Chemical Activation of Lignocellulosic Precursors and Residues: What Else to Consider? [PDF]
Molecules, 2022 This paper provides the basis for understanding the preparation and properties of an old, but advanced material: activated carbon. The activated carbons discussed herein are obtained from “green” precursors: biomass residues.

Removal of Methylene Blue and Methyl Red from Aqueous Solutions Using Activated Carbons Obtained by Chemical Activation of Caraway Seed [PDF]
Molecules, 2023 In this study, activated carbons were produced through the chemical activation of caraway seeds using three different activators: Na2CO3, K2CO3, and H3PO4. A 1:2 weight ratio of precursor to activator was maintained in every instance.

Removal of Malachite Green Dye from Aqueous Solution by a Novel Activated Carbon Prepared from Baobab Seeds Using Chemical Activation Method [PDF]
MoleculesTwo activated carbons were synthesized from baobab seeds (BSs) using two activators, sulfuric acid (BS-AAC) and sodium hydroxide (BS-BAC), for dye removal from aqueous solutions. Malachite green (MG) was used as a model dye.

Review on Activated Carbons by Chemical Activation with FeCl3 [PDF]
Journal of Carbon Research, 2020 This study reviews the most relevant results on the synthesis, characterization, and applications of activated carbons obtained by novel chemical activation with FeCl3. The text includes a description of the activation mechanism, which compromises three different stages: (1) intense de-polymerization of the carbon precursor (up to 300 °C), (2 ...

Nucleation of Chemically Active Droplets
Physical Review Letters, 2023 Driven chemical reactions can control the macroscopic properties of droplets, like their size. Such active droplets are critical in structuring the interior of biological cells. Cells also need to control where and when droplets appear, so they need to control droplet nucleation.

Valorization of Waste Tires by Pyrolysis and Activation Processes
Applied Sciences, 2021 The problems related to the increase in the generation of discarded tires demonstrate the need for profitable, efficient, cost-effective, and sustainable processes for their waste management. In particular, the valorization of pyrolytic solids for energy

On Chemical Activation by Collisions [PDF]
Proceedings of the National Academy of Sciences, 1927 In the case of first order unimolecular gas reactions, such as the decomposition of nitrogen pentoxide, there is a well-known, theoretical difficulty (1) in discovering any process of activation rapid enough to maintain the full Maxwell-Boltzmann quota of activated molecules and thus to assure a first order course to the reaction.

Chemical abundances in active galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The Sloan Digital Sky Survey (SDSS) has proved to be a powerful resource for understanding the physical properties and chemical composition of star-forming galaxies in the local Universe. The SDSS population of active galactic nuclei (AGNs) remains as of yet less explored in this capacity.
