Characterization and aging study of currency ink and currency canine training aids using headspace SPME/GC-MS

Solid-phase microextraction/gas chromatography-mass spectrometry (SPME/GC-MS) was used to characterize the volatile components associated with U.S. currency, U.S. currency inks, and Canadian currency. Compounds that can be attributed to the ink-curing process include series of straight-chain aldehydes, alkenals, acids, alcohols, and ketones and a series of lactones and 2-alkyl furans. Solvent compounds include naphthenic and paraffinic hydrocarbons with a profile typical of petroleum products, alkyl cyclohexanes, various ethylene glycol alkyl ethers, and traces of chlorinated solvents. Trace levels of 2-phenoxyethanol, a solvent often used in ink formulations, were also detected. Environmental contaminants, those compounds found in circulating currency but not in currency ink, include 2,2'-diethyl-1,1'-biphenyl, methyl benzoate and salicylate, menthol, limonene, dimethyl and diethyl phthalate, and ionol. Not including simple hydrocarbons, over 100 compounds were identified in the headspace of currency-related samples.     

Practical benzylation of N,N-substituted ethanolamines related to chemical warfare agents for analysis and detection by electron ionization gas chromatography–mass spectrometry

The benzylation of three low molecular weight N,N-disubstituted ethanolamines related to chemical warfare agents (CWAs) to furnish derivatives with improved gas chromatography-mass spectrometry (GC-MS) profiles is described. Due to their low molecular weight and polar nature, N,N-disubstituted ethanolamines are notoriously difficult to detect by routine GC-MS analyses during Organisation for the Prohibition of Chemical Weapons (OPCW) proficiency tests (PTs), particularly in scenarios when they are present at low levels (~1–10 ppm) amidst more abundant interferences. Our studies revealed that the optimal derivatization conditions involved the treatment of the ethanolamine with benzyl bromide in the presence of an inorganic base (e.g., Na₂CO₃) in dichloromethane at 55°C for 2 h. This optimized set of conditions was then successfully applied to the derivatization of N,N-dimethylethanolamine, N,N-diethylethanolamine and N,N-diisopropylethanolamine present separately at 1 and 10 μg/mL concentrations in a glycerol-rich matrix sample featured in the 48th OPCW PT. The benzylated derivatives of the three ethanolamines possessed retention times long enough to clear the massive glycerol-containing matrix interferences. The protocol herein is introduced as an alternative method for derivatization of these CWA and pharmaceutically important species and should find broad applicability in laboratories where routine forensic analysis is carried out.     

Inter-Agency Cooperation to Raise Awareness on Human Trafficking in Vietnam: Good Practices and Challenges

Awareness-raising tactics are arguably the first priority in the prevention strategies in Vietnam at present. Awareness-raising campaigns are implemented through two kinds of communication methods: community-based activities and mass media. Although anti-trafficking activities in Vietnam have achieved some successful results, recent evidence suggests that a lack of clear progress in the areas of trafficking awareness-raising still remains. The quality and extent of collaboration between authorised agencies are key factors in anti-trafficking activities, including raising awareness on human trafficking. However, to date, there has been no systematic research on inter-agency cooperation in awareness-raising activities in Vietnam. This paper first reviews the nature of human trafficking and legal framework on raising trafficking awareness in Vietnam. The paper then presents successes and challenges of current inter-agency collaborative activities undertaken to implement the awareness-raising strategies.     

GOING TO COURT AS A LAST RESORT: ESTABLISHING A DUTY FOR ATTORNEYS IN DIVORCE PROCEEDINGS TO DISCUSS ALTERNATIVE DISPUTE RESOLUTION WITH THEIR CLIENTS

This Note advocates for the creation of a uniform ethical requirement that all attorneys in divorce proceedings involving children inform their clients about alternative dispute resolution (ADR), particularly mediation and collaborative law. By emphasizing cooperation and negotiation among the divorcing parents, both mediation and collaborative law offer these would-be litigants the opportunity to move forward with their parental duties long after the divorce is finalized. Using the ABA Model Rules of Professional Conduct as a template, this ethical requirement will ensure that clients are fully informed of the availability of ADR and of the chance to forgo potentially unnecessary litigation. Ultimately, the implementation of an ethical requirement holds the potential to minimize the impact of divorce on children by facilitating the process of moving forward for the family as a whole.
