AB  - Many articles in the literature deal with horseradish peroxidase (HRP) biomineralization,but none pay attention to the isoenzyme composition of commercial HRP or the influence of thecarbohydrate component of the protein molecule on the biomineralization process. To study theimpact of these factors, we performed periodate oxidation of commercial HRP and a purified HRP-Cisoform for biomineralization within ZIF-8. With purified HRP, enzyme@ZIF-8 biocomposites withhigher activity were obtained, while periodate oxidation of the carbohydrate component of bothcommercial HRP and purified HRP-C yields biocomposites with very high activity in acetate bufferthat does not degrade the ZIF-8 structure. Using acetate instead of phosphate buffer can prevent thefalse high activity of HRP@ZIF-8 biocomposites caused by the degradation of ZIF-8 coating. At thesame time, purification and especially oxidation of the carbohydrate component of enzymes prior tobiomineralization lead to significantly improved activity of the biocomposites.

AB  - The durability of enzymes in harsh conditions can be enhanced by immobilization within metal-organic frameworks(MOFs) via a process called biomimetic mineralisation. Zeolitic imidazolate framework-8 (ZIF-8) is widely used as aprotective coating to encapsulate proteins. The formation of nucleation centres and further biocomposite particlegrowth is entirely governed by the pure electrostatic interactions between the protein’s surface and positively chargedZn(II) metal ions. It was previously shown that enhancing these electrostatic interactions by a chemical modificationof surface amino acid residues can lead to a rapid biocomposite formation. However, a chemical modification ofcarbohydrate components by periodate oxidation for glycoproteins can serve as an alternative strategy. In the presentstudy, an industrially important enzyme glucose oxidase (GOx) was selected as a model system. Periodate oxidationof GOx by 2.5 mM sodium periodate increased negative charge on the enzyme molecule. Biomineralizationexperiments with oxidized GOx resulted in higher specific activity, effectiveness factor, and higher thermostability ofthe ZIF-8 biocomposites.

AB  - Metal-organic frameworks (MOFs) are a class of materials well-known for their high degree of crystallinity andultrahigh porosity. Modular synthesis from organic linkers and metal nodes allows for precise control of structure,pore size and chemical functionality of MOFs. Recently, MOFs have been explored for their potential to form novelbiocomposites with proteins by a process termed biomimetic mineralization. These novel MOF biocomposites showgreat promise for application to industrial biocatalysis where strategies for enhancing enzyme stability are ofsignificant interest. The protective capacity and applications of biomimetically mineralized biomacromolecule zeoliticimidazolate framework (ZIF-8) composites are likely dependent on the charge of the biomolecule and the topologyof the mineralized ZIF-8 coating. Herein, we identify conditions to reliably yield the porous periodate oxidizedhorseradish peroxidase@ZIF-8 sodalite topology biocomposite in preference to other more dense phases.

AB  - As a renewable resource, starch is considered to be fully biodegradable and nonpolluting to the environment but the hygroscopicity of starch is the main disadvantage for wider applicability in the production of a polymer-based material. Hydrophobically modified starch prepared using natural-based plasticizers/modifiers in a first step ([−]-diisopropyl D-tartrate [DiPT], ricinoleic acid [RA] and epoxidized soybean oil [ESO]), and maleated polypropylene (MAPP) in a second step contributed to better compatibility, and thus reinforcing of composites. Tailored processing conditions, structural/morphological properties, hydrophobicity, and water-resistance of the modified starch were established. In addition, the Charpy impact and tensile strength of composites, based on poly(ethylene-co-acrylic acid) (EAA) and modified starches, were determined. Increased tensile strength and Young modulus of the composite using starch-modified with DiPT-MAPP, that is, 3 and 83%, respectively, indicated the possible applicability of obtained materials.

AB  - Cavitation erosion of hybrid acrylate composite films with polyhedral
oligosilsesquioxanes (POSS) was investigated in this study. The hybrid films are
made with 1, 3 and 5 wt% of POSS reagents containing: (a) hydroxyl (POSS-M),
(b) both hydroxyl and allyl (POSS-M-A) and (c) methacryloyl groups (POSS-MCl).
Addition of 5 wt% POSS-M-A caused the highest microhardness increase for
49.8%, in comparison to the pure matrix material. Cavitation resistance of hybrid
films, estimated as the time-dependent mass loss, was improved by POSS addition.
POSS-M-A addition (5 wt%) contributed to 94% lower mass loss comparing
to pure Bis-GMA/TEGDMA film. Scanning electron (SEM) and atomic force
microscopy (AFM) showed the lowest surface roughness obtained for composite
with POSS-M-A. The improved hardness and wear resistance of the composite
films indicated that POSS-M-A filler enhanced interfacial adhesion and reinforcing
of the Bis-GMA/TEGDMA matrix.

AB  - A simple one-step microwave-assisted and temperature-controlled hydrothermal synthesis was applied to prepare a nanocrystalline RuO2 dispersion from an aqueous solution of RuCl3 for supercapacitive applications. The obtained RuO2 dispersions were subjected to dynamic light scattering in order to analyze the particle size distribution, whereas morphology and structural properties of the solid phase were investigated by using AFM, SEM, EDX, TEM, and XRD techniques. Ellipsoidally shaped 100-500 nm-sized compact grains, joined into highly ordered prismatic agglomerates, are observed. Two types of grains are observed: more regular ones consisting of spherical, amorphous particles of a few nanometers in size, and irregular ones made of partially crystalline 10-80 nm-sized particles. Consequently, the most dominant structure is 250-nm grains. The particles tend to join tightly across their crystalline domains, which appears responsible for the formation of prismatic shapes of several micrometers. This arraying causes high capacitive activity - specific capacitances of up to 800 Fg(-1) are registered, which negligibly depend on the charging/discharging rate. The synthesized material is of highly accessible internal structure, and is an excellent candidate for both low- and high-power applications.

abstract = "A simple one-step microwave-assisted and temperature-controlled hydrothermal synthesis was applied to prepare a nanocrystalline RuO2 dispersion from an aqueous solution of RuCl3 for supercapacitive applications. The obtained RuO2 dispersions were subjected to dynamic light scattering in order to analyze the particle size distribution, whereas morphology and structural properties of the solid phase were investigated by using AFM, SEM, EDX, TEM, and XRD techniques. Ellipsoidally shaped 100-500 nm-sized compact grains, joined into highly ordered prismatic agglomerates, are observed.
