Abstract Compared to tris(2‐phenylpyridine)iridium(III) ([Ir(ppy) 3 ]), iridium(III) complexes containing difluorophenylpyridine (df‐ppy) and/or an ancillary triazolylpyridine ligand [3‐phenyl‐1,2,4‐triazol‐5‐ylpyridinato (ptp) or 1‐benzyl‐1,2,3‐triazol‐4‐ylpyridine (ptb)] exhibit considerable hypsochromic shifts (ca. 25–60 nm), due the significant stabilising effect of these ligands on HOMO energy, whilst having relatively little LUMO. Despite their lower photoluminescence quantum yields...
The aim of this study was to investigate the effect clomazone herbicide on oxidative stress biomarkers and acetylcholinesterase activity in human erythrocytes vitro conditions. catalase (CAT), superoxide dismutase (SOD) (AChE), as well levels thiobarbituric acid reactive substances (TBARS) reduced glutathione (GSH) were measured exposed (in vitro) at varying concentrations range 0, 100, 250 500 µg/L for 1 h 37 °C.TBARS significantly higher incubated with µg/L. However, erythrocyte CAT AChE...
Abstract BACKGROUND Despite the need to develop new herbicides with different modes of action, due weed resistance, many important classes compounds have been studied poorly for this purpose. Benzoxazoles are considered privileged structures because their biological activities, but phytotoxic activities not received a lot attention until now. RESULTS Double vinylic substitution reactions were carried out furnish four 2‐nitromethylbenzoxazoles and one oxazolidine. Benzoxazol‐2‐ylmethanamine...
Here we present our preliminary studies into the inorganic pigments Han blue (BaCuSi4O10) and purple (BaCuSi2O6) as near-infrared luminescent fingerprint dusting powders. These were developed in ancient China around 800 BCE both show luminescence NIR region. There remains, however, ambiguity literature concerning their photophysical properties. Samples of artist's characterized by optical microscopy, infrared, ultraviolet-visible absorbance spectroscopy. Their performance powders, without...
Forensic science is an essential service in supporting criminal investigations and the justice system. It also has global humanitarian, peace security dimensions making it a key factor achieving several United Nations Sustainable Development Goals. Despite forensic science's universal value, many jurisdictions are at stark disadvantage continued development of with limitations resourcing technological capabilities. To address this challenge, we have proposed concept frugal forensics, which...
Abstract A square‐wave voltammetric method was developed for the determination of creatinine using glassy carbon electrode functionalized multi‐walled nanotubes and doped with copper. Since creatine‐creatinine balance is dependent on pH, linear responses at either pH 4.0 or 7.0 were evaluated allowing versatility in application, covering analyte concentration from limit quantification (0.3 μmol L −1 ) up to 1.200 (pH 4) 660 7). Electrode simple prepare robust routine analysis it used urine...
