Growth inhibition and morphologic changes of HeLa cells exposed to unsaturated fatty acid fraction from the liver of x-ray irradiated rabbits (OX) [PDF]

open access: yes, 1962
Biological effect of the unsaturated fatty acid fraction from the X-ray irradiated rabbit liver (OX) on HeLa cells has been observed in vitro comparing with the effect displayed on the same strain cells by the unsaturated fatty acid fraction from the non-

Deformation of unsaturated collapsible soils under suction control

open access: yesJournal of the Mechanical Behavior of Materials, 2022
Collapsible soils present significant geotechnical and structural engineering challenges worldwide. They can be found in arid or semi-arid regions and are directly affected by the multi-step wetting procedure due to the reduction of soil suction.

The Methyl Torsion in Unsaturated Compounds [PDF]

open access: yesACS Omega, 2020
How the methyl torsion transition energy in unsaturated systems is affected by its environment is investigated. It is strongly influenced by both its immediate neighborhood, (the number of methyl groups present in the molecule) and the intermolecular interactions.

Carboxylate catalyzed isomerization of β,γ-unsaturated NAC thioesters [PDF]

open access: yes, 2022
We demonstrate herein the capacity of simple carboxylate salts – tetrametylammo-nium and tetramethylguanidinium pivalate – to act as catalysts in the isomerization of β,γ-unsaturated thioesters to α,β-unsaturated thioesters.

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

open access: yesFEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Identifying true shrinkage limit of clay by updating experiments in Chinese standard GB/T 50123—2019

open access: yesYantu gongcheng xuebao, 2022
The methods to determine the true shrinkage limit of clay are proposed by updating both the testing procedure and the data processing of the shrinkage limit and shrinkage test methods in the Chinese standard for geotechnical testing method (GB/T 50123 ...

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Synthesis of an unsaturated diether analogue of phosphatidyl ethanolamine

open access: yesJournal of Lipid Research, 1966
A synthesis of racemic diether analogues of glyceryl phosphatides is reported which is applicable to unsaturated aliphatic substituents. The ``oleyl'' diether analogue of phosphatidyl ethanolamine has been synthesized.
