Hydrolysis of Cellulose Using an Acidic and Hydrophobic Ionic Liquid and Subsequent Separation of Glucose Aqueous Solution from the Ionic Liquid and 5-(Hydroxymethyl)furfural

, 2016
Cellulose was hydrolyzed using a novel biphasic system consisting of water and an acidic and hydrophobic ionic liquid. The biphasic system enabled a simple separation of the resulting glucose aqueous solution and ionic liquid.

Direct Sequencing of 5‐Methylcytosine and 5‐Hydroxymethylcytosine at Single‐Base Resolution Unravels Their Distinct Roles in Alzheimer's Disease

Advanced Science, EarlyView.
This study introduces two orthogonal sequencing methods, CMD1‐Deaminase sequencing (CD‐seq) and CMD1‐TET bisulfite sequencing (CT‐seq), that enable direct, independent detection of 5mC. Using these approaches together with ACE‐seq or TAB‐seq for 5hmC identification, the study reveals a significant reduction in 5hmC, but not 5mC, in the hippocampus of ...

The Iron–Sulfur Cluster of Bacterioferritin‐Associated Ferredoxin (Bfd): a “Biological Fuse” that Prevents Oxidative Damage to Cells?

Angewandte Chemie, EarlyView.
When cellular iron is low, bacterioferritin (Bfr) releases its stored iron through a reductive process dependent on the [2Fe–2S] ferredoxin Bfd. Why accessing stored iron should depend on an iron‐requiring protein when iron is scarce is unclear. Here, we show that the Bfd [2Fe–2S] cluster is sensitive to oxidative stress, suggesting that it may act as ...

Investigation of the key active intermediate for the synthesis of 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane: Hydrolysis and nitrolysis of 1-acetoxymethyl-3,5,7-trinitro-1,3,5,7-tetraazacyclooctane

Energetic Materials Frontiers, 2020
The problem whether 1-hydroxylmethyl-3,5,7-trinitro-1,3,5,7-tetraazacyclooctane is the key active intermediate for the synthesis of 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX) from urotropine or 3,7-dinitro-1,3,5,7-tetraazabicyclo[3.3.1]nonane ...

Natural and unnatural anthraquinones isolated from the ethanol extract of the roots of Knoxia valerianoides

Acta Pharmaceutica Sinica B, 2012
Eight new 9,10-anthraquinones (1–8) including three acetonide derivatives of 3-hydroxy-2-hydroxymethyl-9,10-anthraquinones (6–8) were isolated from an ethanol extract of the roots of Knoxia valerianoides. On the basis of chemical transformation reactions

Electroplating Carbon Nano‐Onion on Copper for Dendrite‐Free and Anode‐Free Zinc‐Ion Batteries

Advanced Science, EarlyView.
Zinc‐ion batteries are emerging as safe and cost‐effective alternatives to lithium‐ion batteries, but suffer from dendrite formation and unstable anodes. An electroplating approach for preparing a carbon nano‐onion (CNO)‐embedded‐Cu layer on Cu foil is presented, which enables highly reversible zinc plating/stripping (99.89% efficiency over 1400 cycles)
