Atmospheric Chemistry of 2-Methoxypropene and 2-Ethoxypropene: Kinetics and Mechanism Study of Reactions with Ozone

open access: yesAtmosphere, 2018
Rate coefficients at ambient temperature and atmospheric pressure for the reaction of ozone with 2-methoxypropene (2-MPE) and 2-ethoxypropene (2-EPE) were determined in an evacuable 100 L Teflon reaction chamber using absolute and relative rate methods ...

Understanding Svocs [PDF]

open access: yes, 2011
Semi-volatile organic compounds (SVOCs) are an important class of indoor pollutants that are of great health concern. However, they have not received much attention within the ASHRAE community.

Differentiating the Synergistic Interactions Between Li+ Salts and Cyclic to Linear Carbonate Ratios to Enable Wide‐Temperature Performance of Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The coordination in carbonate solvents and degradation products of lithium difluoro(oxolato) borate (LiDFOB) salt enables sufficient passivation of both LiNi0.8Mn0.1Co0.1O2 (NMC811) cathode and graphite anode in the absence of ethylene carbonate (EC).

Addition of Chloromethyl Methyl Ether to Isoprene and the Prepation of Isogeranyl Methyl Ether

open access: yesJournal of Japan Oil Chemists' Society, 1975
The cationic addition of chloromethyl methyl ether to isoprene in the presence of metal halides was investigated in order to obtain the 1, 4-adduct, 1-chloro-3-methyl-5-methoxypentene-2. It was found that the addition of small amounts of ethyl alcohol caused a large increase in the yield of the adduct, especially in the case of stannic chloride ...

Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

Distribution of miliacin (olean-18-en-3β-ol methyl ether) and related compounds in broomcorn millet (Panicum miliaceum) and other reputed sources: Implications for the use of sedimentary miliacin as a tracer of millet [PDF]

open access: yes, 2013
International audienceUsing sedimentary miliacin (olean-18-en-3β-ol methyl ether) as a molecular tracer of the history of Panicum miliaceum (broomcorn millet) cultivation depends upon broomcorn millet being sedimentary miliacin's dominant source. It also

High‐Entropy Doped KTiOPO4‐Type Vanadium‐Based Fluorophosphate Cathodes for High‐Energy Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a high‐entropy doped NaV0.95 (Fe, Mn, Ni, Al, Ca)0.05PO4F cathode, which enables the whole utilization of Na ions, enhances the reaction kinetics without carbon coating, and realizes a solid‐solution reaction mechanism with a single‐crystal structure.

Acetonitrile-hydrochloric acid hydrolysis of gangliosides for high performance liquid chromatographic analysis of their long chain bases.

open access: yesJournal of Lipid Research, 1983
An improved method for the hydrolysis of long chain bases from gangliosides with aqueous acetonitrile-HCl is described. The long chain bases released from brain gangliosides were derivatized with biphenylcarbonylchloride and resolved by high performance ...
