limited data on the geomorphology and hydrology of these novel formations, primarily because conducting research in remote polar regions is logistically challenging and expensive.We present hydrological and bathymetric data collected in 2022-2024 in a newly formed lagoon located in the western part of Spitsbergen (Svalbard), between Eidembreen glacier and Eidembukta bay. …”
