Poly(ethylene glycol) (PEG) hydrogels have been extensively used as scaffolds for tissue engineering applications, owing to their biocompatibility, chemical versatility, and tunable mechanical properties. However, their bio-inert properties require them to be associated with additional functional moieties to interact with cells. To circumvent this ...

Bioprosthetic heart valve (BHV) replacement is increasingly used for treating valve-related diseases worldwide but the current commercially used BHVs treated with glutaraldehyde (Glut) often failed within 12-15 years due to degradation, thrombosis, inferior biocompatibility, and calcification. Herein, 3-glycidyloxypropyl trimethoxysilane (GPTMS) wa...

This study has investigated the effect of tool offset on the mechanical behavior and microstructure of dissimilar copper and brass joints by friction stir welding (FSW). In this regard, the FSW method was used for joint with three different tool offset positions, namely center line (no offset), the copper side, and the brass alloy side. Microstruct...

AbstractThe factors determining the mechanical properties of plastic polymeric foams are systematized. A unification procedure for their deformation behavior in the range of strains not higher than the forced elasticity limit of the material is proposed. The universal character of the deformation process is described by a unified strain curve and r...

AbstractThe structure and mechanical properties of 09G2S steel are studied during uniaxial tension tests in the temperature range from room temperature to 1200°C. The temperatures above which the strength properties of the steel decrease are determined. Austenite grain growth is shown to be very weak in the temperature range from room temperature t...

AbstractThe mechanical properties and structure of a layered composite material based on a Ti–6Al–4V alloy and fabricated by diffusion welding of plates with different grain structures are studied. The outer plates of the material have a microcrystalline structure, and the intermediate plate (reinforcing element) has a nanocrystalline structure. At...

AbstractThe influence of tempering at temperatures of 300–650°C on the mechanical properties of austenitic–martensitic VNS9-Sh TRIP steel under static tension and fatigue conditions, on its phase composition, and on the residual macrostresses in it is studied. A significant change in the mechanical properties is detected after tempering at 500°C or...

Pri uporabi aditivnih tehnologij lahko tiskamo izdelke z zelo širokim naborom filamentov, ki so običajno mešanica nekega izbranega materiala in polimerov, ki se vežejo v obliko. Določitev materialnih lastnosti polimernih materialov, kot so natezna trdnost in elastični modul, se lahko določi v sladu s standardnim nateznim preizkusom. Za razliko od k...

AbstractThe production of strong metal matrix composites by pressure welding at low temperatures is considered. Failure of the composite is analyzed. It is found that the strength of a composite produced at 700°C may exceed that of a composite produced at 900°C.

This work describes the mechanical properties and metallurgical characterization of Friction Stir Processing (FSP) on TIG welded dissimilar AA5052-H32 and AA5083-H111 alloys using ER5356 filler wire. A comparison is drawn between unprocessed TIG weld and FS Processed (FSPed) TIG welded specimen with the identical combination. The fabricated welded ...
