A Study of the Effects of Ionic Charge and Molecular Weight of Polymers on Wet-Web Strength [PDF]

open access: yes, 1978
Improved machine speeds in the production of paper have increased the number of wet-end breaks due to wet-webs that are unable to withstand the increased stresses at increased rates of production.

Potential drivers of fast growth in Paulownia

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Trees in the genus Paulownia play a crucial role in sustainable forestry, rural economic development, and carbon mitigation due to their rapid growth, exceptional hardwood properties, and prominent carbon sequestration capacity. This review highlights the societal value of Paulownia trees and synthesizes several potential drivers of extraordinarily ...

Effects of Morphological Age and Indole-3-Butyric Acid Concentration on Rooting of Selected Robusta Coffee Varieties

open access: yesCoffee and Cocoa Research Journal
In response to the outbreak of Coffee Wilt Disease (CWD) which wiped out almost 50% of Robusta coffee in Uganda, the National Coffee Research Institute (NaCORI) released 10 varieties (KR1-10) which are resistant to the disease. These varieties are being

Hydrogen Ion Concentration of Sheet Making Water and Its Relationship to the Hygroexpansion of Paper [PDF]

open access: yes, 1967
The hygroexpansivity of paper is of particular importance in the paper industry. As paper dimensions become more critical, the problem of hygroexpansivity in paper necessarily becomes more critical.

On the Origins of Out‐of‐Plane Auxetic Response in Paper

open access: yesphysica status solidi (b), EarlyView.
Paper can be auxetic! Paper can exhibit a range of out‐of‐plane Poisson's ratio (PR) values. Examining handsheets made from hardwood (HW) and softwood (SW) fibers, of a variety of weights (1, 3, or 5 g) and refining degrees (none, R, or R+), showed that the sign and magnitude of PR can be finely controlled by modifying network parameters.

An Evaluation of Never-Dried Pulp at Multiple Freeness Levels [PDF]

open access: yes, 1998
Recycled paper is a viable and economical source of useful wood fiber for paper manufacture. Two of the largest contributors to today\u27s paper waste stream are Mixed-Office Waste (Softwood Kraft Pulp) and Newsprint (Stone Groundwood Pulp).

Investigating the Three‐Dimensional Forming of Microfibrillated Cellulose‐Coated Paperboard With Full and Localised Coatings in Thermoforming, Hydroforming and Deep Drawing

open access: yesPackaging Technology and Science, EarlyView.
The 3D formability of paperboard was examined using full and localised microfibrillated cellulose (MFC) coatings in thermoforming, hydroforming and deep drawing, and the results were linked to bulge‐test strain behaviour. Full‐surface fluidised MFC coatings consistently improved strain capacity and 3D formability, achieving performance comparable to ...

Precipitation of Lignin from Softwood Black Liquor: An Investigation of the Equilibrium and Molecular Properties of Lignin

open access: yesBioResources, 2015
Extracting lignin from black liquor is an attractive option in modern pulp mills as a unit process for a combined biorefinery. The lignin obtained can be utilized as solid fuel or other high-value added products.

The Application of Hydrochar Composite Briquettes for Sustainable Slag Foaming in the Electric Arc Furnace Process

open access: yessteel research international, EarlyView.
Hydrochar‐mill‐scale briquettes with varying C/O molar ratios (0.07–0.90) have been tested at 1650 °C to evaluate their slag foaming performance for electric arc furnace application. All seven briquette recipes developed succeed in promoting slag foaming.
