Characterization of a SAM-dependent fluorinase from a latent biosynthetic pathway for fluoroacetate and 4-fluorothreonine formation in Nocardia brasiliensis [v1; ref status: indexed, http://f1000r.es/2tz]

open access: yesF1000Research, 2014
Fluorination has been widely used in chemical synthesis, but is rare in nature. The only known biological fluorination scope is represented by the fl pathway from Streptomyces cattleya that produces fluoroacetate (FAc) and 4-fluorothreonine (4-FT).

Synthesis of thorium tetrafluoride (ThF4) by ammonium hydrogen difluoride (NH4HF2)

open access: yesNuclear Engineering and Technology, 2019
The present study aims to investigate the fluorination of thorium oxide (ThO2) by ammonium hydrogen difluoride (NH4HF2). Fluorination was performed at room temperature by mixing ThO2 and NH4HF2 at different molar ratios, which was then left to react for ...

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

open access: yesAdvanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Fluorination with Complex Fluorine Compounds

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1969
鉄,アルミニウム,アンチモン,ケイ素,チタンなどの6配位錯フッ化物によるハロゲン交換フッ素化反応について研究した。フッ素化の対象としては,四塩化炭素,クロロホルム,ヘキサクロルエタンなどの有機塩素化合物をえらび,オートクレープ中で250ないし350℃で2時間ないし4時間反応させた。この結果,鉄,アンチモン,アルミニウムなどの錯フッ化勃の活性が大きく,ケイ素の錯フッ化物の活性はこれらについだ。これに対し,チタソの錯フッ化物は不活性であることがわかった。鉄,アンチモン,アルミニウムの錯フッ化物の活性が大きいことは,これら錯フッ化物がリガンド交換活性な外軌道または高スピン錯塩であることによるものと考えられる。実際に,反応後の固体をX線回折分析により調べたところ,低配位錯塩NaAIF4 ...

Controlled Hydrophilic–Hydrophobic Transition of PET Films via Fluorination and Drying

open access: yesPhyschem
Polyethylene terephthalate (PET) films were modified by direct fluorination using fluorine gas at room temperature and 660 torr for reaction times ranging from 10 min to 5 h. Some of the fluorinated samples were dried at 70 °C for 7 days.
