Electrochemical sensing of anions and heparin by an alkyl-chain ferrocene cationic surfactant.

Alkyl-chain ferrocene cationic surfactants (ACFcCS) can form ion-pair complexes with anions, and are then adsorbed at hydrophobic electrode surfaces or extracted to organic layers. The amount of adsorbed ACFcCS-anion complex is dependent on the anion concentration in a solution, and the anion concentration can be determined from the current intensity of the oxidation wave of the ferrocene part ...

Photoinduced charge accumulation by metal ion-coupled electron transfer.

An oligotriarylamine (OTA) unit, a Ru(bpy)3(2+) photosensitizer moiety (Ru), and an anthraquinone (AQ) entity were combined to a molecular dyad (Ru-OTA) and a molecular triad (AQ-Ru-OTA). Pulsed laser excitation at 532 nm led to the formation of charge-separated states of the type Ru(-)-OTA(+) and AQ(-)-Ru-OTA(+) with lifetimes of ≤10 ns and 2.4 μs, respectively, in de-aerated CH3CN at 25 °C. U...

Charge Transfer Scheme for Atmospheric Ice Sensing

The atmospheric icing parameters are being measured nowadays with the aid of more customized yet limited commercial equipment. The parameters include atmospheric ice detection, icing load and icing rate. The robustness of such equipment is usually under scrutiny when it comes to cold/harsh environment operations. This phenomenon was experienced consistently by the atmospheric Icing Research Tea...

Photoinduced Electron Transfer Based Ion Sensing within an Optical Fiber

We combine suspended-core microstructured optical fibers with the photoinduced electron transfer (PET) effect to demonstrate a new type of fluorescent optical fiber-dip sensing platform for small volume ion detection. A sensor design based on a simple model PET-fluoroionophore system and small core microstructured optical fiber capable of detecting sodium ions is demonstrated. The performance o...

Antimicrobial evaluation of N-alkyl betaines and N-alkyl-N, N-dimethylamine oxides with variations in chain length.

Alkyl betaines and alkyl dimethylamine oxides have been shown to have pronounced antimicrobial activity when used individually or in combination. Although several studies have been conducted with these compounds in combinations, only equimolar concentrations of the C(12)/C(12) and C(16)/C(14) chain lengths for the betaine and the amine oxide, respectively, have been investigated. This study inv...
