Adsorption of propane, propylene and isobutane on a metal–organic framework : molecular simulation and experiment

The separation of propane/propylene mixtures is the most energy-intensive operation practiced in the petrochemical industry. Adsorptive processes are currently viewed as a promising alternative to cryogenic distillation for the separation of these mixtures. In this paper, we explore the possibility of using a new metal-organic framework material, CuBTC, in adsorptive separation processes, particularly in a simulated moving bed (SMB) context using isobutane as a potential desorbent. A gravimetric method has been used to measure the adsorption equilibrium isotherms of propylene, propane and isobutane onto a commercial CuBTC powder over a temperature range from 323 to 423K and pressures up to 100kPa. These were complemented by a detailed experimental characterization of the structure of CuBTC using XRD and SEM techniques. Comparison of experimental isotherms with grand canonical Monte Carlo simulations in CuBTC showed that propane adsorption occurs preferentially in small octahedral pockets, while isobutame is excluded from these pockets due to its bulky structure. Propylene was seen to interact strongly with unsaturated metal sites, due to specific pi-Cu bonds. These interactions significantly enhance the affinity of this MOF for unsaturated hydrocarbons. Furthermore, in a range of temperatures and pressures, the affinity of CuBTC for isobutane is intermediate to that of propane and propylene. Our results suggest that CuBTC-isobutane is a very promising adsorbent-desorbent pair for use in SMB processes for propane/propylene separations

Contribución de la red de seguimiento de la calidad de los ríos guipuzcoanos al conocimiento de la distribución de los Odonata de Gipuzkoa (España)

Se aportan datos sobre la distribución de las especies de odonatos reófilos procedentes del análisis de las larvas incluidas en las muestras de macroinvertebrados bentónicos recolectadas en las campañas de seguimiento de la calidad de los ríos de Gipuzkoa (España) de los últimos años. Son especialmente interesantes las citas de Coenagrion mercuriale (Charpentier, 1840), Onychogomphus forcipatus forcipatus (Linnaeus, 1758), Onychogomphus forcipatus unguiculatus (Vander Linden, 1820) y Oxygastra curtisii (Dale, 1834). Contribution of the Guipuzcoan river quality monitoring network to the knowledge of the distribution of Odonata in Gipuzkoa (Spain) Abstract: Data on the distribution of rheophilic Odonata are presented, extracted from the analysis of the larvae included in the samples of benthic macroinvertebrates collected in a series of river quality monitoring campaigns conducted in Gipuzkoa (Spain). Records of special interest are those of Coenagrion mercuriale (Charpentier, 1840), Onychogomphus forcipatus forcipatus (Linnaeus, 1758), Onychogomphus forcipatus unguiculatus (Vander Linden, 1820) and Oxygastra curtisii (Dale, 1834)

Do experimental subjects favor their friends?

Ideally we would like subjects of experiments to be perfect strangers so that the situation they face at the lab is not just part of a long run interaction. Unfortunately, it is not easy to reach those conditions and experimenters try to mitigate any effects from those out-of-the-lab relationships by, for instance, randomly matching subjects. However, even if this type of procedure is used, there is a positive probability that a subject may face a friend or an acquaintance. We find evidence that social proximity between subjects is irrelevant to experiment results in dictator games. Thus, although ideal conditions are not met, relations between subjects do not contaminate the results of experiments.friendship effect, dictator game, experimental procedures, fairness

Tomato- Fusarium oxysporum interactions: II. Chitosan and MSB induced resistance against fol in young tomato plants

Qitosna, hidrolizados de quitosana y menadiona bisulfito de sodio (MBS), fueron aplicados al suelo y asperjados sobre plantas de tomate en diferentes experimentos, para evaluar su efecto combinado sobre el desarrollo de la enfermedad. Los tres productos protegieron con efectividad las plantas contra la enfermedad, mostrando los mejores resultados la aspersión al follaje con hidrolizados de quitosana y MBS (0.25 + 0.05 g.L$ respectivamente), sugiriendo que la inducción de resitencia sistémica juega un papel importante como mecanismop de defensa del tomate contra el ataque de Fusarium oxysporum f.sp lycopersicil (FOL). Se midierojn algunos mecanismos enzimáticos relacionados con la defensa en plantas tratadas con elicitores e inoculadas con FOL como marcadores de resistencia a la enfermedad.We gratefully acknowledge the fine technical assistance of Oligosaccharins Laboratory and the collaboration of the Technological Development Laboratory from CIGB.

Health promoting properties of bee royal jelly: Food of the queens

Royal jelly (RJ) demand is growing every year and so is the market for functional foods in general. RJ is formed by different substances, mainly carbohydrates, proteins, and lipids, but also vitamins, minerals, and phenolic or volatile compounds in lower proportion. Major royal jelly proteins (MRJP) are, together with 10†hydroxy†2†decenoic acid (10†HDA), key substances of RJ due to their different biological properties. In particular, 10†HDA is a unique substance in this product. RJ has been historically employed as health enhancer and is still very relevant in China due to the traditional medicine and the apitherapy. Nowadays, it is mainly consumed as a functional food or is found in supplements and other formulations for its health†beneficial properties. Within these properites, anti†lipidemic, antioxidant, antiproliferative, antimicrobial, neuroprotective, anti†inflammatory, immunomodulatory, antiaging, and estrogenic activities have been reported for RJ or its specific components. This manuscript is aimed at reviewing the current knowledge on RJ components, their assessment in terms of authenticity, their biological activities, and related health applications.The research leading to these results was supported by FEDER under the program Interreg V-A Spain-Portugal (POPTEC) 2014–2020 ref. 0377_IBERPHENOL_6_E and ref. 0181_NANOEATERS_01_E; by Xunta de Galicia supporting with the Axudas Conecta Peme the IN852A 2018/58 NeuroFood Project and the program EXCELENCIA-ED431F 2020/12; by EcoChestnut Project (Erasmus+ KA202); by Ibero-American Program on Science and Technology (CYTED—AQUA-CIBUS, P317RT0003) and by the Bio Based Industries Joint Undertaking (JU) under grant agreement No 888003 UP4HEALTH Project (H2020-BBI-JTI-2019) that supports the work of P.
