A unique three dimensional (3D) porous structured bacterial cellulose (BC) can act as a supporting material to deposit the nanofillers in order to create advanced BC-based functional nanomaterials for various technological applications. In this study, novel nanocomposites comprised of BC with exfoliated graphite nanoplatelets (xGnP) incorporated into the BC matrix were prepared using a simple particle impregnation strategy to enhance the thermal properties and electrical conductivity of the BC. The flake-shaped xGnP particles were well dispersed and formed a continuous network throughout the BC matrix. The temperature at 10% weight loss, thermal stability and residual ash content of the nanocomposites increased at higher xGnP loadings. The electrical conductivity of the composites increased with increasing xGnP loading (attaining values 0.75 S/cm with the addition of 2 wt.% of xGnP). The enhanced conductive and thermal properties of the BC-xGnP nanocomposites will broaden applications (biosensors, tissue engineering, etc.) of BC and xGnP.

Unlabelled: Bacterial cellulose (BC) is an extracellular polysaccharide produced by bacteria that has wide applications in the food industry, tissue engineering, and battery manufacturing. Genome editing of BC-producing species is expected to optimize BC production and its properties. However, the available technology can target only one gene at a time and requires foreign DNA templates, which may present a regulatory hurdle for genetically modified organisms.

In this study, soybean protein isolate (SPI) / bacterial cellulose (BC) co-assemblies replicate the fibrous network structure in animal fat to stabilize the 3D-printed high internal phase Pickering emulsion (HIPPE) gels with excellent processing characteristics. The SPI/BC co-assemblies, structured through pH shifting treatment, displayed exceptional emulsification and gelation properties. The relevant results indicate that the SPI/BC co-assemblies possess numerous hydrophobic and thiol groups on their surfaces.

Cyclodextrin metal-organic frameworks (CD-MOFs) with infinitely extensible network structures show potential applications in lithium metal batteries. However, the disordered accumulation of CD-MOF particles leads to slow interparticle diffusion of ions, so the CD-MOF composite electrolytes are needed to be developed. In addition, the influences of CD-MOFs structure on the electrochemical performance of the composite electrolytes remains unclear.

The fabrications of circularly polarized luminescent (CPL) material are mainly based on the chemical and physical strategies. Controlled biosynthesis of CPL-active materials is beset with difficulties due to the lack of bioactive luminescent precursors and bio-reactors. Enlighted by microbe-assisted asymmetric biosynthesis, herein, we show the in situ bacterial fermentation of Komagataeibacter sucrofermentants to fabricate a series of bacterial cellulosic biofilms with CPL of green, orange, red, and near-infrared colors.
