IMPROVEMENT OF MECHANICAL PROPERTIES OF WOOD AT THE ACCOUNT OF THEIR ADHESIVE

High-quality solid wood of deciduous and coniferous species in Ukraine is becoming less and less every year. Therefore it is necessary to use that wood which is available. Various methods and techniques are used to improve the mechanical properties of wood. One of them is gluing wood boards of different thickness. In this article we present the following studies taking into account the actual work of the material.
 The method of researches of glued wood of different breeds by axial compression along fibers by short-term loading at standard humidity (by increase of displacements) is given. Complete deformation diagrams “stress σc - deformations uc” are constructed and the main parameters are established: maximum disturbances, critical deformations, initial modulus of elasticity. The strength of glued wood increases in comparison with the indicators of continuous humidity of 12% at the age of 60 by 13-25%; critical deformations slightly increase or decrease in one direction or another; the initial modulus of elasticity increases by 13–31%.
 This improvement is due to the ingress of glue into the body of wood, ie due to gluing is the modification of wood and the formation of composite material. The strength of such a composition is directly affected by the thickness of the board. The smaller the thickness of the board, the stronger the product.
 It is established that the deformation diagrams of glued wood have two branches: ascending and descending. That is, the work of such composite materials is observed, both in the subcritical stage and in the supercritical stage. Therefore, the samples have a certain residual strength after passing the maximum stress values.
 It has been established that gluing wood increases the strength and initial modulus of elasticity of the composite material and depends on the thickness of the board.

Hybrid composite materials generated via growth of carbon nanotubes in expanded graphite pores using a microwave technique

Herein we demonstrate a facile in-situ synthesis method by selection of expanded graphite as a matrix growth microreactor, nickel nitrate (Ni(NO3)2) as a growth catalyst and naphthalene as a carbon source, assisted by a conventional household microwave oven. Affection parameters related to control of the growth process, such as the microwave heating time, catalyst concentration and carbon source concentration. The optimized experimental conditions that exhibit excellent microstructure were: a carbon source concentration of 20.0 mg/ml, a catalyst concentration of 10.0 mg/ml and a microwave reaction time of 30 s. The microstructure of the synthesized composites was investigated and a solid-gas growth mechanism with this carbon source precursor is proposed. The micro morphology, formed CNT structure and resistivity of the composites are fully characterized and analyzed by thermal field emission high-resolution scanning electron microscopy (FESEM), confocal laser Raman spectrometer (Raman) and a four-point probe resistivity meter. All characterization data show a uniform CNT diameter distribution of approximately 30.0 nm with a low resistivity of the composites (1.12 × 10−5 Ω·m), indicating uniform hybrid composite material formation with novel physical properties.

Применение композиционных материалов с магниевой матрицей для подшипников скольжения

Technology for the formation of composite materials with a magnesium matrix and a filler based on lead alloys has been proposed, which makes it possible to increase the tribotechnical properties of plain bearings. According to the proposed technology, a porous magnesium matrix with open porosity is obtained by filtration of a magnesium melt through water-soluble granules, which, after solidification of the melt, are leached into a solution of acetic acid. To obtain a composite casting, a porous magnesium matrix is impregnated with lead or lead alloys. The conducted studies of the formation processes of a composite material with a magnesium matrix and babbit filler showed that the proposed technology makes it possible to obtain composite materials with satisfactory filling of porous magnesium with babbit without discontinuities and visible defects. Filling temperature was 500 – 550 °С and preliminary heating temperature of porous magnesium 200 – 350 °С. Properties of the obtained composite with a magnesium matrix and Babbitt filler showed that the material has a lower, almost 2 times, density, higher thermal conductivity and better performance properties than lead-based alloys.

