Biomass fibers are promising materials for applications in modern vehicles. They have great economic and ecological significance, as well as a great potential in the fabrication of composite materials due to the relatively high level of strength and rigidity, low density, availability, recyclability, and biodegradability. In this context, the focus is on the development of automotive brake pad materials from sustainable sources. This work refers to the investigation of the behavior of composite materials made of biomass fibers, phenolic resin, graphite and aluminum oxide. These materials are intended to be used for brake pads on automobiles with moderate efficiency. For this purpose, three recipes of composite materials with different percentages of coconut fiber and wood powder were developed in laboratory. The physical and mechanical as well as functional properties of these composite materials with varying amounts of biomass fibers are examined in this paper. The best performances in this terms was obtained for the composite material containing the highest amount of wood powder and the lowest amount of coconut fiber.

Lignin fiber/epoxy resin compositeused for energy absorbing was prepared by atmospheric stirring method. Quasi-static compressive mechanics tests were implemented by using the electronic universal mechanics tester (WDW-100KN) under ambient conditions to analyze the compressing behavior of the matrix material and composite at the strain rate of 10-2s-1 .Scanning electron microscope (SEM) was used to observe the microstructure of the composite after quasi-static compression damage. The results showed that when the ratio of epoxy resin and curing agent was 3:1, the internal structure of the matrix material was more uniform with smoother cross-section, which represented better mechanical properties. It was found that the addition of lignin fiber changed the compression characteristics of the matrix material, resulting in a strengthening stage appeared. At the same time, when the lignin fiber content was 2% or 3%, the composite could absorb more impact energy and delay crack generation, which met the performance requirement of energy absorbing materials.

This study aimed to evaluate the efficacy of disinfectant solutions on Candida albicans (C. albicans) for different types of denture materials. A total of 144 specimens (10x10x2 mm) were obtained from three different materials: autopolymerized acrylic resin, heat-cured acrylic resin, and hard relining material (n = 6). Three disinfectant solutions were used: 100% white vinegar, 2% chlorhexidine digluconate (Saver) and denture cleaning tablets (Corega). The specimens were placed on Eliza plates and 1.5 mL of Yeast Extract Peptone (YPD) was added to each well. Then, 30�L of candida culture was added to the wells. Next, the specimens were incubated at 37�C at 80 rpm for 48 h. Disinfectants were added to the Eliza plates. For all specimens, the disinfectants were replaced with 2 mL of sterile water and kept at 100 rpm for 30 min. Then, 0.1 mL of the liquid was taken and inoculated into the pads containing YPD medium. After incubation, the candida colony growth on the pads was measured. Scanning electron microscope (SEM) images were taken from randomly selected specimens from each group. Statistically significant differences (𝑃 [ 0.05) were found between the disinfectant method groups and the control group for the three types of denture materials. The 2% chlorhexidine gluconate (Saver) disinfectant was the most effective for C. Albicans ATCC 60193 and oral isolate of C. Albicans for all three of the tested denture materials. The effect of cleaning of tabs (Corega) and white vinegar was found to be similar.

The materials of the given article are devoted to the problem solution associated with one of the processing plastic waste methods by adding various fillers in order to obtain the final product for the thermal insulation materials manufacture. The researches were conducted using the UPR (unsaturated polyester resin) samples made of EPS (expanded polystyrene) plastic waste and crushed recycled polyethylene from greenhouse film waste with various types of wood waste from carpentry workshops. The tests have revealed that when EPS is added to the unsaturated polyester mixtures, the EPS thermal conductivity coefficient decreases with a slight decrease in density, which gives the wide opportunities to use EPS waste as an additive for UPR and expands the ways of its potential industrial application, and the addition of styrene to the compositions containing 10% of styropor causes a clear decrease in thermal conductivity characteristics and a slight decrease in the density of these mixtures. The values of the thermal conductivity coefficient and the density of the low-density polyethylene material increase with the wood powder percentage raising used as an organic filler.

The etiology of maxillofacial injuries is represented by car accidents, human aggression, and work-related trauma. Trauma to the maxillofacial area requires a complex treatment that involves functional and aesthetic rehabilitation. To restore the functionality of the damaged areas, a correct surgical technique is necessary along with the use of the ideal prostheses for a better reconstruction. Along with the development and improvement of facial fractures osteosynthesis techniques, an attempt was made to identify the right material to complete these surgical methods. We analyze in this paperwork the benefits of polyetheretherketone-based materials in the prosthetics of different facial fractures in comparison with other materials like titanium.

