Topography and electrostatic interactions of electret fibres in N95 facemasks
Published in Bulletin of Materials Science
Facemasks have been a critical line of defense in the Covid-19 pandemic and have been used for decades to reduce the inhalation of sub-micron aerosols, including bacteria, viruses and nano-materials. These facemasks leverage electrostatic charge properties of non-woven electret fibre mats to remove sub-micron aerosols. However, the topographical an...

Fabrication of gelatin nanofiber webs via centrifugal spinning for N95 respiratory filters
Published in Bulletin of Materials Science
Due to the impact of the Covid-19 pandemic, the usage of numerous protective face masks has faced an explosion in demand around the world. Therefore, the need to reduce the environmental pollution caused by disposable single-use face masks has become vital. Recently, alternative raw material solutions have been discussed to eliminate the consumptio...
Highly efficient degradation of rhodamine B by α-MnO2 nanorods
Published in Bulletin of Materials Science
Manganese dioxide (α-MnO2) nanorods with diameters of about 5–15 nm and lengths of 100–150 nm were synthesized by a simple co-precipitation method, and the degradation mechanism of rhodamine B (RhB) at different pH levels was investigated. The α-MnO2 nanorods exhibited a high efficiency and rapid removal rate of RhB, which reached about 97.5% withi...
Investigation of structural, mechanical and optoelectronic properties of cubic Cd1−x−yZnxHgySe quaternary alloys through...
Published in Bulletin of Materials Science
Structural, mechanical and optoelectronic features of zinc-blende Cd1−x−yZnxHgySe quaternary alloys as well as allied binary compounds and ternary alloys have been investigated through first-principle calculations. Computed elastic stiffness constants ensure that each specimen is mechanically stable, ductile, elastically anisotropic and compressibl...
Growth of brownmillerite Ca2Fe2O5 single crystals under air, oxygen and argon atmospheres using optical floating zone te...
Published in Bulletin of Materials Science
To the best of our knowledge, we report for the first time the growth of brownmillerite Ca2Fe2O5 (CFO) single crystals under Argon (Ar) only ambience by optical floating zone (OFZ) technique and compare its structural and spectroscopic properties with CFO single crystals grown by OFZ method under air and oxygen (O2) atmospheres. Single-crystal X-ra...
Growth of Co-doped ZnO thin films exhibiting room temperature ferromagnetism using a low-cost spray pyrolysis technique
Published in Bulletin of Materials Science
Cobalt (Co)-doped zinc oxide (ZnO) diluted magnetic semiconductor thin films were grown using a low-cost spray pyrolysis technique. X-ray diffraction (XRD) studies show that the films crystallize in the pure wurtzite structure. No evidence of the formation of secondary phases like Co clusters, CoO or Co3O4 were detected from XRD studies. Scanning e...
Weak intermolecular interactions of cysteine on BNNT, BNAlNT and BC2NNT: a DFT investigation
Published in Bulletin of Materials Science
The study of intermolecular interactions is of great importance. This study attempted to quantitatively examine the interactions between cysteine (C3H7NO2S) amino acid molecule with pristine boron nitride, Al-doped boron nitride and carbon boron nitride nanotubes (BNNT, BNAlNT, BC2NNT, respectively) in vacuum. Quantum mechanical studies of such sys...
Low-temperature sintering processes of Mg0.8Zn0.2TiO3 through K0.5Na0.5VO3 and Bi2O3 addition correlated to the dielectr...
Published in Bulletin of Materials Science
This study reports the sintering of Mg0.8Zn0.2TiO3 (MZT) with an addition of K0.5Na0.5VO3 (KNV) and Bi2O3. The sintering temperature was performed at 950°C for 4 h and attained a maximum relative density of 97.71% in a composition of 85% mol MZT–10% mol KNV–5% Bi2O3 (MZT85). Structure, microstructure and phase present in the sample were analysed us...
