Hydrophobic, UV resistant and dielectric polyurethane-nanolignin composites with good reprocessability

Materials & Design, 2020
Lignin nanoparticles (LNP) were obtained by an acidolysis process from corn pristine lignin. X-ray photoelectron spectroscopy (XPS) and radical scavenging activity (RSA) of the free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) confirmed a significant ...

Reproductive and nutritional management on ovarian response and embryo quality on rabbit does [PDF]

, 2014
Rabbit does in modern rabbitries are under intensive reproductive rhythms. Females are high milk producers with high energetic expenses due to the extensive overlap between lactation and gestation. This situation leads to a negative energy balance with a

Bio‐Inspired Cascade Photocatalysis on Fe Single‐Atom Carbon Nitride Upcycles Plastic Wastes for Effective Acetic Acid Production

Advanced Energy Materials, EarlyView.
This work demonstrates a novel cascade photocatalysis concept using Fe single‐atom catalysts (Fe@C3N4 SAC) to directly upcycle plastics (PET, PP, PE, PVC) into valuable acetic acid at ambient conditions. Inspired by microbial degradation, the bifunctional cascade photocatalyst combines Fenton‐like oxidation and CO2 photoreduction, as validated by ...

Functional Group Analysis of Reaction Products from Thermolysis of Lignin in Ethylene Glycol and Diethylene Glycol.

Journal of The Japan Petroleum Institute, 1994
エチレングリコールおよびジエチレングリコール中におけるリグニンの熱分解反応について研究した。反応温度573Kと623Kにおいて3時間反応を行った。ジエチレングリコール中, 反応温度573Kでの反応以外では, 生成物は2液相に分離した。下相はグリコールが主成分で, その他に水溶性の生成物が含まれており, 上相は黒色のオイル状の液体であった。元素分析値, 1H-NMRおよび13C-NMR測定により水素および炭素の分布を定量し, 官能基濃度解析法により生成物中に含まれていると推定される13種類の官能基の濃度を決定した。解析に際して2種類の解析法について検討した: 方法1は解析データとして元素分析値と1H-NMRデータを用いる方法であり, 方法2では元素分析値, 1H-NMRデータのほかに13C ...

In situ polymerisation of isoeugenol as a green consolidation method for waterlogged archaeological wood [PDF]

, 2017
Waterlogged archaeological wood is often in need of consolidation prior to drying to prevent shrinkage and cracking of the object. There is a need for new greener materials (than for example polyethylene glycol) and methods for consolidation to be ...
