Synthesis of a Metal Oxide by Forming Solvate Eutectic Mixtures and Study of Their Synthetic Performance under Hyper- and Hypo-Eutectic Conditions

Crystals, 2020
The synthesis of YBa2Cu3O7−x (YBCO or 123) superconductor was carried out under hyper- and hypo-eutectic conditions with different ammonium compounds, i.e., ammonium nitrate, formate, acetate, carbonate, bicarbonate, and tetramethylammonium nitrate.

Incorporation of Organic Counter‐Cations Into Poly(Heptazine Imide) Networks for Promoting Proton‐Coupled Electron Transfer During Photocatalytic H2O2 Evolution

Angewandte Chemie, EarlyView.
Incorporation of N‐based onium ions into the ionic framework of poly(heptazine imide) was obtained via protonation‐deprotonation of PHI frameworks arising from a parent Na‐containing analogue. Particularly, methylammonium moieties, through their small molecular size, hydrogen bonding capabilities and rotational mobility, appear to stabilize ...

Synthesis of ω-Chloroalkyl Aryl Ketones via C–C Bond Cleavage of tert-Cycloalkanols with Tetramethylammonium Hypochlorite

Molecules
An oxidative C–C bond cleavage of tert-cycloalkanols with tetramethylammonium hypochlorite (TMAOCl) has been developed. TMAOCl is easy to prepare from tetramethylammonium hydroxide, and the combination of TMAOCl and AcOH effectively promoted the C–C bond

Bis(tetramethylammonium) thiosulfate tetrahydrate

Acta Crystallographica Section E, 2011
The anion of the title salt, 2C4H12N+·S2O32−·4H2O, possesses approximate C3v symmetry. The water molecules themselves engage in hydrogen bonding, forming a ribbon running along the a axis; adjacent chains are linked to the ...

Spin‐On SiOx‐Assisted Inkjet Printing for Interdigitated n+ and p+ Poly‐Si/SiOx Contacts in Silicon Solar Cells With Suppressed Unintended Doping

Advanced Materials Technologies, EarlyView.
This work presents an innovative spin‐on SiOx‐assisted inkjet‐printed approach to form localized n+ and p+ poly‐Si/SiOx passivating contacts for high‐efficiency silicon solar cells within a single‐annealing step. The developed process results in a well‐defined interdigitated doping pattern, with unintended doping and cross‐doping concentrations ...

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.
