Scale-up activation of carbon fibres for hydrogen storage [PDF]

, 2010
In a previous study, we investigated, at a laboratory scale, the chemical activation of two different carbon fibres (CF), their porosity characterization, and their optimization for hydrogen storage [1]. In the present work, this study is extended to: (i)

Chemical Activation of Lignocellulosic Precursors and Residues: What Else to Consider?

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.

Activated Carbons Derived from High-Temperature Pyrolysis of Lignocellulosic Biomass

C, 2018
Biomass pyrolysis to produce biofuel and hydrogen yields large amounts of charred byproducts with low commercial value. A study was conducted to evaluate their potential for being converted into higher value activated carbons by a low-cost process.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Preparation of Nitrogen-containing Activated Carbon from Waste Medium Density Fiberboard for Electric Double Layer Capacitor

BioResources, 2015
The waste of medium density fiberboards was carbonized at a temperature of 500 °C. The activated carbons were obtained after 16 h of impregnation and 1 h of activation by KOH at 800 °C with KOH/coke mass ratios of 2.5, 3.0, 3.5, and 4.0.
