“…FTIR spectra of BC and aminoalkyl‐grafted BC membranes are shown in Figure . All the membranes showed typical absorption peaks of cellulose, at 3343 and 2,895 cm −1 , corresponding to stretching vibrations of ─OH and ─CH 2 ─ groups, respectively (He et al, ; Yue et al, ). Moreover, the adsorption between 1,160 and 1,055 cm −1 was associated with C─O─C pyranose ring skeletal vibration (He et al, ).…”

Bacterial cellulose (BC) membranes display special properties and structures, thus attracting much attention in application in the biomedical areas, for example, as implants for bone or cartilage tissue engineering, as substitutes for skin repairing, and as supports for controlled drug delivery. However, native BC lacks the activity to inhibit bacteria growth on its surface, which limits its applications in biomedical fields. There have been reports on chemical modification of BC membranes to endow them with antimicrobial properties needed for some special biomedical applications. In the present study, aminoalkyl‐grafted BC membranes were prepared by alkoxysilane polycondensation using 3‐aminopropyltriethoxysilane (APTES). The characterization for morphology and chemical composition showed that BC membranes were successfully grafted with aminoalkylsilane groups through covalent bonding. The surface morphology and roughness of the membranes changed after chemical grafting. Furthermore, after grafting with APTES, the membranes got less hydrophilic than native BC. The aminoalkyl‐grafted BC membranes showed strong antibacterial properties against Staphylococcus aureus and Escherichia coli and moreover, they were nontoxic to normal human dermal fibroblasts. These results indicate that aminoalkyl‐grafted BC membranes are potential to be used for biomedical applications.

“…Recent results focus on applications in the area of packaging [149,150], water absorption [151] and supercapacitors [152,153], as well as optical devices [154][155][156][157][158][159][160]. In such applications, either BNC itself is reinforced by additives [161][162][163][164] or BNC serves as the reinforcing material, e.g., for synthetic polymers [165,166]. Another aim of current research is the enhancement of BNC properties to get softer and more flexible materials [167].…”

Nanocelluloses are natural materials with at least one dimension in the nano-scale. They combine important cellulose properties with the features of nanomaterials and open new horizons for materials science and its applications. The field of nanocellulose materials is subdivided into three domains: biotechnologically produced bacterial nanocellulose hydrogels, mechanically delaminated cellulose nanofibers, and hydrolytically extracted cellulose nanocrystals. This review article describes today's state regarding the production, structural details, physicochemical properties, and innovative applications of these nanocelluloses. Promising technical applications including gels/foams, thickeners/stabilizers as well as reinforcing agents have been proposed and research from last five years indicates new potential for groundbreaking innovations in the areas of cosmetic products, wound dressings, drug carriers, medical implants, tissue engineering, food and composites. The current state of worldwide commercialization and the challenge of reducing nanocellulose production costs are also discussed.

“…Lignocellulosic biomass is a domestic bioenergy source, abundantly available in high quantity throughout Europe, and is considered to be the most promising natural source for conversion to ethanol for biofuel and biochemical production, energy conversion and energy storage. Carbon materials obtained from renewable resources [1], utilized in supercapacitors, and functionalized cellulose polymer systems incorporated in lithium-ion batteries [2,3] or fuel and biocells [4], enable the efficient electrochemical energy storage. Recently, the use of renewable resources as electrolytes in solar cells for energy conversion was investigated on [5,6].…”

This study focuses on the mechanocatalytical process combining dilute acid pretreatment and mechanical processing driven by ball milling. Milled and hydrolyzed barley straw samples are subject to reducing sugar analysis by DNS assay and capillary electrophoresis. Optimization of the saccharification conditions was carried out with two different sulfuric acid concentrations, 0.5 mol kg -1 and 1.0 mol kg -1 , and compared. A significant yield of total reducing sugar (53.4 %) was obtained from barley straw impregnated with sulfuric acid (1.0 mol kg -1 ) after milling for only 20 min. Glucose and xylose concentrations accounted for 3.5 % and 11.3 %, respectively. Strikingly, the present study indicates a significant impact of the internal milling vessel temperature in the mechanocatalytical conversion process of barley straw in addition to the mechanical parameters and the catalyst concentration.
