Thermally Processable, Transparent, Mechanically Tunable and Robust Bioplastics From Wastepaper

Advanced Science, EarlyView.
Unlike conventional inefficient or low‐value wastepaper recycling, a directional transformation strategy is employed to convert whole wastepaper into intact bioplastics with tunable mechanical properties in our work. These bioplastics can be processed into flexible bags or rigid containers and exhibit high transparency, water resistance, repairability,

Improved Drainage of LNFC-reinforced Recycled Pulp and Mechanical Properties of End Papers by the Zeolite- Chitosan Microparticle Drainage Aid System

BioResources, 2023
Good drainage of the pulp suspension is vitally important for stable papermaking. Although the addition of lignocellulosic nanofibers (LNFC) in pulp could highly reinforce the end paper sheets, the application of LNFC could diminished the pulp drainage ...

Influences of the operating variables of acetosolv pulping on pulp properties of oil palm frond fibres

Maderas: Ciencia y Tecnología, 2011
The effect of acetosolv pulping variables viz. pulping time, temperature, catalyst (HCl) and acetic acid on oil palm frond fibres was investigated. The following conditions were found to be optimum to pulp frond fibres: 140 ºC, 0.5% HCl, 75% acetic acid,

Closed‐Loop Radiative Cooling Mulch Upcycled From Agricultural Residues for Efficient Soil Heat–Water Stress Mitigation

Advanced Science, EarlyView.
Conventional passive radiative cooling films rely on costly feedstocks and energy‐intensive fabrication, with poor end‐of‐life compatibility in agriculture. To address this challenge, a sustainable radiative cooling mulch (SRCM) is developed from waste maize leaves via spontaneous hydrogen‐bond self‐assembly.

Biomimetic Self‐Reconfigurable Soft Gripper for Cross‐Scale, Multi‐Particle, and High‐Load Multifunctional Manipulation

Advanced Science, EarlyView.
A fully soft, self‐reconfigurable gripper inspired by rapeseed flowers is monolithically 3D‐printed and electronics‐free, switching between diagonal and parallel finger arrangements. Establishing a self‐reconfigurable grasping paradigm, the gripper enables diverse manipulation tasks, including rotating bulbs, picking fruits, grasping cross‐scale ...

Chemical and Fibre Properties by Lemon Grass in Chemical Pulping for Pulp Industry

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Malaysia has a high rate of depleting forest activities than any other tropical countries in the world. This lead to an increasing of pollution and loss of forest trees include animal to our nature. Lemon grasses as a substitute material from non-wood material had been choose for pulp and papermaking industry.

Molecular Dynamics‐Guided Sterol Engineering of mRNA‐Lipid Nanoparticles Reprograms Biodistribution and Enhances Spleen‐Selective Immunity

Advanced Science, EarlyView.
Sterol engineering enables precise control of mRNA lipid nanoparticles by tuning membrane organization. Replacing cholesterol with bile acid‐derived sterols redirects protein expression from the liver to the spleen. Notably, CA‐20 LNP enhances antigen‐specific immune responses while exhibiting a favorable safety profile, highlighting sterols as a ...

Human Dental Pulp Stem Cell Secretome Restores Ischemic Stroke–Impaired Motor and Cognitive Functions by Reprogramming Redox and Inflammatory Signaling

Advanced Science, EarlyView.
Human dental pulp stem cell secretome emerges as a cell‐free therapeutic strategy for ischemic stroke by reprogramming redox and inflammatory signaling. hDPSC secretome‐derived antioxidant and immunomodulatory factors suppress the TLR4–NOX–ROS–NF‐κB axis, reduce microglial inflammatory responses and apoptosis, and promote neurogenesis, angiogenesis ...

Chemical pulping: the influence of the molecular weight of added xylan on pulp properties [PDF]

, 2013
The aim of this study was to investigate if added beech xylan with low molecule weight (Mw) could penetrate into the fiber wall to a greater extent compared to xylan with high Mw. The high Mw (ca 11000) xylan was degraded using enzymes to obtain xylan with low Mw (ca 1800).

Evaluation of the Effect of Endoglucanase Refining on the Physical and Mechanical Properties of Paper Made from OCC Pulp [PDF]

Iranian Journal of Wood and Paper Industries, 2013
In this study, the effect of enzymatic refining with endoglucanase was investigated on the physical and mechanical properties of OCC pulp. Collected OCC pulps were pre-treated with different endoglucanse dosages (1u, 2u and 3u on o.d.
