Acetic Acid Assisted Crystallization Strategy for High Efficiency …
2020年1月23日 · Here, a simple method is introduced to prepare perovskite film with excellent optoelectronic property by using acetic acid (Ac) as an antisolvent to control perovskite crystallization. Results from a variety of characterizations suggest that the small amount of Ac not only reduces the perovskite film roughness and residual PbI 2 but also ...

Acetic acid - Wikipedia
Acetic acid / ə ˈ s iː t ɪ k /, systematically named ethanoic acid / ˌ ɛ θ ə ˈ n oʊ ɪ k /, is an acidic, colourless liquid and organic compound with the chemical formula CH 3 COOH (also written as CH 3 CO 2 H, C 2 H 4 O 2, or HC 2 H 3 O 2). Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar ...
Acetic acid - wikidoc
Crystallized acetic acid. Vinegar was known, early in civilization, as the natural result of air exposure of beer and wine, as acetic acid-producing bacteria are present throughout the world.
Separation of Acetic Acid from Acetic Acid-Water Mixture by Crystallization
2013年3月27日 · The acetic acid was successfully separated by single-stage melt crystallization. As the sweating fraction is increased, the crystalline layers grown at lower cooling rates are purified more highly. Eventually, the crystallization rate …
Here, we introduce acetic acid (Ac) as the additive for the antisolvent (chlorobenzene) solution process for the fabrication of mixed halides triple-cation Cs 0.05FA 0.80MA 0.15Pb(I 0.85Br 0.15) 3 perovskite. Our results show that the additive helps to modify perovskite film morphology producing ultra-uniform surface.
The crystal structure of acetic acid - Acta Crystallographica
Acetic acid crystals are orthorhombie, space group Pna21, with a ---- 13-324-0.02, b = 4-08~0-01, C = 5'774-0'01 /~ from single-crystal X-ray diffraction. The structure is similar to that of formic acid with molecules linked into infinite chains by hydrogen bonds.
Crystallization from glacial acetic acid melt via laser ablation
2021年4月7日 · In this work, laser ablation-induced crystallization of a single-component system was demonstrated using a melt of glacial acetic acid. We systematically investigated the dependence of the crystallization probability on laser energy, pulse duration, and beam profile.

[PDF] The crystal structure of acetic acid | Semantic Scholar
The structural and thermodynamic backgrounds for the crystallization behaviour of racemates have been investigated using 2-phenoxypropionic acid as an example and it is shown that hydrogen-bonded dimers that form over crystallographic symmetry elements exist in all but the structure of the pure enantiomer.
