We compare the cost of a high temperature superconducting (SC) tape-based solenoid with a permanent magnet (PM) Halbach cylinder for magnetic refrigeration. Assuming a five liter active magnetic regenerator volume, the price of each type of magnet is determined as a function of aspect ratio of the regenerator and desi…
In this study, parameters which influence the chemical modification under mild conditions using a weak organic acid, fatty acids of unsaturated oil, cottonseed to produce epoxidized oil, which is a useful precursor in obtaining resins epoxy industrial importance, were evaluated. We studied the following reaction param…
Polydimethylsiloxane (PDMS) elastomers employing conductive fillers are used in many applications for e.g. flexible electrode materials or with lower amounts of fillers for high capacitance elastomers. Traditionally, the most used filler in these applications has been carbon black, which through high loading results i…

The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space grou…
In aquatic toxicity testing of engineered nanoparticles (ENPs) the process of agglomeration is very important as it may alter the bioavailability of the ENPs and hence their toxicity. In this study we evaluated test conditions that are more favorable in maintaining a stable and low agglomerate size profile of ENPs in…
In the article is given a qualitative evaluation of the quality of rebar produced in the conditions of the shape rolling mill of JSC ArcelorMittal Temirtau. It is revealed that the mechanical properties are not the most critically depends on the quality of the chemical composition; significant impact on quality is als…
The main aim of this work was to measure the oxidation characteristics of H2, CH4, C2H6, DME,and ethanol at high pressures (20—100 bar) and low to intermediate temperatures (450—900K) in a laminar flow reactor. Furthermore, a detailed chemical kinetic model was sought to address the oxidation of aforementioned fuels a…
The material dynamic behaviour of components of rail vehicle subjected to impact loading is of great importance in terms of evaluating dynamic strength behaviour and stress-strain responses. It is also quite necessary objective to be able to understand the strengthening mechanisms depending \non rate of loading during…
Surface protecting ability of 1, 3, 3-trimethyl -2, 6-diphenyl piperidin-4-one oxime (TPO) against mild steel (MS) in 1M sulphuric acid medium has been investigated by weight loss study, electrochemical methods, SEM and theoretical studies. The weight loss studies were conducted at four different temperatures such as…
The polishment is the main type of finishing performed in slabs and tiles of rocks, which is done by the friction generated in the rotational motion of abrasive elements disposed in polishing heads, under pressure, against the rock surface. The rock is an active element in the process, therefore the knowledge of its p…
Covalent Organic Framework (COF) which is a white crystalline nanoporous material, has a very high specific surface area, rigid structure and low in density. COF is made up of light elements which are covalently bonded together and has been studied extensively as a material for gas storage. However, elementary studies…
Identifying types of Partial Discharge (PD) is very crucial in order to prepare and provide solutions before complete breakdown occurs. Before PD can be identified, detection of the PD is initially required and it can be made by ultrasonic and electrical methods. By using ultrasonic methods, the obtained PD data is co…
Novel ligand based on phenylazo of resorciacetophenonel-Formaldehyde polymer was synthesized by diazotization reaction of resorciacetophenonel-Formaldehyde polymer with phenyl diazoninum salt. Co-ordination polymers of this ligand were prepared with Cu(II),Ni(II),Co(II),Mn(II) and Zn(II) metal ions. All of these coord…
Le pareti sono uno degli elementi funzionali caratterizzanti delle cellule vegetali, dove biosintesi, assemblaggio e rimodellamento sono sotto stretto controllo genetico e ambientale. La principale macchina molecolare coinvolta è la cellulosa sintasi, la cui attività permette la polimerizzazione degli zuccheri in ce…
Optical trapping is the use of a laser beam, to trap small particles, similarly to using tweezers. A straight beam of light, focused correctly, can provide a force strong enough to control a nanoparticle. The objective of this project is to set up a Modular Optical Trapping Kit for the purposes of research and teachin…
