Biopolymers and their composites have been extensively investigated in recent years for multiple applications, especially in environmental, medical, and pharmaceutical fields. Bacterial cellulose (BC) has emerged as a novel biomaterial owing to its nontoxic, high-liquid absorbing and holding capacity, drug-carrying ability, and pollutant absorbing features. Additionally, its web-shaped three-dimensional (3D) structure and hydrogen bonding sites have incited a combination of various nanoparticles, polymers, and other materials with BC in the form of composites. Such BC-based composites have been developed through in-situ, ex-situ, and solution casting methods for targeted applications, such as air and water filters, controlled drug delivery systems, wound dressing materials, and tissue regeneration. This review details the production and development of BCbased composites with different materials and by various methods. It further describes various applications of BC-based composites in the environmental and pharmaceutical sectors, with specific examples from the recent literature. This review could potentially appeal a wide readership in these two emerging fields, where novel and advanced materials for different applications have been developed on a regular basis using BC as the base material.

Assembly Strategy

Large-scale synthesis and assembly of meso-, micro- and nanostructured building blocks with the desired orientations are of great interest for the next-generation nanoarchitecture design. On the consideration that the traditional synthetic methodologies for nanostructures often produce tangled nanounits, how to align the nanounits into the ordered orientation at high production yield is a great challenge to current methods. The present review describes a facile and controllable way to grow and assemble the 3D hollow nanoarchitectures, with the utilization of the synergic effects of hollowing process from the self-produced templates and the highly anisotropic growth of nanounits of the target materials in one-pot reaction. In this process, the building block nanounits spontaneously in-situ form owing to their highly anisotropic internal structure, while the self-produced templates act as the supporter and growth-direction guidance for the in-situ formed nanounits. Therefore, the whole assembly process is simple, controllable and without the complicated manipulations. Herein, in the light of the different kinds of self-produced templates involved in the assembly process, recent developments based on the new synergic-assembly strategy are reviewed according to the classifications: (1) self-produced gas bubble template strategy; (2) self-produced homogeneous solid template strategy; (3) self-produced heterogeneous solid template strategy. Notably, the synergic-assembly methodology described in this review provides a newly essential way to construct and assemble nanoarchitectures facilely and controllably, and is also a crucial step for the next-generation of nanoarchitecture design in the near future. In conclusion, the challenges and prospects for the future are discussed.

Mode Of Coordination

Two alkaline-earth coordination compounds, [Ba(C8H4N4O2)(H2O)4] n , (I), and [Sr(C8H4N4O2)(H2O)3] n , (II), from the one-pot hydrolysis transformation of benzoyl chloride and the in situ self-assembled [2 + 3] cycloaddition of nitrile are presented. These coordination compounds are prepared by reacting 4-cyanobenzoyl chloride with divalent alkaline-earth salts (BaCl2 and SrCl2) in aqueous solution under hydrothermal conditions. The mononuclear coordination compounds (I) and (II) show the same mode of coordination of the organic ligands. The cohesion of the crystalline structures is provided by hydrogen bonds and π-stacking interactions, thus forming three-dimensional supramolecular networks. The two compounds have a three-dimensional (3,6)-connected topology, and the structural differences between them is in the number of water molecules around the alkaline earth metals. Having the same emission frequencies, the compounds exhibit photoluminescence properties with a downward absorption value from (I) to (II).
