Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

In this paper, efforts have been made to investigate, and compute general formulae of the pyroelectric coefficient and figure-of-merit of pyroelectric-polymer composite for uncooled infrared detector and energy harvesting, using volume fraction, depolarization coefficient of particles and dielectric constants of the constituents.

Conventional ductile iron (DI) and austempered ductile iron (ADI) alloys
were successfully produced. The alloying elements—Ni, Mo, Cr and Mn were added
to get as-cast low-alloyed ductile iron (LADI) followed by austempering heat
treatment. Hardness was measured for all investigated alloys. A hardness conversion
table was deduced for irons investigated. Highest values of calculated quality
index (QI) were for ADI alloys implying higher material performance. Impact
energy values were attributed to...

Contemporary scientific view of micro- and
macro-world was built on a chain of successive hypotheses, each link of which
has no reliable evidence. The examples of scientific concepts “Big Bang” and “neutrino”
show the formation of erroneous hypotheses that lead to the emergence of these
concepts. In addition, the accepted hypotheses lead to the emergence of new
objects of scientific vision of the world, which in the real world are absent.
The paper proves the fallacy of hypotheses about the depe...

Lithium ferrites have attracted
considerable attention because they have been used as replacements for garnets
due to their low cost. A series of polycrystalline ferrite samples with the
composition of LixZn0.6-2xCu0.4Fe2O4 (x = 0.05, 0.1, 0.15, 0.2, 0.25, 0.3)
at different chemical reaction temperature (100℃, 125℃ and 150℃) were
prepared using non-conventional microwave sinterin