Obtaining Biocompatible Porous Composite Material Based on Zinc-Modified Hydroxyapatite and Lactide-Glycolide Copolymer

The development of surgery in the field of bone tissue reconstruction provides a stable demand for new materials for implants. Of particular interest are materials based on hydroxyapatite, which are close in chemical composition to the elemental composition and structure of bone and have similar biologically active properties. In this work, the regularities of the formation of new composite materials based on a zinc-modified hydroxyapatite framework coated with a copolymer of lactide and glycolide were revealed for the first time. The aim of this work was to obtain porous composite materials based on zinc-modified hydroxyapatite and a copolymer of lactide and glycolide with properties suitable for use as a material for bone implants. The phase and elemental composition of the composites was studied by infrared spectroscopy, X-ray diffraction, and X-ray spectral microanalysis. Regularities have been established between the surface properties and the composition of materials, as well as their biocompatibility, determined using monocytes isolated from human peripheral blood. The antibacterial activity of the materials against gram-positive and gram-negative bacteria was determined.

Roadmap of Effects of Biowaste-Synthesized Carbon Nanomaterials on Carbon Nano-Reinforced Composites

Sustainable growth can be achieved by recycling waste material into useful resources without affecting the natural ecosystem. Among all nanomaterials, carbon nanomaterials from biowaste are used for various applications. The pyrolysis process is one of the eco-friendly ways for synthesizing such carbon nanomaterials. Recently, polymer nanocomposites (PNCs) filled with biowaste-based carbon nanomaterials attracted a lot of attention due to their enhanced mechanical properties. A variety of polymers, such as thermoplastics, thermosetting polymers, elastomers, and their blends, can be used in the formation of composite materials. This review summarizes the synthesis of carbon nanomaterials, polymer nanocomposites, and mechanical properties of PNCs. The review also focuses on various biowaste-based precursors, their nanoproperties, and turning them into proper composites. PNCs show improved mechanical properties by varying the loading percentages of carbon nanomaterials, which are vital for many defence- and aerospace-related industries. Different synthesis processes are used to achieve enhanced ultimate tensile strength and modulus. The present review summarizes the last 5 years’ work in detail on these PNCs and their applications.

The graphite content is changed from 2%, 6%, 8% with average grain size 20 µm homogeneously distributed throughout the aluminium matrix resulting in the formation of three different specimens. Followed by the determination of Microstructure, Mechanical properties, Tribological, characteristics and Machinability (MRR). Finally comparison between the three specimens.

Distribution of Biominerals and Mineral-Organic Composites in Plant Trichomes.

Biomineralization is a common phenomenon in plants and has been shown to be chemically, functionally and topologically diverse. Silica and calcium carbonate have long been known as structural plant biominerals and calcium phosphate (apatite)–long known from animals–has recently been reported. Strikingly, up to three different biominerals may occur in a single trichome in, e.g., Urticaceae and Loasaceae, and in combination with organic compounds, can form organic/inorganic composite materials. This article presents an extension of previous studies on the distribution of these biominerals in Loasaceae trichomes with a focus on their spatial (three-dimensional) distribution and co-localization with organic substances. Light microscopy and scanning electron microscopy with high-resolution EDX element analyses of sample surfaces and sections illustrate the differential distribution and composition of the different biomineral phases across cell surfaces and cell walls. Raman spectroscopy additionally permits the identification of organic and inorganic compounds side by side. All three biominerals may be found in a nearly pure inorganic phase, e.g., on the plant surfaces and in the barbs of the glochidiate trichomes, or in combination with a larger proportion of organic compounds (cellulose, pectin). The cell lumen may be additionally filled with amorphous mineral deposits. Water-solubility of the mineral fractions differs considerably. Plant trichomes provide an exciting model system for biomineralization and enable the in-vivo study of the formation of complex composite materials with different biomineral and organic compounds involved.

