Formats and hyperlinks were adapted from the original.</strong></p><div><p>Pyrotechnic delay compositions are formulations designed to create a specific delay time, determined primarily by their burning rate. These compositions are essential in timing energetic events and are used extensively in both civilian and military applications. <a href="javascript:void(0);">(1)</a> This broad usage leads to diverse motivations for studying such materials. In civilian contexts, such as mining, the focus is typically on safety and cost-effectiveness. <a href="javascript:void(0);">(2)</a> For military purposes, reliability and precision are key factors, often with stringent performance requirements. <a href="javascript:void(0);">(3)</a></p><p>Pyrotechnic delay compositions are classified based on their combustion behavior into gassy or gasless types. In confined, sealed and obturated environments, gasless compositions are favored, to avoid gas buildup. <a href="javascript:void(0);">(1,4)</a> However, in unconfined or vented systems, gassy compositions are not problematic. For example, in fireworks, where combustion gases freely dissipate, <a href="javascript:void(0);">(1)</a> or in vented housings like hand grenades or signaling devices, gassy delays are acceptable. <a href="javascript:void(0);">(5,6)</a></p><p>In gassy compositions, the burning rate is influenced by the loading (or consolidation) pressure. Hot gases generated by the chemical reaction penetrate gas channels (voids) in the material, igniting unreacted material through a process known as convective heating. As loading pressure increases, these voids are gradually reduced, which diminishes convection and subsequently lowers the burning rate. In contrast, for gasless compositions, burning is driven by conductive heating, where heat is transferred through direct particle-to-particle contact, leading to the opposite effect. <a href="javascript:void(0);">(7−9)</a></p><p>Historically, up until World War II, black powder served as the foundation for most delay elements. Nowadays, it continues to be utilized for this function and others, but on smaller scales. <a href="javascript:void(0);">(1)</a> Some more recent and traditional formulations for pyrotechnic compositions include fuels like silicon, boron, tungsten, zinc, iron, zirconium, and manganese. Examples of these are Si/Pb3O<sub>4</sub>, <a href="javascript:void(0);">(8,10)</a> B/BaCrO<sub>4</sub> <a href="javascript:void(0);">(8)</a>, W/BaCrO<sub>4</sub>/KClO<sub>4</sub>, <a href="javascript:void(0);">(5,6,11)</a> Zn/PbO<sub>2</sub>, <a href="javascript:void(0);">(12)</a> Fe/BaO<sub>2</sub>, <a href="javascript:void(0);">(13)</a> Zr/KClO<sub>4</sub>, <a href="javascript:void(0);">(8)</a> and Mn/PbCrO<sub>4</sub>/BaCrO<sub>4</sub>. <a href="javascript:void(0);">(14)</a></p><p>Currently, researchers are actively developing several new formulations for pyrotechnic delays. One of the main motivations for this is the need to transform these compositions into “greener” ones. <a href="javascript:void(0);">(1,2)</a> This means that compositions that could cause problems for the environment or human health should be avoided. To achieve this sustainability, the identification and replacement of known or potentially harmful, toxic, and carcinogenic compounds is vital. <a href="javascript:void(0);">(10)</a> Heavy metals, persistent organic pollutants, toxic gases, volatile organic compounds and known causers of human health problems are examples of such substances to be removed. <a href="javascript:void(0);">(2,5,15)</a></p><p>Specifically, there are several attempts to replace lead, barium, chromates, and perchlorates. <a href="javascript:void(0);">(15)</a> The reason is that most of the established delay formulations used today contain these substances. <a href="javascript:void(0);">(2,5)</a> Lead, barium and chromium (contained in chromates) are heavy metals and are known to cause serious health problems in human, specially to nervous, cardiovascular and respiratory systems. <a href="javascript:void(0);">(5,16)</a> Perchlorates are well-documented substances and are used in various pyrotechnic applications. However, they are widely recognized as contributors to thyroid issues. <a href="javascript:void(0);">(5)</a></p><p>From the above, it is clear that modern strategies in pyrotechnics are increasingly focused on developing new materials that prioritize both efficiency and sustainability. This shift imposes numerous restrictions, meaning that formulations must be designed with precise planning and thorough investigation to meet both performance and environmental standards.