Extracting Acetic Acid from Bio-Oil Using TOA [PDF]
, 2013 采用三正辛胺(TOA)作为络合剂,异辛醇和煤油分别作为助溶剂和稀释剂,对生物油中的乙酸进行了络合萃取研究。考察了TOA体积分数、异辛醇浓度、萃取剂与生物油轻馏分体积比以及温度对乙酸萃取率的影响,结果表明:温度为0℃,萃取体系为40%TOA+40%异辛醇+20%煤油(各组分浓度均为体积分数,下同),萃取剂与生物油轻馏分体积比为3∶1时,乙酸的一次萃取率较高,可达74.6%。Complexation extraction with trioctylamine( TOA) as solvent for the

Advanced Computing, Volume 1, Issue 1, December 2026.Agentic workflows will need a principled account of how data relates to scientific inference. We benchmark thirteen off‐the‐shelf compression implementations; the best already sits within 2.5×$\times$ of the entropy bound. We propose inference‐sufficient representations: model‐based representation, employing abductive inference, can reduce storage a ...

Late Cenozoic Sediment Provenance in the Northern Canterbury Basin, Aotearoa New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.Late Cenozoic strata of the northern Canterbury Basin record uplift and erosion of mountain ranges adjacent to the transition from oblique subduction to strike‐slip on the Australian–Pacific plate boundary. Using the provenance of conglomerate clasts and sandstone samples, we reconstruct sediment transport pathways and, by inference, exhumation and ...

Forecasting Cascading and Compounding Flood Risk From Earthquake‐Induced Ground Deformation
Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.ABSTRACT Large earthquakes can disrupt river systems and produce abrupt, unforeseen changes in flood risk. Forward modelling of earthquake‐related surface deformation and its influence on inundation extent, depth, and frequency enables pre‐emptive assessment of exposure to this compound hazard.

Solar Heating of the Arctic Ocean Driven by Changes to Sea Ice Albedo
Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.Abstract The sea ice albedo feedback is the process by which Arctic warming causes sea ice retreat, which due to the reduction in surface albedo leads to further Arctic warming through increased solar absorption. This definition, however, neglects important associated changes in cloud cover that can mitigate this effect, as well as covariant changes in
