This study aimed to evaluate the effect of size press coating on two types recycled papers using different nanofibrillated cellulose (NFC) and cationic starch (CS) physical mechanical properties. Wheat straw was used as a source, NFC obtained through oxidative enzymatic pretreatments. Recycled fluting coreboard were coated with starch/NFC blends at various concentrations (0.5%, 1%, 2%, 3%, 4%) ...

Monoclonal antibody against light chains of human cardiac myosin (MLC) was labelled with horseradish peroxidase. The conjugation was performed by two different methods with glutaraldehyde and periodate respectively. The binding activities of the conjugates were tested by enzyme linked immunosorbent assay (ELISA) on the microtitration plates with immobilized MLC (1-1000 ng per well). A compariso...

This paper describes a mechanism of coupling periodate-oxidized nucleosides to proteins. Each of the dialdehyde groups of a periodate-oxidized nucleoside is shown to couple to lysine residues on different protein molecules through Schiff bases, thereby cross-linking different protein molecules, forming a polymer. This is in contrast to the previous model in which nucleosides were suggested to c...

The trans-diequatorial 3,4-diol of 2,5-di-O-benzyl-D-chiro-inositol cleaved selectively with the periodate ion in the presence of the trans-diaxial 1,6-diol to give a dialdehyde (dialdose) from which 3,6-di-O-benzyl-D-manno-tetrahydroxyazepane (1) was made. The trans-diaxial 1,6-diol of 3,4-di-O-allyl-2,5-di-O-benzyl-D-chiro-inositol was not cleaved satisfactorily by periodate, but replacement ...

The progress of the research work of the author and his colleagues on the field of CL-emission generated by pyrogallol oxidation and further application for the direct determination of periodate and indirect or direct determination of other compounds through flow-injection manifold/CL-detection set up is described. The instrumentation used for these studies was a simple flow-injection manifold ...

13C nuclear magnetic resonance, paramagnetic resonance, and ultraviolet spectroscopy and highresolution gel permeation chromatography were used to investigate the process of periodate oxidation of carboxymethyl cellulose and the structure and molecular weight characteristics of its oxidised forms produced under different conditions. It was shown that, in solution and in the solid state, aldehyd...

The crystal structure of the room-temperature ferroelectric phase of pyridinium periodate [C6H5NH]+[I04]has been determined by X-ray diffraction as orthorhombic, space group Cmc2i with a = 8.347(2), b = 7.270(2), c = 12.732(3) A and Z = 4. It was refined to/?l =0.0281 wR2 = 0.0762 for 389 absorption-corrected reflections. The structure comprises isolated I0 4 tetrahedra linked together by disor...

The photoactivated periodate (UV/IO4−) process is used to investigate the degradation of acid orange 10 (AO10) dye. photodecomposition ions produces highly reactive radicals (i.e., •OH, IO3•, and IO4•) that accelerate dye degradation. Increasing initial concentration 3 mM enhances removal rate, but over periodate, rate slows down. On contrary, increasing concentrations reduces performance. pH m...