</p><p>Boron could be considered the ideal fuel for pyrotechnic reactions due to its high energy content. However, it presents combustion issues for its limited reactivity due to boron oxide layer and boron agglomerates formation upon heating. <a href="javascript:void(0);">(17)</a> The boron oxide layer acts as a barrier, hindering oxygen (O) diffusion and consequently limiting the oxidation of boron. <a href="javascript:void(0);">(18)</a></p><p>Boron carbide (B<sub>4</sub>C) is a natural candidate for combustion processes due to its lower ignition point, which is attributed to its higher reactivity. This reactivity stems from the diffusion of carbon (C) particles, which oxidize into gaseous products. These gaseous products create diffusion channels that penetrate the boron oxide layer, breaking down the layer and agglomerates, thereby further improving the reaction. <a href="javascript:void(0);">(18,19)</a> B<sub>4</sub>C presents better combustion properties, with better burning stability and reliable self-propagation, resulting in better combustion efficiency. <a href="javascript:void(0);">(17)</a></p><p>Bismuth trioxide (Bi<sub>2</sub>O<sub>3</sub>) is an attractive oxidizer for pyrotechnic delay compositions due to several advantageous properties. Its high oxygen content and efficient oxygen release facilitate sustained combustion, while its favorable thermal properties, including a relatively low melting and decomposition temperature, ensure that oxygen is available at precisely the right moment to support a controlled reaction. <a href="javascript:void(0);">(20)</a> Additionally, Bi<sub>2</sub>O<sub>3</sub> high density allows for compact formulations, promoting consistent and reliable burn rates. Also, it has a low heat of formation (approximately −582 kJ/mol), which is crucial to minimize the energy required to initiate its decomposition. This enhances the overall reaction efficiency, allowing Bi<sub>2</sub>O<sub>3</sub> to rapidly release oxygen without consuming excessive energy, thus ensuring sustainable and stable combustion. <a href="javascript:void(0);">(8)</a></p><p>In addition to their technical advantages, Bi<sub>2</sub>O<sub>3</sub> and B<sub>4</sub>C offer a significant environmental benefit: they are considered more eco-friendly compared to other materials commonly used in pyrotechnic compositions. Bi<sub>2</sub>O<sub>3</sub> serves as a less toxic alternative to traditional oxidizers like lead-based compounds, reducing the risk of environmental contamination and exposure to harmful heavy metals. <a href="javascript:void(0);">(1,8,16)</a> Similarly, B<sub>4</sub>C contributes to cleaner combustion, producing fewer pollutants and minimizing the environmental impact. <a href="javascript:void(0);">(5)</a> This makes both materials not only effective but also greener choices for sustainable pyrotechnic applications.</p><h4><strong>2. Experimental Section</strong></h4><h5><strong>2.8. Material Characterization</strong></h5><p>Particle and granule size distribution were measured with a <strong>Malvern Mastersizer 3000</strong> (Malvern Panalytical). Scanning Electron Microscopy (SEM) was carried out with a <strong>TESCAN MIRA</strong> (TESCAN) to examine morphology and confirm particle size. A 40 cm<sup>3</sup> combustion chamber was used to analyze pressure profile, quantify solid residues, and collect combustion gases for further analysis. Fourier Transform Infrared Spectroscopy (FTIR) was performed using a <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/2392"><strong>Nicolet iS50 FT-IR</strong></a> (Thermo Scientific) and standardized nitrogen (N<sub>2</sub>) background to identify gas-phase products. Thermal stability and water content assessments were conducted using <strong>TGA</strong> (NETZSCH TG 209 F3 Tarsus) and <strong>DSC</strong> (NETZSCH DSC 200 F3 Maia). Energy Dispersive X-ray Spectroscopy (EDS) was performed using a <strong>Bruker Quantax 200</strong> (Bruker) for semiquantitative chemical composition analysis of the combustion residues. X-ray diffraction (XRD) analyses were performed using a Rigaku MiniFlex diffractometer for complementary phase identification, while surface chemical states were characterized by X-ray photoelectron spectroscopy (XPS) using a Scienta Omicron ESCA2SR system.</p><h4><strong>3.

FTIR Analysis of Combustion Gases</strong></h5><p><a target="_blank" rel="noopener noreferrer" href="https://pubs.acs.org/doi/10.1021/acsomega.5c10964#fig10">Figure 10</a> compares the FTIR spectra of combustion chamber gases from stoichiometric (blue) and fuel-rich (red) tests, highlighting CO and CO<sub>2</sub> as the main species, consistent with Horiuchi. <a href="javascript:void(0);">(18)</a> Normalizing their absorbance to concentration using standard references yielded CO<sub>2</sub>/CO ratios of 0.67 (stoichiometric) and 0.34 (fuel-rich). However, a quantitative analysis is approximate and inherently imprecise, as potential contamination during gas collection and measurement could affect the results, given the challenge of maintaining a completely controlled internal atmosphere. A small fraction of hydrocarbon species (e.g., CH<sub>4</sub>, C<sub>2</sub>H<sub>4</sub>, and C<sub>2</sub>H<sub>2</sub>) was also identified in both samples.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/ACS_Omega_2026_11_3_4668_4683_Figure_10_Comparative_FTIR_spectra_of_combustion_gas_compositions_in_a_combustion_chamber_ac7b7daf84.jpg" alt="ACS Omega 2026, 11, 3, 4668–4683: Figure 10.