Biodegradable bio composites with potential applications in medical implants were prepared with starch content by in situ polymerization technique using polyurethane prepolymers. (PU) and acrylamide (AAM) monomers. The structure and properties of bio composites were evaluated. FT-IR spectroscopy showed bonding between N=C=O functional group terminated polyurethanes confirmed improved compatibility of prepolymers, AAM, starch and bio composites. The DSC data are the glass transition (Tg) of the bio composite and ordinary polyacrylamide (PAAM) network. By incorporating starch and polyurethane in the form of an interpenetrating network into a polyacrylamide network, mechanical and thermal properties of bio composites due to higher crosslink density given by hard segment content. We studied the swelling behavior of both bio composites and individual PAAM networks under different pH conditions to validate their biocompatibility and potential use in biomedicine setting. The hydrolytic stability of biocomposites and PAAM networks was investigated using phosphate buffer. Hydrolytic stability of biocomposites was found to be higher comparison with PAAM network. Morphological analysis of the samples showed uniform distribution and good interfacial adhesion. Improves sample biodegradability it was revealed by the soil runoff test.

Industrial vacuum cups are used for lifting, holding and moving a wide variety of automated applications for handling semi-finished products and parts made of a wide range of materials - metal, glass, plastic, paper, wood, etc. and are used in a variety of industries. This paper presents some of the authors theoretical and experimental research on the maximum lifting force that different types of vacuum cups can achieve. The study was carried out on the basis of sizing recommendations made by manufacturers and dealers of these types of vacuum cups. The specially designed experimental stand was installed on the universal material testing machine LBG 100 kN and allowed the practical determination of these lifting forces provided by various types of industrial vacuum cups. Lifting force measurements were carried out with the AXIS FB 1k digital dynamometer attached to the machine. Vacuum cups of 3 different shapes and made of 3 different materials were used, using different vacuum depressions - 0.3 bar, -0.5 bar, -0.7 bar and -0.9 bar. The research aimed to determine by measurement the maximum lifting force of these types of vacuum cups applied to steel parts. The results obtained for these forces were compared with the calculated theoretical values, with the manufacturer�s recommended dimensioning values, and comparative conclusions were also drawn on the maximum lifting force provided by the different types of industrial vacuum cups studied.

Bromelain, a natural substance sourced from pineapples, was found effective in various colds, in preventing heart attack and respectively in excess weight. On the other hand, it is well-known that pineapples juice increases the gastric acidity and respectively the people with hemophilia, internal bleeding must also be very careful in consuming this fruit. The objectives of this study were to obtain and to characterize a drug delivery system used for the transmembrane transfer of bromelain. The samples based on polyurethane matrices with and respectively without bromelain were synthesized and characterized by measurements of pH, encapsulation efficacy, cumulative drug release in a degradative media and in simulated gastric acid, electron microscopy and by modern techniques such as Zetasizer, cytotoxicity assay, and various non-invasive skin irritation assessment. The results indicate the obtaining of polyurethane matrices with mean sizes between 322-342 nm and neutral pH, that have a medium stability against the clusters formation tendency and a medium drug release rate. The non-irritative potential and the results on their cytotoxicity are important evidences that can be used for the further clinical trials of the polyurethane carriers.

Main goals like technical innovation, costs and respect for the environment urge us to discover finer, lighter, biodegradable, and more �intelligent� materials in their functionality. The development of industrial design is motivated by criteria such as the environment, sustainability, the need for lightweight products, manufactured with fewer components and integrating various functions. As experts in new materials and technologies for the development of innovative products, we work closely with international research institutes as part of our projects. We want to create materials that combine such properties in the most efficient way, interacting with their close environment and the environment in general and, based on their features, to be transformed through various processes in completely different materials. The goal of our work is to compare different existing materials with a new bio-based material using quantifiable measurement indicators and sensory measurement indicators. The purpose of this article is to provide a few elements that can be used as a guide in establishing a quantitative impact assessment strategy based on the use of sensory evaluation techniques. In the framework of our presentation, we will focus mostly on comparing the materials via a metrological tool for quantifying tactile characteristics likely to be correlated to the ground truth that constitutes a sensory profile.
