Crystal structure of 5-O-benzoyl-2,3-O-isopropylidene-d-ribono-1,4-lactone

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2017
In the title compound, C15H16O6, obtained from the acylation reaction between 2,3-O-isopropylidene-d-ribono-1,4-lactone and benzoyl chloride, the known absolute configuration for the lactone moiety of the ester substituent has been confirmed.

Biodegradation of 2-ethylhexyl nitrate (2-EHN) by Mycobacterium austroafricanum IFP 2173 [PDF]

open access: yesApplied and Environmental Microbiology 74 (2008) 6187-6193, 2009
2-Ethyhexyl nitrate (2-EHN) is a major additive of fuel which is used to comply with the cetane number of diesel. Because of its wide use and possible accidental release, 2-EHN is a potential pollutant of the environment. In this study, Mycobacterium austroafricanum IFP 2173 was selected among several strains as the best 2-EHN degrader.

Electrochemical behaviour of gamma hydroxybutyric acid at a platinum electrode in acidic medium [PDF]

open access: yes, 2013
The electrooxidation of Gamma Hydroxybutyric Acid (GHB) on a polycrystalline platinum electrode is studied by cyclic voltammetry in acidic medium. Two oxidation peaks, A and B, are obtained in the positive scan within the potential range of the double ...

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

open access: yesAdvanced 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.

Unlocking Lactonase Enzymes as Biocatalysts for the Deracemisation of Chiral γ‐Thiolactones

open access: yesAngewandte Chemie, EarlyView.
The application of lactonase enzymes as biocatalysts still remains underexplored. This study discloses the biocatalytic activity of two lactonases in the deracemisation of chiral C3‐substituted‐γ‐thiolactones. The biocatalyst GcL catalyses the enzymatic kinetic resolution (EKR) of C3‐amide‐thiolactones, while the rationally engineered biocatalyst N9 ...

Studies on lactone stabilities [PDF]

open access: yes, 2021
The theories of Bucourt concerning the stabilities of mono-and polycyclic compounds have been critically exarnined and modified. Ring strain (as measured by heats of combustion in the literature) may be calculated with irnproved accuracy by the modified theory.

Thermo‐Responsive Tri‐State Photonic Crystals

open access: yesAdvanced Science, EarlyView.
Tri‐state photonic crystals combine thermochromic structural color, fluorescence, and afterglow via far‐field absorption tuning, bypassing the efficiency‐lifetime trade‐off of TS‐FRET. This enables dynamic, high‐capacity anti‐counterfeiting with tunable optical states.

Quorum sensing inhibitory compounds from extremophilic microorganisms isolated from a hypersaline cyanobacterial mat [PDF]

open access: yesarXiv, 2013
In this study extremely halophilic and moderately thermophilic microorganisms from a hypersaline microbial mat were screened for their ability to produce antibacterial, antidiatom, antialgal and quorum sensing (QS) inhibitory compounds. Five bacterial strains belonging to the genera Marinobacter and Halomonas and one archaeal strain belonging to the ...

CO2‐DBU‐Triggered Photoredox‐Catalyzed Direct α‐C‐H Alkylation of Alcohols

open access: yesAdvanced Science, EarlyView.
An efficient photoinduced and metal‐free method is developed for direct α‐C–H monoalkylation of alcohols utilizing the CO2‐DBU system as the hydrogen bond acceptor (HBA) in the presence of H2O, allowing for selective functionalization of alcohols with a broad substrate scope.