Study of the structure and properties of a high-entropy ceramic composite material

The article describes the technology development of layered surface compositions, including a high-entropy layer of a material with high-temperature memory effect of TiNiZrHfCoCu and a high-temperature ceramic layer based on zirconium dioxide ZrO2 stabilized by Y2O3. The authors also studied the structure, functional and mechanical properties of the abovementioned compositions. The proposed technology was implemented on a patented multifunctional technological complex for the formation of composite layered materials on the surface of steel products in a single technological cycle. On the basis of complex X-ray diffraction and electron microscopic studies, the structural parameters of the constituent layers of the surface composition were determined with subsequent thermal and thermomechanical treatment. The tests for ‘friction-wear’ and mechanical multi-cycle fatigue of the constituent layers of the surface composition showed a decrease in wear intensity and an increase in cyclic durability compared to the steel base. The comparison of wear intensity and cyclic durability of the surface-modified layers of the layered composition TiNiZrHfCoCu-ZrO2(Y2O3) with the composite materials obtained and studied by the authors earlier allowed the recommendation of the surface composition ‘high-entropy alloy TiNiZrHfCoCu-high-temperature ceramics’ for products of various purposes.

Grinding, Melting and Reshaping of EoL Thermoplastic Polymers Reinforced with Recycled Carbon Fibers

This article assesses the technical feasibility of a recycling process based on grinding, melting and re-shaping of carbon fibers (CFs) reinforced thermoplastic polymers, in order to obtain new products that can be introduced in different markets, depending on mechanical properties retained. The idea at the basis of our study is that this kind of recycling process lies at the edge of the stages of recycling and re-use of materials, considering that the latter is preferable when considering the waste management hierarchy. Lower cost and similar mechanical strength of virgin CFs allowed the spread of recycled CFs in the automotive sector in the form of composite materials. Taking into account the Directive 2000/53/EC that sets out measures to prevent and limit waste from end-of-life (EoL) vehicles and their components, and ensures that where possible this is reused, recycled or recovered, we considered worth to investigate the recyclability of composite materials made with recycled CFs when they will reach the state of EoL materials. Considering this premise, an additional scope of this paper is therefore to provide some useful information about the possibility to perform a multiple closed loop recycling of rCF thermoplastic composites. Experiments carried out demonstrated that re-shaping of composites is technically feasible. Some square plates were produced without any setback. The mass balance of the recycling process demonstrated that about 88% of the EoL material can be recovered. Calculation of energy consumption showed that approximately 16 MJ are necessary in the treatment of 1 kg of EoL composites.

Investigation on the Thermo-Oxidative Degradation of Polyethylene, Poly(vinyl chloride), and Polystyrene Using NiPIm1.5 and NiPIm2 Nanocomposites.

In this work, we report the synthesis of two nanoscale composites of nickel, NiPIm1.5 and NiPIm2 (NiPIm1.5 = [Ni(C3H4N2)(H2O)5](HPO4)(H2O)·0.3(C3H4N2) and NiPIm2 = [Ni(C3H4N2)(H2O)5](HPO4)(H2O)·0.4(C3H4N2)·H2O), characterization by various instrumental methods and the investigation of the thermo-oxidative degradation of polyethylene (PE), poly(vinyl chloride) (PVC), and polystyrene (PS) in the presence of both nanocomposites. All of these polymers are subjected to thermal treatment with and without composites at 353 K for 120 min. The rate of degradation is maximum with NiPIm2 for all three polymers, PE—13.1522%, PS—13.6152%, and PVC—8.04%, whereas with NiPIm1.5, PE—7.3128%, PS—11.9837%, and PVC—4.9106%. The percentage of degradation in the presence of composites is much greater than the percentage of degradation without composites. The specific heat capacities of NiPIm1.5 and NiPIm2 are −148.42 and −348.64 J kg–1 K–1, respectively. The degradation process takes place by free radical mechanism. Thermogravimetric and differential thermal analyses revealed that the temperatures corresponding to the formation of composite materials with NiPIm2 are 338.76, 331.78, and 354.30 K for PE, PVC, and PS, respectively. The temperatures of formation of the above composites are found to be less than that of NiPIm1.5. The degraded residues of polymers indicate that ester is formed in each case along with other byproducts containing imidazole. Infrared studies revealed the thermal oxidation of hydroperoxides and the formation of ketone.

