Artificial Receptor in Synthetic Cells Performs Transmembrane Activation of Proteolysis

open access: yesAdvanced Biology, EarlyView.
Transmembrane signaling is the hallmark of living cells and is among the highest challenges for the design of synthetic cells. Herein, an artificial receptor based on the chemistry of self‐immolative linkers is used to communicate information across the lipid bilayer, for transmembrane activation of enzymatic activity. Abstract The design of artificial,

Spatiotemporal Control Over Protein Release from Artificial Cells via a Light‐Activatable Protease

open access: yesAdvanced Biology, EarlyView.
Stimulus‐responsive protein release is essential for intercellular communication. Mimicking this functionality in artificial cells is promising to study the working principles of cellular signaling. Herein, an engineered light‐activatable protease is implemented in a coacervate‐based artificial cell platform to establish user‐defined spatiotemporal ...

Stability studies of coal liquid products using high performance liquid chromatography [PDF]

open access: yes, 1999
The storage stability of coal liquids is of great importance if coal liquefaction products are to replace petroleum products. It has been reported that gum formation occurs in coal-derived liquids during storage to a level at which it becomes a handling ...

Light‐Triggered Protease‐Mediated Release of Actin‐Bound Cargo from Synthetic Cells

open access: yesAdvanced Biology, EarlyView.
TEV Prtoease‐mediated Releasable Actin‐binding Protein (TRAP) is a protein‐based platform consisting of a cargo tightly bound to reconstituted actin networks in synthetic cells which can be proteolyticly released from the bound actin, followed by its secretion through membrane translocation mediated by a cell‐penetrating peptide.

A Preliminary Study of Oxidation of Lignin from Rubber Wood to Vanillin in Ionic Liquid Medium [PDF]

open access: yesarXiv, 2013
In this study, lignin was oxidised to vanillin by means of oxygen in ionic liquid (1,3-dimethylimidazolium methylsulphate) medium. The parameters of the oxidation reaction that have been investigated were the following: concentration of oxygen (5, 10, 15 and 20 ft3 h-1), reaction time (2, 4, 6, 8 and 10 h) and reaction temperature (25, 40, 60, 80 and ...

Optimal Experimental Designs for Estimating Henry's Law Constants via the Method of Phase Ratio Variation [PDF]

open access: yesarXiv, 2016
When measuring Henry's Law constants ($k_H$) using the phase ratio method via headspace gas chromatography (GC), the value of $k_H$ of the compound under investigation is calculated from the ratio of the slope to the intercept of a linear regression of the the inverse GC response versus the ratio of gas to liquid volumes of a series of vials drawn from
