Recent Advances in the Fabrication of Structural Nanocellulose-Loaded Functionalized Biochar-Based Biopolymeric Nanocomposites for Industrial Wastewater Treatment by Continuous Adsorption With Modeling: A Cutting-Edge Review. [PDF]
Glob ChallThis study focused on the advanced fabrication and application of agro‐waste biomass/natural lignocellulosic fiber‐derived structural CNC‐FBC‐based multifunctional biopolymeric nanoadsorbents in industrial wastewater treatment technology. These CNC‐FBC‐based biopolymeric nanosorbents would be a sustainable alternative to fossil‐based, hazardous ones ...

Evaluation of Metal Nanoparticles Using ICP‐OES in Hairs of Patients With Frontal Fibrosing Alopecia and Comparison With Control Group [PDF]
J Cosmet DermatolABSTRACT Background Frontal fibrosing alopecia (FFA) is an increasingly prevalent scarring alopecia potentially linked to environmental factors such as nanoparticles (NPs) in skincare and sunscreens. Objectives This case–control study aimed to quantify titanium, zinc, aluminum, and iron concentrations in hair shafts of FFA patients versus controls ...

Kinetics of AOX Formation in Chlorine Dioxide Bleaching of Bagasse Pulp
BioResources, 2014 In this paper, a kinetic model of the first chlorine dioxide bleaching stage (D0) in an elemental chlorine-free (ECF) bleaching sequence is presented for bagasse pulps. The model is based on the rate of adsorbable organic halogen (AOX) formation.

BLEACHING EUCALYPTUS PULPS WITH SHORT SEQUENCES
Ciência Florestal, 2011 Eucalyptus spp kraft pulp, due to its high content of hexenuronic acids, is quite easy to bleach. Therefore, investigations have been made attempting to decrease the number of stages in the bleaching process in order to minimize capital costs. This study