Isostructural M 2pt (M = Al, Ga, In, Sn) As OER Anode Materials

Looking for the future energy infrastructure, hydrogen will play an important role as energy carrier molecule. Among different physical and chemical methods of hydrogen production, water electrolysis has numerous advantages. However, the sluggish kinetics of anodic oxygen evolution reaction (OER) hinders its large-scale implementation. The intensive search for new OER electrocatalytic materials is limited by harsh oxidative conditions and instability/ changes of electrocatalyst under reaction conditions. Platinum is characterized by pronounced stability against dissolution compared to other noble metals. However, the OER activity of Pt is one of the lowest one. Combining the platinum with main group elements in form of M 2Pt intermetallic compound will lead to the different electronic state of Pt and, correspondingly, different OER activity.The compounds M2 Pt (M = Al, Ga, In, Sn) crystallize with cubic anti-CaF2 type of crystal structure [1]. Due to the pronounced charge transfer from M to Pt, Pt atoms are negatively charged in these compounds. There is only one type of strongly polar covalent interactions between M and Pt atoms. The OER activity decreases in the following sequence In2Pt > Ga2Pt > Al2Pt. This trend is governed by the chemical nature of the counterpart elements M (M = Al, Ga, In) and their leaching rates under OER conditions. The leaching of M into the electrolyte leads to formation of composite material of intermetallic M2 Pt and Pt-rich phase in the near-surface region. The inactivity of Sn2Pt is due to the formation of passivating SnO2 layer with poor electrical conductivity.The study of OER activity of M 2Pt materials under different electrochemical treatments was combined with surface- and bulk characterization of electrodes after electrochemical experiments, elemental analysis of electrolyte and quantum chemical calculations. This allows to investigate the influence of chemical nature of counterpart element M onto the OER performance of isostructural M 2Pt electrode materials [2].[1].

The effect of composite placement technique on the internal adaptation, gap formation and microshear bond strength.

This study aimed to compare the efficiency of placement technique on internal adaptation, gap formation and microshear bond strength (SBS) of bulk-fill composite resin materials. Standardized class V cavities were prepared for microcomputed tomography (mCT) test and divided into four groups (n=12) as follows: Group SDR: Smart Dentin Replacement system/bulk fill; Group SF2: Sonic-Fill system/bulk fill sonic-activated composite placement system; Group CHU: Herculite-XRV-Ultra composite resin inserted with Compothixo/sonic-vibrated composite resin placement system; Group HIT: Herculite-XRV-Ultra composite resin applied with incremental technique. Self-etch adhesive (Optibond-XTR) was used for bonding in all groups. After 10000 thermocycling, mCT scans were taken to reveal gap formation at the toothrestoration interface and universal testing machine was used to test microshear bond strength SBS values (n=10). ANOVA, post-hoc Bonferroni and Tukey HSD tests were used for evaluating the gap formation and SBS values p=0.05. SF2 and CHU showed the best adaptability compared with both SDR and HIT. The difference between groups SDR and HIT was statistically significant (p<0.05).SBS values were found to be the highest for SF2, and the lowest for HIT groups (p>0.05). Bulk-fill composite resins placed either with sonic-activated or sonic-vibrated instrument demonstrated better adaptability, less gap formation and higher bond strength than both the bulk-fill flowable composite and conventional incremental techniques.

Preparation and Application of 2D MXene-Based Gas Sensors: A Review

Since MXene (a two-dimensional material) was discovered in 2011, it has been favored in all aspects due to its rich surface functional groups, large specific surface area, high conductivity, large porosity, rich organic bonds, and high hydrophilicity. In this paper, the preparation of MXene is introduced first. HF etching was the first etching method for MXene; however, HF is corrosive, resulting in the development of the in situ HF method (fluoride + HCl). Due to the harmful effects of fluorine terminal on the performance of MXene, a fluorine-free preparation method was developed. The increase in interlayer spacing brought about by adding an intercalator can affect MXene’s performance. The usual preparation methods render MXene inevitably agglomerate and the resulting yields are insufficient. Many new preparation methods were researched in order to solve the problems of agglomeration and yield. Secondly, the application of MXene-based materials in gas sensors was discussed. MXene is often regarded as a flexible gas sensor, and the detection of ppb-level acetone at room temperature was observed for the first time. After the formation of composite materials, the increasing interlayer spacing and the specific surface area increased the number of active sites of gas adsorption and the gas sensitivity performance improved. Moreover, this paper discusses the gas-sensing mechanism of MXene. The gas-sensing mechanism of metallic MXene is affected by the expansion of the lamellae and will be doped with H2O and oxygen during the etching process in order to become a p-type semiconductor. A p-n heterojunction and a Schottky barrier forms due to combinations with other semiconductors; thus, the gas sensitivities of composite materials are regulated and controlled by them. Although there are only several reports on the application of MXene materials to gas sensors, MXene and its composite materials are expected to become materials that can effectively detect gases at room temperature, especially for the detection of NH3 and VOC gas. Finally, the challenges and opportunities of MXene as a gas sensor are discussed.