Notably, the identified gaseous products are relatively simple and exhibit low toxicity compared to halogenated or metal-containing species commonly found in traditional pyrotechnic formulations, supporting the potential of this system as a more environmentally friendly alternative.</p><p>Since the reaction involves both condensed-phase reactants and products, characterizing the solid residues is essential to evaluate the extent of reaction and gain insight into the actual progression of the reaction pathway. For this, SEM imaging and EDS analysis were employed to investigate the morphology and elemental composition of the combustion residues.</p><h5><strong>3.8.

A2 showed more Bi<sup>3+</sup> than B4, supporting that the stoichiometric composition had more residual Bi<sub>2</sub>O<sub>3</sub>, while the fuel-rich B4 sample promoted greater reduction to Bi<sup>0</sup>. The presence of Bi<sup>3+</sup> on the surface observed may result from postcombustion reoxidation of Bi<sup>0</sup>. These results reinforce the proposed reaction pathway and the role of fuel excess in enhancing reaction completeness. In this analysis, the B 1s spectrum further confirms the absence of BN by the lack of B–N peaks, consistent with the EDS results, which also revealed no detectable nitrogen signal.</p><p>All experimental findings contribute to the fundamental understanding of boron carbide and bismuth oxide reactions under both basic and applied conditions, particularly in delay compositions. These results provide new insights into the reaction pathway and the underlying combustion mechanism.</p><h4><strong>4. Conclusions</strong></h4><p>Stoichiometric formulations of B<sub>4</sub>C/Bi<sub>2</sub>O<sub>3</sub>, which ignited when not pressed, failed to burn after being lightly compacted; a fuel-rich composition is necessary to ensure combustion. The fuel-rich compositions ignited readily and maintained combustion without quenching. Water facilitated the granulation process and improved the final composition. With increasing loading pressure, burning rates decrease due to reduced convective heat transfer, leading the combustion process to transition toward a conductive regime. Particle size also impacted combustion, particularly with larger Bi<sub>2</sub>O<sub>3</sub> particles, which influenced the combustion profile up to a certain threshold. Additionally, the granule size of the final composition was found to alter the burning behavior, with larger granules promoting faster combustion at lower pressures.</p><p>Thermodynamic calculations provided an initial insight into the reaction process. The findings show that the reaction progresses through distinct stages: starting in a solid–solid preignition phase, transitioning to a solid–liquid phase as components melt, and culminating in a gas phase marked by significant product volatilization, illustrating a complete combustion evolution.</p><p>FTIR analysis confirmed that the main gaseous products are CO and CO<sub>2</sub>, indicating reduced environmental toxicity. Elemental and phase analyses confirmed that the reaction followed the expected pathway, with Bi and B<sub>2</sub>O<sub>3</sub> as the predominant products. No Bi<sub>2</sub>O<sub>3</sub> was detected by XRD, indicating that the oxidizer was fully consumed in the bulk. Morphological analysis of the products suggests that, upon cooling, bismuth solidifies into small metallic spheres, while surface analysis indicates that B<sub>2</sub>O<sub>3</sub> remains predominantly in the outer layer. Altogether, the results are consistent and complementary, reinforcing the reliability and scientific rigor of the study.</p><p>All these observations accentuate the necessity of conducting experiments under application-specific conditions. These findings not only enhance our understanding of the combustion dynamics of low toxicity B<sub>4</sub>C/Bi<sub>2</sub>O<sub>3</sub> mixtures but also underscore their potential for practical applications requiring precise delay times and environmental sustainability. The successful use of water as a green solvent further highlights the viability of developing sustainable pyrotechnic compositions. This research advances the field by providing valuable insights into optimizing performance while minimizing environmental impact through careful material selection and process control.</p></div>

<p><strong>Routine chemical analysis typically involves several steps, e.g. selection of procedure, sampling, sample preparation, measurement, result calculation, uncertainty estimation, and reporting to customer. Based on the result, important decisions and actions are taken. The steps before and after the measurement are often referred to as “pre- and post-analytical”. There are many sources of uncertainty associated with this work, some of which can actually limit the overall quality.