We proposed in a previous paper a unique form of j3-glucan association, nematic ordered cellulose (NOC) that is molecularly ordered, yet non-crystalline. NOC has unique characteristics; in particular, its surface properties provide with a function of tracks or scaffolds for regulated movements and fiber-production or Acetobacter xylinum [Kondo et al. 2002. Proc. Natl. Acad. Sci. USA 99: 14008-1...

Traditionally, polymers and macromolecular components used in the foam industry are mostly derived from petroleum. The current transition to a bio-economy creates demand for the use of more renewable feedstocks. Soybean oil is a vegetable oil, composed mainly of triglycerides, that is suitable material for foam production. In this study, acrylated epoxidized soybean oil and variable amounts of ...

Most of the artificial superhydrophobic surfaces that have been fabricated to date are not biodegradable, renewable, or mechanically flexible and are often expensive, which limits their potential applications. In contrast, cellulose, a biodegradable, renewable, flexible, inexpensive, biopolymer which is abundantly present in nature, satisfies all the above requirements, but it is not superhydro...

Lyotropic liquid crystals based on mixtures of cellulose tricarbanilates (urethanes) generated stronger selective reflection in the visible range after an increase in concentration of approximately 9 wt.-% above the concentrations described by Miiller, Zentel, and Keller in "Solid Opalescent Films Originating from Urethanes of Cellulose".[2] The cellulose urethanes used were of a lower molecula...

Hydroxygallium phthalocyanine (HOGaPc) and cellulose (from a trimethylsilyl derivative) have been used as native elements for the preparation of a novel family of hybrid films. By spin-coating, both components allow the building of films with different configurations on various substrates in a controlled way. The particularities of these hybrid films have been characterized by a range of techni...

This study demonstrates the feasibility of integrating the production of nano-fibrillated cellulose (NFC), a potentially highly valuable biomaterial, with sugar/biofuel (ethanol) from wood fibers. Commercial cellulase enzymes were used to fractionate the less recalcitrant amorphous cellulose from a bleached Kraft eucalyptus pulp, resulting in a highly crystalline and recalcitrant cellulose (RC)...

Antimicrobial agents such as essential oils have wide applications, and their use in edible films has been reported to enhance the shelf life of meat and its products. The present study aimed to assess the effects of chitosan films on the inhibition of Staphylococcus aureus  in hamburger samples in storage conditions (temperature: 4±1°C). The prepared films contained 0.8% nanoemulsion ...

Recently, a cellulose-based composite material with a thin ZnO nanolayer-namely, ZnO nanocoated cellulose film (ZONCE)-was fabricated to increase its piezoelectric charge constant. However, the fabrication method has limitations to its application in mass production. In this paper, a hydrothermal synthesis method suitable for the mass production of ZONCE (HZONCE) is proposed. A simple hydrother...

BACKGROUND AND THE PURPOSE OF THE STUDY Multiparticulates by powder layering process have advantages of the uniform distribution of the binder solution, easy-to-clean pan and the possibility of applying the successive functional film coating using the same equipment. This study relates to a multiparticulate formulation comprising pellets with a multilayer of pectin-ethyl cellulose on non pareil...

Cellulose-based triboelectric nanogenerators (TENGs) can provide power for various monitoring devices and are environmentally friendly sustainable. Chemical functional modification is a common method to improve the electrical output performance of cellulose-based TENGs. In this work, an high-performance nanogenerator based on polydopamine/cellulose nanofibril (PDA/CNF) composite membrane fluori...
