Favorable physical and chemical properties of titanium led to its use in the medical and dental specialties such as: orthodontics, prosthodontics, dental implantology and dental surgery. Estimating the biocompatibility of the material, determine the risks and benefits with its use is a complex process. In dental implantology, the attachment of a dissimilar metal abutment (Ti6Al4V) to an implant (commercially pure Ti) forms a galvanic couple in the mouth; they are placed in physical contact in an electrically conductive mediums – body fluids.

AbstractOwing to their peculiar physical and chemical properties, carbon nanotubes are intensively studied for many different applications, including those in the biomedical field. Carbon nanotubes are electrically conductive, elastic but mechanically resistant and these features, among others, have made them an ideal material for therapeutic applications at the neural tissue interface. The major recent advances in the study of carbon nanotube-based materials aimed at nerve tissue regeneration and functional recovery are reviewed here.

This review article elaborates the pH and nutrients detection sensitive materials and methods along with their principle of operations, merits, demerits, and application area. The sensitive materials used in the sensors react with the analytes and shows variation in electrical, physical, chemical, biological and optical parameters. The glass probe method, optical light spectroscopy, ion-selective electrodes, ion-selective field effective transistors, electrochemical interdigitated conductimetric method and microcantilever methods are the predominant techniques to detect the pH and nutrients in various medium. Most of the researchers have discussed the fabrication of pH and nutrients sensors individually in various applications, but very few numbers of sensitive materials and techniques discussed to detect the pH and nutrients in the soil. There is a strong relationship between pH and nutrients in the soil based on a number of important physical and chemical properties of the soil. We are strongly recommending that soil pH and nutrients measuring sensors can develop through the combinational approach of pH and nutrients with the help of nanostructured materials, seems to be more effective for agriculture applications.

The present study is based on nano technology and came up with the idea of introducing nanoparticles in the raw materials used for construction. Nano materials are available in three principal shapes 0, 1 and 2 Dimensional nanoparticles. 0D and 1D nanofibers are such as carbon nanotubes and nanosilica compounds. This study has investigated the physical and chemical properties of graphite and graphene compound and its applicability in construction industry.  Graphene has created interest as it is believed to improve the strength of concrete allowing the possibility of controlling properties of concrete. In this work graphene is used as a reinforcing additive in cement-based mortar and concrete. Own Graphene compound is prepared using conventional graphite and concentrated hydrogen peroxide in the laboratory due to the unavailability of graphene. As a part of microstructural investigation, SEM and EDS analysis on graphite and graphene compounds before and after implementation are carried out in the laboratory. Then the two compounds are replaced as a part of small percentage in cement mortar cubes casted for various proportions. The mechanical properties of cement-based composites are studied after incorporating of graphite and graphene compounds at low dosages in concrete and then the results are compared.

Abstract The printability properties of the paper can be increased by some processes applied to the surface. The use of non-recyclable materials derived from petroleum is decreasing day by day, and the demand for recyclable materials obtained from renewable sources is increasing. These materials include cellulose derivatives, starch types and polyvinyl alcohol. The materials ratios, sizes, physical and chemical properties of these materials used in the processes applied to the paper and the content of the paper will affect the strength of the paper as well as change the surface properties and significantly affect the printability.In this study, fluting and core board papers coated with different amounts of cellulose nanofiber/ cellulose nanofiber-oxidized (CNF/CNF-OX) were produced. Surface properties, contact angle, surface energy, color and gloss of the produced papers were measured by optical microscope, goniometer, spectrophotometer and glossmeter. The papers were printed with the IGT C1 offset printability tester. The color and gloss properties of the printed papers were measured. As a result, in terms of printability, it was determined that CNF/CNF-OX coated papers have smoother surfaces and give better results in terms of both gloss properties and printability.

Summary. The article considers current issues of modern medicine, in particular the use of the method of transarterial embolization of blood vessels in the treatment of malignant tumors of the extremities. The purpose, indications, technical features and materials used for its implementation, as well as contraindications and complications are highlighted. Its efficiency in preparation of the patient for a surgery of musculoskeletal malignant tumor is considered. Analysis of the modern domestic and foreign literature shows that now indications for use of this method expand, and technical possibilities of the equipment and physical and chemical properties of materials improve. The issues of further study and development of the problem are outlined.

It is generally acknowledged that porcelains, among portable antiquities, boast relatively stable physical and chemical properties. However, marine archaeological porcelains are likely to suffer from deterioration such as salting out, attachment and corrosion due to the complicated burial environments. In the course of conservation and restoration, some natural diseases are easily mistaken for production defects. In order to preserve as much historical information about the antiquities as possible during the clean — up process, we systematically examined traditional porcelain production methods used at the Yue kiln, and conducted further research on typical production flaws that can easily be confused with the natural diseases. Based on these traditional methods and compositional characteristics of porcelains, we provide some guidance on the selection of clean —up methods and repair materials used for porcelains. From the perspective of identifiability and ageing resistance, this paper focuses on discussing the restoration scale of porcelains exhibited in museums. Based on our practical work, we discuss some problems that should be noticed in restoration and also provide an outlook for the future practical work and research.

In connection with the spectrophotometric study of population-type characteristics of various kinds of stars, a statistical analysis of kinematical and distribution parameters of the same stars is performed at the Toruń Observatory. This has a twofold purpose: first, to provide a practical guide in selecting stars for observing programmes, second, to contribute to the understanding of relations existing between the physical and chemical properties of stars and their kinematics and distribution in the Galaxy.

Synthesis Of Materials

Biomimetics involves investigation of structure, function, and methods of synthesis of biological composite materials. The goal is to apply this information to the design and synthesis of materials for engineering applications.Properties of engineering materials are structure sensitive through the whole spectrum of dimensions from nanometer to macro scale. The goal in designing and processing of technological materials, therefore, is to control microstructural evolution at each of these dimensions so as to achieve predictable physical and chemical properties. Control at each successive level of dimension, however, is a major challenge as is the retention of integrity between successive levels. Engineering materials are rarely fabricated to achieve more than a few of the desired properties and the synthesis techniques usually involve high temperature or low pressure conditions that are energy inefficient and environmentally damaging.In contrast to human-made materials, organisms synthesize composites whose intricate structures are more controlled at each scale and hierarchical order.
