The novel incorporation of lignin-based systems for the preparation of antimicrobial cement composites.

This paper, for the first time, presents a potential application of titanium(IV) oxide and silicon(IV) oxide combined with lignin through a solvent-free mechanical process as admixtures for cement composites. The designed TiO-SiO (1:1 wt./wt.

Evaluation of MO/fucoidan hybrid system and their application in lipase immobilization process.

In this work, new MO/fucoidan hybrid systems were fabricated and applied in lipase immobilization. Magnesium (MgO) and zirconium (ZrO) oxides were used as MO inorganic matrices. In the first step, the proposed oxides were functionalized with fucoidan from Fucus vesiculosus (Fuc).

Catalytic and Physicochemical Evaluation of a TiO/ZnO/Laccase Biocatalytic System: Application in the Decolorization of and Dyes.

A TiO/ZnO oxide system was proposed as a support for the immobilization of laccase from (LTV). The obtained TiO/ZnO/LTV biocatalytic system was then applied in the decolorization/degradation of C.I.

Physicochemical and catalytic properties of acylase I from aspergillus melleus immobilized on amino- and carbonyl-grafted stöber silica.

Acylase I from Aspergillus melleus was immobilized on supports consisting of unmodified and modified silica. Modification was performed using 3-aminopropyltriethoxysilane (APTES) and glutaraldehyde (GA). The effectiveness of immobilization was investigated using the standard Bradford method in addition to a number of physicochemical techniques, including spectroscopic methods (FTIR, Si and C CP MAS NMR), porous structure and elemental analysis, and zeta potential measurement.

Candida antarctica Lipase B Immobilized onto Chitin Conjugated with POSS Compounds: Useful Tool for Rapeseed Oil Conversion.

A new method is proposed for the production of a novel chitin-polyhedral oligomeric silsesquioxanes (POSS) enzyme support. Analysis by such techniques as X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy confirmed the effective functionalization of the chitin surface. The resulting hybrid carriers were used in the process of immobilization of the lipase type b from (CALB).

Chitin-lignin material as a novel matrix for enzyme immobilization.

Innovative materials were made via the combination of chitin and lignin, and the immobilization of lipase from Aspergillus niger. Analysis by techniques including FTIR, XPS and 13C CP MAS NMR confirmed the effective immobilization of the enzyme on the surface of the composite support. The electrokinetic properties of the resulting systems were also determined.

Zinc Oxide-From Synthesis to Application: A Review.

Zinc oxide can be called a multifunctional material thanks to its unique physical and chemical properties. The first part of this paper presents the most important methods of preparation of ZnO divided into metallurgical and chemical methods. The mechanochemical process, controlled precipitation, sol-gel method, solvothermal and hydrothermal method, method using emulsion and microemulsion enviroment and other methods of obtaining zinc oxide were classified as chemical methods.
