Cellulosic materials as biopolymers and supercritical CO2as a green process: chemistry and applications [PDF]

open access: yes, 2012
In this review, we describe the use of supercritical CO2 (scCO2) in several cellulose applications. The focus is on different technologies that either exist or are expected to emerge in the near future.

Glycerol as a cheap, safe and sustainable solvent for the catalytic and regioselective β,β-diarylation of acrylates over palladium nanoparticles [PDF]

open access: yes, 2010
Herein we show that glycerol can be considered as a promising cheap and green solvent for the regioselective β,β-diarylation of alkenes. Whereas this reaction is generally catalyzed under an inert atmosphere by expensive phosphine or carbene-palladium ...

Selective synthesis of meta-phenols from bio-benzoic acids via regulating the adsorption state

open access: yesiScience, 2023
Summary: Phenols are important building blocks widely applied in many fields. The pronounced orientational effect of the phenolic hydroxyl group makes achieving selective synthesis of meta-phenols challenging.

A theoretical investigation of the reaction between the amidogen, NH, and the ethyl, C2H5, radicals: a possible gas-phase formation route of interstellar and planetary ethanimine [PDF]

open access: yes, 2018
The reaction between the amidogen, NH, radical and the ethyl, C2H5, radical has been investigated by performing electronic structure calculations of the underlying doublet potential energy surface. Rate coefficients and product branching ratios have also

The safer chemical design game. Gamification of green chemistry and safer chemical design concepts for high school and undergraduate students

open access: yesGreen Chemistry Letters and Reviews, 2018
Green chemistry can strongly attract students to chemistry. We, therefore, developed a green chemistry educational game that motivates students at the undergraduate and advanced high school levels to consider green chemistry and sustainability concerns ...

Bromine radical as a visible-light-mediated polarity-reversal catalyst

open access: yesiScience, 2021
Summary: Polarity-reversal catalysts enable otherwise sluggish or completely ineffective reactions which are characterized by unfavorable polar effects between radicals and substrates. We herein disclose that when irradiated by visible light, bromine can

Representation and use of chemistry in the global electronic age. [PDF]

open access: yes, 2004
We present an overview of the current state of public semantic chemistry and propose new approaches at a strategic and a detailed level. We show by example how a model for a Chemical Semantic Web can be constructed using machine-processed data and ...
