In-situ, real time gas composition measurements for SOFC's using laser spectroscopy [PDF]

open access: yes, 2010
The use of standard gas composition measurement techniques, such as gas chromatography, in large scale solid oxide fuel cells (SOFC's) operating at high temperatures can be both complex and time consuming.

Processing waste printed circuit boards for material recovery [PDF]

open access: yes, 2007
PURPOSE We have investigated the use of pyrolysis for the processing of waste printed circuit boards (PCBs). The aim was to make the process of separating the organic, metallic, and glass fibre fractions of PCBs much easier and therefore make ...

Deciphering Small Molecule Diffusion Parameters Across Light Responsive Polymersome Membranes

open access: yesAdvanced Functional Materials, EarlyView.
Light‐responsive polymersomes bearing donor–acceptor Stenhouse adducts (DASAs) enable programmable control over small‐molecule transport across synthetic membranes. By systematically varying DASA density, an optimal functionalization regime is identified that maximizes light‐gated permeability.

Directed Message-Passing Neural Networks for Gas Chromatography

open access: yesSeparations
In this paper, the directed message-passing neural network architecture is used to predict several quantities of interest in gas chromatography: retention times, Clarke-Glew 3-point thermodynamic parameters for simulation, and retention indices.

Identification of a Widespread Palmitoylethanolamide Contamination in Standard Laboratory Glassware. [PDF]

open access: yes, 2017
Introduction: Fatty acid ethanolamides (FAEs) are a family of lipid mediators that participate in a host of biological functions. Procedures for the quantitative analysis of FAEs include organic solvent extraction from biological matrices (e.g., blood ...

Effect of particle size on the surface properties and morphology of ground flax [PDF]

open access: yes, 2013
Flax fibers were ground with a ball-mill and four fractions with different size ranges were collected by sieving. These were tested for water sorption, degree of polymerization (DP), copper number, hydroxyl number and analyzed by X-ray diffraction (XRD),

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

open access: yesAdvanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Research Progress on Stable Isotope Online Testing Technology for Organic Contaminants

open access: yesYankuang ceshi, 2013
Compound-specific isotope analysis (CSIA) online is an indispensable key technique for identifying the sources of organic contaminants in the environment and characterizing their transformation processes, but there are still some problems in practical ...
