CHLORINE DIOXIDE BLEACHING OF SODA-ANTHRAQUINONE JUTE PULP TO A VERY HIGH BRIGHTNESS

BioResources, 2010
Bleaching of soda-anthraquinone jute pulp by chlorine dioxide (ClO2) was studied to reach a target brightness of above 88% for the purpose of using less bleaching chemicals. The performance of either chlorine dioxide or peroxide in the final bleaching to

Kinetics of oxidation of a hemicellulose model compound by chlorine dioxide in bleaching

BioResources, 2018
Kinetics of the oxidation of D-xylose, a hemicellulose model compound, by chlorine dioxide was studied under simulated bleaching conditions. The final reaction product, chloroacetic acid, which is a type of adsorbable organic halogen (AOX), was detected by gas chromatography-mass spectrometer (GC-MS). The kinetic equation was expressed as dW/dt = 2.36e-

Structure and Dynamics of Imidazolium in an Ionic Liquid‐PEGDA Iongel via IR, 2D‐IR, and NMR Spectroscopy

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
Linear and nonlinear vibrational spectroscopies detect tight and loose complexes between imidazolium cations and poly(ethyleneoxide) chains in an iongel. Fourier transform infrared absorption spectroscopy, ultrafast two‐dimensional infrared spectroscopy, nuclear magnetic resonance spectroscopy, and density functional theory calculations show that, in ...

Modification of chlorine dioxide bleaching of Gmelina arborea (gamar) pulp

Bangladesh Journal of Scientific and Industrial Research, 2017
Elemental Chlorine Free (ECF) pulp bleaching is now the dominant pulp bleaching process in globally. In most bleachery, chlorine dioxide is over-consumed. About two thirds of the chlorine dioxide is wasted in useless side reactions. In the study, kraft pulp from Gmelina arborea (gamar wood) was bleached by ECF bleaching in modified sequences.

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

Advanced Science, Volume 13, Issue 19, 2 April 2026.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

Kraft pulping and ECF bleaching of Eucalyptus globulus pretreated by the white-rot fungus Ceriporiopsis subvermispora - doi: 10.4025/actascitechnol.v34i3.12410

Acta Scientiarum: Technology, 2012
Eucalyptus globulus wood chips were decayed by the lignin-degrading fungus Ceriporiopsis subvermispora as a pretreatment step before kraft pulping. Weight and component losses of wood after the biotreatment were the following: weight (5%), glucans (1.5%),
