Сocrystals of betulin with suberic acid: mechanochemical synthesis and thermal behavior [PDF]

open access: yesMATEC Web of Conferences, 2021
In this work, the cocrystals of betulin with suberic acid were prepared by liquid-assisted grinding method using solvents of different polarity. The formation of cocrystals was confirmed by means of powder X-ray diffraction, IR spectroscopy and thermal ...

Features of the formation of conductive films during thermal and laser sintering of silver nanoparticles stabilized by an ethoxylated carboxylic acid [PDF]

open access: yesMATEC Web of Conferences, 2021
Silver nanoparticles (Ag NPs) of ~ 6 nm in size were synthesized by the reduction of silver 2-[2-(2-methoxyethoxy)ethoxy]acetate by benzyl alcohol acting both as the solvent and as the reducer.

Charge polarity-dependent ion-insertion asymmetry during electrochemical doping of an ambipolar π-conjugated polymer

open access: yesNature Communications, 2022
The influence of ion-sidechain interactions on ion-insertion energetics in organic mixed ionicelectronic conductors (OMIECs) is not well understood. The authors show that a Gutmann Donor/Acceptor number framework captures ion-sidechain interactions and ...

Microtubular solid oxide fuel cells with a two-layer LSCF/BSCFM5 cathode

open access: yesGreen Carbon, 2023
In this study, we present the development of microtubular solid oxide fuel cells (MT-SOFC) with a two-layer cathode: a composite cathode functional layer (CFL) adjacent to the buffer layer (BL) and a cathode current-collecting layer (CCCL).