In situ CaCO3 mineralization controlled by carbonate source within chitosan-based cryogels

Designing of multifunctional hydrogel/CaCO3 composites has received great interest in the modern tissue engineering. Herein, four chitosan-based cryogel samples as monoliths, prepared by ice-segregation technique and which differ by structural porosity, are proposed as possible matrix for CaCO3 crystal growth, aiming the formation of homogeneous composite materials. Also, four types of carbonate sources were applied as modulators for crystal growth: Na2CO3 in an alternate dipping process, dimethyl- or diethyl-carbonate (DMC or DEC) hydrolysis, and ammonium bicarbonate diffusion. The morphology of the composites was investigated by scanning electron microscopy and the polymorphs characteristics by X-ray diffraction and FTIR-ATR spectroscopy. The crystal growth applied methods were effective for composite formation, tuning the inorganic formation in the whole cryogels 3D pattern. Thus, increasing the number of alternate sorption steps, the amount of CaCO3 crystals increased but keeping the pores open for further specific applications. Also, CaCO3 polymorphs formed by DMC or DEC hydrolysis show mainly the formation of calcite rhombohedral crystals arranged in large polycrystals. The ammonium diffusion method generated the most uniform structures, in the whole investigated cryogels samples, MTS test showing samples biocompatibility.

New Concepts Accounting for Variations in the Formation of Multilayer Fiber Composite Materials

New Concepts Accounting for Variations in the Formation of Multilayer Fiber Composite Materials

The Composites of PCL and Tetranuclear Titanium(IV)-oxo Complexes as Materials Exhibiting the Photocatalytic and the Antimicrobial Activity.

Excessive misuse of antibiotics and antimicrobials has led to a spread of microorganisms resistant to most currently used agents. The resulting global threats has driven the search for new materials with optimal antimicrobial activity and their application in various areas of our lives. In our research, we focused on the formation of composite materials produced by the dispersion of titanium(IV)-oxo complexes (TOCs) in poly(ε-caprolactone) (PCL) matrix, which exhibit optimal antimicrobial activity. TOCs, of the general formula [Ti4O2(OiBu)10(O2CR’)2] (R’ = PhNH2 (1), C13H9 (2)) were synthesized as a result of the direct reaction of titanium(IV) isobutoxide and 4-aminobenzoic acid or 9-fluorenecarboxylic acid. The microcrystalline powders of (1) and (2), whose structures were confirmed by infrared (IR) and Raman spectroscopy, were dispersed in PCL matrixes. In this way, the composites PCL + nTOCs (n = 5 and 20 wt.%) were produced. The structure and physicochemical properties were determined on the basis of Raman microscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), electron paramagnetic resonance spectroscopy (EPR), and UV–Vis diffuse reflectance spectroscopy (DRS). The degree of TOCs distribution in the polymer matrix was monitored by scanning electron microscopy (SEM). The addition of TOCs micro grains into the PCL matrix only slightly changed the thermal and mechanical properties of the composite compared to the pure PCL. Among the investigated PCL + TOCs systems, promising antibacterial properties were confirmed for samples of PCL + n(2) (n = 5, 20 wt.%) composites, which simultaneously revealed the best photocatalytic activity in the visible range.

