Abstract

Barium titanate glass microspheres are used in a variety of applications, particularly for retroreflective materials, owing to their high refractive index. These microspheres can be released into the environment or found at crime scenes due to damage or decomposition. Chemical characterisation of barium titanate glass microspheres using SEM-EDX and LA-ICP-MS showed a good discrimination of the studied materials from each other. The ubiquitously used material has the potential to characterise microtraces at crime scenes or sources of anthropogenically induced particle release in environmental studies, making it a valuable feature.

钛酸钡玻璃微球的 SEM-EDX 和 LA-ICP-MS 化学特性分析的初步结果

钛酸钡玻璃微球具有高折射率，因此被广泛应用于各种领域，尤其是逆反射材料。由于损坏或分解，这些微球可能被释放到环境中或在犯罪现场被发现。利用 SEM-EDX 和 LA-ICP-MS 对钛酸钡玻璃微球进行的化学特性分析表明，所研究的材料之间有很好的区别。这种普遍使用的材料有可能在环境研究中表征犯罪现场的微痕迹或人为诱发的颗粒释放源，因此具有重要价值。

期刊介绍： Forensic Chemistry publishes high quality manuscripts focusing on the theory, research and application of any chemical science to forensic analysis. The scope of the journal includes fundamental advancements that result in a better understanding of the evidentiary significance derived from the physical and chemical analysis of materials. The scope of Forensic Chemistry will also include the application and or development of any molecular and atomic spectrochemical technique, electrochemical techniques, sensors, surface characterization techniques, mass spectrometry, nuclear magnetic resonance, chemometrics and statistics, and separation sciences (e.g. chromatography) that provide insight into the forensic analysis of materials. Evidential topics of interest to the journal include, but are not limited to, fingerprint analysis, drug analysis, ignitable liquid residue analysis, explosives detection and analysis, the characterization and comparison of trace evidence (glass, fibers, paints and polymers, tapes, soils and other materials), ink and paper analysis, gunshot residue analysis, synthetic pathways for drugs, toxicology and the analysis and chemistry associated with the components of fingermarks. The journal is particularly interested in receiving manuscripts that report advances in the forensic interpretation of chemical evidence. Technology Readiness Level: When submitting an article to Forensic Chemistry, all authors will be asked to self-assign a Technology Readiness Level (TRL) to their article. The purpose of the TRL system is to help readers understand the level of maturity of an idea or method, to help track the evolution of readiness of a given technique or method, and to help filter published articles by the expected ease of implementation in an operation setting within a crime lab.
