Physical properties of isolated cellulose fiber from jute and banana fiber through kraft pulping: Potential applications in packaging and regenerated fibers

SPE Polymers
Cellulose, a naturally abundant biopolymer, holds great potential as a sustainable alternative to synthetic fibers. However, the limited understanding and awareness surrounding cellulose utilization, particularly from agricultural origins, have impeded ...

Bionic Solar‐Powered Heavy Metal Trap for Eco‐Friendly Sludge Drying and Simultaneous Electricity Generation

Advanced Science, EarlyView.
Herein, we propose a solar‐powered heavy metal trap (SPHT) for sludge disposal. The indoor experiments demonstrated that the sludge water content decreased from 90 % to 31 %, coupled with a decrease in heavy metal content to 6 % at most. Furthermore, the designed SPHT generated an initial potential of 0.10 V, and monitoring this hydrovoltaic potential ...

Optimizing Delivery Characteristics of Curcumin as a Model Drug via Tailoring Mean Diameter Ranges of Cellulose Beads

International Journal of Polymer Science, 2017
Spherical cellulose beads with tailored mean diameter between micrometer (20–80 μm) and nanometer (40–200 nm) ranges were fabricated from regenerated cellulose of paper wastes via water-in-oil (W/O) microemulsion and nanoprecipitation processes ...

Activation of dissolving celluloses pulp for viscose and cellulose ether production

, 2016
Mercerisation of cellulose by alkali treatment is the most common procedure used to activate natural cellulose fibres into many commercial cellulosic materials. During mercerisation, the NaOH solution enters the cellulose fibres, transforming them into a

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,

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.

Structure and applications of cellulose regenerated from zinc -cellulose complexes

, 1999
Aqueous zinc chloride solutions dissolve cellulose only when concentrations of zinc chloride are above 64% (w/w). However, studies showed that cellulose solutions with zinc chloride concentration above 64% (w/w) could be slowly diluted with water at an ...

Regenerated cellulose/epoxidized natural rubber blend film

, 2013
Regenerated cellulose/epoxidized natural rubber (ENR-50) blended films were prepared using an environmentally friendly ionic liquid, 1-butyl-3-methylimidazolium chloride (BMIMCl). The films were obtained by casting solution method.

Microblasting Wound Dressings Mechanically Disrupt Polymicrobial Biofilms to Enhance Healing in Treatment‐Resistant Wounds

Advanced Science, EarlyView.
Treatment‐resistant wounds caused by polymicrobial biofilms are refractory to conventional therapies due to the dense extracellular matrices. We developed μBLAST, a microblasting wound dressing that combines MnO2‐doped biosilica and a H2O2‐releasing mesh to generate localized oxygen microbubbles that mechanically disrupt biofilms.
