“…), while the remaining were between < 0.07 and 9.0, as observed in the literature. 4,[6][7][8][25][26][27] The boron isotopic ratios for Italian, French and South African wines have been reported in the literature, and the obtained values are in agreement with the expected ratios for the two wines sampled first. However, for the South African wines, only the first value fits with the expected value (4.185-4.223), and the other three are much higher.…”

“…Quadrupole inductively coupled plasma mass spectrometry (Q-ICP-MS) has poor precision (relative standard deviation (RSD) = 0.1-0.5%) compared to thermal ionization mass spectrometry (TIMS) (RSD = 0.002-0.005%) and multicollector ICP-MS (RSD = 0.2-0.002%). However, with careful control and optimization of its operation conditions, useful results for wine provenance studies can be obtained by applying Q-ICP-MS. 4,[6][7][8] It should be pointed out that beside lead, which was also applied to Brazilian red wines, 17 other isotopes have been utilized in viticulture, Santesteban et al 9 presented a review about this subject. Delta(D) and delta(O-18) are quite applied to mineral water provenance studies 18 and its use could be extended to detect water addiction in wines.…”

For the first time, the boron isotopic ratio is reported for Brazilian red wines. The boron concentration, 11 B/ 10 B isotopic ratio and δ 11 B were determined in 89 red wines produced in Campanha Gaúcha, Serra Gaúcha ( ). The obtained 11 B/ 10 B ratios were quite different from those observed in the literature. The ratios were quite similar among the Southern Brazilian wine producing areas, but a large difference was observed when compared with the Northeastern wines, allowing for the differentiation between these two important Brazilian wine regions. The results have also shown that is possible, based on the boron isotopic ratio, to differentiate the Brazilian red wines from Chilean, Italian and Portuguese red wine.

“…A higher value of n (smaller value of 1/n) implies an e ective interac- tion between the adsorbent and adsorbate. When 1/n < 1, it corresponds a normal L-type Langmuir adsorption isotherm, while 1/n > 1 re ects a co-operative adsorption (Guo et al, 2016). Since the value of 1/n from this study is 1.33, it indicate that co-operative adsorption may occur in the system, where adsorbed adsorbate has an e ect on the adsorption of "new" adsorbate molecules.…”

To investigate the potential of adsorption and regeneration of natural pumice from West Sumatera Indonesia for total chromium (Cr) removal from aqueous solution, batch experiments in multiple adsorption-desorption cycles were performed. The results indicated that the optimum condition of total Cr removal were 3 of pH solution, 0.3 g/L of adsorbent dose, 60 min of contact time of adsorption, <63 ?m of diameter of adsorbent, and 1 mg/L of total Cr initial concentration with 2.226 mg Cr/g pumice of total Cr uptake. The experimental data obtained were fitted with the Freundlich adsorption isotherm within the concentration range studied. Desorption efficiencies for total Cr ions by using 0.1 M HCl as desorbing agent were in the range of 31-32%. Although complete desorption were not attained, the natural pumice could be sufficiently reused up to 3 cycles of adsorption- desorption with increasing trend in total Cr uptake that may due to the surface modification of natural pumice caused by HCl. Overall results revealed that easy availability of natural pumice as local mineral in West Sumatra, Indonesia and its ability to adsorb and retain total Cr will create more interest to develop new natural adsorption method of pollutant removal from solution.

“…The isotope ratio analysis is an effective method in the field of geographic origin detection. It has been successfully applied to rice [ 39 ], sea bass [ 40 ], red bell peppers [ 14 ], milk [ 41 , 42 ], and wine [ 43 ]. In this study, we have provided the basic data to trace silk origin using the isotope technology.…”

The stable isotope technique provides the possibility to trace ancient textiles because the technique is associated with advantages such as trace indication, fast detection, and accurate results. Since different cocooning conditions may impact cocoons even under identical habitats, it is important to investigate the effects of different cocooning temperatures and humidity on the isotope incorporation values in the cocoons. In this study, silk fibers were reeled under different conditions of temperature and humidity, followed by analysis of the secondary structure of cocoon proteins and isotope incorporation patterns. We found that the deviations in carbon isotope values of silk under different cocooning conditions could reach up to 0.76‰, while the deviation in carbon isotope values at different locations of a single silk was 2.75‰. Further, during the cocooning process, depletion of the 13C-isotope at different locations of the silk fibers was observed, reducing the δ13C values. We proposed that the changes in carbon isotopes in silk were related to the content of sericin and silk fibroin in silk. Finally, we did not observe a significant difference in isotope ratios in degummed cocoons. In summary, the 13C isotope was enriched in sericin, whereas 15N was enriched in fibroin, and these findings provide basic information for tracing the provenance of silks.
