Interesting alternatives to expensive biodegradable polymers are their composites with natural fillers. The addition of biochar to a blend of poly(lactic acid) (PLA) and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) was studied, and the resulting materials were evaluated for their properties and changes during degradation. Introducing biochar as a filler brought a noticeable improvement in electrostatic properties. Surface resistivity decreased from 3.80 × 1012 for the sample without biochar to 1.32 × 1012 for the sample with 30% filler content. Degradation tests revealed distinct differences in the degradation profile for composites due to the presence of filler. Composites with a lower biochar content displayed curling crack edges during hydrolytic degradation, and when the filler content reached 20 wt%, PLA loss accelerated. This study suggests that biochar-based composites have potential to be used as sustainable materials with improved properties.

One of the most significant and basic parameters connected with the performance of rare earth-based high temperature (HTS) coated conductor tapes is the angular dependence of their critical current. Because of the complex tape architecture, com-plicated production process and long length of coated super-conducting tapes, the Ic(B) angular dependence homogeneity of the superconductor along the conductor length needs to be evaluated. In this work, the homogeneity of several samples of SuperPower tapes manufactured between 2008 and 2014 was examined. It was found that, for a given sample, the variation of results of the critical current is at most 6.7%. In addition, the uniformity is dependent on the angular arrangement of the tape in external magnetic field.

This paper presents a modified sine-fitting algorithms which can be used for high-accuracy sampling measurements of complex voltage ratio of sinusoidal signals. The proposed algorithms provide a significant reduction in the measurement uncertainty of phase shift when synchronizing the sampler and signal source is impossible.

This paper describes two calculable thermal ac voltage standards developed at the Silesian University of Technology in Gliwice, Poland. The design and mathematical model of these standards made calculation of their ac-dc transfer differences with very low uncertainty possible, comparable to the uncertainty of the best available calculable ac voltage standards in the 10 kHz-1 MHz frequency range. The correctness of the results of the ac-dc transfer difference calculation was also confirmed experimentally.

In the electrical installations of buildings, there is an increasing number of non-linear energy receivers, which introduce strong distortions of the load current of electronic energy meters. Since the readings of these meters are the basis for financial settlements of electricity consumers, it is very important to determine how much the distortion of the receiver current affects the correct operation of commonly used electronic energy meters. The article will present exemplary results and analyses of research work on the impact of individual current harmonics on the readings and errors of selected energy meters.

Despite the spectacular development of numerical methods, the use of analytical formulas to solve electromagnetism problems in multilayered complex structures still remains attractive due to their much shorter computation time. One of the most essential computations is a calculation on the proximity effects observed in a wire that is immersed in an external harmonic electromagnetic field. The mathematical model of this problem is known and contains Bessel functions, which are numerically unstable for very low and high arguments. In this article, a novel numerically stable algorithm for the computation of proximity effects and power induced in a multilayered cylindrical structure is presented.
