Ailís O&#x;Shea,Conall McNamara,Prajwal Rao et al.
Ailís O&#x;Shea et al.
The reaction mechanism and kinetics of the sulfuric acid catalysed ethanolysis of glucose, cellulose, xylan, and corncob were investigated using a combination of experiments and empirical reaction mechanism modelling. The experimental study...
A modular, reusable biocatalytic flow system for UDP-GlcNAc production [0.03%]
模块化、可重复使用的生物催化流系统用于UDP-GlcNAc生产
Tom L Roberts,Jonathan P Dolan,Gavin J Miller et al.
Tom L Roberts et al.
We report here the continuous flow synthesis of a high-value sugar nucleotide. Immobilisation of enzymes onto solid carriers permitted transfer of the biocatalysts into packed bed reactors to realise a continuous biocatalytic platform for t...
Enantioselective synthesis of (R)-citronellal from geraniol with an immobilised copper alcohol oxidase and ene reductase [0.03%]
香叶醇在固定化铜酒精氧化酶和烯还原酶作用下enantioselectivity合成(R)-柠檬醛
Beatrice Tagliabue,Christian M Heckmann,Rocio Villa et al.
Beatrice Tagliabue et al.
(R)-Citronellal is one of the key chiral intermediates in the synthesis of the isomer (-)-menthol, one of the most commercialised terpenoid flavours worldwide. Enzymatic approaches could represent a less energy-demanding alternative for its...
Interaction of light with gas-liquid interfaces: influence on photon absorption in continuous-flow photoreactors [0.03%]
光与气液界面相互作用及其对连续流光反应器中光吸收的影响
Jasper H A Schuurmans,Stefan D A Zondag,Arnab Chaudhuri et al.
Jasper H A Schuurmans et al.
Light interacts with gas bubbles in various ways, potentially leading to photon losses in gas-liquid photochemical applications. Given that light is a valuable 'reagent', understanding these losses is crucial for optimizing reactor efficien...
Metallic sealants increase flux and change selectivity in supported molten-salt membranes [0.03%]
金属密封剂可提高载流子并改变支持熔盐膜的选择性
Liam A McNeil,Guannan Chen,Wenting Hu et al.
Liam A McNeil et al.
Metallic sealants are widely used with high-temperature membranes. Here we show that their use in supported molten-salt membranes results in order-of-magnitude differences in CO2 flux and introduces O2 co-permeation. The 'short-circuiting' ...