Hierarchical Co3O4 decorated nitrogen-doped graphene oxide nanosheets for energy storage and gas sensing applications

Nano-sized cobalt oxide decorated nitrogen-doped graphene oxide (Co3O4@NGO) composite was produced by a feasible and cost-effective hydrothermal route for electrochemical supercapacitors and gas sensor applications. The composite materials formation was ascertained by Raman spectroscopy, X-ray diffraction, and X-ray photo electron spectroscopy analyses. Field emission scanning electron microscopy (FE-SEM) and field emission transmission electron microscopy (FE-TEM) results explored the controlled nanoscale-sized sheet-like morphology for the prepared composite materials. Electrochemical storage properties were studied by cyclic voltammetry (CV), galvanostatic charge–discharge process (GCD), and electrochemical impedance spectroscopy analyses using three-electrode configuration with 3 M KOH electrolyte. The observed results showed ~466 F/g specific capacitance at a current density of 1 A/g for Co3O4@NGO composite structure with the capacity retention of 96 % after 5000 cycles. Further, the synthesized Co3O4@NGO composite revealed improved detection response, cyclability, and linearity for dimethyl methyl phosphonate vapor gas sensing. The synthesized composite also demonstrated excellent selectivity, stability, sensitivity, and rapid response time.

Effect of different beverages on surface properties and cariogenic biofilm formation of composite resin materials.

The consumption of certain beverages may affect the physical and biological properties of resin composites (RCs) according to type. This in vitro study aimed to evaluate the surface properties and cariogenic biofilm formation in microhybrid and nanohybrid RCs after immersion in different beverages. The effects of four beverages (distilled water-control, tea, coffee, and cola) on two RCs (microhybrid and nanohybrid) were evaluated. Changes in the surface properties were evaluated for each group using surface roughness measurement (n=10), scanning electron microscopy (SEM) (n=4) observation, and energy-dispersive X-ray spectroscopy (EDX) (n=5) analysis. In vitro Streptococcus mutans biofilm formation on the specimens of each group was determined using confocal laser scanning microscopy and SEM analysis (n=14). The data were analyzed using two-way analysis of variance, with Bonferroni as a post-hoc test and Pearson's correlation (p < .05). Microhybrid RC presented more surface roughness (p=.014) and cariogenic biofilm formation (p=.040). The surface roughness (F=0.733, p=.536) and cariogenic biofilm formation (F=1.685, p=.181) values were not affected by the beverages. However, according to qualitative SEM and EDX measurements, these parameters varied depending on the beverage groups. No correlation was found between surface roughness and cariogenic biofilm formation (r=0.135, p=.287). Microhybrid RCs had a rougher surface and a higher amount of cariogenic biofilm formation than nanohybrid RCs after being subjected to different beverages.

Application of non-ionic surfactant in modifying the surface of carbon black and its role in the formation of colloidal composite materials

In this work, carbon black (CB)/silica colloidal composites were synthesized using a surface adsorption methodology. A unique biocompatible, amphiphilic, non-ionic polysorbetol monoelate easter (Tween 80) surfactant was used to enhance surface activity and wettability of CB aggregates. A metal alkoxide (tetraethoxysilane) was used as precursor for silica precipitation in an acid catalyzed reaction. The precipitated silica gets adsorbed onto surfactant modified CB aggregate via an interactive hydrophilic layer. This results in formation of different configurations of CB/silica colloidal composite, which was characterized by morphological studies. The chemical extraction study was done to quantify, the amount of silica present in CB/silica colloidal composites and observation were further supported by energy dispersive x-ray (EDX) analysis. The x-ray diffraction (XRD) characterizes, the structural arrangement of synthesized materials. The surface-free energies studies by inverse gas chromatography (IGC) were done to understand changes in dispersive and polar component of CB-silica composite compared to conventional filler materials. The distribution of silica in CB/silica composite aggregates was uniform up to adsorption level of 5 wt%. Further, increase in the level of silica adsorption leads to flocculation, causing agglomerated composites. The results obtained encourage adaptation of a simple, low-cost and environmentally friendly process to promote synthesis of CB/silica composite material.
