Abstract Cellulose-based materials represent a renewable, biodegradable, and environmentally friendly alternative to plastic from fossil resources. Nanopaper is strong lightweight material formed cellulose nanofibrils (CNFs). Paper nanopaper have been considered as excellent alternatives plastics for use in agriculture packaging applications. However, common both paper their hydrophilic character, consequently, poor water-resistance properties. ORMOCER®s are class of inorganic–organic...
The aim of this work is to develop barrier coatings by using an atmospheric pressure dielectric discharge (DBD). For purpose the plasma polymers obtained from a hybrid organic–inorganic precursor compound as well purely organic were compared. physical properties determined scanning electron microscopy and probe analysis profilometry determining their oxygen transmission rates. chemical structure was revealed ATR-FTIR 13C- 29Si-CP/MAS solid-state nuclear magnetic resonance measurements. It...
The construction and performance of a novel enzyme based optical sensor for in situ continuous monitoring glucose biotechnological production processes is presented. Sensitive coatings are formed from inorganic–organic hybrid polymers (ORMOCER®sORMOCER®: Trademark Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e. V. Germany.) combined with flurophore (ruthenium complex) an enzyme, applied to lenses, declad polymer fibre (POF) clad silica (PCS). oxidase, catalyzes oxidization...
The use of primary amino groups as receptors to detect CO2 is promising because their ability perform reversible acid-base-reactions. In contrast other sensitive materials using this effect, evaluable signals can be obtained even at ambient temperature. effect discussed for most the previously used sensing layers formation bicarbonate species, which needs H2O well an increased and work function readout appears dominated by another reaction, carbamate, does not require any water presence and,...
Membrane distillation is a thermal separation technique using microporous hydrophobic membrane. One of the concerns with respect to industrialization development novel membranes. In this paper, commercially available hydrophilic polyethersulfone membrane suitable structure for was modified coatings ORMOCER® technology obtain that can be applied in distillation. The surface modification performed selection different components, concentrations, and application methods. resulting membranes have...
Kinetic parameters were obtained for glucoamylase catalysed hydrolysis of substrates an alpha-(1,4)-maltooligosaccharide series and a p-nitro-phenyl-alpha-maltooligosaccharide series. p-Nitrophenyl chain length 11 17 synthesized in 97% 95% purity, respectively, to test the significance binding at remote subsites. The affinities subsites > 4 are demonstrated be insignificant. subsite contributions D-glucopyranosyl p-nitrophenyl residues calculated.
We describe the application of inorganic organic hybrid materials (ORMOCERs) as optical fiber coatings for use in Fiber Bragg Grating sensors and high power transmission fibers. The are UV curable, enable a single layer thickness about 50 μm show peak temperature stability >300 °C. Regarding protection have been investigated using tensile strength measurements before after load. Best maintain 68 N (125 fiber) with Weibull parameter 182 cycling up to 300 For first time low refractive index...
