Chemoselective catalytic conversion of glycerol as a biorenewable source to valuable commodity chemicals
TL;DR: This paper provides a comprehensive review and critical analysis on the different reaction pathways for catalytic conversion of glycerol into commodity chemicals, including selective oxidation, selective hydrogenolysis, selective dehydration, pyrolysis and gasification, steam reforming, thermal reduction into syngas, selective transesterification, selective etherification, oligomerization and polymerization, and conversion of Glycerol carbonate.

Safety evaluation and risk assessment of electronic cigarettes as tobacco cigarette substitutes: a systematic review
TL;DR: This systematic review appraises existing laboratory and clinical research on the potential risks from electronic cigarette use, compared with the well-established devastating effects of smoking tobacco cigarettes to indicate that electronic cigarettes are by far a less harmful alternative to smoking.

Carbon-Catalyzed Gasification of Organic Feedstocks in Supercritical Water†
TL;DR: In this paper, the effects of temperature, pressure, reactant concentration, weight hourly space velocity, and the type of catalyst on the gasification of glucose are reported, and complete conversion of glucose (22% by weight in water) to a hydrogen-rich synthesis gas was realized at a weight hourly velocity (WHSV) of 22.2 h-1 in supercritical water at 600 °C, 34.5 MPa.

Production of acrolein from glycerol over silica-supported heteropoly acids
TL;DR: In this article, supported heteropoly acids were used as a catalyst for the dehydration of glycerol to produce acrolein and the catalytic activity depended on the types of heteropoly acid and on the size of the mesopores in the silica support.

Production of levoglucosan and glucose from pyrolysis of cellulosic materials
TL;DR: In this paper, it was found that pyrolysis proceeds at a much faster rate at the higher temperatures without detrimental effect on the yields, yielding a tar that contained 39% levoglucosan and, upon mild acid hydrolysis, gave 49% Dglucose.

The pyrolysis of cellulose and the action of flame‐retardants
TL;DR: In this article, the vacuum pyrolysis of cotton cellulose, alone or with flame-retardants, at temperatures usually near 420°, products have been identified and determined.

High-temperature pyrolysis of acetaldehyde
TL;DR: In this paper, high-temperature (>1000°K) pyrolysis of acetaldehyde (∼1% in an atmosphere of pure nitrogen) was examined in a turbulent flow reactor which permits accurate determination of the spatial distribution of the stable species.

Mixing by agitation of miscible liquids Part II
TL;DR: In this paper, the performance of several types of agitators has been studied for the mixing of miscible liquids in batch operation, and the results enabled relations containing dimensionless groups to be derived for both mixing time and power consumption.