&nbsp;</strong></p><p><strong>Proficiency testing (PT)</strong> and external quality assessment <strong>(EQA) schemes</strong> are effective means of assessing the quality of routine analyses. However, if there are specific procedures, either before or after the measurement, which are applied to the routine samples, but not to the PT test sample, the result reflects only the quality of part of the measurement process. Pre- and post-analytical PT/ EQA schemes are already widely used in laboratory medicine. The standard ISO 15189, that underpins accreditation of medical laboratories, stresses that EQA schemes should “... <i>have the effect of checking the entire process including pre- and post-examination procedures</i> ...”&nbsp;</p><p>The examples in this leaflet illustrate the potential and importance of pre- and post-analytical PT/EQA. They are intended as an inspiration for the providers to further develop their external quality control activities.</p><h4><strong>Pre- and post-analytical PT/EQA – a means for harmonisation&nbsp;</strong></h4><p>By illustrating, e.g. lack of adherence to guidelines, or variation in sample preparation, or inconsistency in interpretation, pre- and post-analytical PT/EQA schemes pinpoint problems not apparent in other schemes. This may lead to improved harmonisation and changes to guidelines and standards.</p><h4><strong>Example 1: Interpreting clinical chemistry information&nbsp;</strong></h4><p>Patient background information together with analytical results can be used to check agreement of interpretational advice given by medical doctors. This type of scheme can, therefore, include both pre- and post-analytical aspects. The provider, e.g. through an expert group, ranks the quality of participants’ response and suggestions, and presents them in the report with comments.</p><h4><strong>Example 2: Sampling requests in microbiology&nbsp;</strong></h4><p>Using the scenario of food poisoning, pre- &amp; post-analytical aspects of sampling requests in a microbiology scheme can be highlighted. The provider gives information about food type, symptoms, and incubation time with a simulated sample. Participants choose which organism(s) to test for. The associated laboratory work involves examination of samples, report on method(s) of choice and results. Participants could, e.g. be asked to specify which toxins or pathogens are likely to cause the food poisoning and state whether or not they will disseminate information, e.g. to hospitals or food suppliers. The feedback report would then show the results of each participant together with the comments of the provider.&nbsp;</p><h4><strong>Example 3: Toy testing&nbsp;</strong></h4><p>Faulty design, usage and chance play a role in injury and death incidents related to children’s toys. Toy safety is the practice of ensuring that toys are safe, usually through the application of set safety standards. The PT provider sources a toy, performs visual assessment of its homogeneity, and distributes the samples. Participants are requested to assess the toy against the European standard EN 71 and they have to decide which clauses of the standard apply. The clauses chosen define the test(s) to be carried out. The feedback report will contain a “<strong>model answer</strong>” including clauses, tests and labeling requirements (when applicable).&nbsp;</p><h4><strong>Example 4: Monitoring drinking water quality&nbsp;</strong></h4><p>A post-analytical application can be underpinned by legislation and national regulations (Directive 98/83/EC). Participants receive a synthetic drinking water sample with properties close to one or more limiting values. They are requested to deliver results, uncertainties and a “pass/fail” recommendation to the customer. The recommendations of the provider are listed in the feedback report for educational purposes. Information can be fed back also to regulators to serve, e.g. as basis for further discussions.&nbsp;</p><blockquote><h5><strong>More information / further reading&nbsp;</strong></h5><p>Information about PT providers and schemes can be obtained from your national accreditation body, from the <a target="_blank" rel="noopener noreferrer" href="https://www.eptis.org/"><strong>EPTIS website</strong></a> or from other national or international organisations.</p></blockquote>

Hence it is related to the size of the sample and does not characterize the material itself. The unit of heat capacity, Cp, is Joules per Kelvin (J/K).</li><li><strong>Specific heat capacity</strong> is the energy needed to increase the temperature of one unit of mass of an object by exactly 1 °C. This is calculated by dividing the heat capacity by the sample mass, which provides a more useful characterization of the material. The unit of specific heat capacity, cp, is typically expressed as Joules per gram per Kelvin (J/g/K).</li></ul></div><div><div data-advanced-option="false" data-has-preview-image="false" data-video-id="" data-component-id="2110920040"><div style="max-width:1px;width:100%;" id="mediaContainerWrapper_2110920040"><div style="height:1px;width:1px;" data-external-url="" id="mediaContainer_2110920040" data-advanced-option="false" data-width="1" data-height="1" data-video-id="">&nbsp;</div></div></div></div></div></div></main><div><div><div data-advanced-option="false" data-has-preview-image="false" data-video-id="" data-component-id="2110920040"><blockquote><div><strong>Presenter: </strong>Angela Hammer (Dr. sc. nat.
