The innovative study was carried out to produce nano-cellulose based bioplastic biomaterials for vehicle use coming after bioprocess technology. The data show that nano-cellulose particle size was 20 nm and negligible water absorption was 0.03% in the bioplastic. Moreover, burning test, size and shape characterizations, spray coating dye, energy test and firmness of bioplastic have been explore...

We investigated the autonomous bottom-up fabrication of three-dimensional honeycomb cellulose structures, using Gluconacetobacter xylinus as a bacterial nanoengine, on cellulose honeycomb templates prepared by casting water-in-oil emulsions on glass substrates (Kasai and Kondo, Macromol. Biosci., 4, 17-21, 2004). The template film had a unique molecular orientation state along the honeycomb fra...

Environmental concerns have led to a rapid growing interest in replacing traditional petroleum-based technology with more green alternatives. Cellulose, one of the main components in plants, is a biodegradable and renewable recourse. The use of cellulose fibers, instead of traditional fibers such as glass and carbon, offers a way to make more environmental friendly biocomposites. By replacing t...

In many areas of science and technology, patterned films and surfaces play a key role in engineering and development of advanced materials. Here, we introduce a new generic technique for the fabrication of polysaccharide nano-structures via focused electron beam induced conversion (FEBIC). For the proof of principle, organosoluble trimethylsilyl-cellulose (TMSC) thin films have been deposited b...

Effect of electro migration on crystal structures of platinum nanowire (Nano bridge) during Nano-gap formation is investigated by means of Transmission Electron Microscopy (TEM). Selected area diffraction patterns as well as bright field images are used for this investigation. There were severely recessions in the polycrystalline Nano bridge and crystal structures around the nanogap changed ...

The in-situ nano-crystal-to-crystal transformation (SCCT) synthesis provides a powerful approach for tailoring controllable feature shapes and sizes of nano crystals. In this work, three nitrogen-rich energetic nano-crystals based on 5,5'-azotetrazolate(AZT2-) Cr(III) salts were synthesized by means of SCCT methodology. SEM and TEM analyses show that the energetic nano-crystals feature a compos...

Biodegradation of plant biomass is a slow process in nature, and hydrolysis of cellulose is also widely considered to be a rate-limiting step in the proposed industrial process of converting lignocellulosic materials to biofuels. It is generally known that a team of enzymes including endo- and exocellulases as well as cellobiases are required to act synergistically to hydrolyze cellulose to glu...

The purpose of this study was to develop a new use for microbial cellulose produced by the bacterium, Acetobacter xylinum. There is a potential application of bacterial cellulose to construct a nano-scale laminar flow reactor. Small particles (i.e. enzymes or solid phase reactants) can be embedded in a growing cellulose matrix with geographic specificity. A fluid containing a substrate can then...

In this study, we solely focused on the isolation of nano cellulose from the teak wood by adopting pulping and acid hydrolysis. Top down method is carried out in the extraction of Cellulosic nano fibrils. The removal of non-cellulosic constituents is monitored by FTIR-ATR and UV-Vis DRS Spectroscopic techniques throughout the isolation process. The acidic hydrolysis is applied to extract the na...
