Analysis of Adiabatic Batch Reactor
A mixture of acetic anhydride is reacted with excess water in an adiabatic batch reactor to form an exothermic reaction. The concentration of acetic anhydride and the temperature inside the adiabatic batch reactor are calculated with an initial ...

A Chemical and Enzymatic Approach to Study Site-Specific Sumoylation. [PDF]
A variety of cellular pathways are regulated by protein modifications with ubiquitin-family proteins. SUMO, the Small Ubiquitin-like MOdifier, is covalently attached to lysine on target proteins via a cascade reaction catalyzed by E1, E2, and E3 enzymes.

Optimization of wood flour acetylation by factorial design and partial least squares regression
Acetylation was performed to reduce the polarity of wood and increase its compatibility with polymer matrices for the production of composites. These reactions were performed first as a function of acetic acid and anhydride concentration in a mixture ...

Effects of different activation processes on H2O2/TAED bleaching of Populus nigra chemi-thermo mechanical pulp [PDF]
Tetra acetyl ethylene diamine (TAED) was used as an activator in H2O2 bleaching to improve bleaching efficiency. The present work was aimed at confirming different activations for various H2O2/TAED bleaching processes, including the addition of acetic ...

The Cationic Ring-Opening Polymerization of Tetrahydrofuran with 12-Tungstophosphoric Acid
The cationic ring-opening polymerization reaction of tetrahydrofuran at 20 ºC was catalyzed by H3PW12O40·13H2O as solid acid catalyst. The effect of the proportions of acetic anhydride and catalyst, reaction time and support on the polymerization ...

Synthesis and Characterization of some New Amic acid and Imides and study the Biological Activity
This study includs the synthesis of some new Amic acid and Imides, starting from the esters [S1] of Terephthalic acid which then converted to its hydrazide [S2] then to amic acid derivatives [S3-S7] and finally with imides [S8-S12].

A miniaturized, label‐free, and enzyme‐free biosensor (miR‐TFT) enables direct electrical detection of microRNA (miRNA) with single‐nucleotide specificity and a detection limit of 0.6 fM. Built on a tri‐channel In2O3/ZnO heterojunction and functionalized with bespoke peptide nucleic acid (PNA) probes, the device is robust, reusable, and compatible with
