The work describes a new chemical means of visualising latent fingerprints (fingermarks) using tropolone. Tropolone reacts with amino acids within the fingermark residue to form adducts that absorb UV radiation. These adducts provide useful contrast on highly-fluorescent prous surfaces will illuminated with UV radiation. The conjugated seven-membered ring of the tropolone adduct can be reacted further diazonium salts, which is demonstrated here with formation of two dyes. The methodology is extremely rapid, occurring in minutes with mild heating, and can be applied before ninhydrin in a chemical detection sequence. <br>

Abstract CBRN (Chemical, Biological, Radiological, and Nuclear) threats are becoming more prevalent, as more entities gain access to modern weapons and industrial technologies and chemicals. This has produced a need for improvements to modelling, detection, and monitoring of these events. While there are currently no dedicated satellites for CBRN purposes, there are a wide range of possibilities for satellite data to contribute to this field, from atmospheric composition and chemical detection to cloud cover, land mapping, and surface property measurements. This study looks at currently available satellite data, including meteorological data such as wind and cloud profiles, surface properties like temperature and humidity, chemical detection, and sounding. Results of this survey revealed several gaps in the available data, particularly concerning biological and radiological detection. The results also suggest that publicly available satellite data largely does not meet the requirements of spatial resolution, coverage, and latency that CBRN detection requires, outside of providing terrain use and building height data for constructing models. Lastly, the study evaluates upcoming instruments, platforms, and satellite technologies to gauge the impact these developments will have in the near future. Improvements in spatial and temporal resolution as well as latency are already becoming possible, and new instruments will fill in the gaps in detection by imaging a wider range of chemicals and other agents and by collecting new data types. This study shows that with developments coming within the next decade, satellites should begin to provide valuable augmentations to CBRN event detection and monitoring. Article Highlights There is a wide range of existing satellite data in fields that are of interest to CBRN detection and monitoring. The data is mostly of insufficient quality (resolution or latency) for the demanding requirements of CBRN modelling for incident control. Future technologies and platforms will improve resolution and latency, making satellite data more viable in the CBRN management field

Abstract The transcription factor AtMYB2 binds to two sequence motifs in the promoter of the Arabidopsis ADH1 gene. The binding to the GT-motif (5′-TGGTTT-3′) is essential for induction of ADH1 by low oxygen, while binding to the second motif, MBS-2, is not essential for induction. We show that AtMYB2 is induced by hypoxia with kinetics compatible with a role in the regulation of ADH1. Like ADH1, AtMYB2 has root-limited expression. When driven by a constitutive promoter, AtMYB2 is able to transactivate ADH1 expression in transient assays in both Arabidopsis and Nicotiana plumbaginifolia protoplasts, and in particle bombardment of Pisum sativum leaves. Mutation of the GT-motif abolished binding of AtMYB2 and caused loss of activity of the ADH1 promoter in both transient assays and transgenic Arabidopsis plants. These results are consistent with AtMYB2 being a key regulatory factor in the induction of the ADH1 promoter by low oxygen.
