The development of highly efficient processes for the cycloaddition CO2 with epoxides to produce five-membered cyclic carbonates is a very attractive topic. In this work, propylene oxide (PO) and give carbonate (PC) studied in microreactor using HETBAB ionic liquid catalyst. performance evaluated by studying effects different operating conditions, including reaction temperature, pressure, residence time, molar ratio CO2/PO, catalyst concentration PO. process characteristics concerning...

Ca-alginate beads were prepared with either external or internal calcium sources. The structures of both investigated the aid scanning electron microscopy (SEM) and confocal microscopy. It was shown that source had a looser structure bigger pore size than those source. attempts to interpret difference carried out by determining Ca content within at various times, which indicated it different gelation mechanisms caused beads. Furthermore, also found diffusion rate haemoglobin (Hb) an faster...

This article reports a novel preparation of nearly monodisperse spherical aggregates CeO2 nanocrystals by using ionic liquid (1-hexadecyl-3-methylimidazolium bromide, C16MimBr) as both template and solvent. The products were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), high-resolution TEM (HRTEM), photoelectron spectroscopy (XPS), Raman spectroscopy, UV−vis FT-IR N2 adsorption−desorption methods. aggregates, average diameter 100 − 150...

Flooded rice fields are an important source of the greenhouse gas CH4. Possible carbon sources for CH4 and CO2 production in soil organic matter (SOM), root (ROC) straw (RS), but partitioning flux between different is difficult. We conducted experiments using microcosms planted with rice. The was amended without 13C-labeled RS, two RS treatments equal (5 g kg−1 soil) δ13C RS. This procedure allowed to determine from each three (SOM, ROC, RS) by determining incubations Partitioning indicated...

In animals and plants, organ shape is primarily determined during primordium development by carefully coordinated growth cell division 1-3 . Rare examples of post-primordial change in morphology (reshaping) exist that offer tractable systems to study mechanisms required for organ-shape determination diversification. One such example the heart-shape formation Capsella fruits occurs reshaping ovate spheroid gynoecium upon fertilization 4 Here we use whole-organ live-imaging show dynamic...

Gut microbiota can promote the resistance of host arthropods to low-temperature stress. Female Pardosa astrigera have a lower anti-freeze compound level and weaker cold temperatures than males in winter, which implies that their intestinal bacteria may be different during overwintering. This study primarily compared bacterial communities between two sexes P. temperate region using 16S rRNA gene sequencing. Our findings indicated Chao1 Shannon indices females were significantly higher those...

Abstract Polymerization induced self-assembly (PISA) has a high solid content, simple operating steps, and can generally achieve conversion to monomers in short time, which been widely used the preparation adjusting morphologies of polymer micelles self-assembly. In this article, applications polymeric micelle synthesized by PISA were reviewed. The particle morphology be adjusted variety active polymerizations with different initiation mechanisms micelles. Among them, free radical...
