The large scale recycling of lithium ion batteries (LIBs) is essential to satisfy global demands for the raw materials required to implement this technology as part of a clean energy strategy. However, despite what is rapidly becoming a cri...
Cellulose dissolution and gelation in NaOH(aq) under controlled CO2 atmosphere: supramolecular structure and flow properties [0.03%]
控制二氧化碳气氛下氢氧化钠水溶液中纤维素的溶解与成凝胶态：超分子结构与流变性质研究
Guillermo Reyes,Alistair W T King,Tetyana V Koso et al.
Guillermo Reyes et al.
We investigate the interplay between cellulose crystallization and aggregation with interfibrillar interactions, shear forces, and the local changes in the medium's acidity. The latter is affected by the CO2 chemisorbed from the surrounding...
Controlled hydrogenation of a biomass-derived platform chemical formed by aldol-condensation of 5-hydroxymethyl furfural (HMF) and acetone over Ru, Pd, and Cu catalysts [0.03%]
负载Ru、Pd和Cu催化剂上由5-羟甲基糠醛(HMF)和丙酮缩合所得平台化合物的可控氢化反应

Elise B Gilcher et al.
We studied the hydrogenation at temperatures from 313 - 393 K of a biomass-derived platform molecule, 5-hydroxymethyl furfural (HMF)-Acetone-HMF (HAH) over Pd, Ru, and Cu based catalysts. HAH was selectively hydrogenated to produce partiall...
Assessing the environmental benefit of palladium-based single-atom heterogeneous catalysts for Sonogashira coupling [0.03%]
基于钯的单原子非均相催化剂在索尼加希拉偶联反应中的环境效益评估

D Faust Akl et al.
The Pd-Cu catalysed Sonogashira coupling of terminal alkynes and aryl halides is a cornerstone synthetic strategy for C-C bond formation. Homogeneous organometallic systems conventionally applied are typically not reusable and require effic...
Synthesis of performance-advantaged polyurethanes and polyesters from biomass-derived monomers by aldol-condensation of 5-hydroxymethyl furfural and hydrogenation [0.03%]

Hochan Chang,Elise B Gilcher,George W Huber et al.
Hochan Chang et al.
Functional polyurethanes and polyesters with tunable properties were synthesized from biomass-derived 5-hydroxymethyl furfural (HMF)-Acetone-HMF (HAH) monomers. HAH can be selectively hydrogenated over Cu and Ru catalysts to produce partial...
Choline chloride-ethylene glycol based deep-eutectic solvents as lixiviants for cobalt recovery from lithium-ion battery cathode materials: are these solvents really green in high-temperature processes? [0.03%]
氯化胆碱-乙二醇基深吴德溶剂用于从锂离子电池正极材料中回收钴：在高温过程中，这些溶剂真的环保吗？
Nand Peeters,Kwinten Janssens,Dirk de Vos et al.
Nand Peeters et al.
Deep-eutectic solvents (DESs) are often considered to be safe, eco-friendly and non-toxic solvents. Due to these green credentials, they are increasingly being studied for application in metal recycling processes. One example is their use a...
Highly regioselective surface acetylation of cellulose and shaped cellulose constructs in the gas-phase [0.03%]
气相条件下纤维素和成型纤维素构建基元的高度区域选择性表面乙酞化
Tetyana Koso,Marco Beaumont,Blaise L Tardy et al.
Tetyana Koso et al.
Gas-phase acylation is an attractive and sustainable method for modifying the surface properties of cellulosics. However, little is known concerning the regioselectivity of the chemistry, i.e., which cellulose hydroxyls are preferentially a...
