Carbonized elastomer-based composites (CECs) possess a number of attractive features in terms thermomechanical and electromechanical performance, durability aggressive media facile net-shape formability, but their relatively low ductility strength limit suitability for structural engineering applications. Prospective applications such as elements micro-electro-mechanical systems MEMS can be envisaged since smaller principal dimensions reduce the susceptibility components to residual stress...
This work evaluated the fracture toughness of low-temperature carbonized elastomer-based composites filled with shungite and short carbon fibers. The effects carbonization temperature filler content on critical stress intensity factor (K1c) were examined. K1c parameter was obtained using three-point bending tests for specimens different l/b ratio (notch depth to sample thickness) ranging from 0.2 0.4. Reliable detection initiation propagation cracks achieved an acoustic sensor attached...
Introduction. Captan is a contact fungicide from the phthalimide class, used in agriculture to combat plant diseases. However, question of its genotoxicity for humans remains open. Various studies examining mutagenic activity captan using different tests have yielded conflicting results. This study aims investigate potential induce DNA damage human peripheral blood lymphocytes vitro single-cell alkaline gel electrophoresis. Material and methods. The DNA-damaging effect (0; 2.5; 5.0; 10.0;...
Introduction. Available data indicate the SARS-CoV-2 coronavirus to be potent of impairing DNA repair processes and cause oxidative stress, which can lead accumulation damage in human cells. However, DNA-damaging effect virus has not yet been sufficiently studied. The purpose research was study ability peripheral blood lymphocytes. Materials methods. One hundred forty COVID-19 patients 24 donors control group are included study. level fragmentation lymphocytes determined by alkaline...
In this study, composites obtained through low-temperature carbonization of elastomeric matrix highly filled with graphite, carbon black and short fibers were studied for the purpose determining residual stresses at different scales using a combination several complementary methods. The state-of-the-art techniques included X-ray stress analysis <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Introduction. Over recent decades, toxicogenetic studies have focused on the issues of genome instability under action genotoxicants, taking into account biomarkers sensitivity. The question about genotoxic potential chlorpyrifos remains open, since both positive and negative effects been revealed in various tests. aim study is investigation sensitivity donor peripheral blood lymphocytes to vitro evaluation contribution polymorphism antioxidant defense system genes (CAT (rs1001179), SOD2...

Epoxy matrix composites reinforced with high-performance fibers such as carbon, Kevlar, and glass, exhibit excellent specific stiffness strength in many mechanical applications. However, these are disappointingly non-recyclable usually disposed of landfill sites, no realistic prospect for biodegradation reasonable time. In contrast, moldable carbonized elastomeric matrices developed the last decades possess attractive properties final net-shape products can also be incinerated or recycled....

Thermally stable composites obtained by the low-temperature carbonization of an elastomeric matrix filled with hard dispersed silicon carbide particles were and investigated. Evolution microstructure mechanical thermal characteristics during degradation processes in a wide range filling from 0 to 450 parts per hundred rubber was studied. For highly composites, compressive strength values found be more than 200 MPa; Young's modulus 15 GPa. The conductivity coefficient up 1.6 W/(m·K), this...
