This review summarizes (i) compositions and types of improvised explosive devices; (ii) the process collection, extraction analysis evidence encountered in related cases; (iii) inter-comparison analytical techniques; (iv) challenges prospects detection technology. The highlights this study include extensive information regarding National & International standards specified by USEPA, ASTM, so on, for explosives detection. holistic development tools ranging from conventional methods to advanced is also covered article. most important aspect make forensic scientists familiar with during steps avoid them. problems can be analyte-based, that is, interferences due matrix or added molding/stabilizing agents, trace amount parent post-blast samples many more. Others are techniques-based viz. specificity, selectivity, sensitivity technique. Thus, it has become a primary concern adopt rapid, field deployable, highly sensitive techniques.

To create an artificial structure to remarkably surpass the sensitivity, selectivity and speed of olfaction system animals is still a daunting challenge. Herein, we propose core-sheath pillar (CSP) architecture with perfect synergistic interface that effectively integrates advantages metal-organic frameworks metal oxides tackle above-mentioned The sheath material, NH2-MIL-125, can concentrate target analyte, nitro-explosives, by 1012 times from its vapour. band-matched enables TiO2 core harvest utilize visible light. At room temperature under light, CSP (TiO2, NH2-MIL-125) shows unexpected self-promoting analyte-sensing behaviour. Its experimentally reached limit detection (∼0.8 ppq, hexogeon) 103 lower than lowest one achieved sniffer dog or all sensing techniques without analyte pre-concentration. Moreover, sensor exhibits excellent against commonly existing interferences, short response time 0.14 min.

Ambient air quality is a complex issue that depends on multiple interacting factors related to emissions coming from energy production and use, transportation, industrial processes, agriculture, waste wastewater treatment sectors. It also impacted by adverse meteorological conditions, pollutants concentrations, their transport dispersion in the atmosphere, topographic constraints. Therefore, distribution not uniform monitoring at proper temporal spatial resolution necessary. Drone-borne analytical instrumentation can fulfill these requirements. Thanks rapid development drone manufacturing sector as well field of portable detectors construction, applications unmanned aerial vehicles (UAVs) for atmospheric pollution are growing. The purpose this work give an overview matter. paper contains basic information UAVs (i.e., description different types drones with advantages disadvantages) low-cost gas sensors, multi-sensor systems, electronic noses, high-accuracy optical analyzers, particle counters, radiation detectors) used airborne pollution. Different ways payload integration addressed examples commercially available solutions given. Examples drone-borne systems natural volcanoes, thawing permafrost, wildfires) anthropological urbanization industrialization; extraction, storage fossil fuels; exploitation radioactive materials; treatment; agriculture) sources described. Finally, current limitations future perspectives discussed. Although there great potential monitoring, several should be years. Future research focus improving performances solving problems insufficient capacity limited flight time commonly drones. We predict drone-assisted measurements will grow following years, especially odor monitoring.

Waste management plants are one of the most important sources odorants that may cause odor nuisance. The monitoring processes involved in waste treatment and disposal as well assessment impact vicinity this type facilities require two different but complementary approaches: analytical sensory. purpose work is to present these approaches. Among sensory techniques dynamic field olfactometry considered, whereas methodologies represented by gas chromatography-mass spectrometry (GC-MS), single sensors electronic noses (EN). latter core paper discussed details. Since design multi-sensor arrays development machine learning algorithms challenging parts EN construction a special attention given recent advancements sensitive layers current challenges data processing. review takes also into account relatively new systems based on mass flash chromatography technologies. Numerous examples applications devices measurements order summarize efforts scientists instruments for constant chosen (composting, anaerobic digestion, biofiltration) nuisance associated with facilities.

The olfactory system can detect and recognize tens of thousands volatile organic compounds (VOCs) at low concentrations in complex environments. Bioelectronic nose (B-EN), which mimics systems, is becoming an emerging sensing technology for identifying VOCs with sensitivity specificity. B-ENs integrate electronic sensors bioreceptors pattern recognition technologies to enable medical diagnosis, public security, environmental monitoring, food safety. However, there currently no commercially available B-EN on the market. Apart from high selectivity necessary compound analysis, commercial must overcome issues impacting sensor operation other problems associated odor localization. emergence nanotechnology has provided a novel research concept addressing these problems. In this work, structure operational mechanisms biomimetic systems are discussed, emphasis development immobilization materials. Various biosensor applications current developments reviewed. Challenges opportunities fulfilling potential artificial biohybrid fundamental practical investigated greater depth.
