Removal of iron and manganese from acidic aqueous solution by pyrite and pyrite-calcium sulfite [PDF]

open access: yesScientific Reports
Pyrite and calcium sulfite were used to remove iron and manganese from an acidic aqueous solution. The concentration of Fe was decreased to be smaller than 0.05 g/L in 60 min when pyrite and air were added into the acidic aqueous solution, but the ...

Evading the Illusions: Identification of False Peaks in Micro‐Raman Spectroscopy and Guidelines for Scientific Best Practice

open access: yesAngewandte Chemie, Volume 135, Issue 43, October 23, 2023., 2023
Raman spectroscopy is a great analysis tool but the spectra are sometimes difficult to interpret due to the occurrence of spectral artefacts. This paper dives into the details of many spurious signals and spectral artefacts that occur in Raman spectra, explains their origin, and provides the tools to identify and avoid them.

Inter‐Relationships Between Artistic Creativity and Mental and Physical Illness in Eminent Female Visual Artists: A Qualitative Exploration

open access: yesThe Journal of Creative Behavior, Volume 56, Issue 3, Page 414-431, September 2022., 2022
Abstract Artistic creativity has long been associated with physical and psychological suffering. This phenomenon has also been the subject of empirical research. The anguished “artistic genius” stereotype is ubiquitous, and there is evidence to suggest that artists may have heightened susceptibility to psychopathology.

Raman studies on zoisite and tanzanite for gemmological applications

open access: yesJournal of Raman Spectroscopy, Volume 53, Issue 3, Page 550-562, March 2022., 2022
Raw zoisite and cut tanzanite samples were systematically analysed by Raman spectroscopy. Orientational effects were described to explain spectral variability. Portable and laboratory instruments with different lasers were tested to differentiate photoluminescence contributions and to evaluate the effectiveness of mobile devices for mounted tanzanite ...

Microstructure Characterization of High Explosives by Wavelet Transform

open access: yesMathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
The key macro properties of high explosives including sensitivity to shock, the possibility of initiation, and the subsequent chemical reaction are known to be controlled by processes occurring at their microstructure level. However, there is a lack of an easy, effective, and accurate method to quantify the microstructure, termed as fabric, of high ...
