In-situ Green Synthesis of Gold Nanoparticles using Unbleached Kraft Pulp

BioResources, 2015
Facile green synthesis of gold nanoparticles (AuNPs) on cellulose fiber was successfully achieved by reducing chloroauric acid (HAuCl4·3H2O) by means of unbleached kraft pulp.

Study of the effects of DES-like mixtures on the properties of unbleached softwood kraft pulp

Results in Chemistry
The scientific community has been drawn to variations of the processes aimed at obtaining cellulosic fibers. Deep eutectic solvents-like mixtures have been shown to be a potential and green replacement for pulping processes where, in addition to ...

Fractionation of Wood Biomass With Thiolactic Acid and Choline Chloride-Based Solvent Into White Lignin for Sustainable Cooling Applications. [PDF]

ChemSusChem
A novel and highly efficient wood biomass fractionation method was developed to produce white lignin, exhibiting the brightest color reported to date. The process yielded white lignin with high yield, excellent visible light reflectance, and elevated infrared emissivity, highlighting its potential as an active material for passive radiative cooling ...

Effect of H2O2 bleaching with ultrasonication on the properties of thermomechanical pulp and unbleached kraft pulp

Ultrasonics Sonochemistry, 2015
Abstract H2O2 was used in the final stage of a multistage bleaching process to increase ISO brightness by 2–3%, because of the poor selectivity and bleachability. However, concerns about the environmental load of the bleaching process have led to the efficient use of oxygen-derived compounds, with a concomitant decrease in the quantity of chlorine ...

Electrochemical Characteristics of Lignin in CTMP for Paper Battery Electrodes. [PDF]

ChemSusChem
Lignin naturally present in papers made of unbleached mechanical pulps is electrochemically active. Here, softwood chemi‐thermomechanical pulp (CTMP) is studied as an active cathode material for application in paper batteries. Proof‐of‐concept measurements are shown, and it is found that softwood CTMP fines exhibit competing oxidative electrochemical ...

Mistletoe- and Mussel-Inspired Fabrication of Hierarchically Structured Protein-Cellulose Scaffolds From Biomolecular Condensates. [PDF]

Adv Mater
Merging materials processing tricks inspired by mussel and mistletoe fiber fabrication, solutions of cationic mussel byssus proteins were mixed with modified anionic nanocrystalline cellulose, producing distinctive core‐shell condensates. Simple processing of condensate suspensions using freeze‐drying produced hierarchically structured porous protein ...

Effect of Electron Beam Irradiation on the Properties of Softwood Unbleached Kraft Pulp

Palpu Chongi Gisul/Journal of Korea Technical Association of the Pulp and Paper Industry, 2015
Electron beam irradiation is also an eco-friendly treatment compared to other physical and chemical treatments. In this study, we attempted to evaluate the possibilities of energy savings by applying electron beam irradiation to the refining process. After softwood unbleached kraft pulp (UKP) was irradiated with electron beams at 50 and 100 kGy, it was

Effects of a poly(hydroxyalkanoate) elastomer and kraft pulp fibres on biocomposite properties and three-dimensional (3D) printability of filaments for fused deposition modelling

Journal of Bioresources and Bioproducts, 2022
Three-dimensional (3D) printing is a useful technique that allows the creation of objects with complex structures by deposition of successive layers of material. These materials are often from fossil origin.
