Lactonization of α-Ferrocenyl Ketocarboxylic Acids via Nucleophilic Attack of Carbonyl Oxygen

Crystals
The effects of the ferrocenyl moiety to enhance the nucleophilicity of the carbonyl group, situated at its adjacent position, have been explored in a series of α-ferrocenyl ketocarboxylic acids.

Oligomerization of Lactones

Journal of Japan Oil Chemists' Society, 1968
Preparation of oligomers of β-propiolactone (β-PL) and e-caprolactone (e-CL) having reactive functional groups such as hydroxyl, carboxyl and acid chloride groups have been studied. In order to clarify the pattern of bond fission of the lactones, reactions of β-PLwith ethanol, acetic acid and acetyl chloride were carried out with or without catalysts ...

Dual Foreign Body Response Mitigation Strategies for Implantable Glucose Sensors

Advanced Sensor Research, EarlyView.
The foreign body response negatively impacts the analytical lifetime of implantable glucose sensors due to a heightened immune response and deposition of collagen. While nitric oxide release has shown promise as a foreign body response mitigation strategy, improvement is limited by the duration of release.

DJ-1 interacts with and regulates paraoxonase-2, an enzyme critical for neuronal survival in response to oxidative stress. [PDF]

, 2014
Loss-of-function mutations in DJ-1 (PARK7) gene account for about 1% of all familial Parkinson's disease (PD). While its physiological function(s) are not completely clear, DJ-1 protects neurons against oxidative stress in both in vitro and in vivo ...

Impact of Disorder, Porosity, and Surface Chemistry of Salt Templated Carbons on Capacitance

Advanced Science, EarlyView.
Soft‐salt templating method allowed to obtain a series of tailored porous carbons for EDLCs. Neutral aqueous electrolytes enabled to reach 1.6 V. Linear dependence of ID/IG ratio vs. capacitance values has been proven. Active surface area related to carbon defects supported the Raman findings.
