Rigid Polyurethane Foams From Oxypropylated Wheat Straw Lignin [PDF]

open access: yes, 2013
Polyols for rigid PU foams production are derived mostly from petrochemical products but it can be replaced by polyols obtained from natural raw materials (vegetable oils, tall oil, lignin etc.). Organosolve lignin from CIMV biorefinery (France) was used

Copper‐Based Conductive Nanoinks: Scalable Synthesis via Continuous‐Flow Microwave‐Assisted Polyol Process

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Microwave‐assisted polyol synthesis in continuous flow produces metallic Cu nanoparticles, using ethylene glycol as solvent and reducing agent, lignin to stabilize the colloid and prevent oxidation, and metal‐seeds for particle size control. Metallic copper nanoparticles are a promising alternative to gold and silver in printed electronics due to their

The role of the gut microbiome in the regulation of high‐altitude adaptation

open access: yesiMeta, EarlyView.
This study is the first to elucidate mechanisms of high‐altitude adaptation from the perspective of the rumen ecosystem by using indigenous yaks and Holstein cows that have lived at high altitude since birth as comparative models. Through a systematic comparison of their rumen ecology using multi‐omics approaches—including rumen metagenomics ...

Effects of temperature, flow rate, number of stages and a heads column on congener removal in fuel‐ethanol distillation: a simulation study

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Industrial fuel‐ethanol units must remove trace volatile congeners (acetaldehyde, ethyl acetate, carbon dioxide) to meet quality requirements. In Brazilian systems, a small heads column (“Column D”) is often placed above the stripper.
