Abstract: In our study, we aimed to synthesize superparamagnetic nanoparticles (PMPs) able to isolate and immobilize and thus preconcentrate flavonoids for subsequent analysis. We report the optimal conditions such as different pH of Britton Robinson buffer, temperature and time of incubation on the isolation of different types of flavonoids, such as Genkwanin and Pratol from extracts of freshwater algae.

Abstract: Biocompatible and bactericidal coatings were deposited onto different titanium based implant materials. For this the plasma chemical oxidation (PCO) process as well as the atmospheric pressure plasma chemical vapour deposition (APCVD) was used successively. [..] Read more

Abstract: This paper presents intensively cooled ingot during casting and solidification and comparison of obtained results with numerical simulation in Magma 5 software. The technology of intensive cooled ingot has been developed and physically verified in MATERIAL AND METALLURGICAL RESEARCH Ltd. [..] Read more

Abstract: Many parts for automobiles and home electric appliances are made of steel sheets. In sheet metal forming processes, the knowledge of technological values, such as yield or tensile strength and r-value, enables a more precise control of processes and results in many benefits such as an improvement in yield efficiency in machining processes and a decrease in loss of material.

Abstract: The aim of the paper is to present the possibility of application the fuzzy sets theory to support warehouse management. In the second chapter the basic issues relating to fuzzy sets and fuzzy logic are presented. [..] Read more

Abstract: The paper provides a qualitative analysis of the proposal to introduce SWIBŻ into creation of Polish Port Community System. The key information from SWIBŻ system would be widely used by national and international administration institutions in order to achieve expected level of shipping monitoring and control.

Abstract: The hot deformation behavior of NIMONIC 80A was studied in the temperature range of 900 ~ 1200°C by employing the hot compression tests with the strain rates varying between 0.02~20 s-1. The results showed that the strength during hot compression increased with increasing the strain rate and decreasing temperature. [..] Read more

Abstract: Lightweight is one of methods for low-carbon design. Based on the lightweight applications potential of metal composite bulks and on the fact that the interface between metals is externally visible currently, this study aims to investigate the feasibility to create core-shell type metal composite bulks.

Abstract: In recent years, a high development of the length of bicycle paths in Polish cities can be observed. Along with their increase, there are also many elements of road infrastructure that improve the safety and comfort of traveling cyclists in cities. [..] Read more

Abstract: Currently, 3D-printing of smart materials is actively developing. Alloys based on intermetallic compounds Ni-Mn-Ga and Ni-Co-Al are of great interest due to the ability to manipulate their deformation behavior by external magnetic field with much higher effect than in conventional magnetostrictive materials.

Abstract: At present, cast iron foundries are facing increasing competition along with increasing demand for ductile iron. Therefore, there is no other way than to improve the technological processes of casting production and use other possibilities for more efficient management of their quality by means of 3D scanning of dimensional accuracy in critical production nodes.The paper is based on the gained experience with the study of the potential of the method of non-contact 3D measurement of shape and dimensional accuracy of the patterns and castings, which is to be used in optimizing the process parameters of gravity casting of ductile iron castings.The ROMER Absolute Arm 7525SI portable laser measuring arm is used.

Abstract: One of the methods of evaluating the mechanical properties of a material in the case of its limited amount l is the use of techniques that employ the miniaturized test specimens. The basic properties used mostly for residual life evaluation are tensile strength, impact notch toughness or impact notch toughness transition curve, fracture toughness, creep and high cycle fatigue.
