Environmental Assessment of Cellulose Pulp Production from Wood Waste using Organosolv Treatment

open access: yesEnvironmental and Climate Technologies
In the upcoming years, the paper industry is expected to rely on containerboard for packaging. Since 2020, containerboard has been made from 80 % recycled fibres. Creating a new supply chain for fibres could help mitigate possible shortages.

From Grave to Cradle: Kombucha Waste for Sustainable Electronics

open access: yesAdvanced Science, EarlyView.
This study introduces a sustainable method to purify kombucha bacterial cellulose (KBC) with sodium bicarbonate and hydrogen peroxide, avoiding harsh chemicals. KBC films are patterned with gold and function as pressure sensors for flatfoot gait detection. At the end‐of‐life, the KBC‐based device biodegrades in soil, leaving environmentally benign gold

Preliminary Investigation on Bamboo Pulping [PDF]

open access: yes, 1964
A preliminary investigation on bamboo pulping by Semi-Keebra process reveals that a higher pulp yield than that obtained by most of the known methods of pulping bamboo can be attained by Semi-Keebra process.* The chemical requirement for pulping is lower

Photocatalytically Activated Cu‐N1S3 Single‐Atom Nanozyme: Enhancing Enzyme Activities and Antibacterial Synergy for Highly Efficient Fruit Preservation

open access: yesAdvanced Science, EarlyView.
This study presents S‐coordinated Cu single‐atom nanozymes (Cu/CNS) fabricated via mild photocatalytic self‐assembly strategy. The nanozyme exhibits exceptional multi‐enzyme activity and near‐perfect antimicrobial efficacy. Incorporated into chitosan‐gelatin film, it enables pH‐responsive, broad‐spectrum fruit preservation, more than doubling the shelf‐

Investigation of the Static Mixer for Improved Heat Transfer to Black Liquors [PDF]

open access: yes, 1974
The objective of this experiment was to determine an improved method by which evaporation of kraft black liquors to the 50 to 65% total solids level could be sufficiently performed in multiple effect evaporators.

A Tangentially Sensitive Tactile Sensor Reveals the Stick‐Slip Mechanism and Enhances Robotic Tactile Sensing

open access: yesAdvanced Science, EarlyView.
An ultralight, multilayer anisotropic tactile sensor—an artificial Pacinian corpuscle—exhibits ultrahigh tangential sensitivity (1022 kPa−1) and spatiotemporal sensing. It discriminates static, sliding, and rolling contacts, detects incipient stick–slip via high‑frequency signatures, and enhances robotic touch (100%/98.18% accuracy for active/passive ...

Efficient Preservation of Perishable Fruits by Erasable Metal‐Organic Frameworks

open access: yesAdvanced Science, EarlyView.
This study presents an erasable Pickering emulsion‐based coating stabilized by metal‐organic frameworks. This washable coating significantly extends fruit shelf life by scavenging ethylene and inhibiting foodborne pathogens, offering a sustainable solution for postharvest.

Experimental TGA device for the determination of cellulose pyrolysis behaviour at elevated pressure [PDF]

open access: yes, 2012
Forestry lignocellulosic biomass is a major renewable energy sources in the world. Carbon generated by Nature through photosynthesis process, could potentially be considered as a neutral energy carrier in term of the greenhouse gas emissions, if it is ...

Ce‐Doped Lignin‐Based Nanozyme with Heat‐Activated Hydrolase Activity

open access: yesAdvanced Science, EarlyView.
A novel Ce‐doped lignin‐based hydrolase nanozyme (Ce‐AL) is synthesized using Ce ions coordinated with aminated industrial lignin. The Ce‐AL effectively hydrolyzes phosphate ester bonds and protein amide bonds, maintain high activity at 100°C, and successfully fights bacteria biofilms.

The Effects of Washing between Hydrogen Peroxide Bleaching Stages on Brightness Reversion of a Spruce High-Yield Pulp [PDF]

open access: yes, 1996
The final brightness of a bleached high-yield pulp paper product is a very important factor in determining the quality of the pulp and the product. If the brightness of this product tends to revert in time, then the quality of the product could be viewed
