“…8,9 14 C serves as a natural indicator for differentiating between biogenic and fossil carbon. This is due to the fact that the 14 C content in biomass remains consistent with atmospheric CO 2 levels as a result of continuous carbon exchange with the atmosphere. Conversely, the 14 C content in fossil carbon has significantly decayed over billions of years during its formation.…”

Increased utilization of biomass gasification gas-coal cocombustion has created a need for an accurate method to measure biomass-coal blending ratios. The inexpensive and costeffective 14 C-liquid scintillation count (LSC) method has attracted worldwide attention. In this study, the blending ratios (in the range of 1−10%) during biomass gasification gas-coal cocombustion were determined using the 14 C-LSC method, and the accuracy and precision were analyzed in detail. Meanwhile, the blending ratio uncertainty caused by inaccuracies in each factor during the calculation process was quantitatively analyzed. The results of the blending ratios showed a perfect linear fit with the actual values. The absolute and relative uncertainties were both less than ±0.43% and ±9.27%, respectively. Additionally, the relative uncertainties of the majority of the groups were less than ±5%. The accuracy of the 14 C-LSC method was not affected by the types of fuel or the blending ratios. The absolute deviation was positively related to the blending ratio, while the relative deviation was negatively related to it. Both deviations decreased with increasing 14 C activity of the biomass gas. The primary factors that influenced the uncertainty in the measured blending ratio were the 14 C activities of the flue gas and the pure biomass. Except for the 14 C activity of biomass, the influence of the other factors on the uncertainty of the measured blending ratio decreased as the blending ratio increased.

A widespread use of biofuels is a key recommendation of the Paris Agreement and leading international organizations. It is an important step to mitigate the global warming effects due to greenhouse‐gas emissions from fossil oils. To this aim, an analytical technique sufficiently cheap and compact, to foster its widespread adoption, is necessary. Herein, it is shown that a compact, laser‐based spectrometer is suitable to replace the few established techniques, which have been used to quantify the biofraction in fuel blends, so far. Measurements of the biogenic fraction in different fuel samples are reported, with a precision of 1% in the whole range (0–100%) of possible blends, confirming a performance comparable to the best existing technique. An onsite‐deployable saturated‐absorption cavity ring‐down (SCAR) spectrometer is used. The results demonstrate the potential of laser‐based instrumentation to do the accurate and precise measurements required for the certification of biogenic content of any hydrocarbon‐based material. Worldwide adoption of such laser‐based technology for biofraction certification can significantly boost the market of biofuels and can prove to be a disruptive methodology for assessing the biogenic content in plastics and polymeric materials.

The economic and political disruption following the collapse of the Roman Empire is an important moment for the cultural and biological history of Western Europe. One of the trends associated this socioeconomic change is the reuse of Roman public monuments for different purposes including funerary ones. The cultural meaning of this practice, occasionally described throughout Europe, is however still unclear. Here, we present a study of a group of burials (N = 10) recently discovered in the Roman amphitheatre (Arena) of Verona (Northeastern Italy) and dating to Early Middle Ages (8th and 9th century AD). Specifically, we address the following research questions: (1) What depositional events are responsible for the observed stratigraphic sequence? 2) Which demographic composition and health condition characterize this sample? (3) What kind of diet characterized these individuals? In order to address these questions, we performed an osteological and isotopic (δ13C and δ15N) study of the skeletal evidence for the assessment of palaeopathological and dietary patterns and a histological analysis for the refinement of age at death and the calculation of the minimum number of individuals (MNI). A 14C study was also performed in order to better define the depositional sequence of these individuals. The results, besides being among the first palaeodietary data for Early Middle Ages in this region, highlight: (a) the funerary use of this location for at least one century; (b) an MNI of 10 individuals of both sexes and different age classes, featuring relatively high frequencies of unspecific stress markers (porotic hyperostosis and linear enamel hypoplasia) and trauma, and (c) a diet characterized by a consistent contribution of C4 plants and a good access to animal proteins. These results suggest a long‐spanning practice and the absence of any selectivity in the choice of these individuals. Finally, isotopic data align with previous studies on Bronze and Iron Age samples confirming a long tradition of alimentary exploitation of C4 plants in this area.
