“…In the latter, a precursor solution of a linear polymer is mixed with template molecules to generate specific interactions; subsequently, the solution is precipitated in a proper non-solvent to create robust pearls or membranes [6][7][8]. Since MIPs are robust materials exhibiting low production cost, long-term stability and excellent recognition properties, the interest in employing these materials in many applications, including isolation, biosensors, catalysis, solid-phase extraction, membranes, drug delivery systems and energetic materials has rapidly increased [9][10][11][12][13][14][15]. Hypericum perforatum L. is the most studied of Hypericum genus and it is known for its antidepressant and anti-inflammator y activities, antioxidant and antimicrobial properties [16][17][18].…”

This article describes the evaluation of molecularly imprinted polymers (MIPs) obtained by wet phase inversion for facile separation of hypericins from Hypericum perforatum L. (or Saint John�s Wort, SJW). In this respect, concentrated extracts containing hypericin and pseudohypericin were used as �phyto-templates� for creating selective cavities into the pearl shaped MIPs. The obtained MIPs were characterized by infrared and by thermal analyses. Chromatographic evaluation of the MIPs was performed relative to blank samples and it was concluded that the pearls can retain selectively the hypericins from SJW extracts.

“…Therefore, site characterization, including the investigation of the source and the distribution of various PTEs, is needed most of the time. Regarding the site characterization for the military-impacted areas, the literature mainly focuses on the spatial distribution of PTEs [19,70] and the vertical profiling [7,9,15,26,66,68,[145][146][147] of the impacted areas.…”

Soil Contamination in Areas Impacted by Military Activities: A Critical Review

et al. 2020

Military activities drastically affect soil properties mainly via physical/chemical disturbances during military training and warfare. The present paper aims to review (1) physical/chemical disturbances in soils following military activities, (2) approaches to characterization of contaminated military-impacted sites, and (3) advances in human health risk assessment for evaluating potential adverse impacts. A literature search mainly covering the period 2010–2020 but also including relevant selected papers published before 2010 was conducted. Selected studies (more than 160) were grouped as follows and then reviewed: ~40 on the presence of potentially toxic elements (PTEs), ~20 on energetic compounds (ECs) and chemical warfare agents (CWAs), ~40 on human health risk assessment, and generic limits/legislation, and ~60 supporting studies. Soil physical disturbances (e.g., compaction by military traffic) may drastically affect soil properties (e.g., hydraulic conductivity) causing environmental issues (e.g., increased erosion). Chemical disturbances are caused by the introduction of numerous PTEs, ECs, and CWAs and are of a wide nature. Available generic limits/legislation for these substances is limited, and their contents do not always overlap. Among numerous PTEs in military-impacted zones, Pb seems particularly problematic due to its high toxicity, abundance, and persistence. For ECs and CWAs, their highly variable physiochemical properties and biodegradability govern their specific distribution, environmental fate, and transport. Most site characterization includes proper spatial/vertical profiling, albeit without adequate consideration of contaminant speciation/fractionation. Human health risk assessment studies generally follow an agreed upon framework; however, the depth/adequacy of their use varies. Generic limits/legislation limited to a few countries do not always include all contaminants of concern, their content doesn’t overlap, and scientific basis is not always clear. Thus, a comprehensive scientific framework covering a range of contaminants is needed. Overall, contaminant speciation, fractionation, and mobility have not been fully considered in numerous studies. Chemical speciation and bioaccessibility, which directly affect the results for risk characterization, should be properly integrated into risk assessment processes for accurate results.

“…The importance of finding quantitative, reliable and inexpensive methods to comparatively asses the ignition capacity of primers is more important nowadays, in the context of greener munitions development [8][9][10]. New designed green primers, such as lead-free primers with emerging greener explosives [11,12], are supposed to replace consecrated toxic primers based on lead styphnate, barium nitrate and antimony sulphide.…”

The ignition performances of percussion primers for small calibre ammunition are determined using a new experimental setup, with pressure transducers and special designed combustion chambers. The method enables a comparison of new designed primers with consecrated models by relative ignition capacity. Results show that ballistic performances of primers are in direct relationship with the gradient pressure vs. rise time and also with the maximum pressure developed inside the cartridge chamber.
