Synergy Engineering of d‐Band Center and Multi‐Phase Interface Charge Transport in Ternary Co3O4/Pt/Bi2MoO6 Hierarchical Heterojunction Arrays for Superior VOCs Sensing

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel ternary Co3O4/Pt/Bi2MoO6 hierarchical heterojunction array is designed, which exhibits an impressive gas sensing activity towards volatile organic compounds (VOCs), triethylamine. The design of ternary Co3O4/Pt/Bi2MoO6 hierarchical heterojunction not only optimizes the d‐band center and thus gas molecule adsorption activity on gas–solid ...

The effect of flooding on the exchange of the volatile C₂-compounds ethanol, acetaldehyde and acetic acid between leaves of Amazonian floodplain tree species and the atmosphere [PDF]

, 2008
The effect of root inundation on the leaf emissions of ethanol, acetaldehyde and acetic acid in relation to assimilation and transpiration was investigated with 2–3 years old tree seedlings of four Amazonian floodplain species by applying dynamic cuvette

Stereoselective Chemoenzymatic Synthesis Metaraminol Involving Gold‐Catalysed Alkyne Hydration and Carbonyl Biotransamination

European Journal of Organic Chemistry, EarlyView.
A chemoenzymatic synthesis of (1R,2S)‐metaraminol was developed by combining gold(I)‐catalysed alkyne hydration and stereoselective biotransamination in a sequential one‐pot process. Various phenol protection strategies were considered in oxidation‐reduction sequences, providing access to enantiopure propargylic alcohols as starting materials for ...

Nature's Starships II: Simulating the Synthesis of Amino Acids in Meteorite Parent Bodies

, 2015
Carbonaceous chondrite meteorites are known for having high water and organic material contents, including amino acids. Here we address the origin of amino acids in the warm interiors of their parent bodies (planetesimals) within a few million years of ...

Tautomerization Kinetics of Thiouracils at Low Temperatures Driven Solely by Quantum‐Mechanical Tunnelling: Predictions of Suitable Candidates for Future Experiments

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT In the past two decades numerous experiments have been conducted on the kinetics of reactions occurring at low temperatures on inert matrices. In particular, unimolecular proton‐transfer photo‐reactions of compounds containing a carbon–sulfur double bond, or thione group C═S, can lead to the formation of higher energy isomers or tautomers with

Poly(O‐Propargyl‐N‐Amino Carbamate), a Reactive Polymer to Underpin Biomedical Applications of Poly(acetylene)s

Macromolecular Rapid Communications, EarlyView.
We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...
