SMARTS-RX: a SMARTS-based representation of chemical functions for reactivity analysis

open access: yesJournal of Cheminformatics
Chemical functional group annotation provides a mechanistically meaningful framework to interpret model outcomes and guide synthetic strategies. Here, we present SMARTS-RX—a curated, hierarchical ontology of 406 SMARTS-based functional group descriptors ...

Was the steppe bison a grazing beast in Pleistocene landscapes?

open access: yesRoyal Society Open Science
The history and palaeoecology of the steppe bison (Bison priscus) remain incompletely understood despite its widespread distribution. Using dental microwear textural analysis (DMTA) and vegetation modelling, we reconstructed the diet and assessed the ...

Dietary differences in archosaur and lepidosaur reptiles revealed by dental microwear textural analysis

open access: yesScientific Reports, 2019
Reptiles are key components of modern ecosystems, yet for many species detailed characterisations of their diets are lacking. Data currently used in dietary reconstructions are limited either to the last few meals or to proxy records of average diet over

Determination of Glutathione Reductase Activity Changes Exposed to Some 2-Aminothiazole Derivatives

open access: yesCumhuriyet Science Journal, 2019
In this work, effects of concentrations rangingfrom 0 to 500 mg/L of some 2-aminothiazole derivatives such as4,4’-(disulfanediylbis(methylene))bis(thiazol-2-amine) dihyrochloride (DMTA)and 2-amino-4-(chloromethyl)thiazole hydrochloride (ACT) on ...

Effect of Consolidation Time in Hot Press Compression Molding of Continuous Carbon Fiber‐Reinforced Polyetheretherketone Composite

open access: yesPolymer Composites, EarlyView.
Influence of consolidation time on interlaminar shear strength and void content after hot press consolidation and vacuum bag only processes. ABSTRACT Processing long fiber reinforced thermoplastic composites such as polyaryletherketones with carbon fibers (CF/PEEK) has found interest in the aerospace industry due to short‐time manufacturing and ...

Robust β‐myrcene block copolymer elastomeric vitrimers

open access: yesPolymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Effect of morphology and defectiveness of graphene-related materials on the electrical and thermal conductivity of their polymer nanocomposites

open access: yes, 2016
In this work, electrically and thermally conductive poly (butylene terephthalate) nanocomposites were prepared by in-situ ring-opening polymerization of cyclic butylene terephthalate (CBT) in presence of a tin-based catalyst.
