The aim of the study was to characterize and compare films made cellulose nanocrystals (CNC), nano-fibrils (CNF), bacterial nanocellulose (BNC) in combination with chitosan alginate terms applicability for potential food packaging applications. In total, 25 different formulations were evaluated, seven biopolymer best mechanical performance (tensile strength, strain)—alginate, 5% CNC, chitosan, 3% BNC without glycerol, CNF glycerol—were selected investigated regarding morphology (SEM),...
The valorization study of the largely available corn stover waste biomass after pretreatment with deep eutectic solvent (DES) for biomethane production in one-liter glass bioreactors by anaerobic digestion 21 days was presented. Ammonium thiocyanate and urea pretreatments under different conditions terms components ratio temperature were examined on biomass. lignocellulose characterized detail its chemistry morphology to determine effect natural biocomposite. Furthermore, implications...
The development of sensitive, selective, and reliable gaseous hydrogen peroxide (H2O2) sensors operating at room temperature still represents a remaining challenge. In this work, we have investigated combined the advantageous properties two-dimensional Ti3C2Tx MXene material that exhibits large specific surface area high activity, with favorable conducting stabilizing chitosan. MXene-chitosan membrane was deposited on ferrocyanide-modified screen-printed working carbon electrode, followed by...
Cellulose nanofibrils are one of the keystone materials for sustainable future, yet their poor water repellency hinders push into industrial applications. Due to complexity and economical outcome and/or processing toxicity existing hydrophobization methods, nanocellulose loses against its antagonist plastic in medical food industries. Herein, we demonstrate first time "one-side selective water-repellency activation" membranes by means mild N
Synthesis of substituted anilines upon nucleophilic addition secondary amines to cyclohexanone derivatives followed by aromatization the enamine employing a combination Ir‐polypyridine complex as photoredox catalyst and cobaloxime H2‐evolution was developed recently Leonori et al. In this work, we replace homogeneous heterogeneous mesoporous graphitic carbon nitride (mpg‐CN) that is free rare elements. Substituted aromatic amine H2 are formed simultaneously. Combination X‐Ray spectroscopies...
Cellulose nanomaterials, namely cellulose nanocrystals (CNCs) and nanofibrils (CNFs), present a class of multipurpose, renewable, biodegradable, nontoxic materials, paving the way into future biobased materials. The abundance hydroxyl groups on surface allows modification materials properties according to application; however, fully exploit their potential, better compatibility molecular level with hydrophobic matrixes has be explored beyond lab scale. One main missing pieces in...
Cellulose nanocrystals (CNCs) were acetylated to the various parametrised degrees of substitution (DS), determined through attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) and incorporated into alginate (ALG) chitosan (CH) film-forming solutions. An investigation morphology with scanning electron microscopy (SEM) revealed increased chemical compatibility CH matrix after acetylation, producing a smooth surface layer, while ALG mixed better pristine CNCs. The...
A 70% ethanol(aq) extract of the rhizome bark invasive alien plant species Japanese knotweed (JKRB) with potent (in range vitamin C) and stable antioxidant activity was incorporated in 1% w/v into a chitosan biofoil, which then characterized on lab-scale. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay confirmed JKRB biofoil upon contact food simulants A, B, C, D1 (measured half-maximal inhibitory concentrations—IC50) supported Folin–Ciocalteu result. migration marker, (−)-epicatechin, all...

The article discusses the production of platform chemicals from various biological sources, including glycerol, lignin, cellulose, bio-oils, and sea products. It presents results catalytic downstream processes involved in conversion these biomass-derived feedstocks. experimental approaches are complemented by numerical descriptions, ranging density functional theory (DFT) calculations to kinetic modellingof data. This multi-scale modelling approach helps understand underlying mechanisms...
A highly effective ultrafast chemical modification of chitosan/cellulose nanocrystals composite film surface is presented in the present research. Added value properties were achieved by use a few second’s treatment with RF-generated low-temperature fluorocarbon plasma. Drastic increase water-repelling character completely natural-based biocomposite foil observed, contact angle reaching up to 121 . Surface fluorination occurred through formation irreversible fluorine-related bonds (CFCF2,...
Abstract In this research study, the impact of feedstock to inoculum ( F / I ) amount ratio in dry anaerobic digestion (DAD) Hura crepitans leaves was evaluated. Measured biogas volumes, as well chemical kinetic predictions for exponential, logistic and Gompertz model, depicting agreement simulations over time, were also determined. From equivalents 2, 4 6 at 22 % packed total solids, which considered analysis test procedure, DAD digester with number most promising terms biogas’ production...
